Just activated - speed fluctuations.

Hi All,

Had my line activated today and having big fluctuations in speed each time i test 40-60

Is my line going through the "Training period" ..how long before its stable?

Plusnet website reports:

Estimated line speed:
64Mb (Accurate to within +/- 1Mbit) - Checked on 2013-05-21 12:34:02
Current line speed:
78 Mb

Profile from http://speedtest.btwholesale.com/

Download speedachieved during the test was - 44.74 Mbps
For your connection, the acceptable range of speedsis 16 Mbps-77.44 Mbps .
Additional Information:
IP Profile for your line is - 77.44 Mbps

---------

Upload speed achieved during the test was - 16.45Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

Try downloading a test file and watch to see if your getting a consistant stream of data or not, Tbb test files

There is no 10 day training period with FTTC You start with the highest Sync that your line is capable of and it goes from there , Most lines start off stable, Have you used the speedtester on this site? As it seems to be popular

On FTTC, the line doesn't really undergo "training" in the same way as for ADSL lines.

Those test results show a downstream IP profile of 77.4Mbps, which means you are syncing at a full speed of 80Mbps.

DLM will now be monitoring your line, to decide if it working at a high-enough quality level. Unless it sees a lot of resyncs (which you'll be able to see yourself) or a very high number of errors (which you can't see), then it won't do anything at all for the next 2 days. At that point, it might choose to add interleaving & error correction - if it has seen some errors on the line.

So, for now...

Plusnet's system records a matching speed - which means they aren't limiting your speed.

You should be able to run speedtests, and get results around 73-74Mbps. Have you tried speedtest.net yet? Choosing one of the London-based servers (though I always find Vodafone in Newbury gives good results).

And are you using a wired connection, or wireless, to the router?

On my new connection, the speed goes up and down like a yo yo. I'm not worried about the lower speeds as they don't remian low.

Chaps,

Ive tried a few more tests and looks better.

Speedtest.net - Newbury - (55/16) http://www.speedtest.net/result/2743352841.png

Speedtest.net - London, Ealing - (72/18) http://www.speedtest.net/result/2743357375.png

Speedtest.net - London, Vodafone - (53/16) http://www.speedtest.net/result/2743362772.png

7 to 8.7MB/s on TBB 1Gb test file.

Some other questions please:

Do you guys also get a 20Mbps odd difference between speednet servers like the above?

TG582n is the SuperUser password the serial number? (tried and not working)

cheers

Do you notice the Yo-yo speeds in day to day usage? do you do any online gaming?

My fibre took a day to settle at the speed it is now.

As far as I'm aware there's no SuperUser on the units we ship. The admin username and password should be detailed on the router or the card that came with it.

Getting different speeds from different ookla servers is to be expected as not all of them are on gig or 10G backhaul links.

Should give you graphs you can link to and show how stable or variable the speeds are

Ahh ok thanks - I thought it might be required to enable ping responses, but can see this is available in the GUI.

SuperUser was just a trick in the O2 router firmware to stop "Administrator/admin" level users being able to alter anything important. I haven't come across it anywhere else.

I play WoT and the servers are getting an average 15ms to 30 ms checked by PinPlotterFree

more likely congestion than anything to do with the line.

congestion where, cant say.

If speeds are consistently fast between 3am and midday almost certianly congestion related.

The most closest to off peak tests you did were the after midnight, 2pm ones and they were fast.

Do you notice the Yo-yo speeds in day to day usage? do you do any online gaming?

Some of those speed drops of blfamily's suggest something funny is going on there - you shouldn't be seeing drops to 20Mbps on the unlimited, 80/20 package (which I guess you are on) unless something else is using the connection at the time of the test.

I'm on the Extra Fibre package (haven't got around to changing to unlimited yet), with 80/20 sync speeds.

I have a SamKnows test box monitoring the line, so I have a good idea of what congestion is being seen. That box tests the download speed hourly at peak times of day, and at a few other select times - and is fairly clever in trying to run tests when nothing else is going on on the line.

Here are the average speeds it found during the complete month of May:

Time      Average (Mbps)
04:00     72.84
10:00     72.46
16:00     71.56
18:00     71.29
19:00     70.56
20:00     67.57
21:00     72.17
22:00     72.07
23:00     72.59

And here are the actual speeds for the 28th-31st May:

23:00     72.6     72.8     72.2     72.9     72.9

The only real dips are 8PM (almost always) and 9PM (sometimes).

I agree. Last night was the same, a distinct drop in speed at 8.45 that got even worse betweeen 9 & 10.30pm before recovering just after 11pm. I looked at some ping tests and these were not conclusiive, today have changed DNS to see if that makes any difference.

Hopefully I can get the BBQM working on a dynamic IP. Will see if that shows anything a miss.

PlusNet dynamic IP address is quite volatile! I advise a simple one-off £5 through your Member Centre for a static IP. It's a far better idea . Takes effect immediately, applicable on reconnection.

I've seen occasional reference to f8lure that seems to do a similar job to the BQM (also using Firebrick).

I've not tried them, but they apparently do DDNS, if you don't mind using a DDNS agent in either router or PC.

I'd go with the £5 option though...

Another thought on this...

Sometimes the issue is that one of the Plusnet gateways can get unbalanced and overloaded - causing this kind of issue.

If that *is* the cause, then hopping to a new gateway can solve it - which can be done by starting a new PPPoE session - so reconnect at the router (not modem) or just reboot it.

To see what gateway you are on, use the PN Usertools Gateway Checker.

To see what the various statistics say, look at the PN Network Performance and the PN Network Latencies, which display some information for each gateway.

One of the things I was concerned about before joining was the latency for gaming, I can now confirm all is well so far. My latency in gaming dropped by 10ms in fact.

As I was comparing graphs in the BQM thread thought id share my Plusnet graph:

O2 (30/05/13)
http://www.thinkbroadband.com/ping/share/f6b9520024c...

Plusnet (01/06/13)
http://www.thinkbroadband.com/ping/share/a73c209be17...

Success? I'm Happy.

That's an extraordinarily low latency. Wow

Does the admin username for Plusnet routers allow one to get full stats, like the SuperUser name does for o2? And for using RouterStats?

Edited by rob54 (Sun 02-Jun-13 20:02:37)

As installed, you cannot get line stats on FTTC, unless you are with Sky and apparently also TalkTalk.

That's because line stats exist within the modem, or the modem component of a modem/router such as the O2 box. "Cable" routers such as are used on FTTC do not have access to them.

Sky (and TT?) have access to them at their end and seemingly echo them back to their supplied routers.

If you have an HG612 modem that is easy to hack and get all sorts of useful stuff. If you have an ECI one hacking that is less easy.

I suppose this thread is about fibre but I guess I was thinking does the admin username give you stats for ADSL PlusNet

I believe so. As I said, the O2 setup was their own special, to hide things from admin. A stupid PITA!

Just to add: I ordered the 30m extension kit on sign up. (To plug the BT modem in a different room)

The BTO chap informed me they don't do that and if I want an extension socket there its £100.

I wouldn't hold my breath on this part of the service!

That's a badly-misinformed BTO chap then.

It seems that the fact an extension kit has been ordered gets lost on occasion. But I don't think I've seen a BTO guy not know about it at all before. Contractors, yes, but Openreach staff, no.
