Hi guys,

Recently I have rewired my house FTTH cuz the wireman fked up my fiber optic. Modem and router relocated tfrom kitchen to living hall TV cabinet.

Plan: 30mbps maxis fiber
Moidem: Huawei (forgot model)
Router Archer C5V
Package: Maxis 30mbps
Mesh: 2 unit Tplink DECO M4 at 2nd floor

First day after relocate connection is ok. At second day started to DC randomly in the afternoon/ evening when most of us is using internet. We mostly use mesh wifi. I initially thought the problem is ethernet cable connect router to Deco. Previous is using CAT5e patch cord next to router . Now at living hall I have ethernet cable connect to 2nd floor. Speedtest using mesh is around 27mbps download, don't seem to be the issue. The problem is got wifi signal, no Internet. Watching Youtube suddenly buffering. Around 1~ minute connect back.

I read from old thread 2018 many people complain AC1200 is rubbish. After 2 years this problem still persist?

The problem was not coming from the fiber optic. It was the Deco M4. After I switched Deco place also need to change the setting in the app. I thought it was unnecessary at first but little bit does affect.

I actually want to use Archer C5v for wired connection and 2 Decos as mesh. Well...
