Strange cable -- what is it?
I have a laptop which I want to use in a library cubicle. The cubicle has a female lan socket and so I went to the store and bought a male-to-male network cable, not looking too hard at the label.
It doesn't work. The computer doesnt see the library's lan.
I also can't use the cable in place of the one I use at home to connect the computer to my adsl modem.
The writing on the cable says
"Enhanced 350MHz PATCH CORD E126126-DG 24AWG 4PR 75degreesC CM(UL) CMG ETL VERIFIED TO EIA/TIA CAT5e STRAND CUSTOM MFD IN CHINA FOR SANWA SUPPLY"
For all the points please try to explain to me
a) what all the abbreviations mean
b) why it doesnt work with the library lan, and what cord would I need to get for that
c) why it doesnt work with my adsl modem and what cord would I need to get for that.
Thanks

You probably need a crossover cable rather than a patch cable.
This will probably resolve the ADSL cable problem, and also the Library.
A patch cable is straight thru,, and is used with a HYB norn\mally.
For other things you need a Crossover cable when directly connecting between 2 devices with no HUB/switch.
CAT 5 E and all the rest are simply standards.
I hope this helps !

should be
a Hub Normally.
The cable is a perfectly normal patch cable, but what you need is a CROSSOVER cable CAT 5.

I was actually going to say the opposite - I think you probably purchased a crossover by mistake and need a normal straight through cable.
If you look at the ends of the cable, a normal patch cable will have all the wires in the same order. A cross-over reverses pins 1 and 3 as well as 2 and 6. If by some strange chance you bought a roll-over, it reverses all 8 - 1 with 8, 2 with 7, and so on.

Hi, thanks for all your help.
I am still extremely confused.
The consensus seems to be that what I need is a straight trough cable, and not a cross-over cable.
The consensus also seems to be that a patch cable is a straight through cable.
But my cable says "patch" on it ..
So doesnt that mean my cable should work? I really have trouble believing that it`s faulty.
Thanks again!

ok sorry I guess I misinterpreted.
scraig is the only one that says I need a straight-through, so I`ll go with the others for now.
Thanks all for doing a great job on explaining.. I`ll buy a crossover cable and ask again if there`s still a problem.

I`m going to try to divide the points between mbruner and sysexpert so stay tuned
Hello all, glebspy has asked Community support to perform a split for two Experts. The slpit will go as follows:
300=mbruner
200=SysExpert
I have lowered the points here to 300 for the first split and have created a question for SysExpert here for 200 points. https://www.experts-exchange.com/jsp/qManageQuestion.jsp?ta=networkgen&qid=20318484
Thanks to all.

hi everyone
I made a mistake .. scraig is right. The patch cable I bought was a crossover and when I replaced it with a straightthrough, the problem was solved. I owe scraig some points. Stand by..

Well, glad you got it working! I thought it would be extremely odd for you to have to use a cross on your library LAN. Also, there are a good number of DSL modems that require straight cables. This is why I figured you had acquired a cross-over by mistake and just needed a standard patch.
On your question regarding if it's good for anything - crossovers are used all the time. Primarily they are used when hooking up two machines directly without a hub or if you want to hook up two hubs or switches without using an uplink port.
