My home network has been up and working, no problems, for about 9 months, using a D-Link 614+ router. 3 computers are hard-wired in, 1 computer accesses wirelessly with D-Link 520+ PCI card, and my Audiotron is connected wirelessly with a D-Link 810+ bridge. Router is set to act as DHCP server. All of a sudden, the wireless computer can't access the network or the internet. I've checked workgroup names, etc., and nothing has changed. The computer shows that it is connected to the network, but there are NO packets being received, and this computer isn't getting an IP address. The other wireless device is still working flawlessly, so I think the router is working OK. When I go to the router set-up from one of the wired computers, the MAC address from the problem computer's card is showing up as a wireless device (under the Status:Wireless tab), but no IP address shows up (General : DHCP tab). I've tried re-seating the network card in the problem computer, moving it to a different slot, changing the network to fixed IP addresses (it didn't work, so I changed it back). Still no luck. It shows as connected to the network with good signal strength, but absolutely no traffic to that computer. Any ideas? Thanks in advance.
