normally both downloads are flat 52Mb/s

FTTC Infinity 2 not much better.

Mind you this is TalkTalk Business, and it's even worse

Mine was like that yesterday

I'm with Zen using BT's wbmc for backhaul and have been seeing this since zen migrated my service over to their GEA backhaul and then back to BT wbmc again, why has the GEA issue followed me, i didn't have this prior to Zen migrating my service
Big ss of speedtest result
Normal size result of same test
So we are getting ADSL2+ speeds or less with the single thread downloads BT will think this isn't a problem no doubt, there speedtester performance tester only tests throughput using multi-threaded so how are customers supposed to demonstrate this issue to BTW???????????????????????????
I have had this [censored] now for the past 3 weeks how much longer?

And suddenly everything is back as it should be:

Is this the TBB effect, I wonder?

I had that earlier today when I did a speed test, but mine was doing an IPv6 Speed Test, speedtest.net was fine with no issues, so I waited an hour or two and retried the TBB speed test and it was back to normal.

There is no point me doing a speed test atm due to congestion where I loose half my connection, but its still better than what I had on ADSL

No code changes here - flash is frozen in fact
No server rebooting
No alarms suggesting we are even getting close to bandwidth limits, plus have checked and nothing that the alarm monitoring missed

I knew it wasn't to be likely something your side because Zen's tester mirrored it to an extent for me , plus normal downloads using single thread where erratic and never max

There does seem to be an issue with either WIN7 or FF browser where by sometimes single thread will max at around 30mbps almost flatline , this is both testers But the issue was not present when using WIN XP PC running FF with the same extensions

I did my tests on Windows 7 pro and OSX latest.

I did min on COUGH Windows 10 Pro with Edge COUGH which is normally fine.

I've been getting the same issue in the last week on Talk Talk Fibre Large connection.

I resolved it by turning off the router for 30 mins to reset the connection, which actually gave me faster speeds than ever before.



It then ran fine for 3 days and the same problem occurred this morning and I also resolved it by turning off the router for 30 mins.

Talktalk have been no help in diagnosing the issue - I'm not sure if there is some connection to upgrade of the HG633 router firmware to v1.21t which took place a couple of days before the issue started.

Are you testing over wireless?

It depends on what browser i use.

EDIT:

My results are via WiFi
