Cisco Aironet wireless WPA encryption

Message

TheRedFox · #1 Post by **TheRedFox** » Mon Feb 09, 2009 9:37 pm

I have been able to use the WPA(PSK) encryption with the Cisco Aironet wireless driver under Windows XP using XP's Wireless configuration utility. I'm having trouble doing it under Xubuntu, and I was wondering if anyone had any ideas or experience.
so far, I have asked an extremely linux-knowledgeable person for help, and he tried to configure the WPA supplicant, but it didn't work, and then he tried to ndiswrap the driver, and iwconfig showed that it was connected, but the internet wasn't working. I was wondering if you all might know any good answers through your knowledge of thinkpads.

Install driver from https://gna.org/projects/airo-wpa/

wicd perhaps? It automatically configures wpa_supplicant. I haven't had the opportunity to try it though (all the networks I've used have been wep).

how do you actually use the airo-wpa thing. I've subversion'd it, but I don't know what to do with the files. any help?

Apparently the trunk version doesn't work. Do this:
svn co http://svn.gna.org/svn/airo-wpa/branches/kernel airo-wpa

Then I suppose you just cd into the dir and type make. Hasn't worked for me though.

well. it made and make-installed well. I'll have to wait to find out if it works though.
kind of off-topic, but does anyone know how to get trackpoint scrolling working? ArchLinux, incase it's relevent.
I've already tried this and adding something fairly similar to xorg.conf (I think i might've gotten the xorg lines from either this forum, the archlinux forum, or some other random site. I've tried several variations as well)

I can't seem to figure out how to tell wicd that I want to use the airo-wpa driver. any experience or links?

You "modprobe -r airo" then you "modprobe airo-wpa" instead.

do I need to add the airo-wpa module to anything? because, in the words of bash "module airo-wpa not found"

aaa · #10 Post by **aaa** » Fri Feb 20, 2009 4:15 pm

Then I guess the "make install" part didn't work properly. You can do "insmod ./airo-wpa.ko", in the directory that file is located.

okay. thank you. very helpful!
edit: the closest file in the airo-wpa directory to airo-wpa.ko that existed was called "airo.ko" i modprobe -r'd airo and insmod'd the airo from the directory. seems to work fine on the unsecured network where I am presently. It'll be a while untill I need it to have wpa encryption again, but when I do, I'll test it. another question - would it be safe to rename the airo module in the airo-wpa directory, so that I can tell them apart?

Don't see a reason why not. Nothing bad will happen, if some error occurs next time you insmod then just change the name back.

i changed the name, then insmodded it. my wireless works (on an unsecured network)
however, when I lsmod, i see an airo but no airo-wpa. also does anyone happen to know what option to choose in wicd preferences for using wpa with this driver?

I have the same problem on my T30 with the Cisco Aironet 350. I really dig the whole concept of Ubuntu but the wireless deal is starting to get on my nerve!

I've installed 8.10 and used the synaptic manager to install 294 updates which were a total of 275.4 MB long (downloaded with an ethernet connection)! I initially tried to use my wireless before updates which didn't work. The wireless signal from my router was detected but I could not connect to it. I spoke with someone in the Ubuntu forum and he suggested downloading the updates and the proprietary drivers. I forgot to download the proprietary drivers and just now read that they can be bad because they cannot be modified.

I'm lost with this.

I hope someone can guide me with easy to follow directions on how to use my T30 Cisco mini PCI wireless with Intrepid Ibex. I noticed a lot of people in the forums are super technical. I'm just learning and am not that savvy with the tech talk yet.

PS. I also have WPA-PSK encryption on our home router and it works great with XP.

Thank you.

Maybe this thread will help?

Wow. It seems if you want to get your T30 working out of the box you'll need a degree in computer science! Or have no life and spend countless hours in the basement tearing chunks of hair out!

I read those threads and am not sure which method to use. I also don't know what will happen if I make a mistake and how to correct it.

I could either: be fearless and trial-and-error my way through this nonsense OR go back to windows.

I don't have the first clue on how to extract and apply the ndiswrapper to my 8. 10 etc. These posts all see to be from almost two years ago also. I'm pretty sure things have changed since then. I'm going to the Cisco site and tell those guys there they stink! Hopefully they get some of this sorted out with 9.04 so it's more newbie friendly!

I attempted to use a WPA network the other day and wasn't able to... this was with airo-wpa. Wish I remembered the ndiswrapper deal, could have tried it.

TheRedFox · #18 Post by **TheRedFox** » Tue Apr 21, 2009 8:01 pm

i tried using ndiswrapper, but I couldn't figure it out, quite. I'm gonna see if I can get a PCMCIA from a friend of mine. He has a bunch of random assorted hardware and has used linux a lot, so he might have something.

I used NDISwrapper sometime back. Don't remember all the details, but basically you point it to a directory that contains the .inf and .sys files for your adapter. This can be on a Windows drive or on a CD that you may have copied them to (or sometimes on a hardware installation CD). NDISwrapper uses the your Windows drivers (usually drivers for Windows XP).

yeah, I remember trying that, but wlan0 didn't show up. but I'm using a PC card for now, so that's all good.
