Incoming signal constantanly fluctuates and stops

Hi 

Hope you can help, please. We have 350 MBPS service via a SH3 mostly to wired devices eg. Apple TV and Sky boxes plus a direct ethernet connection from the SH3 to a PC and another to a PlayStation.

We find the performance so erractic, sometimes fast sometimes v slow (wired speed test can range from 340 to 30  and on occasion nothing. 

Having look at the logs there seem to be quite a few errors I will post here, hope you can help as it is so frustrating.
