Mike,
Can you access the router interface (a web page) from your other laptops' browsers? If you can, you might not have to reset it.
If you didn't change the default IP address, you can enter 192.168.0.1, or 192.168.1.1 into the browser address bar to access the interface. And if you didn't change the default login userID/password, it could be something like blank/admin (where the UserID is left blank, the password is admin), or admin/admin. BTW, if you misplaced your router's manual, you can usually find it online at the manufacturer's website. The manual will have what the default settings are, including the default IP address and login.
