MikroTik + EAP-TLS + Non-Channel 1 / Apple iOS issues

We had some issues with apple devices recently on a new MT using WPA2 and preshared key - might not be the same but...

The preamble mode was important plus the auth types needed to drop any older auth options types as apple seems to only accept the latest versions

We had iphones, macbook airs and some macs not connect 

These were the settings that made everything spring to life as best I recall

ht-basic-mcs=mcs-0,mcs-1,mcs-2,mcs-3,mcs-4,mcs-5,mcs-6,mcs-7 ht-guard-interval=any ht-rxchains=0,1 ht-txchains=0,1
preamble-mode=long proprietary-extensions=post-2.9.25
eap-methods=passthrough group-ciphers=aes-ccm 

Cheers Duncan
