What speed will my not too great line get?

So i have paid £5 extra a month to uncap my line. I can withdraw from the new contract within 30 days if my line doesn't increase over 40meg. My ISP Sky have said it will hit 50meg max. Here are my stats i know the guys on here are a lot smarter.

Broadband Link Downstream Upstream
Connection Speed 39999 kbps 9999 kbps
Line Attenuation 21.7 dB 0.0 dB
Noise Margin 10.3 dB 6.6 dB

Ignore the 0.0db on line attenuation upstream it's a common Sky hub issue that it fails to show it. Nothing to do with my line.

What estimate does www.dslchecker.bt.com give for your line?

Hi, It seems since my line is with Sky it won't work accept with the address checker or postcode checker which it warns is less accurate.

address checker says.


WBC FTTC 18x2 Sim Availability
High Low High Low
VDSL Range A (Clean) 47.9 35 10 6.8 32.4 Available -- -- Yes
VDSL Range B (Impacted) 38.5 22.2 9 5 16.5 Available -- -- Yes

Postcode checker doesn't even mention fibre however i am already using 40meg Fibre and it has been around this area a while now.

There is literally 0 point in upgrading, stay on the 40/10 package, not worth the extra money for 7Mbps more.

Not to me this house is very heavy usage any speed increase will help. If it increases by just 3-4meg or something i will switch back before the 30 days. If it increases to 47 or above I'll take it. Before i got fibre my line used to hang around 7-8meg on ADSL. Lived with that for years.

That's why the postcode checker is useless. Many postcodes are served by a few cabinets located around it and also covering neighbouring codes. That checker only reports the first in the database.

if you enter only the postcode into the address option and press "Submit" or whatever, you will get a dropdown of all addresses in the postcode.

If you click on each in turn you will see the cabinet numbers (on the line above the table) are not all the same and some like you will have VDSL2 available and others not. Usually but not always, all those on a common cabinet will be enabled. But sometimes a address on that cabinet will be too far from it.

That is a great answer for that checker but doesn't really help my question. Am i likely to hit close to 50 say 47+ with my stats or will i end up having to downgrade within the 30 days back to standard 40meg?

Well those are the estimates you have: 47.9-50 Mbps

All you can do is try it and see.

Thanks well heres for hoping to get 47+

Given your attenuation you will certainly get a few Mbps, but how many only time will tell. Bear in mind that higher speeds result in higher error rates, which could cause DLM to mess about a bit.

How do i prevent this if it is possible? I see your line is Sync 54999 so 5 to 8meg faster than mine can apparently get. How do you say keep it stable at 54999?

This is not likely to slow it down is it? under 40meg?

Different lines, different lengths so not always possible to compare unless lots more information known.

Only way to know is to try, and this does carry the risk the change will be marginal and DLM if it sees errors could potentially see you dip below existing speeds. In short no guarantees and if the existing sync is very stable, stay where you are would be my advice.

If household usage is pushing things, then with fibre packages starting at around £24/m might be better getting a second line and putting some devices on one, and others on the other.

Ignore the 0.0db on line attenuation upstream it's a common Sky hub issue that it fails to show it. Nothing to do with my line.

My rule of thumb is that each 3dB of "spare" downstream noise margin is worth
- about 10-11Mbps for a line that is already achieving 65Mbps
- about 8Mbps for a line that is achieving 40Mbps
- about 6Mbps for a line already achieving 25-35Mbps.

You have 4.3dB of spare downstream noise margin, so I'd guess you could get between 8 and 12Mbps extra.

Upstream, you aren't likely to get much extra at all.

Remember that you'll then likely to be running at the set target noise margin of 6dB. If more subscribers join, you might suffer more crosstalk, and so the speed you get on day 1 could slowly erode.

I think that's slightly ambitious, the downstream rate didn't increase by 8 Mbps on my line, but then it's starting to become unstable.

Edited by deleted (Tue 14-Feb-17 16:07:56)

Did you have 4.3dB spare on the downstream though. I can't see from MDWS as your line was banded at 35mb for so long.
What value are you using to compare your line with the OP's?
Some upgrading would get the full 80mb, others would get nothing.
It entirely depends on the individual line, but I'm curious as to what you are using you make a direct comparison to your line.

No, I'm talking about when the downstream SNR margin went from 6 to 5 to 4 and then to 3 dB on my line. I'm using the example WWWombat gave. I'm putting the lack of increase down to slow degradation in quality.

