Here’s another great little gadget to have in your travel kit, a wireless router the same size as a USB memory stick!
Configure it once with a unique SSID and password, then plug it into the ethernet cable in your hotel room and it creates your own WiFi network for all your devices. It also works as a WiFi repeater so it will retransmit any wifi you are already connected to.
Much smaller, lighter and cheaper than an Apple Airport Express.
