Honey, did you eat my TP-Link mobile router?

LAS VEGAS--You'd better not leave this among the candies, at the risk of swallowing it.

TP-Link showed off at CES 2012 what is arguably the tiniest Wireless-N router yet, called the 150Mbps Wireless N Nano Router (model TL-WR702N). This router is about just the size of a square of white chocolate and looks like one, too.

The router is less than 2.5 inch per side, and less than 0.75 inch deep. Like a smartphone, it uses a tiny Micro-USB port for charging, either via a computer's USB port of a computer or an external charger.

The router has one Ethernet port for connecting to an Internet source, such as a modem or a wired connector at a hotel; after that it offers an instant Wi-Fi network with the top wireless speed of 150Mbps.

Other than working as a router, the TL-WR702N can also be set to work as an access point, a wireless repeater, or a bridge that helps join one Ethernet-ready device to an existing Wi-Fi network.

TP-Link says the 150Mbps Wireless N Nano Router will be available for purchase in the second quarter of the year at an estimated price of just around $40.
