The external WiFi adapter you bought is not compatible with free systems (the
firmware is nonfree), because the chipset is Ralink:

I recommend Technoethical WiFi adapters and cards:

The WiFi card could solve your problem permanently, provided you can replace
the nonfree BIOS on your laptop. AFAIK, there is no free BIOS replacement for
the X220.
