Broadband Speed dropping

I have been having problems with my Broadband connection with (Surprise,surprise!) TalkTalk.
In January I was getting a, for them, breakneck download speed of 1.96Mbps.
Since then my IP address keeps being changed and almost every time the download speed has dropped.
Today it had got to 1.0Mbps and I finally decided to call their Customer Service to report the fault. A very brave thing to do!
To cut a long story short they informed me that my line could only handle a speed of 1.2Mbps and, since 1.0Mbps was only 20% less than that speed there is no fault. When they then asked me to hold on, I said I would as long as the fault was going to be fixed.
At that the line went dead and my blood pressure rose!
I have tried to discover why my IP addres keeps changing and why this should affect the download speeds but "answer came there none".
As far as I can discover all Broadband suppliers have an Overseas Call Centre where all queries are responded to by using a checklist of questions without any knowlege of IT.
Any easy answer would be welcome but I do find that a lot of your Forum responders talk in a technical language which I do not understand.

If you can get us the statistics from the router that would be great.

If you need help doing this let us know which router you have.

IP Address changing is a side effect of the ADSL disconnecting and reconnecting and the dynamic nature of the IP addresses on TalkTalk

What is the model of router you have from TalkTalk, we can then guide you to a page with some router statistics on it, and then if you paste them into a post we can advise more about the stability of the ADSL line.

The suggestion currently is probably that the ADSL is unstable, and a good chance that would be the same no matter which provider you are with.

I am using a Belkin Router, not a TalkTalk one.
The model is a Belkin F7D11401v1.
It is connected by cable to my PC.
Am I to suppose that the ADSL line problem is not fixable or needs a Broadband Engineer to be sent by TalkTalk? They do not like to pay for that service!

There is a good possibility the issue is with your wiring in the home, which you or any competent telephone engineer would be able to fix

Will go find out where the router stats are hidden first

Start by showing us your current line statistics.

start/run/ cmd should open a black screen on your monitor. Type ipconfig in this box, and hit enter. The results shown will include 'default gateway' which will show the IP address of the router 192.168.1.1 for instance.

Type this in your browser and it should open the web based interface for the router ...

Belkin F7D11401v1 does not show up on Belkin webpages, other than three Italian pages.

But there is a F7D1401_v1

In your web browser type http://router into the URL address bar
If that does not work try http://192.168.2.1

And then you need to goto

http://router/status.stm
http://192.168.2.1/status.stm

I think, cannot be sure as there is very little useful documentation that I could find on the router.

Actually no. But it comes down to cost. Everyone wants a cheap service and the only way to keep costs down is to use centres of cheap labour for call centres.

Choose your ISP and pay a little more and you will find much better customer service.

Try from the Belkins here: http://www.kitz.co.uk/adsl/frogstats.php#3

what does the Talk Talk speedtester say ?

http://myaccount.talktalk.co.uk/speed-checker/check

the result at http://myaccount.talktalk.co.uk/speed-checker/check/... shows a speed at the router which is the sync speed to the exchange, then the speed at your PC which is a speed test result. How do they compare.

I do not use a TalkTalk Router. I use a Belkin F7D1401v1 Router.

Thanks but what will this site do?

I thought we were discussing getting your router stats, w/out which we cannot really advise.

Does this help?

I have posted some of the router stats.
I know that, last year, there was a problem on the line which was fixed.
It also appears that, due to the cost, TT are very reluctant to call in a Broadband Engineer.
Strangely, on the last visits from Broadband Engineers they told me;
a: the line's maximum download speed is 1.4 Mbps
b: the lines maximum download speed is 1.2 Mbps.
Without doing anything the spedd went up to 1.66 Mpbs.
Does "Mpbs" stand for " Mighty pile of Bull S***"?

It shows a long line (>=63 dB attenuation) achieving what may be a respectable sync speed for the 9 dB default noise margin.

Do you have a feel for the distance from the exchange ?

