Dear community,
I am seeking your help in debugging a strange issue I have been encountering recently and am trying to pin down.
I can see wireless hosts from other devices connected by cable. But I cannot see the same host from any wireless device. And not even from the ping tool in the router. But sometimes this does work.
My setup:
RT-AC5300 configured as router, serving DHCP, running Merlin 384.11_2
connected to
D-Link DGS1008P switch
connected to
RT-AC68U configured as AP running Merlin 384.11_2
I checked the obvious, AP isolation, which is not enabled on both routers.
Pinging the host from my macbook gives repeating results:
1 x ping: sendto: No route to host
19x ping: sendto: Host is down
and then 6x just Request timeout for icmp_seq without additional message.
and then, as by magic, suddenly the host becomes visible again on ping from my macbook. It remained visible all of the time from a host by cable. Pinging from the router (both through router UI and through ssh) never gives results. At least that was what I though. When I changed the log level to All and pressed apply, suddenly the Ping started working from the router and from the AP.
The behaviour is intermittent, and returns after reboot. Tried that already many times.
Who has an idea as to what could be the cause of this or in what way I could pinpoint the exact cause?
Help!
