If I plug in to my router directly I can browse my workgroup, access all shares without a problem. When I disable my onboard LAN card and enable wireless, I can't browse my workgroup or even ping the other computers by name or IP on my network. I can browse the internet wirelessly, ping the router and the IP and subnet are the same when I'm using wireless or wired connection. I removed and added client for MS networks, file and print sharing, removed all wireless security from my router and it still does not work. I don't know if its my Dell wireless card or an OS problem and don't know what else to try. Any ideas?
