Kubuntu update broke things

[joe at actionline.com]

I hate updates. Almost every time I do an update, something breaks.

This time after doing the latest kubuntu update on my Thinkpad, the
system no longer retains my wireless key password.

Before the update, wireless automatically connected every time I opened
the lid after it was shut and every time I restarted the system after
shutting it down.

Now, after doing the latest update, I have to re-enter the wireless key
password every time I lift the lid.

How can I fix this?
