This all looks good.
I forgot however to ask you to check rfkill again.
I still think the problem might be in the wicd and wpa_supplicant

http://linux.die.net/man/8/wicd
http://linux.die.net/man/8/wpa_supplicant

According docs there is/are log file(s) in /var/log/wicd

Some cards (via bios setting) would disable the card when you have the cable
plugged to your network card, but I think in your case it is not true.

I would backup all wicd and purge - check config etc files are not present,
install again.

Also you shouldn't have any /etc/wpa_supplicant.conf file or entry
in /etc/network/interfaces.

Some Gentoo people had similar issues after upgrade but the wicd is 1.7.1
there https://forums.gentoo.org/viewtopic-t-914678-start-0.html

Lets doublecheck if all requried is install

I've been using the ipw2200 for few years on one siemens-fujitsu notebook
with out issues. There was first debian and then ubuntu on it. Strange that
you can not suddenly connect.
Perhaps you can try with a live ubuntu just to see if it works
