Bandwidth Monitor 2 Lite Edition
Wondering which PC on your network is using all the bandwidth? You can find out with this exceptionally easy-to-use free utility. Simply install Bandwidth Monitor 2 Lite on any PC, and it then displays bandwidth use in a chart that details your bandwidth use in real time. It displays download bandwidth being used, upload bandwidth being used, and total used. In addition, it keeps logs of your bandwidth use, so you can have a historical record as well.
It's simple to customize the Bandwidth Monitor 2 Lite. You can change its skin, alter the time span over which it measures bandwidth, and more. Note that setting up the software might be confusing, because you'll have to choose from a long list of network adapters, all of which may or may not be on your system. Your best bet is to click the Auto-Select button. The software will then automatically choose the proper adapter.
