This is a shot in the dark, but figured I'd ask. Is there any type of firmware that can be installed on the modem to monitor device usage? I have intermittent issues where TV begins to lag, and although I can see which devices are connected, I'd like to have visibility on actual device usage seeing as I see spikes on bandwidth usage, but I have no idea which devices could be causing it.
I've gone through the whole process of elimination as well with connecting one device at a time, but the pattern isn't consistent so when it happens I'd like a real-time view of which device could be hogging all the bandwidth on my home network.
Any tools / utilities out there that can be installed directly on the modem or PC?
