I went with Eero and so far it's been great. The app is better and the mesh network has been rock solid. They said it takes an Eero mesh network 24-48 hours to optimize itself for your house, but mine was solid from the start (and our layout is complex). I was probably not going to buy another TP-Link after their slow response to this major issue and then I came across the US government investigation and the possibility of their routers being banned in the US, which convinced me to look at another company for my solution.

It's a flipping joke, sounds like they have school kids on the job.

Things like that shouldnt even better allowed to slip the net.

Does anyone have a good alternative option?

I did think of flashing these with ooenwrt but it's just not quite there to even trial. I want a robust system now.

1.2.1_build_20240925_Beta firmware still doesn't work well with deco app on P9 devices.

Most annoying bugs in Deco P9 firmware:

1. 1.2.1_build_20240925_Beta - firmware has open telnet service without password. Anyone in you net can connect to your Deco P9 using telnet without password.

2. Deco app is unusable. All Deco P9 are offline. You can't add new Deco p9 to an existing network with this firmware. But wi-fi network works. 

3. Smart DHCP feature can't be disabled entirely. Periodically main Deco P9 starts acting as DHCP server. For example if my main internet router (not tp-link) has been rebooted some, devices in the lan may get DHCP lease from Deco P9 which is in AP mode and must not provides IPs to devices.

4. PLC connections are not always stable. Sometimes PLC stops working without any changes to the setup. You can't control PLC connections at all.

5. No diagnostic or any kind of advanced settings in the app or web interface of Deco P9.

6. Wi-fi network become completely unstable if you connect more than 6 (six) Deco P9 access points to one mesh network.It doesn't matter if you connect >6 APs with Ethernet or PLC. After connecting 7th Deco P9 unit to the mesh network, random units became periodically disconnected.

I had the same problem. Beta firmware worked for a few days, then some of the Decos started having VERY slow download/upload (under 1 Mbps) with lots of device disconnects. I work from home, so a stable network is critical. I had to buy new mesh network.

I put all my 4 P9s v2 back to 1.2.1 Build 20240716 Ref 60900 and I had no issues with the app saying that they were off line and everything was bliss compared to the previous issues mentioned.

Then yesterday, my WiFi has been all over the place and my laptop just dropping off the network/apps/RDP freezing on the page and the Android app saying this when I went to see what the issue was.

"Unable to connect to Deco Make sure that the main deco works well. reconnect. alternatively restart the main deco until the LED turns solid green"

Has anyone else had this happen now on this version ?

Can anyone confirm if TPLink are actually looking at this issue to fix ?

I dont want to trial a fix (I did that and it didnt work) as I cant afford for my network to go down but I also cant have this issue that I have currently.

Does anyone have any ideas ?

Thanks

This works great. Had to update the two S4 satellites by IP address, because knocking off the Tapo smart devices had no effect in restoring online status. I have 36 Tapo smart devices connected to the Deco S4 mesh.

  @David-TP 

Which beta firmware should I install for the W7200 and X3600 devices? My mesh network is made up of these and is having this same problem. Thank you.

Hi

Is your P9 network still working ?

I tried to reset my whole P9 network and now seem to be in a worse position as devices wont reconnect as DHCP is not coming through and they cant get an IP address if they are connecting to my slave satelite access points.

What I have leaned

All Satelite P9 v2 devices use power passthrough OK but WiFi is broken as my sons PC works 90% of the time but even that has started to flash red recently more.

As WiFi is broken, devices are not getting DHCP and devices used to work as they had an IP already but on my new network, this was not the case and items like Tado, cant connect unless they are plugged directly to the router.

All slave satelite P9 devices connected all great for about less than 5 minutes when I recreated my network and then went offline.

I will try and upgrade all to beta like you did 1 by 1 on a new network, if this works but reading your posts further on. I dont think it did and you maybe back on an older Firmware

Thanks in advance.

TPLINK - Are you ever going to fix this ?
