Deco M5 Constant Short term Disconnects for Wireless Devices
I have a mesh of 6 M5s set up in access point mode. The set up is just over a year old and up to last month very reliable. I have about 80 wireless devices on the network mainly low bandwidth IoT devices. This is under 50% of the stated max number of attached devices.
In December I noticed that some of my IoT devices were dropping their wi-fi connection. After trouble shooting I decided to replace my old Mikrotik router and TP-Link switch with new Mikrotik equipment. For a week everything was good. However I am now experiencing the same rapid dissconnection/re-connection of all wireless devices. The situation is so bad we have had to hard wire TV and laptops idf we need to stream media.
I have attached an image of a wi-fi switch showing the constant disconnection of the device from the network.
All devices, of all different types, brands and 2.4Ghz/5Ghz all around the house are effected.
I have read numerous community posts about people having similar problems so I have downgraded and upgraded the firmware to all available releases, factory reset all Decos and re-created the networks (I use 5Ghz as main and 2,4Ghz for all IoT equipment), changed the main Deco for another, removed the old main Deco from the network (in case that one unit was faulty) .
I have checked for wireless interference from neighbours and there is no other wi-fi signal on the premises. I do run a Zigbee mesh on Zigbee channel 11 but this has been there when the wi-fi network was running OK.
In addition
- CPU usage on the Decos is low.
- Switching off Fast Roaming / beamforming / IPMG has no effect
- I have switched off roaming on the IoT devices but they still disconnect as frequent
Questions:
1) what tests can I run to find out if one or more of the Deco units is faulty
2) what other suggestions do you have to correct the problem is all units appear to be OK?
Thanks in advance.
