Big, big update.

To me it seems you are missing out on a couple of basic things:

  • A driver is a software module that needs to match both, your actual kernel version and your actual make and model of your device. So, if you have a Ralink RT5370, as your lsusb log indicates, you should use the Ralink driver indeed. The Realtek driver will not help you in any way with this.

  • To find out what driver you need you can:

    1. look at the device itself. Most of the time you'll find a very good identification printed on it. Google is your friend.
    2. use the tools in your computer like lsusb, lsmod or lspci. Google for the device ID's.

If you build your driver from source, and it does not build with your actual kernel version, try building with another kernel version. With linux it is really easy to switch kernel versions at boot. If you need help to install an older kernel version, follow this post to Install older kernel version.

if you positively identified that you have a Ralink RT5370

You probably should follow the instructions from here, here or here.

if (and only if) you have a RealTek 8188:

Try this from google code. It's patched driver from realtek.

But you have to blacklist the native drivers: put a file in to /etc/modprobe.d/ with the following in it:

# Blacklist native RealTek 8188CUs drivers
blacklist rtl8192cu
blacklist rtl8192c_common
blacklist rtlwifi
