Mikrotik HAPAC2 and Tenda AP

I hope I posted this at the right place.

I have a Mikrotik HAPAC2 firmware 6.48.1 as my main router, as soon as I connect a Tenda F9 Router to it in default router mode everything works fine. Except I want the mikrotik to give out IP’s so I change the Tenda to AP mode. But now something weird is happening, the interface restarts every couple of seconds, and this happens at 2 different places and only as soon as the main router is a Mikrotik. When I keep the LAN connection between my pc and the accesspoint plugged in and remove the main link from the mikrotik the AP does not restart the interface. Am I doing something wrong?

I attached the log from the mikrotik.

How are you connected to the internet?

Hi thanks for the reply. The Mikrotik’s internal antenna is to weak for the range so I added the Tenda f9 Router/Access point with 4x6dbi antennas. I tested on another mikrotik and its working there so I presume it must be a configuration error on the HAPAC2.

I added the file as requested.

Kind regards

I suggest you first to all to upgrade to 6.48.3

and paste this on terminal without omit the { } !!!

{
/interface detect-internet
set detect-interface-list=none
/interface bridge
set bridge profile=none
/interface wireless security-profiles
set [ find ] authentication-types=wpa2-psk
/interface wireless
set [ find default-name=wlan1 ] band=2ghz=g/n
}

“as soon as I connect a Tenda F9 Router to it”

on what way, by cable?
i have thow into the recycle bin all the tenda, because on ap-mode sometime turn on dhcp server and on settings don’t are any menu to disable it…
