I've been using ndiswrapper and the Windows drivers for the Ralink RT2700E wireless card in my MSI Wind U100 432US. It turns our that the kernel included with Ubuntu Jaunty now includes the native Linux driver for this card. I'm not sure when this was added to the kernel, but I'm using version 2.6.28-15.
If you've been using ndiswrapper you'll need to disable it first. This is done by removing the ndiswrapper kernel module using the modprobe command. Open a terminal and enter
You can now try out the RT2860STA driver by enabling the proper kernel module.
You should now be able to see a "new" wireless device called ra0 listed in the results of iwconfig.
You'll need to reconnect to your wireless network using Network Manager or whatever tool you use to connect to wifi.
If everything is working OK for you with the new driver, there are a few steps you need to take to make sure the changes hold after a reboot.
You need to blacklist ndiswrapper to keep the module from loading on the next boot. Edit /etc/modprobe.d/blacklist.conf
Add this line to the end of the file and save it.
Load the rt2860sta module at Boot Time
Edit /etc/modules to force the rt2860sta driver to be loaded when you boot.
Add the following and save the file.
You are now running your RT2700E wireless card with the native Linux driver.
