My Asus A54C TB31 running Windows 7 fails to connect to a certain Wireless N network. To be more specific, it shows that it is connected but there is no internet access. I have tried disabling all services and all startup items, removing McAfee's protection, turning it into an Open network, and updating the drivers for the Wireless card.
I am seriously running out of things to check. This computer works on other networks (I believe N, but have no way to check right now). It claims to support b/g/n networks. I can ping other computers in my network, but I can't access the gateway directly wirelessly. Also, the ISP-provided access point/router/modem does not show that the device is connected. The ethernet card works in the same machine.
