I'm running Ubuntu 13.04 having just reinstalled to see if it fixed the problem, I have installed the wireless drivers and they appear to be functioning as I am picking up the WiFi in the hotel down the road! It is not however, detecting the wireless router nor the booster in our house (and I'm next to the booster connected via cable just to type this out!)

I'm running out of ideas, I've updated the headers and it won't reinstall the driver. I just can't fathom why it wont pick up those networks as the other 4 computers in the house can - main difference being they are all running Windows 7/8

Does the laptop have windows installed? does it pick them up in windows? Could it be a wireless G only card maybe and router is running N or better? – Andy Jun 26 '13 at 12:57
