So I have a crazy question that I`m not sure anyone has tried or would know. But assuming that the Ethernet ports on a router not available for use due to reasons, what would happen theoretically if one were to connect the client Wi-Fi card to the router via an RP-SMA cable? Will it damage the hardware on either side of the connection? Would the frequency rated (2.4GHz or 5GHz or 915MHz) have to match on either end?
