10mbit upload drops to 1mbit during working hours

[robpalmer]

I have FTTC Fibre 2 which is rated at 10mbit upload (the maximum offered by BT to my house). Unfortunately I see this dropping to 1-5mbit during weekdays afternoons.

The consequence is that I look terrible on video calls for work.

An engineer was sent out who confirmed the line is fine. The Smart Hub 2 has been replaced. I am using ethernet cable direct into the router - it's not a WiFi issue.

Sync speed is good at 9.7mbps. During off peak times I can use the speed tester to get 9mbit upload speeds and it is fine. The problem is the variation over the day.

I have an open complaint with BT, but the lady keeps suggesting sending another engineer out, despite the first engineer concluding my house is fine and that any fix would need to be upstream of the cabinet.

in order for the forum members to help please can you post the stats from your router (if hub enter 192.168.1.254 in your browser) and if  HH5 then go to troubleshooting then helpdesk and if HH6/SH2 then advanced settings then technical log information . 

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

run btspeedtester with ethernet connection and post results - 1 when seem good and again when poor

I'd like to close this thread as I have determined the problem is not bandwidth - it s jitter.
