Lenovo X121e no WLAN found

[bnubu]

Hello

A week ago I received my net subnotebook x121e from Lenovo. Windows 7 64 was preinstalled but i replaced it by ubuntu 11.10 (3.0.0-13-generic x86_64) . Now everything works fine except I can't connect to a wlan. In fact the network manager doesn't even find any network. I searched the web for a solution but I got nowhere. I need to add that I am new to the Linux world so I hope I didn't make any stupid mistake...

Here some information:

It would be great if someone could help me since I've got no plan what I could do nor where to start. By the way please excuse my english, it's not my native language.

Thank you very much.

Your laptop is very similar to mine (Thinkpad Edge 11").

Try here for a solution that worked for me.

[alco75]

Infact BCM43224 is exactly the same device as mine, so I bet blacklisting bcma and brcmsmac will work on your laptop too.

It worked!

Thank you so much. This ends a series of nerve-racking failled attempts.

Have a nice evening

Hi, even I have a x121e i3 processor with the broadcom chip for WLAN. When I scan for iwconfig it returns no wireless connections ??

There seems to be no drivers installed. I did try to install broadcom sta drivers without succeeding. Sorry I am not familiar with how Linux works so any help will be appreciated. I have installed ubuntu 10.10 with OSIAN environment from a live USB. I believe the Atheros Ethernet port won't allow me to access internet from an Ethernet cable as well !!!
