Deco M9 plus wifi connections dropping continuously
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi,
I bought Deco M9 plus 3-pack one month ago and been generally happy with the equipment and its performace, except one thing: the M9 mesh system wifi connections are dropping continuously.
I have following quite standard setup:
- ISP modem (bridged) --eth--> Main DecoM9 (DHCP, NAT) --eth--> Gigabit switch --eth--> 2nd/3rd DecoM9 (both connected directly to the switch).
- The system is set into Router mode and satellite decos connected to main one via ethernet backhaul. I am having both 2,4+5GHz frequencies selected.
- Wired devices: One PC, Mac and TV connected via ethernet to gigabit switch, PS4 to 3rd Deco's ethernet port
- Wireless devices at home: 2 ipads, 4 iphones, AppleTV, two notebooks, etc.
My problem is that the wifi connection drops often unexpectedly and then all wireless devices lose simultaneously internet connection. These devices can be in different places at home. However, all wired devices are having flawless internet connection at the same time so this cannot be an ISP issue. While the wifi connection goes down, the wifi signal strength shows still 100% in the devices. All Decos have green light when this happens, and the wifi/internet connection returns itself back after some time, typically after a couple of minutes. This can happen multiple times per day, sometimes 2-3 times per hour and while everyone at home in the evenings, it can be very frustrating.
The firmware is latest and I have tried changing AP locations, re-booted them, unplugged/plugged from power, etc. but the issue does not go away. I am a bit helpless at the moment. Is there any idea what could be causing this and how to cure to this erratic behavior?
Thank you very much, appreciate any advice on this.

@tau I was having the same problem, (laptop wireless into M9) however I noticed that all of my smart devices (plugs, assistants, lights etc.) were not having any issues. So after some troubleshooting I found that if I manually switched my laptop over to 2.4 ghz it never lost connection. Not really a soltion but I can get my work done now.

I'm having a similar problem.
If a device moves from connecting from one deco to another, or a new device connects (I open the lid on my laptop for example) all the decos turn red and get flakey. this behaviour lasts for a while then stops. Someone already connected seems OK but not all the time. It's very strange.

@tau I have the same issue now.. replaced a Linksys AC1900+ with the Deco M9 (3 pack). The wired drop works perfectly,
I have not seen them lose connectivity. I do however see wireless devices dropping, like during zoom calls.. and my VPN
tunnel drops often during the day.. when before it never did.
I am running the Deco M9 as router Mesh.. I may put the Linksys back as router and try the M9 in AP mode. But it sounds
like the same issue.

@HoRangMo I ended up replacing both my Deco M9+ units under warranty and have no issues now. I suggest you try the same as Tp-Link tech support didn't have any solution besides to replace the units. I can now say that my Deco M9+ are working the way they should be and not dropping at all.

For the record, I wanted to contribute my solution. It looks like one potential drop-out reason is that the Deco system is trying to perform a firmware update in the background, but something is going wrong during this process (commented in this reddit thread: https://www.reddit.com/r/HomeNetworking/comments/hni0ep/deco_m5_connectivity_issues/?utm_source=share&utm_medium=web2x&context=3).
My solution was to power-cycle the modem to reset the wifi, which go me back on the network, after which I manually triggered a firmware update for the deco systems from within the application. If power-cycling the modem doesn't re-enable the wifi, then you may just need to wait for the wifi to come back up to do this.
It hasn't been too long since I did this fix, so I'll add an update if this solution doesn't work long-term.
Best of luck to anyone trying to solve this in the future! Hopefully, Deco will improve the background update processes.

had these about a month and a half. great speeds. Internet dropping constantly on the non-wired to the moden Deco.
the deco conecnted to the modem has no problems with Wifi. The 2 stations loose internet way too much. Laptop shows its connected to the AP just no internet.
Sadly there seems to be no fix other than to return.

Hi, if you would like to spend more time, I would be glad to forward your case to the senior engineers for further assistance.
At the same time, could you please help me check the following information as well:
1. Did your laptop connect to the satellite Deco via Ethernet cable?
2. Would any of the satellite Deco units blink red when the connection dropped?
3.Since there is new firmware available for Deco M9 plus now, could you please try to update the firmware to be the latest firmware first:

Thank you very much and wait for your reply.

I also have this problem, losing the wi-fi when my modem and the original wi-fi remain online. The green light is always green so that does not help diagnosis.
My firmware version is 1.5.1 Build 20210126 Rel 59387
I have 3x Deco M9 Plus v2, the main Deco is connected directly to one of the modem ethernet ports.
This problem makes it impossible to use the system for work as I keep getting cut off in meetings! very frustrating.
