[Bug 352150] Re: ipw2200: Firmware error detected. Restarting // randomly disconnecting

[Sergio Machado]

This just happened to me on Ubuntu 10.10 Maverik Beta..

I was using the net for more than 10 hours, made downloads. All was working fine until the wireless connection dropped.
Network manager was trying to bring the connection up again and asked me for the WPA/WPA2 password. The password was correct so I just pressed ok.
What seems weird is that the connection to the router seemed to be established (from the network manager status...)
But it was still trying to connect... and after a while it asked me the WPA/WPA2 password again. And again.. and again...

After right-clicking on the network status icon and removing the check
on "Enable Wireless" and then re-enabling it reconnected to the wireless
network again.

After right-clicking on the network status icon and removing the check
on "Enable Wireless" and then re-enabling it started working fine again:

I have not made any change to modprobe or anything suggested here. I'm
using what comes with Maverick with no changes

It is interesting to see that during the day that message was also
logged but the connection didn't drop:
