No idea to be honest, see what options you get when you are logged into the router.
That's great. Huge thanks for the pointer.
I've turned remote management on now. Apologies as I think this is a silly question, but is disabling the WiFi remotely now as simple as clicking the "none" option from "everyone"?
Edit: no, I tried that. It said I can't as it needs at least 1 protocol.
I just want to turn the home WiFi off while I'm at work.
Do not underestimate the ability of a teenager to figure out a workaround.
What you need is Mac address filtering based on the time. That will effectively block internet access to the X box on a schedule either wired, wireless or through a separate wireless access point.
You will need to look at the settings in the now router for this if it supports it (my router has this and other functions that can be used to control access)
Odds on that the teenager will figure out how to turn on the wifi, or even get hold of a device ( ie wifi access point) that will over ride the wifi on/off settings, the wifi may be off but the ethernet will be active.
Turing the router off will/may cause issues with DLM and cause your speeds to drop
Plus its another thing to try and remember.
If you enable mac address timing then you can restrict certain items to set times, so the X box will not be able to connect between X and Y but another device will still be able to connect.
You will also need to change the router config password
Turing the wifi off on its own shouldnt cause any issues, however turning off the entire router will/could cause issues.
As for the Wifi, try looking for a setting called Wifi Schedule where you can set the times the wifi is on/off - not all routers may have this though
