I just installed Ubuntu 8.04 LTS Destop on a IBM T22 laptop and it works fine when plugged into the DSL connection. The wireless connection is not working. The card is a Cisco Aironet 350 (Air-PCM352). I do not see by wireless network in the Network Manager. I tried checking for device recognition by opening device manager (System>Preferences> hardware information) but found that "hardware information" was missing from the menu. I appreciate your expert advice.
Thank you,
Bob

I think the PCM card was not firmly connected to the laptop when i installed UBuntu. Do I have to totally reinstall Ubuntu to get the PCM card to work?
Thanks,
Bob

Remove any ethernet cable from your machine and restart Ubuntu. You should not have to go through a full install for Ubuntu to detect your wirleless card. Does the wireless card configure itself now?

You may also want to book mark this page for later on just in case there is no Linux driver in you configuration for the card:

But lets so how a restart goes first without the ethernet cable.

Mapes,
I did as you requested and the computer does not see the wireless network. How do I install the LINUX driver for the PCM 352 card?
Thank you for your help,
Bob

I rechecked here:

https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsCisco

and it looks like your card is supported.

Open a terminal window and type:


sudo lshw -C NETWORK

Post the output back here.

Ubuntu has found your card = good.

Now see if the card can handle packets. At the Terminal type:


ping -c4 127.0.0.1

What do you get?

These are you wifi drivers.

The ping requested is perfect. Now see if the card can find your router:

Doh! That means you have been talking to the wrong network adaptor :(

If you have an ethernet cable plugged in that acts as the default network interface. In other words the wifi card doesn't initialise. TAKE THE CABLE OUT then have another go at getting the wifi card up.

And checkout the stickies like this thread:

I installed the WICD network manager and it works fine with the wired connection. The laptop still can not see the wireless network. The lights on the PCM card do not blink. The activity light comes on when the laptop boots up then both the status light and activity light stay off.

Looks like the drivers are there but I don't know why they are not initialising with the card at boot up?

You mentioned in a previous thread that when you installed Ubuntu the card wasn't properly seated and wondered if a reinstall would fix the problem. Unless other posters can figure out an alternative solution then I'm coming around to that idea.

If you do a fresh install make sure the wifi card is firmly in place and disconnect the ethernet cable. The install routine may have better look this way.

Mapes,
I reinstalled with the cable unplugged and still can not see the wireless network. Thank you for your help. I am sending the problem to the nm team. It might be some sort of interaction between the Cisco card and the IBM T22 laptop that is the problem.

Many thanks for your time and knowledge,
Bob

Mapes, I am stuck at the same point as you are - can see the drivers but they do not load and the 350 has one light - activity - in Orange/solid.

Anyone have any luck getting the 350 and WICD to work?

Thanks.

I read your feedback up to this point with interest as i thought you might resolve my similar problem too, however, when i entered the comment line "sudo lshw -C NETWORK", i did not receive any output!
I assume my wireless is not being recognised and wondered what the best course of action will be to rectify this?
Hopefully you can assist.
many thanks in advance.
