@David-TP 

Thanks for getting back to be (and reading my story).

I would be happy to take any help I can to keep the system that was (when it was working) doing really well.

The main TP is in the basement (Fiber -> Modem (Bell GigaHUB) -> 10GE -> 1.5G port of TP link)

The Second one is in the ground floor (Kitchen) connected via WiFi (I have no way to pull wires in my townhouse)

The Third is one floor up (Bedroom) also connected via WiFi.

I also have a fourth floor where the bedroom floor covers just fine.

Besides the flaky 2.4Ghz connection - being asked to enter password (when a saved one exists) also troubles me as this could be a reason I am not able to re-enter my IoT devices back to any SSID at this pont (those SSID being provided by the TP link system in question).

I am doing some digging on the Leviton Decora units I have as they are the most stable and they offer some logs of what is going in as it tried to connect.

Most of the time - it says unknown error - or sometimes SSID not found.

When I had the IoT SSID enabled, I found that it disappeared very often - only to re-appear a fe seconds later. This was consistent compared to any other SSID in the area.

I hope this can be solved (soon) with a firmware update / patch.

before I forget, I also toggled "Use Mesh" to OFF for all the IoT Devices in the house.

I also Set the preferred Node for them, and even set the 2.4Ghz as the preferred band.

No Fast Roaming was enabled.

Beam Forming was always on - I will try to turn this off and see if there is any change and report back.

Beam Forming on or off does not make any difference (IPV6 On or Off also no difference either)

Also tried the DMZ mode of the modem - no change either - rebooted both router (mesh) and modem to make sure.. no change.

Someone contacted me for a firmware test, however at this point I had to return the system to BestBuy to ensure I could get a refund.

I really liked the Hardware & Software, it had all the features I wanted and was very flexible.

I will keep an eye out to see if the issues in the forum is resolved and re-purchase them again for a 2nd try.

The havoc it created in my home has caused me several days of re-conifugrations of smart devices (some of whom are still not back to normal).

As such there was little choice for me to restore order in the house (4 ppl) where 2 are working from home a lot and the WiFi need to be at 100%.

The 5Ghz (and 6?) seemed to be working well all the time, but the 2.4 was v ery unstable on any SSID..

As for the password rejection for saved networks, this is the first time I have ever seen this.

The support tech suggested I have too many strange characters in my SSID password, or that similar SSID's are in the same vicinity ?

This is a really really strange claim since your mesh system just adds to the existing SSID when you create separate (IoT, 6Ghz) networks.

So by that logic there must be at least 2 similar SSID from the same system.

Furthermore handling special characters (like ! _ @ etc.) is standard practice in strong passwords so if the XE75 Pro cannot handle this, we are in more trouble than initially thought.

Again - I am hoping both these issues are confidently squashed and once done I do not mind trying again.

Hello there

I wanted to reach out and check if you have seen an improvement on your firmware elsewhere?
I am back with the Bell and (Plume) pods for now.

I even tested using the ASUS XT9 mesh (horrible, bad and ugly!) just to see if that was any better.

To be honest, the TP link system was a joy to setup, configure and use.

had it not been for the 2.4Ghz issue I would have kept them - but the IoT SSID issue as well as the constant dropping of connections made me a little worried for the every day critical use of the Home WiFi.

I will keep an eye on the XE75Pro (or its successor), and hope to hear from you with a report that the issues I (and others) saw with dropped connection and 2.4 GHz congestion has been addressed.

I would love to know this as well @David-TP 

Is there another, potentially more stable firmware in the pipeline?

  @David-TP Thanks for the replies, David.

I know my case has been escalated and am waiting for the reply, but can you share anything regarding the builds currently being worked on? Is there any internal feedback? 

Much appreciated.

  @David-TP 

Thanks for the reply, glad to see it is improving and keeping an eye out for more good news.

Is there a difference if the 2.4Ghz devices are on the IoT SSID (locked to a 2.4Ghz setting) or if they are on the "Shared" SSID?

I am planning to buy them again this weekend and give it another go.

I have about 35 devices on the 2.4Ghz from a total of 60 devices where the others are on the 5Ghz (and one on the 6Ghz).

As you can see - more than half of the devices are on the "slower" band.

What is the best approach using the TP links to balance this?

  @Jonas-Homekit That's promising to hear. May I ask which aspects remain unstable?
