I want to know how long it can be without suffering from performance loss. And should I make my own or buy a 50foot one from radio shack.

At about 40-45 meters the signal starts to fade some. But the ethernet cable should substain a good signal about a 150m-180m run before you need to start boosting the signal with a repeater.
I don't think there is really any performance difference between a 50 foot cable and a 100 foot cable. And if you are going to buy a cable that big I recommend buying online because other wise your going to be paying a lot.

Actually 20 bucks. Anything beats how slow I am getting wireless right now. ANYTHING!!. It sucks that bad.

get the shealded twister pair not the unshealded twisted pair aswell, as has better signal
Why doesn't someone on here go buy a 300m spool, crimpers and RJ45 connectors and sell them here? I'd buy a pair of 75 footers for sure. Not only could you save the members of OCN a bunch of money, you could probably end up making a little bit of money yourself.

The maximum cat5 cable length is 100 meters or 364ft.

This Guy is right. 100 meters.

Yep 100m is what the IEEE has said the maximum cable length is.

You may get signal further than 100m, but don't expect it to be reliable.

Now, for the next question that I'm sure will come up... How do ISPs communicate between hubs!?

The answer lies in fiber and analog... Coaxial cable, fiber optic are the two most common forms, and they can go many miles before signal degredation.

Wrong

ISP communicate between routers which is connected by serial cable.

would the routers be the junctions or hops you see when checking your connection to a distant server?

Yeah, a hops is when packet goes through a router.

Like a few guys have said before, the maximum length is 100m, but you obviously get a better signal if you stick to shorter distances. And HAYWIREFIVE is right, if you get the shielded pair you'll get less EMI. If you're not sure about making the cable yourself and don't want to go to a place like best buy or radio shack, you could go to a cable manufacturer. I've used allied wire & cable before and they're pretty good. I'm not sure if you're looking to use cat5e or cat 6, but they have spec pages on their website for both http://www.awcwire.com/ProductTOC.aspx?id=Cat5e-Cat6

Its a little less than 150-180 meters. But you are correct.

yeah 50 feet from my router to my pc. and that is alittle more that what is needed. What is the best kind. Or better yet should I get a wireless intel card because I have two dells and they both have intel internet card things and they are extremely fast.
