You can use a program called Insight. This program is made by Faronics. It was intended for school use, but I have used it in many differnt applications. Otherwise you could check and see if you can get a router with Web Monitoring.
I need a wireless internet connection, but not thru a router. i want a unit that has a sending transmitter with an ethernet port, and then a reciever with an ethernet port that i can connect to a switch . Does anybody know what these are called?
