Hello all,

I can't solve an issue with my RB751G-2HnD running 6.38.1 (firmware 3.3).
My iPhone 7 (18:XX:XX:XX:XX:E9) and iPad Air 2 are having problems staying connected to my home WiFi.
The worst is my phone, which loses connection frequently and needs to be reconnected manually.
The phone is never more than 12m away, signal strength is usually between -53 to -75.

I searched the forums and saw issues with the country code settings, but setting that did not help.
I also tried running with WPA2 only, no effect.

Below are my settings and logs, I would appreciate any help.

I currently dealing with similar problem. What I understand is that there could quite a few issues wrong.
A: incorrect wireless setup - do not enable any Mikrotik specialities like hw protection etc. / check for correct DHCP setup
B: Are there any other devices like telefonica o2 phones and sh*t like that
C: are those Apple devices correctly configured ? (no power saving modes and stuff like that...)

I will post my solution when it's resolved. But I suspect i'm gonna have to buy some sor of Asus or TP Link router because they don!t have issues. Anyway , best way would be to test it.

As you can see nothing special in wireless settings on Mikrotik.
iPhones are running default wireless settings, issue is not related whether Battery Saver mode is active or not.
Other assorted devices are on the network, as there are three Android phones (which do not have this problem).

I'm well aware of that, but you have to understand that it's cause by some other device in the area. I have this issue only with one klient (samsung devices are disconnecting) and their problems started when they've bought new wireless phones (it may cause interference). My other clients all have 4+ apple devices and don!t have this issue so there's no problem in hAP etc. but there's problem with other devices in the area.

I've tried everything and I don't think there's a magical solution to this. Mikrotik has been ignoring this issue for years now..one would think they'd come up with some sort of solution but so far nothing...nothing at all. My advice to you is to eliminate device that create interference for your Apple devices or just switch to 5GHz.
