I bought a Diamond wi-fi adapter that's advertised as being compatible with Linux OS's. Turns out, according to Diamond tech support, it's compatible with tlx but i can upgrade to tlx without going on line with the computer needing the upgrade. Diamond tells me to ask the person who installed Linux to tell me how, and he says he's never heard of tlx. Can someone reading this tell me how to upgrade my Ubuntu 12.04 to tlx so i can get on line? Thank you.
