it reminds me of the first time i enabled vlans on my switches.
if i understand correctly
igc1 (LAN) is linked to port4 of the switch
igc2 (VLAN11+VLAN22) is linked to port 5 of the switch.
port 4 needs to be set to access mode with PVID 1
port 5 needs to be set to trunk with vlan tag 11&22
but for this to work port5 can't have PVID 1.
I fixed things by creating a dummy vlan 99 (or whatever you want but not used ) and setting PVID 99 to port5.
and of course the port for the orbi needs pvid 1 and tagged vlan11 and vlan22 (if you have wifi cams)
