Network Kill-Switch

[Adrian-Grimm]

As addition to the WLAN and Airplane toggle in the sidebar: A Kill-Switch for all Network-Connections for Internet, WAN and LAN (Ethernet, WLAN, Mobile/LTE/UMTS,...)

If I made add to this, if you are using the built in VPN app inside of Windows 10 could we have that also shut off along with drivers itself? I could see this solution helping with battery life items and performance. I know I wished a couple of times while working essentially offline I would have turned all networking (Maybe other then bluetooth) off to save battery.

trying to better understand the exact ask here.

• mobile and Wifi you'd want to be able to toggle off?
• All network connections [lets say you were on a dock as well] (not bluetooth)
• all network connections [wifi, mobile, wired, bluetooth ...]

[Adrian-Grimm]

With that "Network Kill-Switch" -toggle all Internet, WAN and LAN Connections should be shut-down.
Would be perfect to have such an toggle here:

I don't know what's the best way to achive this, but maybe to disable all NIC's is also a good approach to save battery during that time like @vexvoltage mentioned.

@Adrian-Grimm, do you have data to prove that disabling the network saves enough battery to really make a difference? screen and processor are the big usage. And if you're hitting network, I would imagine, as a user, you are proactively deciding you need to use the network, regardless of streaming or surfing or getting some NPM packages.

@Adrian-Grimm What about bluetooth, you can connect to devices. I'm reading this as

all network connections [wifi, mobile, wired, bluetooth ...]

[Adrian-Grimm]

@crutkas, no - I think that will make no big difference in terms of battery consumption, but it could save a small portion.
The main idea behind this is to cut everything off - no network data out and in.
In Terms of bluetooth we have a separated toggle for that and bluetooth has HID connections like mice, keyboard, ...
But if there is a way to also only turn off any tethering over bluetooth this would be perfect.

As a fallback approach all IP (UDP/TCP/ICMP) incoming and outgoing connections could be blocked through the os firewall - when the toggle is active. This could then have an extended mode where only one or a few applications are allowed to use connections (save data plan...)

Usage for this:

• sometimes you don't trust a Application during execution time..
• as a developer you may want to test how a application behaves in terms of connection interrupts
• you detect some strange activity and want to be sure no remote controlled things happen

There is already airplane mode.

There is already airplane mode.

But this will not turn off Ethernet over cable connections...
