I had issue that sometimes whole home network had lags multiple seconds long. I noticed strange activity on all leds on ISP router/modem, Wireshark session found that NX no machine player was flooding broadcasts for local network machines discovery and apparently router tried to forward all those broadcasts to all connected devices in the network, what wouldn't be that bad, until there is some device with weak wifi connection that cannot receive them fast enough. some queue on the router filled up, and router stopped routing anything untill it delivered some of those broadcasts to everyone
