Hello, unfortunately I cannot judge that. We only have one in use (we only had bad reception in one room, rented flat), this one works well, very good reception.

To be honest, range extenders are pretty much nonsense, because you get anything but good WLAN coverage with them. That was and is a mess. The best solution for good WLAN reception is called a WLAN mesh system, which are products that build up a WLAN network among themselves in which you can freely move around and all the devices connected to it select the stronger transmitter in each case, the change between the individual mesh routers takes place without interruption.

This mesh system consists of two high-performance routers that create a very stable WLAN network, which then also provides reception throughout the entire home. If required, up to 10 devices can be added. One Mesh router is placed directly next to the Internet provider router and is connected with the LAN cable, then the WLAN of the Internet provider router is switched off and the second Mesh WLAN router is simply integrated into the network. Each WLAN mesh router also has 3 Gbit Ethernet connections, e.g. for printers or servers or a computer. This set consists of two mesh routers and can even support the very latest WiFi 6.
