Hello,
I have got two Operating Systems in my notebook: WINDOWS VISTA (WV) AND UBUNTU 8.04. With WV I do not have any wireless problem, but with ubuntu... it does not detect any wireless connection. At home (I am in a foreign country studying) I used cable/wire connection with an ADSL modem.
I did most of the steps of the Ubuntu Linux Help, ubuntu recognize the hardware but I could not see wireless connections. In addition, I could not switch the wireless device on (please see the attached TERMINAL REPORTS: Terminal: 1. lspci, 2. sudo lshw -C networky and 3. iwconfig)
