If you after a portable router to take with you when you travel you should checkout TP-Link’s Nano Router. The tiny Wireless N Router is powered by a USB charger (which is included) and can be used as an Access Point, Router, Bridge or Repeater. It would be very handy if your using a hotel network via Ethernet and want to connect via a device like an iPad and as it’s powered by a Micro USB cable you don’t even need to carry the charger.
In this video I connect up the router to my network and try it in access point and router mode.
The TP-Link Nano costs £16.99 on Amazon.co.uk
