If my internet service is interrupted by the service provider, can I still access the computers within my workgroup? We are several computers, all running Windows 7 Home, with a mixture of wired and wireless connections.
Yes you can. Your router acts as a hub for the network regardless of whether or not it's connected to the outside world. Remember, though - while you're off the Net your AntiVirus programme isn't being updated so make sure it does as soon as you get back online.
