If you get an error you might need to do ping -t 192.168.0.1, depends on the make of your router. This will mean the machine always sees that the connection has been active recently and should keep it up. It'll at least help you diagnose the problem.

you can easily determine your router's internal Int IP by going to Start>Run type CMD then press enter
type: ipconfig /all
you will see something like this:

C:\Users\USER>ipconfig /all

Now the part you are concerned about is the areas highlighted in RED

If the first 4 "groups" of Numbers(Called Octets) of the IP address do not match your first four of your Default gateway address you have a network problem.
If they do match, try the Ping as Hoosier stated above Using the address of the Default Gateway.
it will look something like this:
C:\Users\USER>ping -t 192.168.0.1
