HOW TO – Homemade network connectivity tester

Jachin writes – “I made a pocket sized network connectivity tester out of an old Network Interface Card (NIC), Wake On LAN (WOL) cable, and a Cheap-O Computer Clock 3X “AA” Alkaline Battery Holder. No soldering required. Our school district can not afford to liven every port in a school. As a computer technician I always need to know which LAN drops are live without lugging around a laptop or searching for the IDF.” [via] – Link.
