Extending multiple SSID with CAP

hAP AC is not the same as hAP AC2

2 different devices.

Just an update.
Found some time today and after some successful testing on a hex RB I took the plunge and changed my config on the hAP AC as per the guide at http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/1

So I now have VLAN set ready for the next step to create a trunk port to an AP.

As expected CPU utilization is now much higher. 1 client at 90Mbps download causes around 80% CPU. Add in another downloading client and it is up to 100%.

Thanks for all the help.
