wireless for T-40

[Przemian]

Hi,

I installed Ubuntu and I cant get my wireless connection to work. I found that I need ndiswrapper to update my drivers following the sticky post in here. However there is a problem, because I cant successfully run ndiswrapper on my system.
Please help.

Ubuntu 9.10, IBM ThinkPad T-40, what am I doing wrong?

I am answering this post from my T40. I am wondering which wireless chipset yours has that doesn't work natively. What have you tried to get the wireless to work?

[Przemian]

Cisco Aironet Wireless 80.11b

I'm very new to ubuntu, so I tried to read as much about this issue as I can understand (with my limited knowledge). I know my BIOS has the wireless device turned on (Fn + F5 normally works in windows, but in ubuntu I did not notice any changes when I press it).

[chili555]

Ahh! The good old Aironet! Please open a terminal and do:

dmesg | grep -i airo
sudo lshw -C network

Let's see what's happening, or not, under the hood.

and then

hmmm... DISABLED?

[chili555]

Please open a terminal and do:

sudo gedit /etc/modprobe.d/blacklist.conf

Add these lines:

# these aes modules break the airo driver
blacklist padlock-aes
blacklist geode-aes

Proofread, save and close gedit. Reboot and let us know if the wireless now works. If not, please post:

lsmod

Thanks.

[Przemian]

I got it to work. However, I also had to change settings on my router:

went from hidden, no ssid, wpa-psk, channel 1 (2412Mhz) to

open WEP, SSID enabled.

wonder why I couldnt find WPA-PSK encryption when left-clicking on the icon in ubuntu. I only had options of WEP 40 and 128 bit.

Thank you for help

[Przemian]

Also, after the change of router settings, all my other devices on the network (2 laps, iphone and a PS3) get intermittent connection. hhmmmmmm......

[Przemian]

Do I need wpa_supplicant and do I need to edit /user/network/interfaces in 9.10?
Will this interfere with Network Manager?

[chili555]

Do I need wpa_supplicant

Probably so.

sudo apt-get install wpa-supplicant

do I need to edit /user/network/interfaces in 9.10?

It's actually /etc/network/interfaces, and no, you don't need to touch it.

Will this interfere with Network Manager?

interfaces most definitely will.
