Upload Speed Problems

[#1]

Hello,
Unfortunately recently my upload speed has been playing up. Usually, my upload speed is already unsatisfactory and is around 0.5 kbps, but now it drops randomly to 0, and any uploads stop. Is it possible to uncap my upload speed or is there another solution. I am on a FTTC plan.
Thanks.

It won't be capped but it does sound like either your sync rate is low on the upstream side of things or that there are errors on the line causing throughput issues at your end.
I would suggest raising this at;

Good luck in a speedy fix
