Ralink rt2870 (USB) Ubuntu Intrepid Ibex RELEASE / Jaunty Jackalope alpha HOWTO
This is an howto on getting the 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+.
Installation
It was tested on 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 the driver. The first four steps can be done in Firefox and Nautilus if you wish. The second last should be used in the Gnome terminal.
Open up the gnome-terminal (ALT-F2 -> input gnome-terminal -> ENTER).
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
Extract the compressed driver directory and files.
tar xvfj 2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2
Enter the new directory
cd 2008_0925_RT2870_Linux_STA_v1.4.0.0
You need to change some info in os/linux/config.mk to make it compatible with NetworkManager. Replace that file with the one attached to this wiki.
Compile and install.
sudo make
sudo make install
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.
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
