The www connects to the router via cable anyway. World-cable - wall mount - cable - router.
The router connects to devices via cable or Wi-Fi. For exmaple my PC is on cable, my secondary Linux laptop is connected via Wi-Fi, because it is placed away. My smartphone and tablet when at home also connect via Wi-Fi, but could be connected via cable as well.
Wi-Fi switch switches on and off only the cable-free connection from router to device, not from web to router.
I can switch on and off WLAN on the router via a simple button. That does nothing to the conneciton with the www. I cna have even malfunctioning itnernet and route rgetting no signal form the www - while the WIFI still is active.
