If your phone is rooted you can install an app to do it, look at the app market.

Otherwise, if you are a developer or have the ADT environment setup, you can try to plug the phone to your PC, and from the android file browser retrieve the file:

/data/misc/wifi/ and look for one of the files:

wpa_supplicant.conf
wep_supplicant.conf

For ADT info, look here:

Thanks.

Device it's not currently "rooted".  If I root the device now will that maintain the files you mention or would they be lost?

Rooting only means gaining complete access to the device for applications, that's why some apps need "root" access to be able to read or modify OS files. This will invalidate your warranty however, and make you more prone to be attacked by a virus and other malware.
But you will keep the files, rooting does not affect the OS files.

You can do it all from a PC with Android Development Toolkit, which is what we use to write android apps, and gain developers access to the mobile phones.

Are you sure, it's not better to get the passwords from their proper places?

This page suggests files would be lost if I understand it correctly.  Is that right?

There are different methods to gain root access to a phone, some are destructive, and some are not.

Replacing the rom for an unrooted one will obviously format the phone from scratch. The options that the manufacturers give are not always the best, as they are not interested in people rooting their phones.
