Hi Dave, perhaps you have better results by using the 5 GHz band, if available from your router, or a different channel in 2.4 GHz. The command “netsh wlan show interfaces” can tell you the channel being used so you can change it on the router interface as needed.
It is also possible that other devices transmitting in the same frequency can be interfering with the signal, if so try moving them away from the place the computer is located.
