Questions of the Cable Kind

Hi,


This probably sounds silly to you. I'm not sure what cable I should use to connect my cable modem to my Ethernet port. What's it called?

Surely I can't use a crossover cable, right? Do I have to use what is known as a "CAT 5" cable? Or are there other names for it?

What sort of cable should I ask the store clerk for? It's supposed to connect my cable modem to the Ethernet port?

I'd be glad if you could help.

Yes, it's a cat5 rj4 cable, you buy them in different lengths Try Maplins and type Rj4 in the search.

This link will take straight the the type of cable you'll need:

Thanks for all your help. At last I'm clearer.

One thing though. My installer disc mentions that I have to use a "10-Base T Ethernet" cable. Is that the same as the one you all mention?

they are all pretty much talking about the same thing. RJ45 is the name of the specific connector at each end of the cable. also known as a patch lead/cable.

If you are on NTL cable they should have provided you with this RJ45 patch cable when you signed up. I got both the ethernet RJ45 cable and the USB cable. Still have the latter as spare as not used. This one metre RJ45 patch cable is about £7 at PC World or Dixons.

Yes, Seashanty. And I was silly enough to have lost that Ethernet cable :(

The cable modem connected to the Ethernet would run faster. Before I only had one network adapter installed, and that was used to share the Net connection with another computer, so I took the Ethernet cable very lightly. Now I'm regretting my carelessness.

Please could you tell me if I can use any cable listed at click here ?

yep, they'll do the job for you!!

the UTP stands for "un-twisted pair" a description of the individual wires in the cable.

apparently patch cables are on sale at large B&Q warehouses for less than a fiver.

Tedz,

Not sure if you missed a bit out in your description of UTP cable.

UTP is unshielded twisted pair,

STP is shielded twisted pair

FTP is foil shielded twisted pair

If it was un-twisted pair it would not work, the 4 pairs are all twisted at a different number of twists per metre so the 4 prs come into as little contact as possible with each other when made up into the cat 5 cable, this helps prevent X talk between the prs.
