unreliable WPA connection with network-manager 0.7

[Aurelien Naldi]

Binary package hint: network-manager

I have weird problems with network-manager 0.7. As I have the same problem on intrepid and hardy (using PPA packages for NM 0.7), I don't think it can be a kernel problem (it works fine on hardy with NM 0.6 and the same hardware/kernel).

Upon connection, it sometimes connects nicely and sometimes fails, prompting several times (can be more than 10) for the password (observed on hardy with one WPA network). Once connected I have many connection loss (one every few minutes), some of them are resumes correctly and some trigger the password prompt again (observed mostly on intrepid on another WPA network but on the same hardware).

Note that I have only acces to WPA networks, so I don't know if it is specific to WPA or not.

This is on a dell laptop with an intel wireless card:
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

I attached an extract on this morning log, I had several connection loss within 20 minutes. I rebooted to an install of hardy (using NM 0.6) on the same hardware and didn't see any loss since (more than one hour ago).

driver bug -> see: 263963

Indeed, it looks similar, but I'm not sure it is "only" a kernel bug: on hardy, using the SAME kernel, the problem is only present if I use network-manager 0.7

well, the iwl3945 drivers really have some strange issues. in hardy we had some scary hacks in NM ... but thats not a solution and also caused issues for others. Have you tried the packages as suggested in the description of the bug?
