My Switch has a terribly bad Wi-Fi range. 1-2 bars in 3 meters away from my router, or any router else. It is a Japanese version of hardware, which is said to be the same as European version. I found it can only support 5Ghz Channel 36,40,44,48 or 2.4Ghz. On my console the signal strength of 2.4Ghz is weaker than 5Ghz. How many people found the same problem?
