Ok. Please help me out TP-link.

I'm getting a bit fed up now.
What hell is happening now?

Please see previous post of my history with the Deco devices and the history: https://community.tp-link.com/en/home/forum/topic/734890?replyId=1468492

 

Just when I thought my problems were finally over, the next problem arrived.

 

Random disconnects to multiple (wifi) devices around the house.

Sometimes the disconnect is a few seconds, other times it can be up to a minute.

 

Fast roaming: On/Off - No difference.

Beamforming: On/Off - No difference.

 

This is the Topology:

I run a main network.
I run an IoT network.
I run a Guest Network.

There are no other DHCP providers on the network.
There are no other network snooping devices that could be of concern.

 

The current IP range is as follows:

Gateway (main deco): 192.168.178.1

DHCP Range: 192.168.176.50 - 192.168.179.250
SubMask: 255.255.252.0 (As per TP-Link default)

 

I've tried everything.
- I changed IP addresses. Went from subnet mask 255.255.255.0 address to 255.255.252.0 address just to see if the extra DHCP IP range space made a difference: It did not.

- I changed around the Main Deco's, swapped Deco positions: It didnt help.

- I Switched between Deco AP and Deco Router mode (Router mode is what I normally use), after I turned off the DMZ from the ISP router of course: It did not help.

- I did a full and complete reset of ALL deco devices. Started from scratch. Set up again ALL of the network, set up the Deco's one by one, let them get their configuration from the main one, reconnected ALL wifi devices. It all took over 2 hours. It all seemed to work fine in those hours. And suddenly POOF, disconnects again. A FULL RESET DID NOT HELP?!

- Changed DNS from ISP provided DNS sources to Cloudflare DNS (1.1.1.1 - 1.0.0.1) - Didnt help.

- Let the app scan for wifi issues: No wifi issues.

- Let the 

 

I scoured the forums here, I scoured on Reddit, I scoured on Google, tech forums. So many people have this issue. So little solutions are provided.

In my Deco main (192.168.178.1) system logs, the following pop-ups frequently and constantly, right before a disconnect happens of a device:

Ping results are stable for 1 to 3 minutes, after that, latency starts to ramp up (moving in to the 1400ms range) before getting a disconnect that can range from just a few seconds to about a minute and after that, ping results come back in normal again. I can provide a screenshot if requested.

The IP stay assigned to the device and is not duplicated somewhere in the network, because that was my previous issue (I believe... But after witnessing all this, I am thinking my first issue was exactly this one as well).

There are SO MANY PEOPLE who have this issue on these forums but not a single working solution has been provided to any of them.
It apparently also started happening to X50 and X60 owners since the latest firmware update. Some people it started really soon, some people it started a few weeks later.

 

Are there any technicians out there who have suggestions? Is it possible to contact someone directly?
Can I go back to an older firmware that worked for MONTHS without issues?!

Please let me know, because after spending so many hours on troubleshooting this all, I am <this> close to send the devices back to the shop and get my money back. Because this is absolutely ridiculous for the price these things cost.
