I am moving to a house which has in-home wired network. The network runs like this, TV cable from outside comes to family room, I am supposed to connect cable modem and router at family room. There are 2 cables at family room, one has label "Up feed" which connect to upstairs office and the other "Down feed" to basement.
According to the previous owner, he had been using the upstairs office cable till the day he moved out which is just couple days ago and he used the basement cable couple months ago.
Yesterday I used a cable tester to test the cables, but neither up feed nor down feed show connection. I also did swap testing: testing up feed cable at family room with basement cable and down feed with upstairs office, same result, neither shows connection.
I then tested the tester on a short cable, it shows the connection is good. So the tester itself is functional.
So here are all I can think of:
1. The cables suddenly stop working.
2. The tester cannot test long cable; it can only work at short one.
I hope it is #2. The tester I use is from Communication and model is S1007. I googled it but cannot find mentioning any length limit. I actually doubt it is the cable length - even though the cables are behind the walls, I do not know exactly how long they are, I think it is at most 100 feet or so.
I do not have cable company start the service yet, so I cannot test through accessing internet.
Do you have any suggestion if there are something else I can do here?
I'm not familiar with the situation in your country, but when I read "TV cable" I assume, it's a coaxial (RG59) cable. Am I right, or is it indeed some kind of CAT.5 cable (multipole)? I'm asking, because with RG59 the (conducting) cross section is IMHO greater than in CAT.5 cables and length should matter much more in the latter case. Do you use a fresh battery with your tester? – mpy – 2013-05-01T14:58:10.237
