UDP Broadcasts from SSID-2.4G to SSID-5G do not travers.

I am having issues with bonjour protocols, if my Wifi Printer is on the 2.4G network and my laptop is on the 5G then I will not see the discovery packets of bonjour.  (I think another name for this is dns-sd)

 

is there something about the SSIDs having to be the same for both 2.4 and 5G ssids?

Is there netmask that is blocking the UDP Broastcasts?

 

 Hardwired and Wifi are all on the same vlan..

 

Help?

    This would be a bug if true. Is this on the "normal" or on the "guest" network? Firmware version?

    Absolutley not - the LAN port and all WiFi SSIDs connect to the very same broadcast domain and IP subnet.

    Just in case - double check all systems involved (printer, computer, mobile) are configured to the exact IP subnet, with the appropriate subnet mask. Systems getting the IP network config from the router DHCP server should not have a problem anyway.

      This would be on the normal network.  Firmware V1.0.3.88_1.0.41

      all IP addresses  begin with 192.168.1.*.
      Subnetmask in Internet Port is 255.255.252.0

       

      And... the software just asked for a firmware update. :) lol
