Review on Wireless Logitech MK240 Nano Keyboard 920-008212 with Nano Receiver by Mei Liana ᠌

The first set worked for about 6 years, the keyboard fell off, stopped working altogether. Now I bought a new kit and for some reason it does not receive the signal so confidently, it requires a direct line of sight of the transmitter and a distance of up to 2 meters. But I'm already in another apartment, maybe this is the reason? I sinned on the router, but if you turn it off, nothing changes. In general, it is not clear why there is such a global difference, because in my old apartment I had 3-4 meters from the TV to the sofa, and the transmitter was on the back of the PC and the reception was always perfect.
