I just installed Ubuntu 12.04 LTS on a brand new (no OS) ThinkPad Edge E335. Everything seems to work just fine, but there appears to be no driver for the wireless hardware (WLAN ThinkPad 11 a/b/g/n).

There also seems to be no support on the Ubuntu Certified hardware site. Lenovo itself offers only windows drivers.

Will it follow soon or should I maybe try Ubuntu 13.10?

Any other solutions? Has anyone had the same problem?

It might be helpful to edit you question to include the output of running lspci -nn | grep 0280 in a terminal so people can see what wireless card your computer is using. –  David Edwards Jan 15 at 10:42

I really don't know what happened, but suddenly tonight a driver appeared! Yesterday night I spent two hours trying to find the driver, but the update function didn't find any...

Tonight, just to give it another try before doing further steps (the ones you kindly proposed), I started the "normal" search within the system information update function...and there it was!

To answer some questions: yes, it is actually a Broadcom BCM43228 802.11a/b/g/n [14e4:4359].

So, basically you all where right and your tips would have worked, I guess.

Thank you so much for the quick comments and answers!

Try this:

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

Reboot pc afther and see if it works.

Are you quite certain he has a Broadcom card? Not all Broadcoms are correctly driven by bcmwl-kernel-source. –  chili555 Jan 15 at 14:35
    
Not sure, but i noticed that a lot of the users have this problem with Broadcom. One user didn't even had Broadcom and this still helped him... I don't know how or why. So i usually sugest this method first when somebody has wireless problems since it could be the fastest and easiest way to fix, if not I usually delete my answer. –  Rat2000 Jan 15 at 15:24
