Access point wiring problems?

Hi all,

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

Check your RJ-45 jacks and make darn sure you have a good connection on all
the wires. Also make sure you have the right wire connected to the correct
pin at each end too.

Thanks for the reply. Yes, I have gone over the connections as far as the
pins go many times, and I am pretty sure that that part is right. I'll
check again tomorrow. I have also used a signal thrower to test the pairs
and that works. So, I am back to the untwisting of the pairs. Do you know
if this causes complete lack of connectivity ever?

I know you've checked the wires already, but perhaps you don't need the
cable wired in a "patch" configuration, but in "standard". EG the
send/receive pairs are NOT crossed. (Or the other way around. You have
them in standard but you need patch.) The docs for your equipment
should tell you.

Another problem may arise with the wireless access points using the same
frequency/channel.

Thanks to everyone for their replies. I rewired, untwisting and stripping
less, but I think the problem was that I had wired the loops incorrectly.
I'm surprised that none of the jack available at Fry's have the newer,
8pair color codes. They are still red, green, blk, yellow, etc.

Anyway, thanks for your replies. Very helpful for what to look for in the
future too.

that doesnt suprise me...regular telephony wiring color coding.

Late reply here, but yes, yes, and YES, untwisting pairs near the connection
can and eventually will cause a problem called NEXT or "Near End
Cross-Talk". We spent over a year diagnosing a major intermittent network
problem to find that the 'cable guy' left too much untwisted, uninsulated
wire near the crimped jacks in the wall plates. A relatively cheap cable
tester will tell you if your pins and what not are right- but only a high
end cable tester (one no real human being can afford) will only tell you
about things like 'Next'.

When you say the signal is weak on the 3rd floor, define 'weak'. I have a 3
story house an although the signal is fairly 'weak', my connection is
stable. Yes, it drops to about 2megabit, but with a range of 300 feet in
OPTIMAL conditions, that's expected behaviour. And since most of my network
activity is occuring over the wan when I'm on the Laptop, anything over
about 1mb is a wash. I would strongly advise getting a little utility
called "NetStumbler" and analyze your signal strength, and possibly reorient
the router on the bottom floor.

Good luck
Paul
