0. Say What? Need more information.
1. Area. I don't know what this is, where it would be stored, or how it would be changed. Some Microsoft operating systems have "Regional" settings...?
a. Is this a "setting" within the router or operating system?
b. Is it changing your "language", "location", or both?
c. Where do you see the "area" reported?
2. Router.
a. Is this a home router or commercial grade (industrial strength)?
b. What is the make, model name, model number, and hardware version number? Report whatever is on the identification plate on the back or bottom of a home router. No idea where it would be on a "commercial" router.
3. Operating System. Which one and service pack level; e.g. Windows XP Home Edition SP3?
