I have a setup of a Hex RB750Gr3 (7.16.2) and a couple of Unifi UAP AC Pro. The one UAP is connected to a switch that is in ether4 of the hEX, and the other to a switch that is in ether5. Both switches are just dumb ones.
If I have two devices on e.g. the upstairs AP and I move on downstairs for one of the devices to roam to the AP downstairs, I will lose connectivity to the other device - I can see how pinging stops to work. After a little while, seemingly random, connectivity suddenly comes back. I’ve tried with multiple devices and the time it takes varies.
If I connect both APs to the same switch, there are no trouble which is why I suspect the router.
The config of the hEX is pretty default, I see nothing in the bridge or port config that should be causing issues. ARP config etc. is default:
/interface bridge
add comment=defconf name=bridge port-cost-mode=short
/interface list
add comment=defconf name=WAN
add comment=defconf name=LAN
/interface bridge port
add bridge=bridge comment=defconf ingress-filtering=no interface=ether2 internal-path-cost=10 path-cost=10
add bridge=bridge comment=defconf ingress-filtering=no interface=ether3 internal-path-cost=10 path-cost=10
add bridge=bridge comment=defconf ingress-filtering=no interface=ether4 internal-path-cost=10 path-cost=10
add bridge=bridge comment=defconf ingress-filtering=no interface=ether5 internal-path-cost=10 path-cost=10
/ip neighbor discovery-settings
set discover-interface-list=LAN
/interface detect-internet
set detect-interface-list=all
/interface list member
add comment=defconf interface=bridge list=LAN
add comment=defconf interface=ether1 list=WAN
Does anyone have any pointer for what I can try to troubleshoot this?