Edited by deleted (Tue 14-Feb-17 16:43:27)

WWWombat wasn't discussing anything to do with target SNRMs. He was referring to the fact the OP is capped at 40mb with an SNRM of 10.3dB, so there's 4.3dB spare.
He's guessing the OP would get 8mb more if they upgraded package, and removed the 40mb cap.

Hmmm. I think you are treading close to nit-picking.

Your line was at its slowest when DLM reset you back to an old-style INP=3 setup: 36.4Mbps.
I'll ignore that speed - my rule-of-thumb doesn't reflect major changes in INP.

DLM then activated G.INP with a 6dB target. Your line synced at 41Mbps. We'll use that as a baseline.

The trial then altered your line, in steps, down to a 3dB target. When that happened, your speed increased to 48Mbps

I make that an increase of 7Mbps. That's not too far off the rule-of-thumb, is it?

Your line resync'ed last night, staying at a 3dB target, but shaving 1Mbps off the sync speed. Should I use 6Mbps?

No, because...

It must be remembered that your line varies by 1 dB across the day; yesterday's resync was at a time that your SNRM is typically 0.5dB below its peak value - which tends to happen around midday. The previous resyncs have tended to be at times when the SNRM is at its peak. That easily explains a 1Mbps difference.

As you mention, your line is seeing *something* happen - audible on the phone, and visible in the error rates if not in the SNRM figures. That kicked in after the 6dB margin was used, but before the 3dB margin was used, and may be having some impact. Unfortunately, unquantifiable.

Overall, I remain happy with my rule-of-thumb.

Fair enough. I wasn't trying to nit-pick.

This is true.

However, William's line happened to make use of "spare SNRM", though only 3dB, through the 5-4-3dB trial.

I'd expect lines to see roughly(*) similar speed improvements, no matter what method was employed to make use of an extra 3dB margin.

---

(*) My rule of thumb was originally calculated by examining the "bits/tone" graphs at various speeds, and estimating how many tones were in use at different speeds (explained below), but it has proven to be remarkably resilient so far.

As a 3dB improvement in SNRM allows 1 extra bit to be carried per symbol, on each tone, the improved speed comes from multiplying the count of usable tones by 1bit per symbol, by 4000 symbols per second.

A complete downstream set of tones is 2,748 tones. 1 bit on every tone amounts to 11Mbps. That's the best you can hope for.

The gains fall into 3 main bands because of the way spectrum is split:
- 10-11Mbps for lines using D1, D2 and D3
- 6-8Mbps for lines using D1 and D2
- 2-3Mbps for lines using D1

Beyond this, however, there are many variations in behaviour. Some lines get 40Mbps by putting a few bits/tone on a lot of tones - these are likely to gain more than the rule-of-thumb. Some lines get 40Mbps by using a lot of bits/tone on fewer tones, and are likely to gain less by this change. It will depend on the interaction between Hlog and QLN graphs.

Its rough - but that is the definition of a rule-of-thumb, isn't it?

That definitely satisfies the rule of thumb. Thanks for your in depth explanations, WWWombat.

its up to you what you do but an extra £10+ for 7-10Mbps? very very pointless, its only 875Kbps-1.2MB/s more and you wont even notice it imo.

I upgraded from 40/10 to 55/10 and was a very good move, IMO. It allowed my line to be included in the trial!

In reply to a post by WilliamGrimsley:

Is there something in the trial that excludes the 40/10 product? I assumed it would cover most lines irrelevant of product.

I think he means that if he line was capped at 40, then his SNR would be above 6, and thus no need for the trial to make changes?

That makes much more sense! Williams line is like mine where the 55/10 package introduction is ideal. I can't see me benefiting much from the lower target though as I sync around 54/10. I'll get the little 1-1.5mb left.

They done it already.

Noise Margin 6.3 dB 6.6 dB

I'll give it 2 weeks and cancel if it is unstable. Notice upload has slowed.

Give it three days then reboot well inside daylight hours. Steer clear of dawn or dusk. Saturday or Sunday would be ideal. You may get even better in both directions .

There's nothing special about three days, but certainly don't do anything until Friday.

Thanks i will monitor it. Sky say they do DLM for 10 days on the line when a new product is activated. If that is true that could be annoying. I remember them saying that before and nothing happened it just locked at 39999kbit and 9999kbit up and stayed like that sometimes 40000kbit down.

If i reboot router and there is DLM monitoring or running on my line won't i make it think it dropped due to an error and got worse?

