I have an office Dell laptop running windows 7 professional that is connected to a homegroup at office. when I try to connect the same laptop to my home wifi network (linksys wrt54g2), the laptop connects, network and sharing centre shows connected to internet, but I cannot access the DNS. error msg "windows cannot connect". Ping using www.google.com works. ping using 14.22.34.XX fails. I have tried the following: disabling the two homegroup related services through services.msc changing network type through home/work/public connecting the laptop through a LAN cable to the router my problem is, even at home, the computer shows it is joined to the work homegroup. in network map, an unknown "switch" is shown. When I try to see the homegroup settings, the next step shows computer not joined to homegroup. what am I missing? My other Win 7 starter netbook connects seamlessly to this network, as do my compaq vista home premium, nokia phones, iphone and other wi-fi enabled devices. Any solutions? what am I missing? thanks

What is the IP address you are getting? Update the drivers for your NIC and then try. Do a ipconfig /flushdns
