The LinkCheck Ethernet Tester gives you a fast readout of the state of your Ethernet connection. Plug it in to your RJ45 socket, whistle aimlessly while buffing your nails, and use the reading to make yourself like an uber geek. Bob Metcalfe? Who he? $39.99.
The LinkCheck can be used to test for the presence and speed of standard RJ45 10Mb or 100Mb Ethernet connections. With the push of a button, the LinkCheck will indicate connection status using three easily readable LEDs located on the face of the device. We suggest you add it immediately to your toolkit and if you don’t, well, then you should probably have your link checked.
