I'm not understanding what you're trying to say, is it that you don't get the speed that you're paying for ?
If your router is not password protected then you'll have to find it's ip.
Go to start menu, type "cmd" - open
Type in this command in cmd "ipconfig /all" (space between ipconfig(space)/all)
Look for standard gateway.
When you have found that ip, go to your web browser and type in
http://192.168.xx.xx (example) enter.
Then you should access your router (perhaps you have insert username and password to access it's options)
If not do the same steps but use a network cable from the router to your notebook.
Also be sure to update your atheros wifi card if you have that in your notebook.
EDIT: I don't have the admin options on the router here in my house, since I have to get a cable to access it... but you have to find the "security" and set up a password. Also you should be able to see if others are connected on your internett.
