Question

Cat5 cable

by Oct 27, 2013 5:55AM PDT

I would like to know what is the difference between these 2 cables. Because i am getting only 1 mbps download (speedtest) with this cable
nbw-1159 cat5 350mhz patch iso/iec 11801 & en 50288 24awgx4p type cmr(ul) cmg e222711 0438ft
With second cable i get 28 mbps
e188601-j type cm 75c 24awg/2prs tia/eia-568-b.2 ll84201 cmg ft4
If it is not the cable what could it be?

To sniff this out

You would check if the pairs were done properly. I'm going to stop here as wire pairs are widely documented on the web and if the pairs are wrong, the speed can suffer.

Sorry but did you check the wire pairs?

Just trying cables isn't going to tell you why it does that. The web is full of articles about proper wire pairs on this cable.

Cat 6
by pgc3 Oct 28, 2013 2:16AM PDT

If you are running all gigabit hardware in the system, you could scrap the Cat 5 and go to Cat 6 cable 10/100/1000 instead fo Cat 5, 10/100, again all hardware must be gigabit capable. I am not saying this is necessarily the panacea to the problem but it might help. You didn't mention what you are using for a modem or router or what type of service you are using so a bit more information could help. Mr. Proffitt does have a point re pairs.

PS. Sorry but beyond pairs. Nod with PGC3
by r. proffitt Forum moderator Oct 28, 2013 2:32AM PDT

At any long length, say over 3 meters I would move to CAT6 as noted by pgc3. I'm still wondering about pairs and distance here but there's so much on the web that I think it's pretty well covered.

Look out for copper clad aluminum

You may find that in some of the cheap stuff. Make sure all wiring is pure copper 24 gauge or better. Also look out for special grounding specs if you don't have grounding where wire terminates. Your terminations for plugs and jacks should all be 586b so look that up if you don't know already. You didn't say to what these cables were connected or how long they were but I'll presume you're well within the maximum length for Cat5e.
