Wi-Fi in hotel rooms, airports, restaurants and other public areas more often than not sucks, if it exists at all. What you need is a portable signal booster to enhance the network’s reach and signal strength. You can carry around in your pocket while you’re traveling. Just plug it into a power outlet and it connects to the Wi-Fi network and rebroadcasts an enhanced signal. Allows up to 10 devices to access the network simultaneously, and offers download speeds of up to 150 Mbps.
