If there is no way to lay a twisted pair cable to expand the local network (difficult layout, expensive repairs), then these devices can save the situation. The setup is not difficult, the speed is acceptable. Got pros: Possibility to expand the network, incl. wifi, due to the existing electrical wiring and if it is impossible to lay a twisted pair cable. Different cons: On one object there is a bunch of TL-PA4010 + TL-WPA4220 (2 pcs), and periodically both TL-WPA4220 stop distributing wifi - the main router stops seeing them. You have to take them out and insert them into the outlet, then the network appears. Perhaps some conditions of a particular installation site, tk. on a neighboring object, the TL-WPA4220KIT works without problems. Well, the price is great.
