Hi

I have ×2 Deco M5, the main one is sitting in the living room and the slave in the kitchen. Connection of the slave to the main is good (2/3 bars). 

My house is 1 floor condominium. Refer to attached image of my floor plan. 

During speed test the speed is extremely well. Using mobiles and pc to browse and steaming is smooth. 

However during fast paced online games like Counter Strike & Valorant, there will be sudden ping spike every few minutes and it is frustrating to play. I believe this is called sudden packet loss? 

My pc is connected via WiFi. 

I have read some threads here and on Reddit, seems like it's a problem that is still happening for quite some time since last year. 

My deco Settings:

Operation mode: Router mode

Fast roaming: Off

Beamfoaming: Off

Connected client (My pc) Mesh: Off

Anti virus: All Off

Is there a fix to this? A workaround perhaps? 

When will TP-Link fix this problem with an update? Spent my saving on the Deco M5 and I can't even play an online FPS game...
