I noticed the fibre connection was struggling every now and then the past week buffering youtube and generally being inconsistent, however gaming was fine.
Since yesterday I've struggled to game online without rubber-banding due to connection dropouts (not disconnections).
My IP is in the 1 range which I noticed some discussion about before.
Using ethernet not wifi.
I've run a bunch of tests to determine the cause and I seem to have a fluctuating download speed, and a lot of packet loss.
Your post about pre-tests and troubleshooting seems outdated so I've tried another router, reset everything, turned off the fibre box for a while etc. Tried the BTWholesale tests and other tests which I will attach:
Pingtest reports anywhere from 14-60% loss, btwholesale connected as their test username advised the service was found to be performing poorly.
