Network manager forgets wireless network key

Every time my computer logs out from inactivity, I have to enter the network key for my wireless network. I don't see any "remember" checkbox. Is there a way to get Ubuntu to remember the network key? It seems to remember the networks and which one is preferred etc. This started when I upgraded to 11.10; it had worked properly prior to upgrading.

Solution 1:

Click on the network icon in the panel and choose Edit connections... Go to the wireless tab, select your network and click edit. On the Wireless security tab, make sure the password field isn't empty.

Solution 2:

There is a bug report about this problem: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/877803

Does anyone know a workaround?
