Wireless Receivers Works Well! A Wireless Receiver That Works On Linux?

A wireless receiver that works on Linux? - wireless receivers works well!

I connect a desktop with Ubuntu Linux, the need for a wireless network with WPA2 Personal TKIP + AES security in touch. I want a receiver that broadcasts via a standard Ethernet cable and not via USB. The alternative is that the Linux machine should be supported. My budget is $ 50 in most, preferably less. Ideas? Thank you in advance.
