Hi installed a clean install of ubuntu 12.04 on a dell inspiron 1501.
according to sudo lspci -nnv
my wireless card is listed as:
Broadcom Corporation BCM4331 802.11b/g WLAN
Subsystem: Dell Wireless 1390 WLAN Mini-Card
Flags: Bus Master, Fast devsel, latency 0, IRQ 18
Kernel Driver in use: wl
Kernel modules: wl, ssb
It just won't find any wireless networks, i have previously tried to install the windows drivers using ndiswrapper
sudo modprobe ndiswrapper
returns and error FATAL: Module ndiswrapper is not found
Can anyone help? Since I'm new to Ubuntu please let me know what extra details you want and I'll update this post with the info
