I have a TPLink TL-MR3040, Flashed with OpenWRT Chaos Calmer 15.05, and want it to use a USB Wifi adapter (I have a few RT5370's sitting around, but willing to get what's needed), and would like to configure it as a wifi repeater, where the WAN side uses the USB adapter, and will have a different IP range than the LAN side. I came across directions to make a repeater, but I don't know how to get the MR3040 to recognize the USB Wifi adapter. After searching, all I can find is that it looks like it's supported.
Thanks for any help!