Edited by yarwell (Thu 07-Mar-13 12:02:07)

Removed a few bits that may ID your connection in your post

Yes

It tells us that you are probably on a phone line that is longer than 6km long, i.e. you are a long way from the telephone exchange.

The higher speeds previously were down to you having a 6dB target noise margin I suspect and some instability has resulted in this been raised. If you join the TalkTalk Members forums and read their FAQ posts, you can then post the information and possibly request a change of profile to get the 9dB target margin dropped to a 6dB one, and gain a few hundred kilo bits per second of speed back.

By the way, switching provider to another one is not going to help really, and could result in your going even slower.

Try the BBC iPlayer diagnostic speed test - I find it pretty good, and also as the BEEB have a fast pipe (or lots of them), you will get a 'truer' estimate (plus it does 4 tests of some sort):

Nick

Thank you!

BBC give 1.44 Mbps too!
The problem is the changing of speeds with a change of IP address.

Thanks for providing the link for the iPlayer Tester.
Totally unable to find anything about on the BBC iPlayer site!!

It is the reconnection of the router that is causing the IP address to change.

You have such a long telephone line that the ADSL is likely to be less stable, and when its unstable the router will sometimes lose the connection, i.e. the noise swamps the ADSL signal and it will disconnect and reconnect when this happens. The reconnection means your router asks TalkTalk for an IP address and as you have not purchased a static IP address service it very likely will change.

The only way your IP will change is by a disconnection and resync. Do you turn the router/modem off (over night, say), or keep rebooting it? Or does it disconnect/reconnect by itself?

Nick

BTW, if you can, change the mode the router sync's at to just ADSL (not ADSL2/ADSL2+) - it might appear as itu.G.DMT etc.

You have a long line. ADSL might be a bit more stable on that than ADSL2/+

Nick

Edited by deleted (Thu 07-Mar-13 14:59:09)

Thanks, I might give that a go!

Yes I am a "long way" from the exchange.
I tried to tell the engineers that there is a telephone line from the West Coast of Scotland to America and it does not appear to have a problem with distance!!

I leave the router on overnight and TT change the IP Address themselves!
Sometimes I switch off the router myself and try to get a better speed that way when I turn it back on.

How do you know its TT changing it, and not the router dropping the ADSL connection to reconnect?

The honest answer is that I don't know.
I leave the router on all the time and, some mornings when I open up my emails, the connection has been changed.
I leave the PC on with my mail open.

Router works independently of PC.

The IP is changing when the router re-syncs due to a discon. It should not make any diff to you.

So, somewheer a disconnection is being made, but not by me?

The difference is that the speed usually drops when it changes. That is why I suspect TT to be involved somehow.

The line is long and unstable. it simply discons when it can't sync anymore. It's your line; not TT doing anything.

Have you tried test socket? Tried diff filters? Removed ring wire? What extensions have you?

Did you try changing router's Mode to ADSL (G.DMT) as suggested? That taxes the line less.

I'm with AOL and had similar problems and I think the same router ('n' with 2 USB ports?).
The router was flaky from day one but I got round the difficulty.
In November I had a fault on the line.
In January I still had as fault on the the line etc. etc.

I changed routers and even bought a new ASUS - still all over the place.
After Christmas, I got really fed up and after a lot of threats -
BT OR engineer 1 turns up out of the blue just we were going to the vet. Back in about an hour, we cheerily said . Less than an hour later no BT man and no telephone service.
Then another BT man turns up to fix the phone. We have a cable fault 6 meters away from the socket! Nuffin to do with last BT guy!!
Re-route cable via a spare pair to box at bottom of road. You need a broadband specialist, he says.
Another BT man comes, changes socket and can find the sync at over 9m. Goes to connect to internet and finds he can't. Then apparently I was using another connection 0 which died when he pulled the plug out!
Off to exchange and rings me up to say still working down there, but AOL won't talk to him.
This Monday I'd have enough and rang to find out if they had cured the fault. Closed at the beginning of February they said and anyway you are getting the maximum available on your line (by this time I'm syncing at about 5m). For some reason I am lying and their data is spot on. I get asked if I want to speak to a manager and I just said if that's all I can get, what's the point? Manager comes on, speed test done, conversation goes along the sorry saga and then I am asked to do another speed test. Funny, but it's now over 9meg. Re-profiling done.
Why does it take 4 months of going round in circles?
This afternoon Talk Talk rang to ask if everything was OK. I did express my concerns about the time and effort by everyones when I suspect not a lot was wrong that a large club hammer wouldn't fix (preferably in India!)
I'm sure it would be cheaper and better for their business if only..............................

Have an ADSL box on the line coming into the house.
There is an long lead from this box to the Router and the Router is connected by cable to the PC.
Ring wire is a mystery to me.
There is a phone plugged onto the box with an extension to an upstairs phone.

No, I may pluck up courage tomorrow for that!

"ADSL Box" = Socket with filtered faceplate?

In reply to a post by scottie4642:

Better to shorten the modem lead from the socket and lengthen the Ethernet cable to the PC.

Removing the Ring Wire

Is upstairs phone filtered?

...There is a phone plugged onto the box with an extension to an upstairs phone.

Is the extension wired to the inside of the "ADSL box" (i.e. to the back of a NTE5 filtered faceplate) ?

The extension is plugged into the socket for rthe Router Cable which is the other socket on the box.

Does that mean that you have 2 phones connected, via a splitter, to the front of the box: i.e. a phone downstairs and another phone upstairs on the extension?

OK, I dunno what you are trying to say there, but if you can just try this.

Turn off router. Unplug all the wires (all wires, including phone). Then just plug in the cable from the router to the faceplate. So you have:

|router|<------>|faceplate|

Turn the router on. Wait 2 minutes.

Then test for 30/40 minutes.

Not clear!

Are you trying to say that the router cable is plugged into the ADSL socket of the filtered faceplate and the extension to the upstairs phone is plugged into its Phone socket?

Remove the phone extension from it and retest.

That is exactly the situation.
The "phone socket" has a 2 socket part plugged into it. 1 of the sockets is for my phone downstairs and the other goes to the phone beside my PC, upstairs.
Does this complicate matters?

If this is the answer then I would need to just stop using the phone, permanently.
Seems a bit of a palaver to me.

it's called diagnostics. You make a change and see what effect it has. From that we learn. Otherwise you're wasting everyone's time.

so the master socket has two different sized sockets on it ? or two sockets the same type ? A photo might save some of the guesswork.

The Master socket has 2 "sockets". The Left Hand one is the connection for a router, the Right Hand one is a normal, shuttered, phone socket.
To allow me to use a phone upstairs, where I have to keep the PC, I require an "2 extension plug" which goes into the Phone Socket. From this I run my downstairs and upstairs phones.
Does this help?

Sorry Yarwell, I am not trying to waste anyone's time!
I just find that, to get a poor quality speed to my PC, seems to be more than there may be a fault on the line.
My problem is that, without me doing anything, my download speeds drop.
If it was something in my house connections that was causing the problem I would expect that nothing would change.
When the Professionals come up with different available, maximum, speeds for the line, I find it very mystifying.

>When the Professionals come up with different available, maximum, speeds for the line, I find it very mystifying.

That line is odd to me, what different speeds. Everyone here has been in agreement on your line speeds.

The joy of ADSL is that it is AM radio crammed down a telephone wire, and the pops and crackles you would get listening to an AM radio station can also affect ADSL. When these happen the modem loses the signal and drops the connection to retune, and sometimes after the retune it does not get quite as good a signal.

So the master socket looks like one of the sockets in this picture.
http://www.thinkbroadband.com/images/iplate/bt-adsl-...

If so then these can break occassionaly and so removing the faceplate to reveal the test socket and checking there is to be advised. i.e. http://www.thinkbroadband.com/images/faq/faceplates/...

Probably make no difference, but it is part of work someone would do if you paid them to come out and look into things for you.

