I've installed Ubuntu 11.10 on my laptop Acer 5750. It detects wireless card and also lot of networks, but the problem is that it does not detect wireless network which is detected with my phone and another laptop (Has WinXP sp2 OS).
lspci|grep Network gives me only one line:
03:00.0 Network controller: Broadcom Corporation BCM43227 802.11b/g/n
What could be a problem ?
