Default Bug#653141: linux-source-3.1: kernel module ipw2200 has problems with setting the essid for the wireless device

Package: linux-source-3.1
Version: 3.1.5-1
Severity: important

Below is a session to demonstrate the essid-setting-problem. Look out for the
garbled names like 'gÆisQÿJì)ͺ«òûãF|ÂTø3'. The
ipw2200-version from kernel-source-3.0.0 in comparision did not show this
problem. I classify this error as important, because it breaks programs
like wicd-curses. Even more, on bringing the interface down, the essid is not
properly set to 'off', and the device might continously try to autoconnect to
a new ap.

Have you tried booting Linux 3.0 again? This looks like a bug in
userland and not ipw2200 (which is almost unchanged between 3.0 and
3.1).

Why would that happen if it is down?
