I've been having issues with my Deco BE23s. My devices will randomly disconnect from Wi-fi up to 4-5 times per day. My iPhone for instance, disconnects randomly and it won't connect back on until I completely restart my phone. The other solution is to change the Private Wi-Fi Address from "Off" to "Fixed" or vice versa, then it'll reconnect back right away. This also happens to my Macbook after I wake it up from sleep. The Macbook will attempt to reconnect to the Wi-fi but it'll say it's connected and has no internet. The only solution for this is also the same as with the iPhone. 

I've noticed that it's possible that it happens if I move from floor to floor. 

Firmware is updated.

I have 3 Deco BE23.

Operation Mode: Wifi Router (but also had it on AP mode)

Fast Roaming: Disabled

Beamforming: Disabled (also had it enabled)

Channel Width for 5ghz: 160mhz (also tried changing it to 80mhz)

Any help would be greatly appreciated! It's been a frustrating experience.

Thank you!
