Wi-Fi speed drops down after updating Deco M4 to the latest 1.5.0 firmware
2021-08-08 18:21:22
Model: Deco M4
Hardware Version: V2
Firmware Version: 1.5.0 build 20210804 Rel. 77124

Hi,

So the original problem is described here https://community.tp-link.com/en/home/forum/topic/270556?page=1

 

I have installed the proposed fix as described here https://community.tp-link.com/en/home/forum/topic/272384 but it didnt help. 

 

 

The problem still exists, I m facing huge package lost while I am connected to the main deco. Full reboot helps on a short time but then the problem appears again. I am not able to use decos at all I am constantly tethering the internet from my mobile phone. TP-Link team, I need to understand if you are going to provide a normal fix within a short period of time otherwise I will need to complain to the local seller and return the decos.

Hi, Thanks for the update.

I would like to forward your case to the senior engineers for further help.

And according to the engineer’s request, could you please help me check the following information:

1. Who is your internet service provider?

2.is your internet connection type PPPoE+ VLAN or something else?

 

Thank you very much.
