How di I terminate the QVS Cat6 RJ 45 plugs? - QVS 100pcs CAT6 RJ45 50u Crimp Connectors with Wire-Loading Guide (CR6SD-100)

are you wiring for 486a or b config. send me a picture of the back of the rj 45 plug

Just buy premade cables at monoprice.com, they cost a few dollars a piece.

Before you change anything - is this a new device you are hooking up or had this thing worked in the past? First thing to do is reboot everything starting with the modem and ending with the computer at the end of the line. Wait at least 30 seconds between each device. Review all the connections - everything plugged in where it should be? (this is of course your question - see more below).

Eithernet connections (plugs) are RJ-45. The RJ-45 looks like a RJ-11 (telephone jack) only bigger. Typically, the RJ-45 will not fit into the RJ-11 AND SHOULD NOT. Why? Your Cat 5 eithernet runs on very low voltage and signal (packet switching). If you succedssfully get the RJ-45 CAT 5 cable into the RJ-11 phone jack, when the phone rings, you will be sending 60 volts into your network. Can you spell "Do I smell smoke?" A RJ-11 will have up to 6 wires (one pair or two pair or three pair) in the jack and up to 6 'buds' on the RJ-11 plug. A RJ-45 will have 8 wires (in the jack) and 8 'buds' on the plug of your cat 5.

Your device may say DSL on the Cat 5 connection - count the wires inside or the jack.

There are other Cat 5 connection types, punch down and terminal screw types, I dont think you are talking about either.

On your AT&T modem, you should find a RJ-11 which will attach to a near by telephone jack and a RJ-45 for your Cat 5 cable. Your modem may also serve as a router and as such would have additional RJ-45 ports. I suspect you are using a separate router for your home network. As such, one of the ports on the router should be marked Internet or Upload or maybe it is a special color or is set aside from the other ports. That special port will be connected to your modem and your other computers will use the other, lesser ports.

Of course, you could call your service provider for clarification also.

You should use a RJ 45 Crimper for this

Some RJ 45 jack cable has fault so try with another RJ 45 jack cable .. Purchase new rj 45 jack cable from nearest computer shop. There must be 2 port on modem 1 for ADSL phone line cable and otthr for LAN ethernet port means RJ 45 jack port. Try with another rj 45 jack cable it should be connect.Make sure that LAN port of modem is not faulty means make sure pins on that port are not break. Let me know if you need further assistance. Thanks for using FixYa.

From what I remember you would need a 'rollover cable' that connects the pins to each other in reverse order (e.g. 1 to 8, 2 to 7, 3 to 6, 4 to 5, 5 to 4, 6 to 3, 7 to 2, 8 to 1)

You are probably looking at a RJ-11, used for telephone (dial up - modem). You are trying to put a RJ-45 connector in it.

The RJ-45 should have 8 wires while the RJ-11 may have as many as 6 connectors.

Thank you for your voluntary work with this organization.

Note: If you were to plug a RJ-11 into a RJ-45 port and if it happened that you plugged the other end of the phone cord (RJ-11) into a phone jack --- and the phone were to ring ... you would be pumping 60 volts into your computer. Be very careful with these connections. You would then need butter and jelly for your toast, which is what your computer would be.

Ok - recap: Both look very similar ...

Ethernet = 8 conductors - RJ-45

Telephone = up to 6 wires (may be 2 or 4 also) - RJ-11. NOT interchangable.

So how will you connect? If the laptop is not builltin wireless, you can get a PCMIA card for the slot on the side that will allow wireless or ethernet. Get the card at your computer store. ... Or ... use the built in modem for dialup., You would of course need a dialup account somewhere.

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 FixYa.com

RJ -45 is a type of connector used on cat5, cat5e....etc cables to connect networked devices...the RJ stands for registered jack but there is really not much you really need to know about it....a RJ 45 JACK is a little bigger than a telephone jack, you'll notice the female type of input on your computer or laptop and the male end will be on the end of the cable that goes into this jack....hope this helps

RJ-45 Pins are with the spring tab down and read left to right. Do you have an RJ-45 Crimping tool?
Just use 568-B or 568-A on both ends of the same cable.