Ok this can't be good. I have done 10 speed tests and out of the 10 only 1 gave me over 40meg it is as if my line profile is capped.... but why would one speed test out of the 10 give me the extra 6. whatever meg?

http://www.thinkbroadband.com/speedtest/results.html...
normal 40meg result i used to get.

then.

http://www.thinkbroadband.com/speedtest/results.html...

That one increased to the new sync i had. Then....

speeed test 3

Sky have no active control of DLM beyond which of three DLM profiles are given to a line when ordering.

They are repeating something that is more line with the old ADSL2+ system, and it was never clear if Sky LLU had a 10 day system of its own.

Ok hopefully that will be a good thing but why is my line capping itself to 40meg as if nothing has changed accept with just one speed test. I have now done over 12 and no others have gone over 37meg which is my normal 40meg result.

Sky running an 'ip profile' system of their own?

Sky are annoying. I am synced higher but it has def locked me with a 40meg profile or something. Sync has not changed and latest result.

Latest test

I assume you have done a cold reboot of the router. In the past with Sky when I've switch to a faster package the throughput didn't change until the router was rebooted.

Thanks, i haven't. isn't it normally better to let it reconnect after mid day for fastest speed?

Done. I'll see if it has made a difference to speed.

New sync.

Edit: Nope still artificially capped somehow

still the same

Edited by deleted (Wed 15-Feb-17 10:23:23)

Yes, that's correct. Or when the downstream SNR margin is at its highest.

(Edit - I see things have moved on since I started this reply. Upstream sync has picked up but downstream fallen. Leave it alone for now ).

Very odd, and annoying for you.

As MrSaffron says, there is no direct DLM control by Sky on FTTC, but it is possible they are running some sort of IP Profile system of their own. At one point, maybe even these days, people going on ADSLx with them would be started at exactly 4Mbps then ramped up in two or three steps over the next few days. (On their LLU ADSLx they do have direct DLM control as it is completely their system. On FTTC the only DLM is Openreach's).

Those speed tests do look like a solid cap but lower than I would expect even for 40Mbps. Keep an eye on the sync speeds - have you checked it hasn't reverted to 40000?

I'm not sure whether you should do the re-sync I suggested, or perhaps wait the ten days, or a power cycle of the router as has also been suggested. Maybe do that in broad daylight on Saturday, leaving the router turned off for maybe 30 minutes when you do.

Edited by RobertoS (Wed 15-Feb-17 10:32:16)

I power cycled the router to get the 2nd new sync and it stayed the same. I guess i may have to phone Sky again if this cap there end does not go. The speed results i am getting are about exactly the same as i had with 39999kbit sync.

See my latest version of my edit at the start of my previous post .

Thanks. I will reboot it next on Saturday.

Is this correct for my last sync?

no sync change it did this on its own

edit: its gone back slow again. spoke to soon.
sync is still the same. That cap re kicked in. I dont understand this. All tests are doing this again.

Strange all with no sync change

Edited by deleted (Wed 15-Feb-17 12:06:03)

You'd better just wait and see. Sky are clearly doing something automated, so don't interrupt it . Leave it the ten days they said. You have plenty of time after that to revert to 40/10.

I will leave it and see what happens. I might try a 2nd reboot on Saturday not 100% sure yet.

I have noticed a strange pattern that i can't help but think is very odd. If i hardly use the connection for an hour and do a speed test i get the full sync speed in the test like two i have posted above that did get higher speeds. Every single time i do a 2nd test straight after it drops back down to that 37.4 to 37.8 area that i used to get.

It is a perfect pattern it has occurred 4 or 5 times now. I guarantee if i just leave my connection idle for an hour from now and do a speed test i will get the sync speed again, then if i repeat instantly it will immediately drop to 40meg cap.

Tell me that is not odd?

It slowed back down here mid speed test. When it switched to 6 thread part of the test it instantly slowed down and netmeter showed it too. Check out the yellow part of the test.

Caught it instantly capping itself mid speed test

Edit: an hour is a rough estimate of the time it takes between tests before they show the higher sync speed. It may be less but if i keep repeating them every 10 minutes i never get full sync speed. If i wait much longer i do! instantly after back to normal again. I would also like to point out that the entire time router is connected and not disconnecting. It has been up since i last rebooted it which is posted above. The sync speed is remaining identical throughout all these speed tests.

Could be traffic management kicking in perhaps.

