RTA2870sta 802.11n Working in Ubuntu (AWUS051NH)

**smashin** · April 29th, 2011

Hello,

I've just working this drivers in N mode really fine. They just broken in the upgrade.

My USB dongle is ALFA AWUS051NH

These are the steps:

1 - Download RT2870USB(RT2870/RT2770) from: http://www.ralinktech.com/support.php?s=2
It's version 2.4.0.1 (07/09/2010)

2 - extract the package and edit /path/extracted/../os/linux/config.mk
and set:

Code:

# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y

# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

3 - Because new kernel has this wireless drivers in other path, edit /path/extracted/../Makefile

Look for that:

Code:

LINUX_SRC_MODULE = /lib/modules/$(shell uname -r)/kernel/drivers/net/wireless

and change to

Code:

LINUX_SRC_MODULE = /lib/modules/$(shell uname -r)/kernel/drivers/staging/rt2870

4 - make

5 - make install

6 - edit the file /etc/modprobe.d/blacklist.conf
and add

Code:

blacklist rt2800usb
blacklist rt2x00lib
blacklist rt2x00usb

7 - Restart the computer.

8 - OPTIONAL: Config file in /etc/Wireless/RT2870STA/RT2870STA.dat

Why go through all that when compat-wireless is a whole lot easier.

Here is my "lsmod |grep rt"

Code:

jawilljr@jawilljr:~$ lsmod |grep rt

lsusb |grep Ralink:
