My desktop computer's LAN adapter is connected to the internet by ethernet cable to a Trendnet TEW-450APB access point (only 1 port). This AP is configured as an AP Client which connects wirelessly (by point to point external antennas) to a remote network 500 ft away. The desktop computer hard wire connection works fine, but I need to extend wireless coverage to the rest of the house. I have a Rosewill RNX-N150RT (Atheros chipset)with DD-WRT but have not been able to get a successful configuration. Everything I read on the forums assumes you have physical access to the ports on the master router. Can someone provide assistance on how to configure the DD-WRT router to provide wireless coverage in this oddball situation?
