Deco M4 WiFi keeps disconnecting intermittently (red LED)
I have a DECO M4R (3 units) connected at the Hall, ground floor room and 1st floor room.
I connect the main DECO M4 to the D-LINK DIR 878. I have been having issues with intermittent disconnecting with red led.(happens on all 3 DECO unit)
When this happens all devices will be disconnected. The SSID for the DECO M4 and the D-LINK are different.
1.I have tried update the Deco to latest firmware.
2. I have tried to move the Deco units by shuffling the location.
Still same issue persist.
Kindly advise how to fix this issue.
Is there any settings I should check?
