Just bought a used f7d8301 router on Ebay. With the factory firmware The WAN port was not working. Installed tomato tomato-K26USB-1.28.RT-N5x-MIPSR2-115-BT-VPN.trx and still no WAN. All the LAN ports seem to work, just not the WAN. Is there a way to check if it is something with the hardware. If it is something with the hardware, can one of the LAN ports be changed to a WAN port.
