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 1.4.0.0 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.

 

Installation

 

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

 

1. Retrieve the driver

 

wget http://www.ralinktech.com.tw/data/drivers/2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2

 

or (faster link)

 

wget http://razor1394.wippiespace.com/public/gnu_linux/2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2

 

2. Extract the compressed driver directory and files.

 

tar xvfj 2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2

 

3. Enter the new directory

 

cd 2008_0925_RT2870_Linux_STA_v1.4.0.0

 

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. 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 this module into Ubuntu.

 

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

 

PS.

 

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.

 

Unload

 

sudo ifconfig ra0 down

sudo modprobe -r rt2870sta

 

Load

 

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?
