With consumer grade router/modems I've found the capacitors are of a low 
rating and therefore within a few years (or sooner if your area experiences 
brown outs and power cuts/surges) they give up the ghost.  Replacing the 
capacitors in their power supply and sometimes a couple of their internal 
capacitors with capacitors of a higher rating for just a few cents, by passes 
this built-in obsolescence and extends their useful life for quite a few more 
years.
