Routers are box-like devices, with varying aesthetic value, that use antennas to provide web connectivity by exploiting the principles of electromagnetism.
They are, sadly, also a bit complicated to install, and they aren't always easy to take along on a trip.
TP-LINK decided to make a router specially designed for travelers: the 300 Mbps TL-WR810N.
Basically, it is a small device that gets plugged into a power socket and voila, instant Wi-Fi for everyone.
It can even work in AP mode (access point) and has two 100 Mbps Ethernet ports.
A USB port is included as well, for device recharging.
TP-Link will ship the TL-WR810N from the second quarter onward (Q2 2013) at an unspecified price. Security is ensured by pre-encryption (users from outside the network will always be denied access).
