OK, let's try setting the Win7 machine with static information....hold the Windows Logo key on your keyboard and strike the R key, this should bring up the run dialog box, type ncpa.cpl and hit enter. In the network connections window select your wireless adapter and then right click and choose properties. If IPv6 is checked uncheck it for now. Highlight IPv4 and select the properties button, in the resultant box select "Use the following IP address" radio button. Enter 192.168.1.254 for the IP address and then hit the tab key, this should auto populate the subnet mask box with 255.255.255.0 in the default gateway box enter 192.168.1.1 in the DNS server boxes use 188.8.131.52 for preferred and 184.108.40.206 for the alternate. Ok your way back out of there and open a command prompt and type ping 192.168.1.1 let me know if any of this works.
