Review of Linux Compatibility

The Edimax EW-7711UMn is a small WiFi USB adapter, which bases on the Ralink RT3070 chipset. The stick has the USB ID 7392:7711

Bus 003 Device 003: ID 7392:7711 Edimax Technology Co., Ltd EW-7711UTn nLite Wireless Adapter [Ralink RT2870]

and is automatically supported under latest Linux kernels by the kernel module rt2800usb (e.g. since Ubuntu 10.04 LTS (Kernel 2.6.x) or Ubuntu 12.04.2 LTS (kernel 3.5.x). The stick is automatically recognized when plugged in:

usb 3-2: new full speed USB device using ohci_hcd and address 2
usb 3-2: not running at top speed; connect to a high speed hub
usb 3-2: New USB device found, idVendor=7392, idProduct=7711
usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 3-2: Product: 802.11 n WLAN
usb 3-2: Manufacturer: Ralink
usb 3-2: SerialNumber: 1.0

and necessary drivers are loaded.

The EW-7711UMn exists in at least three different versions (V1, V2 and V3). But all versions use the RT3070 chipset and therefore are all automatically supported under Linux.

Alternatively, Edimax provides a Linux driver, which has to be compiled and installed by hand. For this driver the automatic loading of the rt282800usb driver has to be prevented by adding it to the linux kernel module blacklist:

sudo su
echo "blacklist rt2800usb" >> /etc/modprobe.d/blacklist.conf
exit
