@gumgum im getting intermittent connection problem, my skype call is not stable at all. below is screenshot of me pinging my gateway (deco the router).

​​​​​​​

when using deco app, i can see deco router is getting 500 mbps, but speedtest on my phone which is just 6-7 feet away, im getting 40-50 mbps (connected to wifi6). please do something about, i feel like this is totally unacceptable.

@gumgum

im having the same issue. I just set up this network last night with the three pack deco x20's and I've had several times the network just says "WiFi connection has been lost" on our iPhones!! I have a new Nighthawk cm1200 modem that I replaced about two weeks prior to installing deco's, on purpose so I could rule out an issue with modem stability first. We are on Cox Gigablast and have no issue if any item is hardwire connected to the tp-link 8 port switch that is connected to the main deco.

if this keeps happening I may have to return this because I need a stable up to date network for my kids distance learning and this should not be happening!

I have a similar issue - newer iPhones, with current IOS software, connect to a Version 1.0 Deco X20, have a consistent loss of throughput. The upstream providers modem is an Arris model CM3200A. I have disabled the Private Address feature on the iOS devices with no success. Deco is current, running on 1.5.0 Build 20210121 Rel. 54794.

Any insight is appreciated.

@TP-Link 

IOS devices definitely show this trait more frequently.  The devices are : iPhone 12 Pro, IOS 14.4.2; iPhone 11, IOS 14.4.2;  iPad 7th generation, IOS 14.4.2

The other devices including IOT seem to be fine, but admittedly are not as often checked.

The Deco did not turn red.

I need to understand the impact(s) or turning off the meshing - WHICH IS WHY I BOUGHT THE X20 - as I do not want to give my wife another thing to complain about. If you have ever been with a woman for more than 5 minutes you understand my situation.

@TP-Link 

I went to Deco APP>More>Advanced>Address reservation and selected the Apple devices, so far it does not seem to make a difference.

I could use some clarification on the reference from TP-Link that "(each mobile device has its own switch on the Deco APP and does not affect other devices connected to the Deco); You could only do the test on one device just in case the device does not have good compatibility with the Mesh technology - specifically, need TP-Link to explain the steps needed.

To TP-Link's questions:

1. How often did the IOS device drop the connection, and how did you restore the internet connection, disconnect and connect the Wi-Fi again, or it would come back automatically? Reply : it seems that 2-3 times per hour is a minimum, sometimes the performance is so bad that devices just stay on the AT&T mobility service, and it's much faster / better behaved.  Wired computers in the house do not have this issue.
2. Is your network diagram like ISP-- Arris model CM3200A—main Deco X20---<Wi-Fi Backhaul> the 2^nd and 3^rd Deco X20?  Reply : Correct.  There is no other wifi extender for the same SSID.

I've come across the very same issue.  You cannot revert firmware, which I think is completely stupid, you can with traditional routers, so that didn't work for me either - failure messages.

My wifi has been stable for a week now.  I disabled guest network and 5GHz, only 2.4GHz operating. Anything on ethernet backhaul is stable as well.

Hope this helps in some way.

@TP-Link I still have routine connection drops -- every 2 minutes my connection to the x20 decos drops for 5 seconds before resuming. This makes videeo conferencing very hard. I don't have this problem when I replace the Deco with some older wifi router I have around the house. My decos all have the latest firmware 1.5.0 Build 20210121 Rel. 54794.
