What are you doing? Are we talking about telephones (RJ-11) or are we talking about routers and ethernet cable (RJ-45)?????

RJ-11 will fit into a RJ-45 but a RJ-45 will not fit into a RJ-11. Translation, your telephone wire will plug into your router/computer port but your Ethernet wire will not fit into your telephone jack.

If you are working on a telephone, as long as you have dial tone on the other end, it doesn't make a big difference. You should have a polarity checker to insure proper polarity but even if it is wrong, most phones will work most of the time. Get a polarity checker at Radio Shack for about $10.00

If you are working on a router ... well, it is no wonder your network will not work. You cannot split one RJ-45 port into two "Ports" using a telephone RJ-11 splitter. Never, Never, Never, plug your router cable into a telephone jack (RJ-11). Yea, Yea, Yea, I know, I just said a RJ-45 will not fit into a RJ-11 but if you have a telephone cord pluged into the router, guess what, 60 Volts will smoke it. When the phone rings, it rings with 60+ volts and will smoke any computer device it can smoke looking for ground.

If you need more computer ports, get a bigger router or bigger switch or bigger hub or get a wireless router to accomodate your wireless devices.

I hope I have answered your question.

Thanks for your interest in

When both single lines are plugged into the splitter and then into port 1/2 the lines do not work. If I unplug one of the lines from the splitter line 1 will work.

Hi Amy,

I have two of these phones. The feature set is really good. The only thing missing is a "Voice Mail" indicator light. You have to pick up the line and listen for the intermittent dial tone.

The other problem is that they are not very reliable. Both of my originals developed problems with the answering machine portion, but were replaced under warranty. Have had issues with one of the replacements also and now use it with an external two-line answering machine.

Regarding your problem, there are a few possibilities. Not all phone cords are created equal. The cord that goes from the wall to the phone uses a plug/jack called RJ-11. An RJ-11 connector has room for four contacts. The contacts themselves are just gold-plated wires.

Take a very close look at all of the cords you are using, as there are two different types that look nearly identical. A single line cord will only have two wires inside, and the RJ-11 connector will only have the two center pins filled with the gold contacts. A two-line cord has four wires and the RJ-11 connectors will have four gold contacts at each end.

Once you are sure that your cords are all two-line (four gold contacts on the RJ-11 connectors), the next thing is to understand how two different lines are put into one cord.

The first (main) line will occupy the two center contacts. To add a second line, they need to connect to the two outer contacts. It may be that you need to re-wire the wall jack on one of the lines.

If they are both wired to the two center contacts, the splitter cannot do its job. The way to tell this is to make sure that each wall receptacle will give a dial tone when plugged into a single line telephone. If that is the case you will need to re-wire one of the wall outlets.

You would need to remove the wires from the center two slots on one line and insert them into the outer two slots. Take a look at what you have with regards to cords and the results of your tests with a single line phone. If you need to rewire a wall outlet, I can walk you through that.

Can you set up a zte720 wireless home phone to a Motorola NVG589 U Verse wireless router for Boardband service?

There is no port for broadband(RJ45) output in ZTE720 so if your phone line terminates at ZTE720 then Motorola cannot be connected to it.
On the other hand if you terminate the your phone connection at Motorola NVG589 then you will get broadband and no output to connect to a phone line.
However there is a way and that is the phone line coming to your home can be connected to a splitter (it has one input and 2 outputs, one for phone(ZTE720) and other for router(MotorolaNVG589)).
Splitter will provide output for both devices and they can work simultaneously.

Your connection.

I got my new XFX NVIDIA GeForce 8600 GTS 512MB yesterday for my dell dimesion 9200 but when i was connecting it to the power supply the instructions say u have to "connect two molex connectors from the...

You can but a molex splitter so that you can plug the single molex you have into it and then have two, like a "Y". You will probably have to go online to a company like,, or who sell power supplys. I realize that means waiting a few days but the alternative is to either modify your PSU which voids the warranty or buy a different one. The splitter is inexpensive.

All of a sudden it will not send a fax. I called the fax number and get the chirp, but my C6180 is not sending. I get the message to check my connections.

That has happened to me on several HP's I have owned try replacing the cord connecting to the phone line if that does not help look where the socket is for the phone jack and with a flashlight check to see if the 4 wires are sticking up they are very small and bend easily see if they are touching if they are then use a safety pin to straighten out the wire. Also if you have a splitter thay connects it to the phone line try removing the splitter and see if it works. If you still have a problem go to select your printer and use auto detect and let it trouble shoot the problem for you. There is also free online help with the problem as well. And if you register it it will be under warrenty and will save you from having to pay for the repair.

My phone line comes through a cable modem. how do i connect

well no promises but this may work

items you will need

2 coaxial cables

3 way coaxial splitter

1 old phone cable you can sacrifice

soldering iron (optional)

solder (optional)


take a coaxial cable and cut on of the ends off, throw the severed end away and strip the insulation of the coaxial cable (only strip about 3 inches of it away.

seperate the coper (or sliver wire) from the wire center wire and twist toeghter to make a neat wire

strip some of the insulation away from the white center post revealing the coper wire inside

cut end off phone cable and take about 4 inched of insulation away

connect the green wire of the phone cable to the copper outter most wire of the coaxial cable and tape it so that there isnt any of the outer most wire showing

connect the white wire to the center wire of the coaxial cable and tape so that there isnt any wire showing

connect the coaxial/phone cable you just made to the 3 way splitter

connect the coaxial line that comes from your house to the splitter

connect the other coaxail cable to the last available port on the splitter

connect the non-modified coxial line to your modem/router

connect the phone cable to the fax

this might work, no promises, i havent tried it, but it might work and is worth a try

Piggy back power splitter

You can connect the splitter to any of the 4 connectors that power IDEs(Hard Disk, DVD ROM, CDROM etc.,). The splitter's sole purpose is to split one 12v supply into two 12V power supplies so that we can connect two devices instead of one. You can disconnect the power from DVD connect the splitter to it and then use one of the two 12v supplies from the splitter to connect to the DVD drive and the other to the HDD fan.

Phone jack

If you can see the pins in the jack, are they corroded? Also, is the phone cord new? You'll want to try a different phone jack if you have one available.
