@grantlabt I am the latest victim of this setup. wrong info and advertisement. i initially bought 2 decos but I found the 2nd deco not getting enough signal since it is in the 2nd floor. So i got a 3rd deco hoping it would connect to the 2nd deco. Unfortunately, it didn't happen. tsk tsk

Hello all,

This is just to report that the beta firmware works. I have flashed all of my Deco M9 and M5 to the beta firmware given by TP Link support. 

My Deco M5 is now connected to the middle Deco M9 as it should as a proper/real mesh device instead of stubbornly connected to the farthest main Deco M9 with poor signal previously.

Here are the URLs of the beta firmware for those who want to download and test.

M9 V2 beta firmware:

M5 beta firmware (For V1+2+3):

@TP-Link 

I'd like to try the beta firmware for Deco M5.

I made the update with this beta firmware and i still have the same problem. It's super sad that after all this time the mesh is not working how how it should work.

The third mesh connects to the main mesh even if it had a better signal from the second mesh.

It is 04/2021 and this problem is for a looog time :( .

@Silvius Have you ran the Network Optimization from the Deco app?

You need to keep trying running multiple times to make the Deco to try to connect to the signal source you want to. 

Sometimes it works the first try, sometimes it does not and require multiple retries.

Yes, it is frustrating I know. TP Link thought their Deco algorithm is perfect and awesome, but most of the time it sucks so bad.

Which is why many of us are requesting TP Link to give the users the Advanced Option to manually select the signal source on top of their "Auto" Network Optimization.

I have 3 Decos, Main, 2nd floor, 1st floor. 1st floor is the closest to the 2nd floor, but instead, the 1st deco takes the signal from the main deco (the farthest). And there are no options to change the signal source on the app, so the 1st floor speed is so slow. If I could return it, I would.

The option to choose the signal source should have been there in the first place.

Thanks, the M5 firmware works on me. 

What I did:

1. Updated via Web UI

2. Reboot all decos via the app.

3. More > Network Optimization

I hope the source signal wont change to the main deco.

@TP-Link hi, I sent a DM to get the beta firmware link.  Thanks!

@TP-Link Hi! I am facing issues with my Deco M5 slaves (3 pieces) and I'd like to try the beta firmware. Could you please let me know how I can download it? Thank you! Best regards, Alexandre Wada
