Big Drop in Speed....is it congestion?


[link to this post]
 
Can anyone come up with a theory?

Between 5.30pm and 11.30pm every single evening since Mid-August up until now I've seen performance like this on my ADSL2 connection, up until then everything was really fast, connected at a steady 12mbps and it flew.

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

It's really hard work to get any browsing, streaming or downloading done.

I've done every test to rule out my kit, master socket, different router, different laptops, done the BTW Speedtester (although can't it get it to test under Speedtest login) always comes back as busy.

The support team at plus.net have been supportive and helpful but the process to get anything escalated is like wading through treacle.

If it's any help I'm on the Beaconsfield exchange, here's my TBB speed test.

Would it be worth paying for a static IP and logging the connection using the BQM tool.

If you are sure there is no other traffic on the connection and the noise margin figures are sensible and stable then looks like congestion. Know any friends on exchange who will run comparative speed tests.

Might be just that exchange some examples from other tests on that exchange this month
A BT FTTC connection

if its congestion generally should be fine between midnight and breakfast time,

If you can get more people to do speed tests to increase data set it might reveal a pattern over time or a specific area e.g. massive RF problems from some dodgy electrical device.

Looks like congestion/contention to me, if it improves at quieter times then this would confirm it, Your ping on that speed test result is alarming 30++ms ???? Getting a static IP and setting up a Quality meter would only show issues with latency and jitter, but congested circuits do quiet often show packet loss and higher base latency coupled with jitter , as well as the issue with erratic / inconsistent levels in throughput , which will also cause latency issues known as buffer bloat because the throughput cannot sustain it's max

Thanks for the really informative posts and information.

It's got so bad, I couldn't actually call up the forum or do anything, I've had to move to an EE mobile broadband SIM which is motoring along.

I have to get up at 4am for work and run tests and it zips along at 11.6mbps and the line is syncing at 13.5 to 14mbps and I've done that most mornings.

Is there anything I can do? I'll check around for RF stuff but I've hardly got anything on in the house.

it could be like in my case a few years back with my new neighbor who brought back with him some dodgy electrical satellite stuff from overseas

I had to go out and about with a radio on the medium waveband trying to find out the cause

lucky for me he let me in and got it sorted via a large bin and no he was none to pleased i can tell you

More likely the Plusnet issue that has been going on since last December!

There's a number of us posting complaints about speed tonight the Community forums: http://community.plus.net/forum/index.php/topic,1408... (reply #615 onwards). This is a continuation topic - the previous one on this issue went to 2316 replies when it was locked.

Put simply there is an issue with the Plusnet set-up, whether it is on the BT network between the exchange and the Plusnet endpoints or internal to the Plusnet network we haven't a clue and quite frankly it appears Plusnet haven't a clue either.

Disconnecting and reconnecting to get on to a different gateway usually solves the issue (until you have a disconnection that puts you back on a bad endpoint) which tends to indicate it's not exchange contention (in any case people from all over the country see the same).

There's now quite a number of people who have managed to find a permanent solution - by migrating to a different ISP!

Here's my speedtest from earlier: http://www.thinkbroadband.com/speedtest/button/14429...

That's on a line syncing at 80/20 (capped at 40/20 by Plusnet) logging very, very few errors - the cabinet is about 40 meters away.

What browser are you running?

Just over an hour ago, just out of interest I ran a thinkbroadband speed test and got an OK x1 result and a poor x6. So I re-ran it. Same again. Then I realised I was using the Firefox browser, so swapped to IE. Perfect. (Note, this is on AAISP not Plusnet).

Result 1.
Result 2.
Result 3.

The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - AAISP Home::1 80/20. Sync 59999/14372kbps @ 600m. - BQM

I love the anecdote about the large binlid, my neighbours are pretty cool so I'll ask around.

I didn't see that ongoing thread, I'l check it out, thank you again one and all, great community.

I'm running the latest Chrome, I'll try out another browser later.

So just before I go to work here's another speedtest taken at 4,40am this morning.

Well it's got so stupidly slow in the evening, I've now given up on it and turned the router off.

I've tried hopping gateways and get the same results on every one, between 0.4mbps to 3.4mbps but everything is crawling. I can't even browse the internet.

Escalated it within Plus Net, and got a really friendly and patient guy who's sending an engineer out to check everything ... I'm hoping he finds something between here the exchange all my wiring this year was done by an ex-BT engineer who used to work in this area.

The only other thing they've found is a lot of disconnections (since they're big outage) which is unusual as it was stable before that, thanks for your help, I'll update you on Monday.

Mobile broadband with EE (at least that's fast) for now.

Given that your speeds are fine outside the peak period, sending an engineer is going to be a waste of everyone's time!
