Ethernet RJ45 cable is used in many homes and businesses to carry data.
Wireless is also a good option but is prone to errors and the speeds are often much slower compared to Ethernet.
Running Ethernet is also much more secure as data can not be picked up as it can with wireless.
After Ethernet is installed throughout a home or business tracking which cable goes to which room or finding a bad connection can be difficult.
This is a task that is made easy with a good network Ethernet RJ45 cable tester.
