How do you extend a short network cable?
« on: March 06, 2010, 05:46:13 PM »
Guys,

In the office, some networking guy installed our network. However, for more than two (2) years, we have not been able to use two outlets since the cables are short.  We cant change the cable itslef since its imbedded in our walls.

How do we extend it so we can use these last two local area network connection?

Thanks in advance

Use an F-F RJ45 coupler...

Go to a PC store and ask for a 'coupler'  it's a small box with RJ-45 sockets on both ends.

Where can one get a good quality (Cat6) coupler?  It seems not many stores even carry RJ45 couplers. I once tried to buy 2 pcs from PCX but they only have 1 onstock, and more likely than not it's not a high quality one (how do you check the coupler quality).

^^Hmmm...   So far, I have only used brandless, "china generic" ones you could get at computer stores or other... They've worked good so far, even for somewhat longer spans (~20m), but they do not identify themselves as CAT3, 5/e, or 6 compatible.  I'd much prefer branded ones myself (maybe Intex, Omni, Seimon or the like) but can't find any when I need them (!)...

The thing I look at are the conductors.  They have to be very springy and copper-shiny (untarnished), as well as fit snugly with an RJ45 (bring a sample cable).  If I anticipate moisture buildup, then I just use self-fusing butyl tape to wrap/seal the coupling from the outside.

Thanks for the tips, josekym.  Any idea where I can find "very springy and coppery-shiny (untarnished)" conductors and how much they cost?

^^Try Ace Hardware or Handyman DIY... I got some from Ace some time ago...  Forgot the "brand" markings on the packaging, but they were 60 pesos each.  In our area, they can also be had at certain electronics, electrical, or hobbyist shops...

I recomend to use a RJ45 I/O its like a telephone outlet. If you like I can refer you into our supplier.

Modular Jacks would be too cumbersome for the TS's needs... not to mention more costly (for the same signal quality)

My network setup is basically like this:
ISP modem ---> [router1: SSID1] ---> [wireless ethernet bridge connected to SSID1] ---> [router2 configured as AP: SSID2]
router1 is on the 2nd floor. wireless ethernet bridge and router2 are both downstairs.

I use the wireless ethernet bridge primarily to connect my desktop PC and our Android TV box to router1. Recently, I decided to connect router2 as AP to the ethernet bridge to get a stronger signal for our phones downstairs.

The setup apparently works with our phones switching to router2 when downstairs and switching to router1 when upstairs. Now my problem is sometimes we experience random loss of internet access from router2.

What could be the problem? The only thing I could think of is that there may be an "overlapping" of wifi signals from router1 and router2. If so, how can I know how much to reduce the radio strength of each router to avoid the overlap?
Is there any other cause of failure?