In reply to a post by RobertoS:

Sky do not do traffic management if you mean throttling and such. like i said i know other people in my area with FTTC one has Sky and gets around 58meg or so sync and gets that sync speed 24/7.
I talked to him on whatsapp. He said he never had Sky fibre normal 40/10 he started straight away on pro. It was not like my experience. He said it started at 60 and dropped to 58 and stayed there. No 40meg throttle and speed was always with sync connection speed.

I "know" they don't . But I'm querying if that is 100% true on the 80/20 they don't try hard to sell.

It is a £5 increase not £10

I proved my point that it speeds up. I didn't do speed tests for over an hour and now two speed tests got the new sync speed.

About right for what router is synced at
It may not be amazingly faster than 40meg and i don't know if I'll keep it or revert etc but it is def stable when it runs at the proper sync speed.

If i keep downloading or doing speed tests it will suddenly slow to 40meg without router disconnecting or changing its connection speed etc. I just further proved that if i leave it alone it seems to go up to the sync speed.

The repeatability makes this seems like suspicious behaviour.

If I were cynical, I'd say it looks like someone is doing traffic management, but in a fashion that they hope to be undetectable to people running speedtests.

How accurate is "the hour" thing? Do you see slowdowns with 55 minute intervals, but not at 60 minutes?

I said in a previous post i am not sure on the time frame between tests going back to full speed. However if Sky were doing this on purpose it is not very sneaky of them at all. It can kick in after just 1 speed test or a 1-2 minute max speed download. I can't see it being throttling or we would see a lot more people complaining.

Saying stuff like "why does my download speed drop to 40meg every time i do large downloads or multiple speed tests?"

I am going to wait it out a while and see what happens. Unbelievably that tiny increase actually helps Youtube 4K HDR vids on my 4K TV start at 4K HDR straight away.

It seems Youtube 4K likes 42meg better than 40meg. After just one youtube vid i am back down to 40meg again tho.

My line has remained synced as it was when i rebooted earlier yesterday.

Connection Speed 46211 kbps 10165 kbps
Line Attenuation 21.8 dB 0.0 dB
Noise Margin 6.4 dB 6.6 dB

connection up time 20 hours 13 minutes at time of writing this.

OK now i am really annoyed. For the 2nd time in 3 years i have a crossed line. Since the FTTC change we are hearing other people talk on our phoneline there conversations etc and some of them if not all can hear us too.

This is the 2nd time my line has had a crossed line and it seems the upgrade to Sky fibre pro has made it re occur.

Why has my line always been so bad. Everything has been done to it that can be done including new master socket. I just seem to get insanely bad luck with broadband.

Currently the fibre is still doing what it was yesterday synced at 46meg but switching between sync speed and a seemingly artificial 40meg cap. At the same time now i have a crossed line with more than one other house hold for the 2nd time in 3 years.

Not happy at all.

Not good at all .

New sync by itself around 5am while i was asleep.

So far after 2 speed tests in a row..

Getting sync speed again. FTTC seems unaffected by almost un usable voice line currently

What's wrong with the voice line?

The voice line problem ought to be reported as a fault in its own right. I can't imagine how an FTTC speed uplift (which just involves some parameter and config changes to the VDSL settings) could cause problems with crossed lines. However, I can see how a line fault could cause issues with FTTC, although if the wiring issue is after the splitter in the VDSL cab it could leave BB unaffected.

By "after", I assume you mean E-side? I think most people would read it as D-side .

That's how I read it. To me "after" the splitter is D-Side, "before" is E-Side. The line originates from the exchange, not my property

I'm also confused as to how upgrading from 40/10 to 80/20 has introduced voices on the line. Nothing physical needs touched to perform the upgrade, so no new crossed wires. It's a click of a mouse upgrade.

In context, "after" is after the BB part which stops at the cabinet filter. I was also talking in context of the customer. The is surely no definitive direction "after" or "before" other than the perspective that is being used. I would also suggest it would be inaccurate to call it E side if the problem is in the tie cable connections, either at the FTTC cabinet or the PCP. The "E" side is normally the cable from the PCP to the Exchange.

When there is any possibility of confusion, as in your post, it is better to be specific. Even this latest post is contentious.

The "E" side is normally the cable from the PCP to the Exchange.

Conventionally, before FTTC was invented. It would now make more sense for that and D-side to refer to either side of the DSLAM line card, as that is where the user's signal is generated.

With your definition of E-side, on ADSLx where at the exchange does it end? At the DSLAM/MSAN or the MDF? Similarly with FTTC, where does that E-side end? On the Openreach kit at the fibre headend, or where the CP connects to the GEA cable?

