Weighing in at just slightly over one ounce, this little network tool will come in very handy the next time you are installing, upgrading or troubleshooting your network cabling. 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.
