[Bug 607064] [NEW] ipw2200 constantly disconnects, /var/log/syslog says ipw200: Firmware error detected. Restarting.

[puff]

Public bug reported:

This appears to be related to bug #352150 and possibly bug #331103, but
the problem still occurs (and much, much more frequently) under Lucid.

I have a thinkpad t43p with ipw2200 wireless.  For several years it has
worked perfectly on unsecured wireless networks.

Recently I set up a home network with WPA2 encryption.  I started seeing
random disconnects every so often.  Most of the time it reconnected and
I restarted ssh, etc, and went on.  Sometimes it did not reconnect at
all.

When I checked the syslog, I saw multiple occurrences of:

     ipw2200: Firmware error detected. Restarting.

I researched the problem and found bug #352150 and others.  The
conclusion seemed to be that it would be fixed in a newer version of the
kernel.  I bore with it and eventually reinstalled my laptop with Lucid.
The problem continued and happens much more frequently, to the point
that most of the time, my wireless is useless.

Previously (pre-Lucid), the connection would stay good for several hours
at a time, or would disconnect and then reconnect every ten or twenty
minutes.  Sometimes it would disconnect and reconnect every couple of
minutes, eventually becoming unable to reconnect at all. Usually at that
point, no matter how many times I retried, I couldn't get a connection.

Sometimes, if I suspended and resumed, it seemed to start working again.

Since reinstalling to Lucid, some days I'm lucky and get 10-20 minutes
of working network, and then it starts disconnecting and reconnecting
constantly, eventually giving up and unable to reconnect for the rest of
the day.

I have had problems, in the past, with ipw2200 not functioning when
resuming from hibernate.  In the past, I found that using modprobe to
remove and reload the ipw2200 module would solve the problem.  I tried
that with this problem, e.g.:

----------------------------------------------------------------------
$ sudo modprobe -r ipw2200
$ sudo modprobe ipw2200
----------------------------------------------------------------------

But it had no visible effect.

In the 352150 comments, somebody suggested creating a file named
/etc/modprobe.d/ipw2200.conf, containing this line:

----------------------------------------------------------------------
options ipw2200 hwcrypto=0
----------------------------------------------------------------------

The comments also suggested using the hwcrypto=0 argument on the
modprobe line, e.g.:

----------------------------------------------------------------------
$ sudo modprobe -r ipw2200
$ sudo modprobe ipw2200 hwcrypto=0
----------------------------------------------------------------------

Neither of these had any visible effect.
