Please log in for more thread options I am kind of new to this, so bear with me. Anyway, the problem that I am having: I have a Linksys Wireless G Router that I have hooked on the bottom floor of my friend's 3 story house. Reception on the top floor is poor at best so I decided to hardwire a Linsys Access Point upstairs. I ran a length of Cat 5e through the basement crawl space and up the walls outside, then back through and installed an RJ-45 jack on both ends. Used the patch cables that were included with the router and access point to connect, and the connection light did not come on. On the Access Point it blinked intermittently. I think the problem is coming from the fact that at the termination points, where I connected the jacks, I untwisted the pairs too much. I am going over tomorrow to try out this fix, but I wanted to see if there is anything else that I should be aware of or look for as a fix if I can't get this to work. I don't necessarily need to maintain pure 100mbs Cat5 standards; I just need the access point to function properly. Thanks. Ryan | ||||||||||||||||||||||||||||||||||||||||||||||

Please log in for more thread options Most often the problems with this type of installation have to do with the matching of the cable pairs rather than the amount of untwist. I would check to be certain both ends were wired using the same pattern, either the T568A or T568B pattern. Split pairs will give you some of the symptoms you describe. It is also possible that you need a cross-over cable between the router and the access point. | ||||||||||||||||||||||||||||||||||||||||||||||

A properly wired cable will work fine at 100 Mb. If it doesn't you've got a wiring problem or cable fault. | ||||||||||||||||||||||||||||||||||||||||||||||

If on one end of the link you have a link light (and no activity) it usually means that the receiver senses presence of the signal voltage, but the transmitter does not get connected to the receiver on the other end. The receiver is on pins 3 and 6, so you should fist look at pins 1 and 2 at the end that has light and pins 3 and 6 at the end that does not have light. The untwist normally does not have such dramatic effect, and is only affecting your bit error rates, but not the actual connection. -- Dmitri Abaimov, RCDD http://www.cabling-design.com Cabling Forum, color codes, pinouts and other useful resources for premises cabling users and pros http://www.cabling-design.com/homecabling Residential Cabling Guide ------------------------------------- ##-----------------------------------------------## Article posted with Cabling-Design.com Newsgroup Archive http://www.cabling-design.com/forums no-spam read and post WWW interface to your favorite newsgroup - comp.dcom.cabling - 747 messages and counting! ##-----------------------------------------------## | ||||||||||||||||||||||||||||||||||||||||||||||

It turns out that I had wired it wrong... the pairs were done incorrectly. I'm pretty surprised that none of the jacks that were for sale at Fry's Electronics are color-coded for 8 pair nowadays. It's still the old fashioned red, green, yellow, black, etc. I'll do a search for the wiring schemes that were mentioned earlier. Thanks for all the help.
