problem setting up Wireless on Laptop (Ubuntu 10 LTS)


i recently tried linux again on my laptop (studio 1555 with vista home premium 64bit) and used wubi to install Ubuntu (it seemed the safest option)
when i put the same OS on another laptop, wireless networking worked fine
when i try to access any network with this install (it doesnt say "wireless networks are available" either) i cannot connect.

i suspect it is a driver problem, but i have never touched drivers

any help?



(PS i only put the ssid and wep key in and left the rest on auto)

It is likely a driver or firmware problem and probably easy to fix. (Especially if you have access to a wired connection briefly.)

We need more info though.

Please post the output of
Code:
lspci -vnn
lsmod

This is your wireless card
Code:
04:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)
Subsystem: Dell Device [1028:000c]
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at f8000000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: b43-pci-bridge
Kernel modules: ssb
The b43 driver is loading, but support for that card with that driver is fairly recent and may have problems. I would use the Broadcom wl driver. If you have a wired connection install with
Code:
sudo apt-get install bcmwl-kernel-source bcmwl-modaliases
I believe it will automatically blacklist the b43 driver, but if not do
Code:
echo "blacklist b43" | sudo tee -a /etc/modprobe.d/blacklist.conf
If you do not have a wired connection, the necessary files are on the installation CD.

put your install disk in and do this.

For Ubuntu Linux, go under the System Menu -> Administration -> Hardware Drivers. You should get an option from there to use/enable the proprietary wireless drivers if they exist.

you know it amazes me why I test theses system help write guides per distro. when the open source bcm_sta driver that has become stable is put on the disk so if that hardware does exist it will install it with out being on line. Ubuntu team worked on this and did a good job on my last test install on different hardware.
I guess Linux people are just good old hackers.
Put disk in and enable hardware. wow. to easy.
