Wireless connection no longer works with Ubuntu 8.10

Could you please post the output of an lspci?

Also, you may want to ensure that there is not a driver available for it in System | Administration | Hardware Drivers.

nothing in system --> administration --> hardware drivers.

here's the lspci output -- wireless device seems to be what i think it is:

Try doing a:

sudo modprobe ipw2200

Also, you may want to look for the ipw2200 firmware

I found this from another person who was having an issue:

"I looked for the firmware in the /lib/firmware/2.6.27-2-generic directory, but it wasn't there. I went back to the /lib/firmware/2.6.24-21-generic directory and found the ipw2200 firmware files. A quick "sudo cp ipw2200* /lib/firmware/2.6.27-2-generic" and a reboot fixed the issue for me and now my"

If you use the live CD of 8.10 does wireless work?

Tried the second suggestion -- copying the older firmware into the newer kernel folders -- first. Sounded like exactly what I was looking for -- but it didn't work.

Rebooted, made sure ipw2200 files were in right place, still no connection. Ran lshw again, wireless network chip still "UNCLAIMED."

Then tried installing the drivers from the Win XP partition using ndisgtk a few times -- but the drivers seems to have some kind of conflict with the 2.6.27 kernel. (I tried this as well before copying the older firmware.) And they didn't work anyway using older kernels. Nor did the native drivers in those kernels.

sudo modprobe ipw2200 yields nothing, just bounces back to the prompt without a message.

I really think the problem is with 8.10 Intrepid Ibex somehow, and not with the kernel. Gonna try live disks of both 8.10 and 8.04 to see what happens.

Yeah... I was reading some more on your problem and a few people said they had to do clean installs to get their wireless to work. I hope that is not the case, but that is what they found success with. I would not do a clean install unless the 8.10 CD works though.

I was actually going to try to revert to 8.04 somehow, but I guess a clean installation of 8.10 might be worth a try. Gonna back up whatever private data I have (there isn't much) to the XP partition beforehand just to be safe.

Will let you know.

Well, the 8.10 live CD does NOT work in getting a wireless connection. Burning an 8.04 CD right now (I'd upgraded several times from 6.04 or 6.10, can't recall exactly which), and we'll see if that works.

I had no issues with 8.04 and two laptops with ipw2200 wireless cards... but I have not loaded 8.10 on those yet.

Ha ha, then my advice is "don't."

I tried the 8.04 live CD and that wasn't able to connect wirelessly either. So maybe it's my setup.

In any case I've learned NOT to use Windows drivers with ndisgtk -- it creates a conflict with the ipw2200 files. Though I suppose I could try one more time nixing the ipw2200 files and then reloading the windows drivers, but I think I tried that already.

Anyhow, I tried doing a clean install of 8.10 but the partitioner didn't want to cooperate without nixing my Win XP partition.

I officially give up -- for now.

There should be no need for Windows drivers. Do you have any local LUGs in your area that would be able to give you hands on help? It might be your setup; it is always difficult to assist when text there is to work with.

I have Ubuntu 8.04 and wireless works fine. Ubuntu 8.10 always fails to connect, it sees the ssid and lets me put in the password but fails at "Requesting network address". I don't think this is Ubuntu, I think it is the kernel because 7.10 didn't work with LAN but DID work with a different broadband router. openSuSE 10.3 works fine but 11.0 and 11.1 have the same problem. LAN (ethernet) works always.

I used to have a laptop with Ubuntu 8.04 and it had the 2200BG wireless and it worked fine, havn't tested 8.10 on it yet.
