So sometimes you can't access the router's web interface via
http://192.168.x.x ?  If that is the case then it has nothing to do with

(and the cable between them, but cables usually aren't intermittently
bad).  I would, on such an occasion, try from both PC's to see whether
one of them might be the problem.  Right after that I would get a new

like "dig @ some.domain" when nothing seems to be working.
