Monitor bandwidth on personal network [duplicate]
Solution 1:
Since you are looking for something dead simple, I would suggest just installing the network monitoring widgets in windows 7.

This is not the best solution, but in terms of simplicity, can't get much easier than this.
Alternatively I would suggest getting a different router and installing DD-WRT on it. In this scenario you can view a lot of network information directly on the router for all network devices.
