While unorthodox and seemingly complex, the best powerline adapters might be the secret to upgrading your network. These offer a different way of extending your network’s area of coverage. You simply connect one of them via an ethernet cable to your router, plug it into a power outlet, and plug another one in a power outlet wherever you want to have access to that network. 

The best powerline adapters are, therefore, an ideal fix if you’re experiencing obstacles that traditional solutions cannot overcome. They are great for Wi-Fi networks that are unable to reach certain parts of the home or office. Some even have Wi-Fi antennas that allow them to transmit their own Wi-Fi signal.

We’ve collected the best powerline adapters below to help you find the best one for you. One of these might just be the only way to go, especially since their speeds are surprisingly close to wired connections.
