Do you have a ethernet checking device? (Lowes and Home Depot both have several devices - price in the $50 to $75 range.

You could replace the two ether net cables and see what happens.

What jack does the Slingbox Ethernet cable hook into on a ATT 2wire modem? I have a choice of DSL or one like the phones are hooked into. It's not working now so I'm backing up each step, no matter...


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.

Thank you for your question @ FixYa.com - I am sorry you are having this trouble and I hope I have helped you in some way. I hope you are able to get your system back up in short order.

I have the GXV-3000 IP Video phone, there is a RJ11 jack on the back. How do I use the interface? Connect to my phone line from ATT or connect to a regular phone (as an extention?)? Thanks.


A copy of the user manual for your IP phone is found here: http://www.grandstream.com/user_manuals/GXV3000_User_Manual.pdf

I have browsed through and found no mention of an RJ-11 port on the back, only two RJ-45 Network ports, one for connecting to a PC in switch mode and one for ethernet mode.

If your phone is different and DOES have an RJ-11 port (as some IP phones do), I can only assume it is to connect to a landline to offer landline services as well as IP services.

Under those circumstances of course DO NOT attempt to plug in your landline RJ-11 into an RJ-45, it will not work and you risk shorting something out.

I want to connect a CAT5e Ethernet cable (with or without a RJ45 connector) from a DSL router to an older computer that only has a RJ11 input. This will be used for DSL internet service only -- no...


The only "outputs" from a DSL-router are:
* RJ-11 telephone-jack, only if the router also supports voice-over-IP,
* RJ-45 Ethernet port (always present)

You need to purchase an internal network-card, to create an RJ-45 port on the computer, and then use the CAT-5e cable to make the connection.

I have a cable modem that doesn't want to accept the RJ-45 cable (I think that's what it is called.) I've tried several different quality cables with no luck. Strange problem. Any tips?


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.

What wiring to use to connect our RJ45 connectors for computer


The order you give is right. Ethernet uses the orange pair and the green pair (1, 2, 3, 6). Phone uses the blue pair (4, 5).

Plz explain me exactly for which purpose RJ-45 cable used ?


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

Wiring on a RCA RJ-45 wall jack


the RJ45 wallplate is not meant for ethernet. It's an 8P8C connector for a phone. Will it work as a network jack? Maybe. I wouldn't use it, but if you really want to try, wire it thusly:

1 Blue --- Orange/White
2 Orange --- Orange
3 Black --- Green/White
4 Red --- Blue
5 Green --- Blue/White
6 Yellow --- Green
7 Brown --- Brown/White
8 White --- Brown

I'd still recommend a CAT5 wallplate with a CAT5 jack.

Dont know how to hook up cat5e cable to a leviton cat5e jack


Those two jacks are telephone jacks (RJ-11) not ethernet (RJ-45). The jack marked telephone is for a phone, and the jack with a rectangle symbol is for the telephone line into the wall.

You need to buy an ethernet PCI card - without one you can not use a cat5e line (which has an RJ45 connection).

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.
