ZTE ZXV10 W300 - settings for multi-user WiFi

[jsha]

I recently reset my ZXV10 (provided by Sonic when I signed up) to "factory settings." When it came back up, it was configured in bridge mode, so that only one computer could be access the WiFi at once. How do I restore the settings it had when it shipped from Sonic, where multiple users are on a single NAT connection?
