Hello all,

A Wireshark capture shows the Archer C2300 router sends a unicast arp request for each connected device every 10 seconds. I am guessing this is a probe to check if each device is alive. Why can the router not cache longer?

Also, the same router is sending udp/137 Netbios name queries for the same PC every 10 seconds. Netbios is disabled on the PC so it will never respond.

The firmware was just updated to 1.0.3 without resolution. Does anyone know how change these settings?

Thank you.
