Ralink rt2870 (USB) Ubuntu Intrepid Ibex RELEASE / Jaunty Jackalope alpha HOWTO


Update! Ubuntu Jaunty 9.04 testing now includes the rt2870sta driver. It should work right out of the box unless you have an unsupported usbid.


This is a howto on getting the Ralink rt2870 Wifi 802.11abgn chipset to work with Intrepid Ibex 8.10 RELEASE i386 and amd64. It has also been tested on Ubuntu Jaunty Jackalope i386 alpha 3+.

It was tested with two ENGENIUS EUB-9701 EXT - EUB9701X2 which contain the rt2870 chipset made by Ralink. Since the driver it is very easy to install and use the driver. Steps 1-4 can be done in Firefox and Nautilus if you wish. Steps 5-7 should be done in the Gnome terminal.




Open up the gnome-terminal (ALT-F2 -> input gnome-terminal -> ENTER).


1. Retrieve the driver


          with a browser (firefox/chromium/chrome/opera/seamonkey)


         from here http://www.ralinktech.com/support.php?s=2         


or retrieve from the wiki


wget http://ubunturt2870.pbworks.com/f/2009_0820_RT2870_Linux_STA_V2.2.0.0.tar.bz2


2. Extract the compressed driver directory and files.


tar xvfj 2009_0820_RT2870_Linux_STA_V2.2.0.0.tar.bz2


3. Enter the new directory


cd 2009_0820_RT2870_Linux_STA_V2.2.0.0


4. You need to change some options in os/linux/config.mk to make it compatible with NetworkManager or more precisely Wpa supplicant. Replace that file with the one attached to this wiki. If you don't want to use the file on the wiki open the existing file in your driver directory and change all wpa_supplicant related lines to yes (y instead of n).


cd os/linux

rm config.mk

wget http://ubunturt2870.pbwiki.com/f/config.mk


5. Now get back to the root of the driver directory


cd ../../


6. Compile and install. 


sudo make

sudo make install


7. If you are using Karmic koala you need to blacklist the new kernel driver as it doesn't work so good for the moment


          sudo echo rt2800usb > /etc/modprobe.d/blacklist


8. Modprobe the new driver if you want to use it instantly


sudo modprobe rt2870sta


Networkmanager should see your available networks within one minute.


The driver should autoload on each reboot.


Please push the Ubuntu developers to integrate an updated version of this module into Ubuntu.


The rt2870 chipset will within time have support within the Linux kernel (rt2x00).




If you want to restart the driver you have to take the interface down before modprobing then doing the opposite when bringing it back up.




sudo ifconfig ra0 down

sudo modprobe -r rt2870sta




sudo modprobe rt2870sta

sudo ifconfig ra0 up


NetworkManager has a tendency of dying when updating an Ubuntu Intrepid or Jaunty system.


Bring it back up


sudo NetworkManager


Sometimes NetworkManager hangs.


Kill it and bring it back up.


sudo killall NetworkManager

sudo NetworkManager


Ralink rt2870sta webUI


Ralink does also provide a webUI at the same page of the driver. I have installed it but not gotten it to work.




Maybe it does work better for you?
