Is it possible to use the AR300 as WiFi repeater mode (no Ethernet cable) but have it get the DHCP from my main router? I would like for my main router to do all the DHCP/DNS/wan routing. Basically my idea is, set up a remote access point (different ssid tho) with no eth wires.
… otherwise LuCI + the OpenWrt Forums is the next stop.
More Settings and Extender mode is the answer
