I'm trying to set up a dual SSID AP with two different USB adapters. One is a RTL8821CU and is working as an access point, but FriendlyWRT doesn't load the drivers for the RT5370 Wireless-N. It shows under lsusb, but it won't load the driver. Both are AP capable. Has anyone done this configuration before? And is the supported usb wifi hardware list for the R4S really as narrow as whats listed in the wiki?
