wireless connection drops. Network manager show continued connection

[deibhaid]

In Intrepid Ibex (Stable), My wireless network connection is unstable. My laptop has a weak connection to the router, but this was never an issue before in hardy heron. The connection appears to be still connected when I glance at the NetworkManager Applet, but I cannot ping outside networks.
Performing an ifdown eth1 and ifup eth1 repairs the connection.
dmesg shows this message:
[122696.974396] ipw2200: Failed to send SSID: Command timed out.
[122698.530261] ipw2200: Firmware error detected. Restarting.

I have this behaviour too. I'm also running Intrepid and I also have an ipw2200. First, I have a connection with works, but after a couple of minutes the connection drops although the applet shows a connection.
To clarify: I only connect to two networks: at home (WPA-PSK, works ok as the strength of the signal is very high) and at my university. Here, this behaviour occurs The network has the following characteristics:
- a lot of acces points with the same name and security throughout the building
- security: WPA2 entrepise with EAP TTLS (PAP)

ifdown and ifup do no work (my network card is named eth1):
sudo ifdown eth1: ifdown: interface eth1 not configured
sudo ifup eth1: Ignoring unknown interface eth1=eth1

Also, dmesg|grep ipw2200 does not reveal errors.

Hopefully, I can help to fix this bug.

Is this still an issue for both of you? If so, could you take a look at this bug report I filed:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/303802

and try some of the things Leann Ogasawara has mentioned? It appears we may have the same issue, and I really want to get to the bottom of it all. No suggestions have worked for me, and so I'd be curious to see if any worked for either of you.