I meant the "Open Reach" Engineers.
One said that the maximum speed that the line could deliver was 1.2Mbps.
Another said that the maximum speed the line could deliver was 1.4Mbps.
Immediately afterwards my speed shot up to 1.6Mbps!

On a previous occasion, after several engineers tried to fix a fault, on engineer investigated the line, found a faulty connection, did a temporary fix, and the speed went up to 1.96Mbps.
It seems all smoke and mirrors to me!

'Openreach' engineers are generally not trained in how to estimate speeds based on the mathematics of how ADSL works.

Some some will be finger in the air guesses, others based on some automated systems and even with the best mathematics the variation in noise environments can give different results from day to day.

You are on a line that is so long, that a few years ago you would not have been allowed to order ADSL at all and in some cases where people complain a lot, Openreach has given people the choice of take this level of service or just cancel.

Sounds like a "Heads, you win! Tails, I lose!" situation!
I do, however, appreciate the suport from the Forum.

No, as others have explained, if you just test with the router *only* connected, and there is no change, then you know it is not the phone wiring that is at issue.

If the connection IMPROVES with only the router connected, then you know you have an issue with the phone side of things, and can start to look at the phone extension cables/filters etc.

Nick

Did as you suggested, thanks.
Before disconnecting the phone:
Download 1.37 Mbps Upload 0.55 Mbps
After the disconnect:
Download 135 Mbps Upkoad 0.56 Mnps.
I will now re-connect my phone.
Heigh Ho!

Does this help?

So you have a splitter ("2 extension plug") for the phones and a long ADSL rj11 lead for the router connected to the front of the faceplate?

Just for testing you need to remove the faceplate (which will disconnect both phones and the filtered faceplate its self) use a short ADSL rj11 lead together with a dangle micro filter, or a short modem lead, connecting the test socket in the master NTE5 to the router. This will probably involve bringing the router downstairs and using a long ethernet rj45 lead to the computer, or bringing both the router and the computer downstairs if you don't have a long ethernet lead.

Edit: if you have wireless connectivity between the router and the computer that would be sufficient for checking the router stats rather than using a long ethernet lead.

You need to report back the router stats as you did here: http://forums.thinkbroadband.com/general/t/4218209-r... . The router stats are all-important at this stage of the investigation; we will deal with the throughput later.

You are not helping us help you

Sounds like we are entering the World of the IT Masters!
I feel that I just have to acccept that modern technology has not yet reached my home.
I don't suppose I should consider 4G either!!

If the long ADSL cable or the filtered faceplate are not giving you optimal BB performance that would influence the loop loss (attenuation), downstream sync and throughput (download speed.)

I have a 3 metre ADSL rj11 CAT5 cable but wouldn't want to use anything longer and my filtered faceplate (extension wired to the back and phone connected to the front) gives me slightly better performance than any of the limited number of dangle filters that I've used.

It's possible that your phone extension connected to the front of the faceplate, via a splitter, together with the downstairs phone lead, and indeed the filtered faceplate its self, are also causing issues - that's if I'm picturing your setup correctly...

The box is a BT ADSL Box. This was because it split the Router Socket from the Phone Socket.
i.e.a Micro Filter is not required.
Because I require a phone upstairs I have a 2 socket plugin to the Phone Socket on the BT Box.
While I can understand most of the tech. stuff, I still do not understand why my Download speed drops without me doing anything to my system.

Because when ADSL encounters noise it disconnects and reconnects to negotiate a new connection. If the noise burst is still going on when it is reconnecting then you get a slower connection speed.

ADSL is prone to interference from any device that can produce radio frequency noise in the sub 1 MHz radio band.

This new connection means a request to your ISP to say please connect me to the internet too.

Fixed speed options do exist, but as this would mean for long lines there might be times where you are without a connection for hours at a time, the adaptive system you are experiencing exists.

Thanks!
It must be nice to live in the great outside World and not 2 miles in the country!
There is a rumour that Fibre to the nearest street Box is due sometime.
Even Freeserve is terrible here, limited number of programmes. Digital Radio appears to shut down at night.

