Wifi Networks/Settings Backup/Restore

view story

http://androidforums.com – Using Root Explorer, where and what files would I have to get, to backup all of my current Wifi networks/locations/settings I currently have on my phone, before wiping out the phone clean and losing all of that info? A lot of my current saved networks/settings are from other states I saved while traveling, I want to wipe out my phone and redo it, but want to restore all of this info after I do so. Instead of using titanium backup or anything like that, I would rather just find and copy the needed files using root explorer, then restore those files back to the phone later. (General)
