If you rent your house or apartment and can’t make any significant changes, or if you just don’t want to deal with the hassle and expense of running ethernet through your home, there’s a solution that’s far better than any home Wi-Fi networking technology out there. Known as powerline networking, this solution uses the outlets already installed in your home to deliver ethernet data speeds to the furthest corners of your house.

And best of all, you can get started for under $40, thanks to a 43% off deal running right now on Amazon.

The NETGEAR Powerline 500 1-Port Extra Outlet Essentials Edition Starter Kit features two boxes that you plug into the standard outlets in your home. The first gets plugged in near your cable or DSL modem, and it connects to your router via ethernet. The second one can be plugged into any standard outlet in your house, and it also connects to your computer via ethernet.

That’s the entire installation. You’ll now enjoy speeds of up to 500Mbps, and you can encrypt your data with a single push of a button. (And if 500Mbps isn’t fast enough for you, grab the NETGEAR Powerline 1200 + Extra Outlet 1200Mbps model for 11% off at $79.99.)