I would get the extension wired to the back of the filtered faceplate, still connect the downstairs phone to the front of the faceplate, possibly even get a new filtered faceplate (pressac are pretty good), position the router near the master NTE5/filtered faceplate using a short good quality ADSL cable and use a long ethernet cable (or make up a LAN using CAT5 cable etc.) from the router to the computer.

You are apparently on a long line to the exchange so really home wiring needs to be as near perfect as possible...

Thanks for the help.
I will consider that option.

I live in the most populous city in the world outside the metropolis - Portsmouth. I live maybe 1 mile from the exchange. I cannot get adsl2+ as my line is [censored] now (it never used to be), so I am stuck on 6mbs or so connection (others around me get >9mbs) with disconnects once every 24 hours.

As to freeview, I get a really good signal (after buying a new aerial for wifey), even HDTV is brilliant (apart from all the [censored] programmes on it) - until a taxi drives by in the road. And living in a city, that is about 20 taxis an hour

Plus I cannot see the stars/galaxies any more due to light pollution (mars, venus, jupiter OK in binoc's).

So I would LOVE to have a 1.3mbs internet connection, no [censored] on the TV, and to be able to use a telescope to explore the universe.

You are lucky really

Nick

Nick,

I agree, the peace and quiet make up for a lot. Also the stars at night are wonderful too.

Although we are about 1/4 mile from a dual carriageway, due to our situation we very seldom hear any traffic noise.

The loudest noise is when the RN Rescue Sea King Helicopter flies overhead on its wayfrom the nearby airport (Which we seldom hear any noise from either) to a task.

There is very little traffic on our Private Road which leads to the Angling Club.

Also,there is a micro climate which means we get a lot of dry days and many with sunshine while the rest of the country is gettin cold and wet.

I think I will stay here!

Got fed up again with the speed of my download!
Unplugged the Router, waited 30 secs and reconnected it.
Speed had dropped even further to 1.35 Mbps from IP 91.18.162.154
I then repeated the procedure and, lo and behold!
Speed now 1.62 Mbps from IP 82.18.164.154
Magic!!!???

And did you bother to look at the connection statistics from the router?

As we have said it is not uncommon for an IP address to change when you reconnect an ADSL modem

There's no correlation!

Are these speedtests or router sync speeds?

OP just don't listen!

All I looked at and record in my Profile on the Think Broadband site are the speeds of the download and upload, also the IP address that gave these speeds.
What are the connection speeds you mention?

These are the Speed Test results from Think Broadband's Tester.
I accept that the only "correlation" is the difference in speeds which also seems to go along with a change in the IP address.
I now accept that there is nothing that can be done due to my remoteness from an exchange, 2miles as the crow flies and under 6 miles of meandering copper cable.
I will just have to put up with it!

Connection speed, sync speed, the speed the ADSL modem is showing in its web pages, that figure is what governs every other figure.

Usually on same page as attenuation and noise margin figures.

I am glad that I read "Computer Active"!
"sync speed,speed of ADSL Modem showing in its web pages". "attenuation and noise margin figures" All Greek to me I'm afraid!
We "Silver Surfers" just bumble along and, mistakenly, expect that we will get proper service from any supplier we use!

OK, we could be getting somewhere. I think that you always sync around the same rate but depending on what IP you get at each resync (when the modem disconnects etc.) your ROUTE changes. The slow IP (91.*

So this isn't about *DSL connection speed, it is about the dynamic IP you assigned!

I don't know if there is a way to ensure you always get the UK IP route - maybe someone else here has a few ideas!

Edited by deleted (Sat 09-Mar-13 07:41:10)

Actually, let me explain that in laymans terms:

1) You have a long line, so as MrSaffron says, you can only expect a certain sync speed - which you get consistently. Also it explains the disconnects, as the quality is poor

2) Normally, the difference between 1.3mbs and 1.6 mbs would be unnoticeable.

