Hello, 

I bought this router two and a half months ago.

It was perfectly fine until last week.

Suddenly, I'm facing some issues like it keeps disconnecting during calls like WhatsApp or Messenger and when I'm trying to play online games.

It happens in both bands. I'm using four mobiles with my router. It's irritating to face this kind of issue during important calls.

I already tried every way to solve the issue, like checking the channel overlap by WIFI Analyzer, resetting the channel settings, or resetting the router, but it didn't fix the issue for me. 

I've seen this happen already to lots of people in the TP-Link Community. 

My router is a US version. And I saw on the global and Middle East region websites that you released a new firmware last month. Then why didn't they fix the US version issue and release a new fixed firmware? I'm expecting an early solution. I don't have any TP-Link service centers in my city. So, this is my only hope to solve this problem.

Version: V1.0 (US).
