Repeaters can amplify several WiFi signals, such as three WiFi in my house, and whether the three signals will be very good!
The principle is that they will relay transmit a signal, when you connect the log switch relay mode (some repeaters used to relay more than) you can find yourself in the emission signal routing in the WiFi list, after the connection (can also name and password) is forwarded to the original signal, so as to realize the signal extended to enhance.
No, the repeater can only amplify one route WiFi at the same time
