Ethernet on off switches is a great way to make sure that you never have to reset your router or modem when the power goes out. They’re also handy for quickly turning your network connection back on if it’s been accidentally disconnected.
If you have a gaming computer, Ethernet is the best way to connect it to your high-speed internet connection. The problem is that sometimes you want to turn off your computer or unplug it from the wall power but still leave it connected online. This can be dangerous because if someone hacks into your system while it’s turned off they will get access to all of your data and files which could be very bad for you.
