Disconnected due to excessive missing ACKs

Issue: Wifi problems with Android / iOS devices:

  1. constant disconnects
  2. logfile shows disconnected due to excessive missing ACKs

Example log: 

Mon Dec 25 17:28:25 2017 daemon.info hostapd: wlan0: STA 00:00:00:00:00:00 IEEE 802.11: disconnected due to excessive missing ACKs
Mon Dec 25 17:28:28 2017 daemon.info hostapd: wlan0: STA 00:00:00:00:00:00 IEEE 802.11: authenticated
Mon Dec 25 17:28:28 2017 daemon.info hostapd: wlan0: STA 00:00:00:00:00:00 IEEE 802.11: associated (aid 6)

Root cause:

Solution: /etc/config/wireless → @ config wifi-iface → add option disassoc_low_ack '0'
