As advised above, post RS are too high on the downstream top end channel.
At a guess though, your upstream is the issue- The 22 T3's, accompanied by RCS partial service in the logs LOOKS like your losing upstream channels as the power level increases over time. TBF thats a guess, and you would be best advised to try the phone to get a tech out.
Thanks for the help, my internets always had the t3s happening,had bout 6 engineer visits they never find anything wrong feel like im wasting my time even phoning the offshore customer service had my router replaced few months ago too.
