Tools for troubleshooting the network
LAN Under Investigation
Time spent on complex troubleshooting is usually sorely needed elsewhere. Therefore, tools that allow more efficient troubleshooting are always welcome. Network testers promise this efficiency on the LAN, but do they live up to their promises? I looked at two contenders in this field: LanXPLORER [1] and OneTouch AT [2].
LanXPLORER
The basic tests provided by this handy little device by IDEAL Industries (Figure 1) include wire testing. In the setup, you can select different wiring schemas from CAT5e through UTP, CAT 7, STP, and Coax RJ59. One end of the cable is connected with the LanXPLORER and the other to a specific mating component. With this device, you can determine the length of the cable, whether it is broken or improperly connected, and whether there is a short-circuit or cross-talk (Figure 2).
Figure 1: The handy LanXPLORER weighs only 650g and lets you test the basic functions of a local network wherever you are.
