WiFi has to do with the modem and router, not Windows. In the US the lower 2G versus the 5G on your router - I'm told the 2G reaches further but in a relatively close environment, the quality of 5 is better. I set up an Ethernet switch at the back of the house to strengthen the signal and so my next door neighbor can reach it if need be. She would use the 2G for the distance, but around the house I connect to the 5G signal.
