You can install several Wi-Fi Boosters in your home for better wi-fi coverage.
You can install your Wi-Fi Booster in two ways: star or cascade. The choice depends on the configuration of your home and the location of the b-box.
The star installation is best if your b-box is in a fairly central position in the house: each Wi-Fi Booster will connect directly to the modem via wi-fi.
The cascade installation is better if your b-box is in a more off-center position, for example in the cellar or garage : the second Wi-Fi Booster will connect to the Wi-Fi Booster closer to the modem to repeat its wi-fi signal.
