You re not mentioning what software you re using to connect to wifi. For your case I would check 2 things: 1) `dmesg` output to check if you see any errors from your network card driver or if its loaded correctly. 2) The output of `iwlist scan` to see if the network you re looking for is detected from the hardware.
