[SOLVED] New to Linux, Can't manage to set up WiFi Connection

[Meshinka7]

Hello, i'm running UNR on a Dell Inspiron mini 1012 (Dual Booted with windows 7). I right clicked on the network icon and added a new wireless network, filled in all fields, and chose connect automatically. The network icon still showed no connection, and when clicking on it this is what you get:

Wired Network
disconnected
VPN Connections >

I looked through the forum here and tried several things, including turning on wirless interface from the BIOS. Output of iwconfig gives:

lo no wireless extensions

etho no wireless extensions

pan0 no wireless extensions

and according to lspci my wireless device is BCM4312 802.11b/g.

Also, here is the output of the code at the forum sticky:

Was wondering if anyone could help, thanks!

[reed9]

You need the broadcom wl driver. If you have a wired connection, you can do

sudo apt-get install bcmwl-kernel-source

[Meshinka7]

There was a problem connecting using eth0 as well, which i couldnt figure out.. However i downloaded the driver software from the Broadcom website and followed the instructions in the read me file. Works perfectly now .

Thanks for the help! Chears!
