Need to upgrade my home wifi

Thank you for your kind reply. But you see, this is where I get lost. I don’t know anything at all about all things “behind the scenes” when talking about Wi-Fi and such. Even less about what you described with making transparent tcp/ip network.
But if this is required, would you be so kind and explain to me how I accomplish this? As you would explain it to a child. :see_no_evil:
