I’m not interested in using the switch button for this, but thanks anyway. I did look at your guide, but it didn’t seem applicable. And therefore, just to confirm I am doing things correctly: The Enet cable is plugged into the LAN port, and I’ve bridged the wifi with the LAN port. The WAN port is not connected. here’s how I have set it up in the LUCI interface:

This seems to work, except for one annoying problem: When I am connected to the “primary” AP (my ISP’s router/modem), I cannot access hosts connected to the AR-150. And the ISP’s router/modem doesn’t allow operation in “bridge mode”, and seems disinclined to cooperate with any user-supplied equipment. Any thoughts on this issue would be very welcome!