Or where the copper PSTN service ends, perhaps at a different exchange. Which is presumably where you meant, but haven't clearly stated.

An engineer has been booked for tomorrow for the line due to it being so bad. However it really doesn't seem to be affecting my FTTC at all all my stats are the same before the switch like attenuation etc.

My line still sometimes locks to 40meg but since i got a 2nd email from Sky around 11am confirming new contract today it has stopped decreasing in speed artificially. Or maybe its a coincidence. I will be keeping an eye on it. I also have a Sky Fibre support team person phoning me today between 4 and 6pm the same one i talked to Wednesday to check on my line and how it is going.

Something made it crossed with one or two other houses lines by the sound lool. This is 2nd time we have had a crossed line also for some reason it is having no negative affect that I can tell on my FTTC lool.

I have a question to anyone who may know. I do a lot of streaming and other people in the house too hence why i need all the speed i can get. Sky hubs the black SR102 ones don't slow down the max download if you have been streaming does it to help prioritize streaming data?

Also my Local LAN is setup via Sky hub directly connected to master socket vdsl socket. only phone connected to phone part of same master socket, one of the new ones.

But could this next but affect my speeds in anyway. I then have a 1 meter cat5e ethernet cable that came with the Sky hub connected to a 1gbit D link Switch. A new model still sold on Amazon now. Then that Switch is connected to 3 devices in living room and a 4th 30 meter cat6 cable going to my "gaming" room which connects to an identical 8 port 1gbit D link switch in that room that is then connected to a office computer a gaming computer and some games consoles and other stuff. The 2nd 8 port switch only has 2 ports spare in that room.

Here is my question. My switches couldn't have traffic management or prioritization for streaming type data etc over downloads could it?

So network is Sky hub 1 meter ethernet to 8 port D link New model switch which connects to 3 devices then a 30 meter cable from the first switch to a 2nd identical 8 port switch in another room that only has 2 ports spare due to amount of devices connected.

Edit: That is not counting 3 to 4 WiFi devices that connect now and then etc. But i can't see them affecting the speed i even turned WiFi off during some of the speed tests where i was locked at 40meg yesterday.

You mean this?

The DGS-108 is a plug-and-play networking switch that features D-Link�s Green Technology to save energy and reduce heat, which in turn extends product life without sacrificing performance or functionality. The switch supports IEEE 802.3az Energy-Efficient Ethernet (EEE) which can detect when a connected computer is shut down or when there is no Ethernet traffic, and will proceed to power down the idle port, saving a substantial amount of power. In addition, the switch can also save energy by detecting the length of cable connected to a port and use only as much power as is required. Both of these features work together to help you save power automatically.

I also found out how long my line is, Sky engineer on phone said it was 800 meters or just over.

Edit: He meant from my house to the cabinet, not exchange.

I ordered 2x of these switches. After my Sky SR102 hub they run my Ethernet LAN network.

D link switch i use two connected to each other in two differant rooms, one directly connected to the Sky hub.

I'm concerned their energy saving credentials mean they can throttle connections

Conserving Energy

Automatically powers down ports that have no link
Budgets power output for different Ethernet cable lengths
Complies with California's stringent CEC and Australia MEPS regulation requiring the use of more energy efficient power adapters

Saying that i have done FTP between them and my LAN and got over 980mbit at least so they seem pretty damn fast. Also I've had 40meg Fibre for quite some time now and they have been there with it for a lot of that time and never causing any issues. I had a TP link one in the gaming room which i noticed was slower than the D link which is why i got a 2nd one and sold the TP link one on. The TP link one also always kept my connection down to around 750-800mbit between it and the Sky hub when it was in use ages ago before i sold it.

I'm concerned their energy saving credentials mean they can throttle connections

Conserving Energy

Automatically powers down ports that have no link
Budgets power output for different Ethernet cable lengths
Complies with California's stringent CEC and Australia MEPS regulation requiring the use of more energy efficient power adapters

Ok so looking at that more deeply. I can't see the more energy efficient power adapter causing any issues.

I can't see that when it powers down ports that have no link causing any issues because if that was occurring surely i would have no access at all on the device connected to that port, the port would be turned off.

So that leaves only the "budgets power output for different Ethernet cable lengths"

I can connect one computer near router. A I3 PC that isn't too far from the Sky hub directly for future tests. It's Ethernet port is actually very good. Intel chipset 1gbit for testing.

Total current status of my line.
Router stats.

4 in a row speed tests at a rather peak time.

