Notice for Ribble

Hi Ribble

Can you please check my parents - TF7 5PJ on Exchange CUCKOO OAK is served by Cabinet 9 as I think this cabinet is full as I notice my parents line sync rate has dropped to 42Meg from 80Meg.

Thanks.

i would not expect a full cab to reduce link speed from 80 down to 43 (you must be extremely close to it to get 80mb before)

maybe a fault maybe (do you hear any noise on the phone line when in call or when silent)

It's not my line. It's my parents line. There is no noise or cracking noise on their line. Possible crosstalk on their cabinet.

The cabinet is not full. That speed drop is too severe to be crosstalk.

The cabinet is not full

Not even close

Large Huawei passing 418 premises in a Virgin Media area. Would be pretty impressive if 288 ports were full

Then I don't know why is my parents FTTC drop from 79999 to 45878 as the upstream also drop from 19999 to 18766 as their SNR on both down and up are 6.0 dB but G.INP was enabled at 8:1

The phone line was fine as Plusnet supplier say my parents cannot get more 45 Meg according to BT. But BT Wholesale Checker say below:

Done anything like restart the modem/router ?

I did power down for 30 minutes and turn back on. Still the same!

Connected to the test socket?

If so, an engineer visit is required.

well in trials a speed drop of 40% is within range of expected crosstalk, if the line was only just about syncing at 80mbit then the loss of speed is over 40% but still under 50%.

Regardless they should report it as that should fail the GEA test with such a big chunk lost.

The test socket result was the same speed at 43 Meg couldn't get faster than that!

Speed now dropped to 26Meg. My parents not happy about it.

Maybe log a fault with the provider in that case?

Hi,

Sorry for jumping on this thread but I wonder if you could help me out with a query similar to OP's?

We've been having a lot of trouble with congestion on VM (especially single-threaded downloads) and are strongly considering moving to FTTC but I was wondering if our cabinet is nearly full? Because if it's first-come, first-served, I'd obviously need to hasten things. We're very close to the cabinet though so I doubt crosstalk would be an issue.

Exchange is LVHUY, postcode L36 2NW, and cabinet P37. When I've seen the doors open it looked like about half of the fibre block was taken, from a distance, but best to check.

Many thanks!

considering how long it's been RFS I don't think it's going to fill up any time soon

Crosstalk isn't really a distance issue, I'm pretty close to cab but still lost 35meg due to crosstalk and still seeing reductions in sync now.

If the FTTC Cabinet is very close to your property I doubt any crosstalk will not reduced below 80Meg.

My FTTC went live in February 2014 and it now 25 months with 79999K/19999K still ongoing without reduced yet.

My latest line stats below:

Downstream Upstream
Line Coding (Trellis) On On
SNR Margin (dB) 12.3 15.9
Attenuation (dB) 11.1 0.0
Output Power (dBm) 12.5 -1.2
Attainable Rate (Kbps) 103805 35823
Rate (Kbps) 79999 19999

Thanks for the replies guys. I've seen a guy working on the cabinet quite a few mornings on my way to work recently so thought there might have been a sudden marketing push in the area or something.

The upper and lower non-impacted estimates are both 80Mb for my line.

I'm properly few up with virgin's woeful single thread speeds, especially around peak time. But because it's not a local node issue they're refusing to admit there's a problem, despite the fact a large number of people in the same area are impacted.

But that's a topic for another thread!

Just out of interest, is half full about right?

No probs if you'd rather not be specific though.

About half that

That's reassuring!

Cheers!

I was the same shoes as your too when I used to be with virgin media, getting fed up of 160Meg down to 35Meg every nights with high utilisation ongoing for 5 months then I quit virgin media to join plusnet FTTC from February 2014 and my FTTC never drop speed nothing like Virgin Media as the worse service unreliable. Virgin Media is the one to avoid it at any cost!

How do you find single-threaded download speed? Because that seems to be the main issue with me on Virgin - speedtest.net's massively multithreaded test is only occasionally affected but any single-threaded downloads like normal file downloads, Linux updates, etc are painfully slow.

This sort of thing is normal for me around peak time: http://www.thinkbroadband.com/speedtest/results.html...

FTTC can be very good but can also be bad.... the ISP you choose is very important.

The infrastructure itself is fine but ISP's have seemed to struggle over the past 6-12 months with capacity on back haul & at data centers..

I started my FTTC experience with Plusnet... that was a bad hoice, speeds went bad, packet loss and to cap it off a lack of customer service which didn't help the matter... I had to involve an ombudsman in the end to get the contract killed off.

I believe things have got a little better at Plusnet but still some issues... I would avoid them for fiber 'currently'

I then switched to Zen (through their own network not BT's) that was great but after a couple of months they too started having issues on their back haul which I believe are still ongoing... I left them too...

Currently I've been with BT for 3 months and that's been pretty good.... (better than I expected)... Had a couple of issues with there Hub 5 and customer service isn't too great but with my own router and using my old Openreach branded modem it seems to work very well, I have done many speed tests during the time with them and only witnessed any single thread speed reductions 2/3 times and that was only losing 20-30 meg and wasn't consistent... so wasn't the same in the next test.

