Possible problem with Rosewill RTK-007 LAN Cable Tester

Specs: Windows 7
Hello,

I've never had to use a cable tester before, so I have no experience with them, but I think the one I bought might be defective. I tested two cables, then tested them again a few minutes later and got different results. I don't think it is interference, and it isn't the batteries.

This is the tester I have:
http://www.newegg.com/Product/Produ...

I did the loopback test that the manual shows, and at first, both top and bottom lights matched except for 3 and G, where only the top light lit up. I tested the same cable again, and the bottom lights for 4 and 5 will not come on. Today, the bottom light for two comes on only sometimes. One cable is a 50ft Belkin, and the other is a short flat cable that came with my router.

How can you trust the tester? Call the manufacturer. Ask them what the deal is.

What guapo said.

Considering it's a $15 tool, don't expect much from it.

If you're only making a couple cables for home use, just make them and plug them in. If they work, you did it right. I don't have a tester at home and have made probably a half dozen or more cables at home and never tested any of the ones I made here. They all connect at 1000 Mbps so I know I made them correctly.

If you're going to be making a lot of cables and this is for business purposes, do yourself a favor and spend the several hundred dollars and buy a real tester that certifies as well as tests. I wouldn't trust your tester to be able to tell the difference between a crossover and a regular network cable. If it's for business, you can claim it as an expense on your income tax.

I got a tester because I had read they can save a lot of time, even for someone making cables occassionaly. This one was marked down, and had really good reviews. I did contact the company, and they said to test a different cable or disconnect/reconnect the battery after 30 min to an hour. That did not change anything, so I guess I will return it.

I would take it back and return it too. The same cable should test the same time after time.........regardless of how good your tester is or is not.

From the sounds of it, you don't have to make enough cables to really require the use of a tester. If it makes you feel better to have one, by all means, go for it. The price is low so it's not a big loss purchasing the unit you want.

But to be completely honest, as long as you double check to ensure you have the wires in the correct slots in the RJ-45 end, that the wires go to the very end of the slot and that the cable casing is in the crimp, then you can be pretty sure your cable will work just fine without a tester. I test/certify everything I make at work, but I've never bothered at home. Once I plug it in if the NIC shows its connecting at 1000 Mbps and it works, then I know I made it right.
