I dont' really want to kill my computer but I am having EXTREMELY irritating problems with it. I don't know where the problem lies and I need help. I have Vonage and get phone service without interuption, so I know the modem and router are working fine. But somewhere between the router and the computer it all goes to heck. The computer says I have a LAN connection, but I can't access the internet. The only think that works is turning everything off and rebooting....to include unpluggi...
