I have a mesh network with Deco X55 units. 
 

Sometimes my iPhone devices will temporarily drop the wifi connection for a minute or two while I am using it. This occurs while I am sitting (not moving around) with a strong wifi signal. 

If I check my iPhone wifi settings when this happens, the phone sees the deco wifi ssid, but it shows a generic IP address for my device (169.xxxxxxxxx). After a few minutes the connection resumes and my device IP address is updated (192.168.xxx.xxx). 

This issue affects every iPhone device in my

home. No other devices are affected. 
 

iPhone settings are:

- private wifi address (private MAC) is OFF

- IP settings (dhcp) is automatic 

Deco settings are:

- router setup

- security is WPA2

- dhcp server is enabled 

- QoS is disabled

- parental controls are disabled

- fast roaming and beam forming are on 

- mesh technology for this device is on

- preferred band is auto
