Hi.....
Dear Team...
i have RB951G-2HnD router board with upgraded version v7.4.1. in this router board enable the Wireless mode and assign the ip pool.
All Windows based systems (Desktop & Laptop) and Android Phone are connected to MikroTik Wi-Fi, but Apple Devices (I-Phone & MAC Book) are not connected to MikroTik Wi-Fi.
many times trying to connect the Wi-Fi but still showing same error "Unable to Connect this Network).
need your suggestions.
Thanks

Hi friend , when going to security profiles disable the bottom two.

WPA EAP WPA2 EAP

This runs your wireless network in a "enterprise" level apple devices don't like this.
Should do the trick otherwise I suggest playing around with frequency.

I recommend you check in Advanced > Preamble Mode and the encryption as indicated by @Gh0sTPaPa.

@muk

what u getting on the log?

/system logging action
add name=wlan target=memory

/system logging action
add action=wlan topics=wireless,!debug

what @danielcs suggesting , i was reading about that , would be the one of the solutions, you can play with that , do not ask me what is the difference between short log both, i really cant answer that
