Upload speed 0.8. Have had 3x2.5 hour sessions on chat and they cant find a problem.

I work from home and use video conferencing most of the day. I have been doing this with no problems for several years. Talktalk have been no help whatsoever.

If you have a standard ADSL (i.e. non-fibre) service then that upload speed is about right.
