When congestion is given as a reason for speed drops, how much is acceptable?

[#1]

@jelv For £200 pa I can tell the rest of the household to do one

Surely there's a way for the line throughput to be interrogated from the other end too?

Yes there is! https://aa.net.uk/kb-broadband-cqm.html

@DocDelete Whilst I do appreciate the frustration, should initial checks on the VLAN not find any issues, our suppliers really do need to see the BTW speedtester fail when you complete the further diagnostics as it helps their investigations.

Keep me posted please.

Hi @Gandalf just done the test, and the further best effort test using BT's own connection.

I struck when I noted throughput drop below 10Mbps. It's now sitting at 4Mbps.

During part 1 of the BTw test it was around 8Mbps, and during part 2 it actually dropped too low to read 0Mbps!!

We should note that BTw place a low threshold of acceptability at 20Mbps - if only.

Screengrabs...

Cheers for doing that @DocDelete

Was the second part of the test run with the username in your router changed to speedtest@speedtest_domain?

[#6]

@Gandalf yes (I've done this test sequence a few times in the last year)

[#7]

Cheers for confirming. I'd like to take this result to our suppliers.

Don't run the further diagnostics again please as it'll override the previous result.

[#8]

@Gandalf Thanks, and don't worry - hands off!

[#9]

Awesomeo and just to confirm something else you're using a wired connection right?

[#10]

@Gandalf all tests I've ever displayed here are from my laptop directly jacked into the router via ethernet cable.

[#11]

I'm about to speak to QA.

I'll post back when I've finished.

[#12]

Our suppliers are investigating and we should know more by Monday.

Our faults team will follow up when we've got more info.

[#13]

@Gandalf i have more info. Saturday night saw throughput drop to 1.5Mbps. Tonight (Sunday) it is currently around 0.5Mbps!!!!

Ping is coming up at around 450ms, with plenty of dropped packets. I first noticed this when I couldn't even get browser pages to properly complete CSS formatting. YouTube? Forget it.

Unbelievable and unacceptable. 

I'm going to disconnect and reconnect the router in the vain hope that it'll tell the service that I'm still alive.

The next step will be to request that Plusnet refund me in some way for a poor service. Then wait until my line rental saver expires and move to Virgin.

[#14]

Graphic version of poor speeds. You can clearly see last night's prolongued 'bumping along the bottom' and today the throughput started dropping off at an unbelievable 6am!!!

Today, much rests on the noises made by Plusnet in regard to this situation.

[#15]

Latest graphic. I'm posting this because I simply can't believe how poor and repetitive this service is. It's worse than when a hot VLAN was (eventually) diagnosed last time, so few weeks ago.

@Gandalf I believe under the circumstances that Plusnet owes me some proper communication. Please instigate a full problem ticket from your end. I want you to do this because I absolutely need to avoid covering old ground again and again. The new ticket needs to start from this point, and pick up a solution from BTw. When will you do this?