3) BUT, if you get the *slow* IP you route to Germany and whatever. The speed is the same, it just is slower as the path is longer - example:

Suppose you drove to London at 60mph, the quickest route. Say it takes 6 hours. But what happens if you drive to London at 60mph but go to Bath, then to Dover, then up to London. That would take maybe 18 hours, but you are STILL going the same speed!

So really your speed isn't the issue here, but the route you get when connected.

Nick

I find the Techical knoledge on here is mind boggling!
How you find out all this information is amazing!
I assume that the deal from TalkTalk is, if the connection is cut another IP address is found to make a new connecton.
I am accepting that there is not a lot can be done although I also feel that, somewhere on the line there is a small problem which needs to be fixed.
I am not hoding my breath for this to happen.

It's normal operation, no fault. I guess due to all the acquisitions and take-overs of the network companies, talktalk are part of several networks - including one in Germany. Of course, due to the 1000's of Customers, they must have several DHCP server banks (which allocate IP's). So sometimes you get the DHCP server in Germany and sometimes you get the UK NTL DHCP server. This all depends on what the network loading is at the time, I guess.

I have never had a DHCP *DSL connection, only a static IP, so have not messed with such, but I am wondering if you could put in a fixed *route* in your router settings... but I don't know. Maybe someone here on DHCP can help with that.

Nothing to do with Dhcp, a radius server in uk handles allocation and for redundancy talktalk will have several gateways so when you reconnect you may be on a physically different bit of network. This can happen even if you have a static ip.

I doubt they are routed via germany, just admin need to update the records for the old ip block.

As ipv4 blocks become more scarce look ups like this will become more confusing

It would explain why IP 91* is so slow (on data through-put) when the sync speeds are similar!

Nick

So would the more likely it is a different gateway hence different segment of their network

It looks like it routes via Germany to me.

Nick

Which hops are german?

If I could pick a "Fixed Route" I would wait until a good one popped up!
I believe that Talk Talk have a LLU at the exchange and that they can actually alter the performance on the connection. Something to do with "Spreading the load">

You have had a similar experience to mine with BT Engineers.
I kept getting Line Engineers who said the Telephone was working properly and Broadband was nothing to do with them.
It took a lot of hassle to get a Broadband Engineer.
At one point I wrote to the Director of Residential Broadband and the responce was quick and the problem sorted.
The next time I wrote, I was ignored!!

Correct! Sorry for the delayed reply.

I last one. I cut the trace as soon as it routed to DE.

That may have been somebody else - I've only been concerned about checking your line performance from the test socket and with your home wiring in this thread

Sorry I thought that I had replied on the Forum entry.

It was something linked to my post which had been entered by "northcall" re;"Xrayspex" "Limked"
Hope this clears it up.

Ah! normcall's post on Thu 07-Mar-13 20:54:30 - I'm with you now. Yes dealing with ISP's can be a hassle

In reply to a post by MrSaffron:

You sure? Are Radius servers involved in LLU? OP is on TT LLU; witness his up sync.

Well spotted! But I am doubtful of your conclusions.

1. Even if you route via abroad, this might increase the latency, but speeds around the Net are vast compared with the bottleneck that is your, and particularly the OP's, ADSL link. You can d/l stuff even from the States at full throughput speed of your connection.
2. What is TT doing dishing out IPs belonging to Deutsche Telekom & VM? Are they connected?
3. We don't know whether OP gets "a certain sync speed - which you get consistently". He has only ever posted 1 reading despite our pleas to post them every time he does a test.

No, the OP complained of 'slow speeds' - to us that means lag or slowness (I think). But there isn't much difference between 1.3mbs and 1.6mbs UNLESS you route the long route.

This is definitely the issue, I feel. If you sync'ed at say, 10mbs you maybe not notice it... but you sure will on a lowly connection.

Hence why the two IP ranges assigned are different. Re-read Scottie's original post, and it is stated WHEN the IP changes, the connection is *slower*.

Nick

EDIT: forgot to say, but where does it route to after Germany? Scottie could be doing a European tour before coming back to Blightly, for all we know.
