|By defualt, your router will not allow remote admin access. You will need to hardwire your computer to the router.|
If that still doesn't work, you will need to check the default gateway by opening cmd and typing "ipconfig /all" without the "" and hit enter.
Locate the appropriate adapter in the cmd window and look for the default gateway. Type the address for the default gateway in your browsers address bar and hit enter.
Hope this helps!
