Intel wireless cannot connect using WPA

[resplin]

Just upgraded to Kabuntu Karmic Alpha 6
lspci says: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Kernel module iwl3945 is loaded

I can't connect to my WPA enable access point. It lets me select the access point, and tries to connect, but it repeatedly asks for my password.

It worked with KNetworkManager in KDE 3.5. Wicd works fine.

Hi,

Could you please provide the system log and as many other details about your connection as described here? http://userbase.kde.org/NetworkManagement#Reporting_Bugs (You won't have to give distro version, though :P)

Thanks in advance.

Same problem here using Ubuntu karmic 9.10.
In jaunty it worked fine with same hardware. I think there's some problem with WPA, because it works when I turn encryption off on AP.

Package: network-manager

Hardware is a HP Compaq 6820s laptop - details and logs in attached file...

I seem to be able to connect to a WPA-secured wireless LAN without issues. Arguably, it is secured with WPA2.

Using the same versions; and linux-image-2.6.31-11-generic 2.6.11-11.36.

Could you please verify the version of the kernel you are using, and make sure your system is fully up to date.

System is fully upgraded. Strange thing is that 'wicd' works fine with this network, and previous distro version on 'network-manager' also worked fine...

After some investigation I got this network working - changing from WPA(TKIP) to WPA2(AES) solved problem for me.
Now network is working fine, but it just won't work with TKIP. This might be Access Point issue - it's just low-budget Planet AP.

I experience the same problem. All the APs set to WPA-TKIP are problematic. I am only able to connect to those being set to WPA2-AES. My PC is Thinkpad T60 with Intel 3945. I am running fully updated Karmic Final.

[blackjam (blackjam)]

One more observation - when I try to connect to TKIP secured AP, I actually kick-off the other users of that AP off the net... This has been already described in other bug reports... Very strange.

I just found out a solution to this problem, I was having the same issue and the solution is very easy, common sense, and practical...........SWITCH TO WINDOWS OR EVEN OSX, IT WORKS MUCH MUCH MUCH BETTER!!!!!!!!!!!!

I was the original reporter. This bug is fixed for me in Lucid Lynx.