The only other provider I would consider right now for FTTC would be Sky... however their Terms and Conditions don't allow use of 3rd party routers and their current hub is a bit entry level, it's possible to use your own router but I 'think' their is special requirement's and can be tricky to set up.

I would avoid Sky! As my mate used to be with Sky and always had problem with them. They doesn't seem care to get it fix, all they care is money!

As for Plusnet, things are getting better and better now.

Pretty nightmare to be honest! Downloading is awful throttled! Only getting between 500kbps and 1.8Mb/s compared to my Plusnet FTTC is downloading of 8.8Mb/s at all times.

Err. NO.... Virgin don't throttle any downloading.... Plusnet do however!

Plusnet do not throttle! The downloading speed will be drop if someone watching any movies online eg: netflix or skygo as plusnet put streaming priority over downloading. But, if no one use streaming, then the download speed will be maximum on line speed rate all day.

I don't remember ever seeing multiple forum threads regarding this...

My experiences of Sky have been the opposite of this... Sky seems to have a much more stable connection compared to other providers... That's across 3 connections on three different exchanges and lines...

As for Plusnet, I'm sure things are getting better, however how would you know, you've always said Plusnet's been rock solid for you.... are you telling porkies???

it's also a shame this guy don't seem to be part of this "Getting Better" you speak of

This is because of Plusnet limit his line capped to ADSL2+ not VDSL, as the current line speed should be set at 78Mb not 21Mb. It's just a slightly mistaken by PN 's end. It's shouldn't has happen in the first place!

In reply to a post by adslmax:

That isn't what Plusnet say:

In reference to www.plus.net/help/broadband/about-traffic-prioritisation/:

we would prioritise traffic on our network

However Virgin say:

In reference to my.virginmedia.com/traffic-management/traffic-management-policy-30M...:

you can download as much as you like without worrying about traffic management slowing you down.

and there you go then, I rest my case...

Plusnet limiting line capability...

To be fair, since FTTC activated in Feb 2014, I never seen any slow down in my downoading speed always at 8.8Mb/s all day, all night. So, what is the seem problem?

Edited by adslmax (Sun 27-Mar-16 13:27:20)

To be fair I have 2 Virgin connections ( 3 until December when I moved out of Virgin area) they all max/ed out without any issues too.... sooooo???

Also I thought your connection synced at max rate???

I think Plusnet's stealing 5Mbit/s from you, you should be getting around 9.3MB/s based on 74.8Mb/s but from your 8.8MB/s your only getting 70.4Mb/s

Also cheers for your message:

When my Plusnet contract is ended soon, then I will switch my FTTC to Sky Fibre Pro because I do have excellent bargain with full bundles sky tv with family/sports/movies and HD pack with multiscreen at 75% off for 12 months with 2 boxes of 2TB Sky+ HD boxes.

I believed that Sky want to change Sky UFO Fiber in all areas soon. Sky had enough with BT Wholesale and BT Openreach. https://www.ultrafibreoptic.co.uk/

But why would you want to switch to Sky... they're terrible aren't they???

The message should be PRIVATE sole only. I can't be arsed bother talk to u anymore. Bye

Yes, But I think it's wrong to discourage somebody from a provider and seemingly encourage them to join a provider with a rather distasteful 'recent' history when your happy enough to move to that provider even after suggesting they should be avoided.

Traffic prioritisation/QoS != throttling, they're very different concepts. Plusnet don't, to my knowledge, arbitrarily throttle traffic a la Virgin's old 'we'll kill your speed after x megabytes' policy, which does still apply on the upstream.

Provided a network has sufficient capacity to avoid regular degradation of service, QoS is a perfectly sane thing to use; if e.g. a transit link hits saturation, it's not going to ruin anyone's day to see a small reduction in torrent download speed, whereas completely dumb traffic handling could likely see things like streaming, gaming, VoIP, etc getting severely impacted.

That's exactly what Plusnet describe - they're not just limiting download speed for the fun of it, rather they will try to give critical packets priority to avoid serious problems. Again, provided they have sufficient capacity to ensure they're not regularly hitting saturation on links, I don't really understand why anyone would have an issue with that. It would also surprise me if other large networks don't do this to an extent - it seems almost careless not to. Plusnet are just open about it, but I think people see 'traffic management' and associate it with the arbitrary throttling we've seen from the likes of VM. It really isn't the same though, and I even use QoS on my own router to ensure things like file uploads don't kill real-time applications/streaming. It's not doing any harm in the background, but it simply lets everything work a bit more harmoniously when the link gets maxed.

Although TBH I'd even take VM's arbitrary throttling over the issues I've been having lately. I've just been struggling to hit 2Mbit/s on some Linux updates...

Edit: Nice! http://www.thinkbroadband.com/speedtest/results.html...

Edited by deleted (Sun 27-Mar-16 22:25:52)

Yes, I'm fully aware of the systems that Plusnet have in place with regards to QOS... It was one of the reasons I originally signed up to them, however it never seemed to work too well, I always had streaming problems.... on Radio of all things too...

Virgin's system they use on the upstream should probably of never been removed from downstream, they should of just increased the allowances, it would certainly reduce the issues such as ones described in this thread.

streaming never had any problem with plusnet over the years!

I thought you wasn't talking to me anymore.....

Also don't remember saying you did...
