This Article Applies to:
Deco M4 V1/V2, firmware version 1.5.0
Issue Description/Phenomenon:
Some customers may report that when the internet connection type is PPPoE together with an internet VLAN ID, after updating to the latest firmware 1.5.0 on Deco M4, the Wi-Fi speed slows down and the wireless connection becomes unstable.
Solution:
If you experience the same issue, please install the following beta firmware on your Deco M4, then confirm if the speed and connectivity again.
Deco M4 1.5.0 Build 20210804 Rel. 77124
Note: This modification will be included in the next official firmware, which will be coming soon.
For any other issues starting just after the 1.5.0 firmware upgrade, the above firmware is also worth a try. If that issue could be fixed, please comment below so that we could update this post. While if it is not working, please start a new thread with detailed information about your new issue.

Hi, currently, 6*M4 are on three different firmware, and could you please try to update all of them to the 1.5.0 build20210804.
Since this firmware has not been uploaded to the cloud server, it could not be updated automatically and we might need to manually upload this firmware.
(I also see that you mentioned before you can not update, but since one M4 is on the 0804 firmware already, it is suggested to log in to each Deco's web UI via its IP address and upload the firmware one by one. The IP address of each Deco could be found on the Deco APP.)
As for the poor performance mentioned before, could you please provide more details about it, like constantly dropping the connection or very low speed?
Could you please also send me a picture of the network topology of the whole mesh system?
Thank you very much.

@TP-Link Hi There,
Just wondering will Deco M4 be able to get WPA3 updates in the future and will there be an update to enable direct speedtest from Deco M4 itself and not thru third party like on the apps which will allow direct measurement of ISP Internet Speed.

@TP-Link thanks for sharing the beta firmware. I have two M4R decos and it fixed the download speed, we use Apple devices and the speed on the mbpro (2020) got up to more than 200Mbps on the fast.com website and the mobile devices got from 50Mbps to a sustained 120Mbps.
I tested it on the rest of the smart TVs and also in the cinema room where the main deco is located and all content comes from an Amazon fireTV.
So I can't wait to get the new official update.
Thanks!, you made my day!.
PS. We are adapting our house as I'm in a wheelchair and I thought that I would like to update the setup to the latest home devices, which do you recommend? will the solution pair with the current setup?.
Thanks again :-)

I installed 3 in my parents home and was amazed.
Bought 5 for our own home.
Told my mother in Law to buy 3 for her School.
I'm starting to maybe regret it. Support ain't that great...
