Absolutely abysmal upload on my 100M during working hours

I know Virgin's upload can be an issue but this has been an absolutely joke in the last 2 weeks

Download has been fine, generally 80+ during the day time but upload struggled to go beyond 1M from 9:30am to 7pm. Video calls and online teaching has been very difficult.

I have called Virgin on multiple 1 hour+ calls, first technician has tried various signal setting on her end plus having me complete a hard reset. None helped. Second technician the advised me there is area improvement (area 22) until Mid Feb and filed on complaint. The problem is, my neighbours don't experience the same problem, or at least as bad since they don't notice. Surely Area work would affect all of us?

I have setup a BQM and waiting for it to run for a few days. Wonder if this is just pure congestion in the area that simply can not be solved? (hence just getting all sorts of explanation from VM)

Re: Absolutely abysmal upload on my 100M during working hours

Just to add, all of above is done via both Wireless and Ethernet connection on the Hub3. The speed goes back to normal late in the evening (up to 10Mbps but I will take anything above 5 and not complain)

Can I ask what postcode you are in Area 22?

I'm in area 22, postcode IG9 and having similar terrible performance.

Looks like congestion:

However one of your upstream channels is out of spec on QAM, which normally indicates noise on the line:
