Hello,

Few weeks ago I connected to new ISP. That's why I decided to adjust wireless interface on router to speed-up.

Unluckily, I got issue with my iPhone. It always disconnects from Mikrotik. I found a lot of messages claiming identical issues between I-devices and Mikrotik. I tried to change "channel width" to 20 MHz, Band to "Only N" etc... Nothing helped!

It supposed to be a major issue for Mikrotik. Unfortunately, noone fixed It or found solution. Let's find solution together. I got jailbreaked iPhone, so I can run tcpdump.

So, what I get every ~10 minutes:

iphone@wlan1: disconnected, received disassoc: sending station leaving (8)
iphone@wlan1: data from unknown device iphone, sent deauth

My config:
CCQ ~ more than 90
