@pinoy, the scripts works for AR150 immediately. Moving to the right side bridges the WAN, LAN. Wifi is also bridge to WAN.
@wayne47, I didn’t get a time to test on AR300M. But seems you are talking about wireless bridge, which is quite different from the wired-bridge. You have to make sure your router works as WDS and the mini router can connect to it as WDS mode. The original script only bridges WAN and LAN port but your wireless is not touched.
