On my network there are several devices (none of which are mine), which do not broadcast a hostname, and instead are labelled “Unknown Device - 4” or similar. I’m not sure if these devices are broadcasting no hostname or just one which cannot be understood by the router upstream. Is there any way I can obtain this behaviour on my AR750S?
I’ve found a way to obtain this behaviour. In case anyone else is trying to do this the method was to set the hostname to be a space, which I achieved through the terminal commands
uci set network.wan.hostname=' ' uci commit network
and then restarting the WAN interface.
