Comment 69 for bug 541620

I am using HP Mini 110 netbook with Ralink RT3090 wireless chipset.

I also faced this problem. However, I fixed it by downloading and installing the latest driver from http://www.ralinktech.com/support.php?s=2 .

Before building and installing the driver, you need to ensure the packages "build-essential" (or at least GCC) are installed. If you did not install it before, and cannot connect to the internet by using wired LAN, you have windows and can boot to Windows, or you can access another computer which can access internet, follow these steps:

1. Run Synaptic Package Manager, mark the package "build-essential", the other required packages will be automatically marked for you.
2. Then, in Synaptic Package Manager, click file -> Generate package download script, then save the generated script into either your USB Flash Drive or external hard disk drive.
3. If you can boot to Windows, and your windows can access internet, you open the generated script file, you will see a lot of URL inside the files. Paste those URL on your web browser or any download manager software to download the required packages. You can also open the script files and download the packages on another computer that can access internet.
4. Save all those downloaded packages into your USB Flash Drive or external hard disk drive.
5. Also download the RT3090 driver source files from the above website to your USB drive.
6. Back to the Ubuntu on your computer, run Synaptic Package Manager again, click File -> Add downloaded packages, then go to the directory of your downloaded packages, click OK. The packages will be installed. You can now proceed to build the new driver.
7. Extract the downloaded driver source files to any directory.
8. Open terminal, go to the directory where you extracted the files to, then run "sudo make" to build the driver.
9. Run "sudo make install".
10. Either restart the networking services or reboot your Ubuntu.
11. Enjoy your wireless internet.
