Static charges can make a router (or some card in a computer) 
malfunction, even for an extended period of time -- to subsequently 
start working perfectly again.
It used to be VERY common with computers some 20 years ago.  (My clients 
were mostly in industrial areas which often had power spikes.  More 
recent computers are a lot more resistant to problems.)

I had similar problems with my router a few years back (for several 
months), and more recently for 2 months my video card displayed all but 
the simplist colours in green.  (Very frustrating for displaying 
photos.)  But both work perfectly since.

So probably not useful to replace your router.  (Although a backup 
router might be reassuring.)
