Re: [newbie] limit of cat5 cables? (length)
The maximum lenth of a 100baseT (CAT5) Ethernet run is 100 meters, or a little over 300 feet. About the only problem you are likely to run into with the distance you are covering is if you run the cable next to a source of RF interferance such as a flourscent light ballast. -Original Message- From: Paul Rodríguez [EMAIL PROTECTED] To: newbie [EMAIL PROTECTED] Date: 10 Nov 2001 17:37:56 -0500 Subject: [newbie] limit of cat5 cables?

Re: [newbie] limit of cat5 cables? (length)
Actually, there's no tested maximum length for CAT5. However if you're going by the specs, 100M is the max between some sort of device. Whether it's a repeater, a hub or something. Many of use have done networks where we've used CAT5 much longer then 100M for whatever reason, and have had no problem. But, for those of you who have gone through MCSE or Cisco, or any network training, they say the spec is 100M, for performance. The instructor will also tell you after you've learned the spec, and passed the test, forget the spec! In the real world, you do what works. More then 100M of CAT5, works. I think many of us can attest to that. tdh -- T.

Re: [newbie] limit of cat5 cables? (length)
No trouble at all with CAT5 at that distance. If you do not want to drill holes wireless is good. (but cables are cheaper) I use wireless at 11Mbps from Melco/Buffalo I have a PCMCIA adapter with a Melco wireless card in the desktop PC upstairs and a wireless hub colocated with my cable modem. Mandrake 8.1 recognises the Melco PCMCIA wireless card automagically. The only issue I had was configuring the PCI-PCMCIA adapter. This is a common issue with several makes of wireless PCI-PCMCIA adapters, but there is an excellent HOWTO available, and of course advice available from other users. The Lucent Orinoco wireless system is very popular with Linux users, and there are tools developed specially for it. useful links are http://pcmcia-cs.sourceforge.net/ http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/ http://sourceforge.net/projects/korinoco/ There are 11 wireless channels to choose from to avoid interference (Microwave ovens can be an issue on some channels) The data is encrypted and so is safe, only computers in your workgroup can decode it. Of course passing blackhats with a supercomputer in their car could crack the encryption, but is your data really worth stealing? Range can be an issue. The Meco system I use has an integral antenna which is not really up to going through more than 1 or 2 walls. The manufacturers quote range as 300ft, but that is in clear air. Where the target device is more than 2 walls away I have to use an external antenna which adds to the cost. Other manufacturers such as cisco have a better (larger) antenna on the PCMCIA card HTH Derek On Saturday 10 November 2001 22:37, you wrote: Hi, everybody.

Re: [newbie] limit of cat5 cables? (length)
There's a limit of 100 meters (over 300 feet). So, 40 feet is no problem. At 05:37 PM 11/10/2001 -0500, you wrote: Hi, everybody. I have a DSL connection coming in to the upstairs computer.

Cat 5 cable does have a range limit, but it something like 100 meters, so you are well within its capabilities. I am currently looking into wireless for my home, because my wife can't stand the cables I have running between the network hub and three computers, across our living room. The only downside I can see is the initial cost... and even that's not too bad, but my expendable cash at the moment is nil :-( Dave -- Fourth Law of Revision: It is usually impractical to worry beforehand about interferences -- if you have none, someone will make one for you. msg81299/pgp0.pgp Description: PGP signature
