Is turning the wifi off when you leave a security concern or a power thing, like you're running off the grid? I'm just curious, as if it's the former and I had the same concern I'd just limit access to specific MAC addresses and make the access point invisible.

Both. Why not save power by turning off the router while shrinking the amount of time there is to break into my Wi-Fi network? I can't see a reason to leave my network on while I'm out of my house. I don't need it and as far as I can tell, my neighbors don't either.

That said if someone needed to use Wi-Fi, I'd be happy to open a guest network for them (I think my router can do that but I haven't checked).

I can understand power concerns (though I think home routers use very little KWH), but frankly shutting your router off every day to prevent intrusions is bordering on tinfoil hat-level of concern.

If you shut off WPS on your router and use WPA2-CCMP with a good passphrase, there is really no concern of someone getting into your wireless network.

>specific MAC addresses and make the access point invisible.

Both of these measures do nothing if any other device is currently connected to the wireless network. A passive attacker will still be able to see your access point (by inspecting packets sent over the air by other devices to the access point) and can spoof a MAC address to connect to it.

Not if you're not at home and hence there are no "other devices" sending packets.
This seems like a rather silly edge case though. What if you accidentally leave a phone or tablet at home and it's sending packets intermittently?

Or what if someone decides to hack you when you are at home?

These are not real security measures.
