I've spent hours looking for a tool to monitor my LAN network. My router is a TP-LINK TL-WR941N, and it provides a Statistics Page, which seems useful.
ROUTER STATISTICS -> http://i.stack.imgur.com/U9OBl.png
However I need a webtool with some graph (references in KB/MB preferly), user-friendly, that runs through a port, so that every PC has access to it and view the traffic of everyone.
Does anything like this exists?
