What LinkRunner AT Network Auto-Tester customers are saying:

  “I was amazed .. this device was finished testing before I could even explain to one of my junior engineers what I was actually doing. I’ve been an engineer for more than 20 years and this device just gets me, it understands what my workflow truly is and what type of information I need to do my job.” Charles Morris, senior consultant at ACS, A Xerox Company

“After using the LinkRunner AT I can unquestionably say it will save this organization time and money while improving satisfaction. In fact, now that I’ve used it, I wouldn’t want to be without one.” – Thomas Franchina Senior Systems Programmer, United Health Services

“Not only is the LinkRunner AT fast, but it’s incredibly thorough with the essential Ethernet connectivity tests I need. So while it speeds troubleshooting, it also gives me a high level of confidence in the results. If the unit says the connection is okay, I know it’s okay.” – John Heidelberg Network Administrator, Jensen International

"This new tester speeds up troubleshooting as I never would have imagined.... especially for the price! For example you go to a station, plug it in, and in a few seconds you know not only that you have a link up, but you know the switch name that it's connected to, the switch port, the VLAN, etc. This is a huge time saver! Simply tracing a cable that is not labeled... or worse that is labeled wrong, can take hours. But with the LinkRunner AT1000 you know all the details... in a few seconds! I simply love it! Don't leave home without it!"
