Hi,

I have a
Bus 001 Device 002: ID 7392:7711 Edimax Technology Co., Ltd EW-7711UTn nLite Wireless Adapter [Ralink RT2870]

Which under Pfsense can be used as a wireless access point, however for one reason or another I decided to roll my own Linux based router/ap.

Debian sees the usb adapter without issue, however if I try to configure it as a master I get the following:

iwconfig wlan0 mode Master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.

The adapter is capable of Master mode as it worked in Pfsense, so is it a Linux driver issue? And if so is there anything I can do?

Thanks
