A client on our lan was uploading a lot, and despite pleas then warnings, he did not stop uploading, so we put bandwidth caps on his static IP. We have a near-new Tomato-flashed Asus router.
Suddenly the other clients on the Lan are getting spotty connections.
Could he be using Ping from his computer to interfere with our other clients (the ones who complained about him, maybe it's revenge on his part) ?
Because in the log I notice his machine is constantly broadcasting a message to all other clients on our lan — the QoS->View Details entries look like this:
Proto Source S Port Destination D Port Class Rule Bytes Out Bytes In
UDP 192.168.1.3 53838 192.168.1.255 1947 Unclassified 68 0
You'll notice the 'Destination D Port' is 192.168.1.255, which is how one client on the Lan broadcasts to all other clients on that Lan.
Could this user on our Lan be broadcasting something to interfere with the others users on the Lan?
