cat5 cable-how long??

hi tehre and thanks for your fast reply as usual,
have adsl modem nb1300 plus 4.
my son pc is in his room and i need to conect it to my router so he can have internet access.
i can reach his room with 10 meter cable.
i have 15 meter cable.
question is?
do you lose speed if cable is longer 5 meters?
my adsl conection is 1500/256.
i canected his pc on router but with only 1 meter cable and i was playing cs( i know-2 old) and could surf the nett very fast.
Any significant slowdown to excpect or no?
thnks

You should be good up to about 99 meters with no repeater.
Well, they say 100 meters... but I've been told before not to exceed 99 meters.

You will be fine with 10 or 15 meters.

Nah not really, sure it will slow down since it needs to travel longer, but it's probably not even measureable in seconds.

Dont think the signal starts to degrade...attenuate til 100 meters or so...

I think you will be fine

Other things can interfere...like floresent lights and large power sources

We musta all posted at the same time :D

Nah, you won't be able to notice the difference due to cable length... unless you exceed the maximum. Which you will not be doing...

The speeds will def. decrease once your son learns about p2p and bittorrent and other naughty sites out there... I have to constantly kick my roomates PC off when I'm fragging... His darn streaming pr0n!

BTW: How old IS your son? I'm no parent... but most people I know with kids won't let them have PCs in their room. Just so you can see what they are doing. If it is in their room... then they can close and lock the door and do stuff you might not want them to be doing... At least... I know I did.

As mentioned you should be fine with that sort of length and watch for running the cable near to power cables. If you can't avoid them get shielded cable.

Also try to avoid sharp 90 degree angles in the cable.

Does that really make a difference?
I once tied a 10 ft. cat 5 cable in lots of knots and it still worked fine as far as I could tell...

Excellent point Phish ;)

As for the 90 degree angles....really depends on the cable....have seen cabling with no flexablity...older...cheaper...cant remember what its called....... :rolleyes:

although I have seen breaks in the wiring at the RJ45 connector...when the cable is pulled too tight...no matter what type it is

oh yeah...and dont step on those connectors either...breaks them real good!! ;)

I've never had an issue with bending the cable. I only have issues when some moron [me] left a 500 ft coil in the ceiling with one end patched and the other end un patched. Two days later just grabed the other end of the cable and patched it into the other stack. Took me almost three days to figure out why the new line i just pulled didn't work.

As with most cables turning a sharp 90 degrees has a tendency to break the conductors, especially in solid core CAT5 cable. Nothing like pulling a 200 foot cable through the ceiling just to find out it doesn't work because you kinked it somewhere and broke one of the wires.

As far as the length goes, there is no difference in a 15m and 10m cable as far as speed goes. The difference that the length could possibly make will be so small that the delays in between transmissions is much much longer and thus takes the length completely out of the equation.

Also, as Aspman stated, watch out for power cables, floruscent lighting, and really any electrical component. Try not to run it within 5 feet of anything motorized like a fan (ignoring case fans obviously), as the windings in the motors cause a lot of RFI.

In most situations you won't run across any problems on a small network. These RFI issues and everything mostly stem up in large networks were interference can spread to a lot of devices.

I agree .... :)

thankyou guys for answers,
my son is 9 and the other 7 and they both have pc in their room but so far no access to nett so didnt have any problem to worry so far.
now is time to fine tune their pc(;)).
Of course on their pc they are limited users with noway to find my password and if i start seeing my screwdrivers missing or they lock in the room they will be in all sorts of troubles.
thanks for pointing to that problems but i was lucky when i had computer my mum didnt know what that box means(soo i can do whatever i wanted)
i know little bit more and dangers of nett and they will be guarded well
thanks for your answers off tomorrow to buy cable and seen nice fancy laser mouse uhhhh tempted.

Its not really a "laser". its just an LED. When people say "Don't look at the laser! It'll burn your eye!" I normally pick it up and put it to my eye and start screaming! It doesn't hurt your eyes at all, as far as I can tell.

The optical mice really are nice. They should be pretty inexpensive by now. They are so much more smooth and the last a LOT longer. They don't get dust or hair on the "trackball" (because it doesn't exist). However, you are limited as to which surfaces you can use it on and you shouldn't use it on a glossy mouse pad. It won't work on glass and doesn't work well on shiny surfaces because. I've found it best to use just a plain dull fabric topped mouse pad.

Something strange though... every so often, I'll see my mouse cursor just move across the screen when I've stopped using it and started reading a webpage or etc. This happens on multiple PCs while using the optical mouse. (work, home, laptop) Not exactly sure why it does it... Or, if I have the bass up too loud, it'll move itself slightly because the mouse is vibrating.

Just because I know you are dying to find out, here is a quick summary of how they work.

Phish,

You might want to be careful there. There are LED mice and laser mice. The ones with the bright red light that you can see glowing immediately are the LED ones which won't really do much to your eyes (although I probably still wouldn't hold them up to my eyes). There are some that logitech make, and I'm sure other manufacturers, that do in fact have lasers in them. These mice can and will hurt your eyes if you start at them for any amount of time.

In general, Optical = LED, and Laser = Well, laser.

Oh... I'll have to watch out for those! Thanks for the heads up!

Fortunately... Dell is too cheap to ship laser mice and only ship optical mice?

Now I really feel like a dumbass... lol

Boy this Thread was an overkill. Dont you think?
