Netgear 8-port router FVS318G troubles - fixed!

We've been having troubles with our home network going down randomly.  It was getting worse and worse.  At first, I blamed Comcast, and there was indeed a problem there, but a technician came out and fixed that.  I finally figured out that the culprit must be our Netgear 8-port firewall router.  I think it has a relay in it and those eventually fail. (It would be nice if they supplied a circuit diagram, but that was the old days.)  This router was in use for years, not sure how many.  So I got a new FVS318Gv2 and installed it.  Bingo, no network problems.
