Internet Keeps dropping out for a few seconds

I'm having an issue where my internet connection will drop from anything from 5-30 seconds.

The PC's are hard wired into the router. 

I've factory reset the router but to no avail.

Re: Internet Keeps dropping out for a few seconds

Rather too many upstream timeouts, network log is a stinker and confirms your connection problems, and (in my view) the 4 dBmV power range on the downstream is at the limit of what the hub can cope with.  I'll mark for the forum staff to take a look and advise.
