I have a router running OpenWRT backfire, with N and A/B/G being broadcast. A linux laptop, and a Mac laptop can see the N network and connect to it (or at least they could last weekend). But there is now a Windows 7 Desktop with a B/G/N wireless card, and a Windows 8 Laptop with a B/G/N wireless card that can't see the N network only the B/G broadcast. The B/G and N have different SSID's and Encryption ( WEP and WPA2 PSK respectively ). The N SSID isn't even visible. Does anyone have any suggestions as to how to troubleshoot further? Or what might be the cause?
