[AFMUG] 2 wireless APs on bridged Mikrotik ports

[Ken Hohhof]

I have a customer who insisted he needed 2 dual band wireless APs 25 feet 
apart in his ranch house.  So we have a managed non-WiFi Mikrotik RB2011 in 
his basement, feeding two Netgear routers in wireless AP mode.  I have the 
LAN ports bridged rather than using the switch chips, since there's plenty 
of CPU power and it gives more visibility into the traffic.

So counting 2.4 GHz and 5 GHz, the customer has 4 SSIDs and I think his 
devices like iPads are jumping back and forth between networks.  And I think 
bad things are happening because the bridging table can't keep track of 
which port the clients are on.  I see weird things like the same amount of 
traffic going out the ports to both wireless APs.  I never see a MAC address 
on both bridge ports, but it is acting like the Mikrotik is flooding traffic 
to both ports.

Should I be tweaking parameters like reducing the ageing time below the 
default 5 minutes?  Should I be using the switch chips and not bridging?

Is this a typical problem when devices can choose between multiple APs close 
together on the same bridged LAN?
