Is there a way to improve WiFi streith in my house?
In some places WiFi is realy poor and I can not move my router. Is there some settings I could change to fix that issue?
You can add some Wi-Fi signal repeaters.
get some powerline adapters
If the devices that have poor signal are connected to the 5 ghz switch them to the 2.4 ghz band it will help. 2.4 ghz signal goes better through wall then 5 ghz. If it doesnt help you can buy a signal repeater.
Deactivate the Band steering option and use 2,4ghz. Possible to add Wi-Fi signal extender or The powerline adapter.
My Wi-Fi network is not available in certain areas of my home. How do I fix it? | Fizz
Wi-Fi signal extender could be a good solution if possible to be installed.
