Deco M4 wifi clients with wifi connected and "no internet"
I Have a pack of 2 of deco M4R units, wifi was setup, apparently no issues. The network topology is
WAN - ISP router (bridge port) - deco M4 (1Gbps+ cables all over, all ports are 1Gb).
I have exactly the same setup I had with a tp-link wr1043nd v3, that I have now replaced by the pack of 2 deco M4R.
Just bought 3 new nokia 2.2 (android one 9.0), and already on their setup+updates I noticed that they would drop the connection in the middle and I had to disable/enable the network to keep going with the setup!
Now, to definetely troubleshoot this I reset the decos, created a new fresh network with only one deco (left the other unconfigured and powered off), changed the dns of the WAN to 8.8.8.8 + 8.8.4.4, and disabled fast roaming. Nothing else. My tests are being done within 3 meters of the deco and the ISP router.
I also reset 1 of the nokia 2.2, besides adding the google account, nothing else was changed.
I also enabled the wifi on the ISP router (that I keep off) just for testing and comparison.
I am using the android youtube app for tests, I choose a fullhd or 4k video of more than 20 mins and just play it and see if it goes through all of it.
On the ISP router (I selected my own channel 6 here): no issues, connection always fine, speed fine, video plays all.
On the deco (apparently selected channel 9): issues, deco shows white led all time, other devices seem fine, but these nokia 2.2 the wifi shows connected, apparently no issues, but anything net related does not work (sometimes it will show "connected/no internet"). A disconnect + connect works again for some minutes (around 5-7 mins).
I already tried everything on tplink foruns, even spoke to nokia support to see if they had any wifi compalints (had none), checked nokia 2.2 reviews (also no wifi issues). I also notice that on some samsung tablets, using wifi 2.4 the speed is bad (at 1m from the deco!), starts fine at 50+Mbps but drops fast, eventually the average is listed at 5Mbps? With the older wr1043nd, also 1m away, I had the max wifi speed (120Mbps!), and I also get max using the ISP router.
Testing a laptop PC or samsung tablet on 5.2GHz wifi on deco I also get the max speed.
I also noticed by peeking at the http://192.168.68.1 (default) that the CPU keeps going up to almost 100% for nothing, then returns to decent 4%, this keeps going in a loop, does not look normal... I do not see anything major on the logs, the deco shows nokia 2.2 connected, nokia 2.2 shows wifi connected, but there is no internet at all!
I also changed the nokia 2.2 to use a fixed IP instead of dhcp for the deco wifi, I stil have the same wifi conencted/no internet issue, tryed disable mesh for this device, still issues. Nothing seems to fix it. This would need a good debug on the deco unit ...
This is very annoying, and I need to keep doing disable/enable of the deco network to have stuff working. Connected to the ISP router wifi, no manual changes and no issues whatsoever.
I think there is something wrong with this firmware for the deco M4, that causes severe issues within the 2.4Ghz wifi, causing "some" client disconnections, and I cannot troubleshoot further, if this is not fixed, since the nokias work fine woth other non-deco wifi's, I will have to return the decos since 3 devices at home cannot use it?
Just reset both decos and swapped the roles (always keep only the main on) and the issue is still there, turn on wifi, start a youtube video, after 6:10 it shows buffering issues and I try to open any link, shows disconnected (but wifi shows on, and the deco also shows nokia 2.2 connected).

By the way, I just remember that when I first installed my 3 deco M4, my connection with my miui redmi 6a was just fine. After sometime, I started to have thoose deconnections. May the problem of connection have begun after some firmware update?

@Kevin_Z Defenetely tp-link has major issues with all their software firmware acroos the entire deco/mesh line (just check all the issues on all deco models!) and tp-link just seems to not have the technical/software capabilities to solve this.
tp-link should just provide firmwares with the option with telnet or ssh open, so that people that know something about routers can peek, heck, even try to tune them (even if not re-apllied at next boot), that would help a lot troubleshooting and identifying the issues. In case of an issue/support need, tp-link can always ask the client that if it was tamapered, to do a network reset first, there is no damage risk since only volatile configuration can be changed (and lost between reboots).
I am sure this would speed up identifying issues and, maybe, even providing solution(s) to be incorprated in later firmware releases or temporary workarounds untill a new firmware comes out, providing valuable feedback to tp-link, because most of the casual users would not attempt anything manual on their routers.
I am still waiting for promised configuration settings since 6 months I reported mine here . . .

I am now advising anybody that needs a stable and configurable wifi to stay away from any tp-link deco product, to read the tp-link foruns to make a decent purchase opinion and understand the cabeats of such product, because all deco products are affected by the same major flaw of no manual channel and channeld width selection (bottom or higher product lines).
This shows that there is a major issue with the software development of tp-link with no apparent will to solve it. The hardware is really nice (as some previous routers have shown when flashed with ddwrt or openwrt or similar), but the tp-link own software is never up to it.
This ends any possible relation with any tp-link product ever.

I totally agree!!
tp-link's ability to address the Deco series' software issues appears to be non-existing.
My sincere advise to tp-link is to stop developing new, eye-catching, products - and focus on software improvement of the existing portfolio.
The deco's as per now are basically rubbish, and definitely not up to the standard customers deserve!

Just received my 3 Deco M4 today and got exactly the same problem. It seems that the problem only occurs when my satellite AP is connected through ethernet. Plugging the ethernet cable makes the ping way more stable but induces frequent random packet loss (4 to 8 packets are lost every 4 to 10 packets sent). I measured this through pinging a device on my local network, but the results seems to correlate with what I experience with VoIP (crystal clear voice when satellite is wireless, horrible experience and connection loss when ethernet is connected).
My network configuration :
- My ISP hardware (french ISP "Freebox Mini 4K") is acting as router + provides DHCP
- My main Deco M4 is plugged through Ethernet, configured in AP Mode with 802.11r enabled
- My secondary Deco M4 is connected through another Ethernet port, through a tp-link gigabit switch. I had absolutely no issues before plugging it through ethernet
Tested through Android devices (OnePlus phone, Samsung Tablet), Windows 10 and Linux (Arch), always getting the same result.

Hello all, sorry to respond late.
For those who have encountered the disconnect issue with the Deco M4 network, please help to confirm the following information and we will try to fix it ASAP:
1. Who is your internet service provider? And what is the current network diagram? How do you connect these devices together?
2. Is there any error message on the Deco app when the internet stops working?
3. In the meantime, please connect your laptop to the modem directly and verify whether it is the ISP issue or the Deco itself.
4. Besides, cause the wireless device still connects to the Deco with a valid IP address, at that time, please ping the gateway of the Deco which is 192.168.68.1 by default, and show us the ping result.
5. You are suggested to swap the locations of the Deco units to give it a go.
BTW, here are some suggestions when there is an unstable issue with the Deco network:
What can I do if the internet connection is unstable when connected to the Deco network?
Good days.

@TP-Link_Deco - BULLSH*T, I provided enought info here related to the issues with the nokia 2.2 (that still happens, I had to keep the ISP wifi enabled because when a big update or streaming is needed, the nokia 2.2 connected to the mesh is a no-go), and there was even a ticket open with support... more than 9 months passed and nothing happened... NOTHING said on these foruns will ever change my mind that this time it will be different.

@VCL I actually I don't understand why we as a TP-link customer that bought the M4 Mesh WiFi , we face the problem and we need to help TP-link trouble shooting?
Like this case may not too many person facing, why not TP-link just ask us return it back to TP-link and exchange another new set to us? If after exchange still having same problem then can suggest customer upgrade to another model or get a full refund? So customer will be happy for your service and we all will continue to support TP-link
