Some more info would be helpful.
What brand and model of desktop.
What model and brand of router.
What have you done to this point to trouble shoot.
Have you entered the network password into the desktop and is the network adapter enabled.
Has the desktop previously been able to access the internet through what you have now for service and network.
You're right; I should have included more info. eMachine model ET1161-O3 (or 5). AMD Processor LE 1640. The modem is a D-Link from Verizon. The computer also seems to hae an LSI PCI SV928P Soft Modem.
I've turned everything off for (more than) 10 seconds and rebooted. WiFi works but PC can't connect. Changed ethernet cable twice. Checked all connections more than once. Verizon ran some tests from their side and concluded the problem was my PC; I don't know which tests they ran.
I'm thinking maybe the modem card?
