Before the installation of these devices, there were continuous torments with fast Internet - there are a lot of walls in the house, and at 2.4 Hz, interference from neighboring apartments greatly influenced. Now, thanks to these little things, it was possible to optimize the "geography" of WI-FI 5 Hz in the apartment. Perfect solution. Too bad I didn't know about it earlier.
