Lion forgets wireless networks on login and waking from sleep

Problem:

Since installing Lion my iMac forgets its preferred wireless networks on login or waking from sleep, forcing me to both select my network and re-enter my password, every time. This problem persists despite two software upgrades and numerous attempts at fixing it myself. Attempted solutions are listed below. Any new ideas, or is it time to just call Lion what it is (a lemon) and demand a refend?

Running:

OS X 10.7.2

27" iMac 3.06 GHz Core 2 Duo

Airport Express 802.11g (software version 6.3)

Attempted Solutions:

- Repaired disk permissions (both with Disk Utility and in Recovery Mode)

- reset Airport Express to factory settings

- deleted all Network system preferences (locations, preferred networks, etc) and recreated them

- deleted com.apple.aif.plist

- set a manual IP address with DHCP

- moved Wi-Fi to the top of the service order list

- added 8.8.8.8 as an additional DNS entry

- Renewed DHCP Lease

iMac, Mac OS X (10.7.2), 3.06 GHz Intel Core 2 Duo

Solved it! (Finally)

It's been months, but just now I decided to try resetting my base station to factory settings and then switching my wireless security to WPA2. I've reset the base station before, but always stuck with WEP, because of the increased compattibility.

But this time, I switched to WPA2, and so far, Lion actually seems to be able to remember my network.

I also changed the name of the network from what I usually call it, so who knows, try that to if you are at the end of your rope with this problem.
