I have Verizon FIOS and it has worked well for about a year. All of a sudden my TV and Internet went dead. The TV came back, but I could not access the internet. I called for service, they replaced the router. Now two computers came back up but not my main one. I released the IP address and renewed it. My PC says my network card is good. I replaced the cable. When I launch Firefox or Explorer, I just get the message "Server not found". I am not very computer saavy, so I am desperate. Any of you computer geeks out there have any ideas. I really appreciate it. Thanks.
