Local area connection doesn't have valid ip configuration

The way the house is hardwired, the outlet in each room is wired to a box on the wall in the laundry room. From there, there is a cat5 cable that goes to the router. So switch A computers in one room can only reach switch B computers via the router.

I tried static and dynamic IP configurations last night without luck.

Yes, reset the router to factory too.

So yeah, I'm thinking the router is dying. Which sucks because it's only a year old.

Thanks for your insight TerryNet!