Worth trying a direct ethernet connection just to rule out the switches being a problem

All 4 of them speed tests were through both of the switches!
That result seems about right for my sync doesn't it after you take away the TCP overheads and IPV6 which slows bandwidth down slightly.

So are slowdowns still a problem? If they are use the direct connection to see if that slows down too.

Since i got this seemingly automated reply from Sky today about a new contract the slow downs seemed to have stopped!

I am getting this all the time now. The sync speed.

Question is, is that worth £5 a month more.

Your speed may yet increase if G.INP gets turned on

Nope huge decrease when i woke up today,

Connection Speed 41145 kbps 9234 kbps
Line Attenuation 21.8 dB 0.0 dB
Noise Margin 6.3 dB 5.5 dB

Look at upload lool. Looks like it is going to be back to 40/10 package for me make it go back perfectly stable.

Well that's not worth a fiver

Indeed i have cancelled the new contract with Sky fibre PRO and am now out of contract again That means i am still paying rather a lot for what i am getting. I have done this to keep my options open. Free to switch providers.

So.. Now the BT with there £150 credit card thing offer is becoming very tempting.
I am likely to get 40/10 perfect like i did with Sky with BT aren't I?

Also is BT truly uncapped i have hit 1tb a month on occasions also streaming is 60%+ of that including 4K streaming which 40/10 Sky does well. That is why i am worried about switching.

I can still phone Sky and try and enter a new contract and lower my price if i decide i want to try to stay with them.

Edit: I have noticed something odd that reconnect ion last night before i phoned Sky and cancelled changed my IPV4 IP It was meant to be static and was till that change reconnect

BT is totally unlimited, no restrictions.

Infinity 1 is a 55/10 service so you'll get the best your line can support.

Top cashback/quidco stacks with the £150 gift card too

I am having trouble unless i am missing something obviase finding unlimited calls like i have with Sky upto 1 hour to 01 02 numbers and mobiles for free till the hour is up 24/7) type package with the infinity 1 through quidco.

Edit: Doesn't seem to have free calls to mobiles like i currently have. i did find the package you add unlimited calls later on.

This is very strange i am still on Sky Fibre Pro right so static IP but since last night before i cancelled it reconnected and my IPv4 add changed and i just reconnected again and got 42meg down 9.5meg up and my ip changed again. I'm on Sky fibre Pro currently without a static IP!

It's possible to have a dynamic ip address with sky fibre pro. Sky fibre pro doesn't guarantee a static ip address, you still have to request one.

They neglected to mention that at all on the phone when i switched.

Reconnected again like it does every night.

How long till they downgrade me again? i cancelled fibre pro yesterday.

BT only do free calls to BT mobile numbers you have to pay for calls to any other network. It's one reason I never switched to BT even though they were prepared to pay the early termination fee on my Sky contract.

also that his line may become unstable at 6db snrm and then lose speed for interleaving overhead.

I think he was right, That is what was happening with Sky when they uncapped my line.
I have downgraded and this is it now back to normal... accept it isn't normal. On 40/10 i have never seen it out of a fault at least that struck once do this.

Connection Speed 39973 kbps 9999 kbps not quite 40meg sync 39999 is what it used to always get.

At least i got my upload back to its normal speed.

The speed changes spookily suggest that, yes, the line first gained speed then suffered from old-style DLM intervention. Shame we couldn't see any error rates to confirm.

Certainly not worth the money.

Sky's automated contract emails have got weird. I have had 6 so far and 3 of the 5 say different estimated download speeds. Slowing each time i get one LOL.
Most say 35-40meg estimated download
now its saying 32 in latest email i got today. Also today's email say they downgraded me on the 18th. It was not until yesterday my line dropped from 41-42meg sync to 39978 or whatever weird non 39999kbit speed it went to.

On Saturday when i phoned and told Sky to revert it to normal Fibre not pro about 10mins after the phonecall i got two identical emails from Sky sent within seconds apart.

They were the two that said guaranteed speed 35.2meg max speed 40meg. Since they todays email they sent its dropped to 32 guaranteed download speed.

Phonelines and fibre annoy me so much and i am still out of contract. I am actually thinking of cancelling and not havijng a phoneline. Just a mobile. I could use my mobile for any data i use it would be fine for me just not other people in the house.

Good news there is the other people in the house would be annoyed and one would end up paying for some kind of fibre themselves and I would get it for free. So basically I am thinking of just letting someone else take the entire thing out of my hands.

Edit: Them automated contract emails were saying how i joined a new contract then left it again when i reverted back.
