Ubuntu Linux: Install RT2870 Chipset Based USB Wireless Adapter

This blog post listed Linux Compatible USB wireless adapters. It seems that many new Linux users frequently have problems learning how to install RT2870 driver under Linux. I also received email requesting installation instructions for the same device. This quick tutorial will explains how to install RT2870 based chipset device with WPA2 authentication and TKIP wireless encryption.

Our Sample Setup

The following instructions are tested on:

Ubuntu Linux 10.04.1 LTSKernel - Linux 2.6.32-24-generic-pae i686 (32 bit)WPA2 with Linksys 160N router RT2870 Chipset Based Devices Are Not Working Out Of Box

The main problem is conflicting driver which are shipped with default kernel. WPA2 is a method of security wireless networking with optional PSK for home users. The default driver only recognizes driver but always failed to join WPA2 based network. The solution is to install RT2870 driver from the vendor site.

Step #1: Disable Default Drivers

Type the following command to black list default drivers:
$ sudo vi /etc/modprobe.d/blacklist.conf
Append the following driver names:

blacklist rt2800usbblacklist rt2x00libblacklist rt2x00usb

Save and close the file. Use the rmmod command to remove current drivers or just reboot the system:
$ sudo modprobe -r driverName
# you need to remove all of the above drivers one by one:
$ sudo modprobe -r rt2800usb
OR simply reboot the systems:
$ sudo reboot

Step 2: Install Compilers

Type the following command to install required packages so that you can compile source code:
$ sudo apt-get install build-essential fakeroot dpkg-dev
Finally, install Linux kernel headers so that you can compile kernel device drivers:
$ sudo apt-get install linux-headers-$(uname -r)
