Right now I have my PS2 and TV right by my router which is on my computer desk. I want to move my TV on the other side of the room so I can have some more space. Right now I have a 6 ft CAT5 cord plugged in my PS2 but if I move my TV I will need to get a 25 ft cord. I just wanted to know if there would be any lag or any difference. I heard many people who use longer cords it can cause lag. Its not getting the connection because theres a delay? I've never used a cord longer then 6 ft. I just wanted to know if there would be much of a difference. This might not be in the right place. Thank you.

If you buy the cabling, there will be no difference.

I would wager that the people with more "lag" after adding a longer cable made it themselves, and the lag was caused by a funky, poorly made, not-to-spec cable.

On a "normal" well-made cable, there should absolutely no difference.

Good Luck

The signal through a cat5 cable travels at roughly 2/3 the speed of light. You would need a cable seveal hundreds of thosands of miles long before you would get any lag.

I agree with ScottMac, if the cable is poorly made, it might be causing errors that result in the system constantly resending the data, giving you a lag effect. But even at 25 feet, you have to have a REALLY awful cable to get any problems. I've used poorly crimpted cables that were 100 feet long without problems.

Cool. Thanks for all the replys. Im going to get a Belkin Pro Series. Hopefully it will work for my needs :)

I read somewhere that the Earth is flat ....

That ALL politicians are honest and only have the constituants best interests at heart...

The size doesn't matter ...

< the list could continue, but won't >

Chances are it was not a "network" person that made that comment.

FWIW

signals travel in copper wire at the speed of light. the signals will have to travel an extra 19 feet. Hmmm lets see an extra 19 feet at 186,000 miles/sec. Well you do the math, but it will take longer

Inncorrect.

Electricity travels in copper wire at about 1 quarter of a millimeter a second.


Imagine you had a 1 mile long pole on the ground, if you were able to push it 1 cm in 1 second then at the other end 1 mile away it would also move 1 cm.

At 25' there's nothing to worry about. Just get the cheapest cat5 cable you can find and it will work fine. No need for expensive "special" LAN cabling. Just a waste of money.

That's why he said "signals" and not "the electricity". :) I'm sure he's aware of drift velocity, even if he doesn't know it by that exact name.

general progation delay for twisted pair is somewhere around .78 I believe. Much higher for fiber.

UTP is ~66%. Coax varies by type and grade from 66% upwards to 84%.

Fiber is also in the mid-sixties, generally speaking ... varies somewhat between multi-mode and single due to the propagation method.

Gotta run

heh, if anybody know it would be you Scott. Thanks for the clarification.
