Hi
My etherbet cable has been working well since I connected it about 6 months ago but I just got fibre (gigabits network) and now the cable doesn't give me any internet when I use Wi-Fi not he same pc it works and the cable doesn't work on my pc or laptop
For a tester, you don't need both ends in the same place. You plug one end into the remote box and then the other end into the master box. The picture does make it look like it is all one box, but it is 2.
you could use something like this https://www.amazon.ca/Stanz-Network-Cable-Tester-Phone/dp/B01K1DBKN6/ref=sr_1_4?ie=UTF8&qid=1534708648&sr=8-4&keywords=lan+cable+tester
I can't get both ends in the same place because one is in the attic and the other one is in my room but i will change the connectors tonight or tomorrow
