Bug Description

Binary package hint: linux-image

System Hardware:

Dell XPS M1330

Ubuntu OS:

Ubuntu 7.10, x86
Linux obiwan 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux

Problem

Intel wireless card 3945ABG, using the restricted driver works fine. At random points after approx minimum of 35 minutes use the connection drops.

On investigation, the card has lost its "wireless extensions".

an "iwconfig" on the card will not reconfigure it.
The card maintains its IP address, routing information.
Dmesg reports no change in the card the interface is still "up", the only points of interest is that the laptop drops from the network and that iwconfig reports no wireless extensions on the card post the drop off.

Rebooting is the only solution I have found to resolve this issue.

I have only logged this bug after confirming no problems with the access point during these connection drops.

Once the connection drops again I will log the output of dmesg, lsmod again

I see the exact same problem on a Lenovo 3000 N200 with the same card

the 2.6.24 kernel has an updated version of this driver and I have had zero drop out since. It would be good if Omer T could also verify this.

It appears the driver update in 2.6.24 Hardy kernel is a large improvment

I haven't seen the problem since upgrading to Hardy. That was a week ago, which is significantly more than what the mean faultless run time used to be.

As we are the only two that has reported and confirmed this bug, and we both confirm that the 2.4.24 release has resolved/massive improvment on this bug I'd suggest closing it to remove developer effort.

The Hardy 2.6.24 Kernel appears to have resolved this bug to an acceptable standard.
