iPhones (3) and DHCP doesn't work

myconfig_anonim.cfg.rsc (3.31 KB)
Hi,
I’ve recently bought and isntalled the following configuration:
WAN->RB2011UiAS-2HnD->CS106-1G-4P-1S->RBcAPGi-5acD2nD (x2) + HAP AC2.
It took some time and help to configure so my laptops doesn’t disconnect but there is one thing I cannot do. None of my 3 iPhone’s work.
They generally connect to radio (CAPsMan configured) and none of them has a lease in DHCP server.
I can see two problems:

  1. Frequent iPhone MAC@MikroTik-X disconnected, received disassoc: sending station leaving (8) messages
  2. Handshake between iPhones and DHCP server is faulty, it looks like this:
    a) DISCOVER (ciaddr=0.0.0.0),
    b) OFFER (yaiddr=192.168.88.218)
    c) REQUEST (Address-Request=0.0.0.219).
    d) NO ACK
    It looks like iPhone is not using what was offered by DHCP Server.
    Here is my config (attached).

Anyone experienced such problems? Latest FW on all Mikrotik devices.
