Bug Description

I have a Netgear WG111(v3) USB dongle, lsusb id is 0846:4260.

The device is configured with a static IP address, and connects to an access point using WEP encryption.
The machine it is connected to is a Dell PC, located under a desk. Normally nobody is logged in via GDM,
network-manager is not running and it is not managing the interface.
The computer collects syslog information sent to it over the wireless interface, at present from only one host.

After a few hours the device disconnects with this message:

Aug 26 18:12:24 ubuntu kernel: [606323.620015] No probe response from AP 00:04:ed:00:00:00 after 500ms, disconnecting.

The interval before disconnection is variable, but usually more than 1 hour.
I have a cron job that stops and starts the interface once per day
$ cat /etc/cron.d/wireless-restart
55 0 * * * root (/sbin/ifdown wlan1; sleep 15; /sbin/ifup wlan1) 1>/dev/null 2>&1

This always works, ie the interface comes up, but it disconnects again after a few hours.

Notes:
The AP MAC address looks bogus but it is in fact ok.

Signal strength is reasonable, according to iwconfig:
iwconfig wlan1
wlan1 IEEE 802.11bg ESSID:"My Net's home"
          Mode:Managed Frequency:2.412 GHz Access Point: 00:04:ED:00:00:00

          Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
          Tx excessive retries:0 Invalid misc:0 Missed beacon:0

/etc/network/interfaces is configured like this:

I am usually running the generic lucid kernel, at present linux-image-2.6.32-24-generic (2.6.32-24.41)
$ uname -a

I've tried this setup for a few days with a mainline build, linux-image-2.6.35-020635rc1-generic.
I see the same behaviour.

The only other thing I have noticed is on ifup I see a message about the wrong country code in syslog

Went back to 2.6.32-22-generic, since that fixed other issues (LP:459732).

I installed linux-image-2.6.32-22-generic (version 2.6.32-22.36) and linux-backports-modules-wireless-2.6.32-33-generic (version 2.6.32-22.13) and rebooted, then selected
this kernel from the grub list.

The same failure occurs, with the same error message.
However I don't see the message about the bogus regulatory domain on this kernel.
So something has changed there. I haven't messed about with 'wireless-crda', the
version installed is 1.12, installed 2010-04-16.

Here's the timeline of associations and disassociations with 2.6.32-22-generic:

Hi Vince,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I omitted to remove the needs-upstream-testing tag, I'm not that
familiar with all the LP functions.

I noted in the bug I that tested with linux-image-2.6.35-020635rc1-generic.
That has the same problems.

I tested again, with linux-image-2.6.32-0206322109-generic_2.6.32-0206322109.201008271507_i386.deb

I tried this for a couple of days. The interface falls over after a few minutes to a few hours.

Here's what dmesg says about the insertion (hot-plug) of the device
with that kernel:

And then I get only these items in dmesg:
[ 1986.324027] [drm] nouveau 0000:01:00.0: Setting dpms mode 1 on vga encoder (output 1)
[ 7582.500014] No probe response from AP 00:04:ed:b9:1c:d7 after 500ms, disconnecting.

After bringing the interface up (again static IP config, WEP encryption)
iwconfig reports this
ubuntu$ sudo iwconfig wlan1

While waiting for a response to the initial report I added a pci-based wireless
card to the system, which reports about -80 dBm vs -50 dBm from the netgear.
Not clear why the difference is so large, they are less than a metre apart,
(not too close, in case of interference).
The pci card antenna is connected fine, the system case is not metal (Dell).

I shut down this interface and started another test with just the netgear.
It failed in exactly the same way as before.

here's dmesg for when the interface comes up:
