From karmic alpha 4 theres a wireless problem that is in Lucid too with 3945ABG [Golan] Network Connection (rev 02) cards. http://ubuntuforums.org/showthread.php?t=1342897&highlight=iwl3945 People seem to think that card can see networks but not connect because of card is not transmitting anything. And one person told he got things fixed by setting from bios card active from boot. But my bios doesnt have any wireless options so i cant use wireless :S .

At least it's not all cards. My 3945agb works just fine (also did with 9.10).

Are you sure you aren't suffering from the DNS problem?

As cariboo907 just said, you could be having the same problem discussed here.
If so, its easy to fix.

One or two routers dont seem to like working with Linux and its probably worth checking your set up is ok before spending time analysing your OS.
The main problem seems to be a lack of response from the DHCP server. Its worth checking that your router is set to 802.11g only ..or 802.11b only. Sometimes the DHCP server wont play ball if the router is set for 802.11b/g or 802.11g/n.
Once youve done that and if you still arent getting a response its time to look at things a little closer.

My 3945ABG stopped working after the last update and reboot.
But it works on karmic.
So it is definitively a lucid problem.

Just to add another data point: Dell Latitude D830, using Intel 3945ABG WLAN chip: no issues under Alpha1, Alpha2 or Alpha3.

Tryed setting to opendns like shown here http://ubuntuforums.org/showpost.php?p=3996845&postcount=5 . Restarted still couldnt connect to router. Just says preparing to connect and with wicd authenticating.
Router is set 802.11g and tryed 802.11b too. Tryed wep, wpa1, wpa2, without security still same thing.

Perhaps you should try using network manager -- its shown dramatic improvement. 3945ABG works perfectly in lucid on all three of my laptops.

if you mean instead of wicd, default kubuntu network manager then thats tryed and also failed.

And seems like the problem isnt uncommon as http://ubuntuforums.org/showthread.php?t=1417927 slymi2005 says: If I may butt in, what exactly is the difference between the default network manager and wicd? I had constant wireless issues with 9.10 so I upgraded on thursday and I just had my first issue again today. Ubuntu sees my wireless connection but it just won't connect.
And i dont watch forums very often, yet i have stumbled on thread on original post & slymi2005 comment
