I have three computers connected via wired method to a 4-port Linksys router. Everything has been working fine for the last several months. Today, connectivity has been very erratic. Cable company says everything is fine on their end. I’ve done nothing differently, software or hardware wise to cause any changes.

  If I unplug the router and then plug it back in, I will have restored connectivity for about 10 minutes. Then it’s dead in the water. So I thought maybe the router is going bad?

  But if I plug the cable modem directly into my computer, I get *NOTHING*. It thinks I’m working offline. I can’t connect at all! So I thought maybe the modem is going bad?

  But do modems “go” bad? Doesn’t it either work or not work? Why would it work for a few minutes before dying?

  I don’t know much about the intricacies of networking. Everything plugs in, I don’t do anything fancy, just want to get on the internet. All worked fine until today. Any tips would be helpful.
