My ISP provider provides 2 types of WIFI connection so I have 2 WIFI points available - MyWifi-5G and MyWifi-2.4G
When I connect to 2.4G WIFI, I don't see the issue. But the voice breaks when 5G is connected.
5G is more faster and 2.4G has slower bandwidth. But there is just some difference between GHz that they offer.
So workaround is to connect to 2.4G network when I get into the call.
Let me know if there is something I can do here to fix this and can use 5G as 5G speed is faster.
