I have a Cisco PCI LAN+WLAN 802.11b card in my IBM ThinkPad T30 laptop.

Is this wireless card compatible with Lubuntu?

I have Lubuntu installed and it just won't connect. It keeps saying that it is trying to configure then it says that it is connected but it does not work.

I know that the wireless network is working correctly because I can connect to it with all my other devices and it works on this very same laptop when I am running Windows.

I added the following commands to blacklist.conf, but still no luck

blacklist padlock_aes
blacklist geode_aes

Try connecting with a Zydas WLAN USB 2.0 Adapter here.

It works for me, it cost £6.95 from Amazon.

Buying new hardware is rarely the answer. I'm going to try researching this. –  Githlar Oct 11 '12 at 8:35

Ubuntu (and all derivatives) should have a built-in driver for Aironet cards (as per here). First off, try blacklisting airo_cs (It's for PCMCIA cards only) and rebooting. If that doesn't work, read below.

Also see this page which says that the Aironet card does not support 802.11g/n or WPA2.

I also read somewhere that the airo driver makes a shadow of wlan0 as eth1. Try doing sudo ifup eth1 and see if that enables your wireless.

From information I found on the Lenovo site it seems that you have to install the Cisco Aironet Client Utilities (ACU). Here is a link to the search results that will get you where you want to go. You'll need to register for an account to download it though.
