MBP Randomly lost keychain information for wireless network..

[advocation]

I was using my mbp at work yesterday, on work's wireless network, no problems, at the end of the day I close the lid, put it in my bag, take it home, about 4 hours later I use it on my wireless home network for abotu 20 minutes. I bring it into work thismorning, and it says that it cant connect, and it has lost the password that was in there.

I try to enter the password again, and it says that its unable to connect. Also, it says that the network is WPA Personal, when in fact the network is WPA2..

Any ideas? Is it a software update from Apple that's screwed it up?

Look around for the Keychain folder on your Mac. I forgot where it is but it automatically backs up your keychain for you so you can restore it should you need to.
