How to test existing ethernet cable outlets?


Your testing method seems reasonable and probably rules out continuity between those two drops. (The exception might be if your router or switch don't have Auto MDI-X sensing and you needed a crossover cable, but that's unlikely as most devices made in the past few years should figure that out automatically.)

So if these two drops aren't directly linked, where do they go? Most often these run to a basement, attic, or closet. Possibly (but not necessarily) wherever your home's telephone wiring terminates. As a first step, try to figure out where the lines go - perhaps you can find a common termination point and locate your router or switch there to supply the drops.

If visual inspection isn't working, you can use a tool called a wire tracer or tone-and-probe kit to track where the cables go in your walls. The tool has two pieces: a tone generator and a probe. You'll either plug the tone generator into an RJ45 port, or open up the drop and clip the tone generator to a...

Has the Internet stopped working? Has you done all the testings? Have you called the Internet guys already? You probably heard them say that there’s no fault in wired network. Oh, that can be frustrating! Today, I will show how you can test and repair the Ethernet cable network.

The truth is that the answer is sometimes as simple as the Ethernet cable not working. Yes, a bad Ethernet cable can cause major connectivity issues. Also, it is not unheard of for a faulty cable to wreck Internet performance. This means that even though you paid for the 100 GBPS package, you will not enjoy the speed or connectivity.

How to Test Ethernet Cable Without Tester

Now, let’s learn how to test Ethernet cables so that we don’t waste our time trying to figure out why exactly there are so many connectivity issues:

1) If your Internet is Slow or if there are Numerous Drop-Offs

Most Ethernet cable testers just check for continuity and proper pinout.

There should be no signal on the line, both ends of the cable should be plugged into the tester.

On a straight cable the lights should be 1-1, 2-2, 3-3, 4-4, etc.

Ethernet network cables use 4 twisted pairs of copper wire that have a specific twist per foot that varies depending on the specific pair. This is used to prevent crosstalk between the pairs. When installing plugs or punching down connections you need to maintain the twist ratio all the way to within 1/4 inch of the termination.

Installing RJ45 network plugs requires a special crimping tool and a little skill to get the twisted pairs in the right order. The RJ45 plugs are specifically sized for the wire in CAT5 or CAT6 network cable.

You can either use the 568A or 568B standard, with the latter being the most common. Just be sure to pick one and wire everything to that standard. The pinout can be found here:...

There are three primary types of network cable issues: connectivity issues, performance issues and continuity issues. If your network connection has stopped working and you believe it may be caused by a faulty cable that connects you to an Ethernet network, there are three basic tests you can perform to see if the cable is the problem.

Connectivity issues are usually caused by a fault in a cable or its connections at either end. A quick test to check the connectivity is to plug the suspected cable into the network connector of another computer or network device. Typically, the jack you plug the cable into is part of a network adapter, which provides the interface between a computer or device and the network cable.

Network adapters typically have one or two LED lights that display that an established connection exists and transmission activity is occurring on the line. A network connection is indicated by the network...

Whether installing new cable or troubleshooting existing cable, cable testing plays an important role in the process. But do you know the process of using cable tester to test Ethernet cable? First we should know the product of Ethernet cable and network cable tester clearly.

About Ethernet Cable
An Ethernet cable is one of the most popular forms of network cable used on wired networks. An Ethernet cable has eight wires that are arranged in four pairs. For current to flow correctly, the wire pairs must be connected in the proper order. Ethernet cables normally support one or more industry standards including Category 5 (CAT5) and Category 6 (CAT6).

Ethernet cables are physically manufactured in two basic forms called solid and stranded. Solid Ethernet cables tend to offer better performance and protection against electrical interference, while stranded cables are less prone to physical cracks and breaks making them more suitable for travelers and portable...

I finally got it all sorted out!

The switch is a managed switch, but the issue with it was that it wasn't marked with any sort of IP. I had been using Angry IP scanner to identify the IP's that were in use, but it wasn't giving me results on any of the switches or routers. As per the suggestion of rjones1, I was able to use Advanced IP Scanner V2 to correctly identify which devices were switches and the IP/MAC of each. Through trial and error I found the IP of the switch in question.

From that point, it was just a matter of identifying ports and their respective outlets. I didn't have the proper toner here onsite, and I didn't wanna wait for one to get shipped, so I got a little crafty. I used a router with an active connection indicator LED, and plugged it into each of the outlets. I was able to use that to identify which ports were active/inactive. For each outlet, I had to do some unplugging/plugging with the switches until I got the connectivity indicator...

Most wired devices these days use auto-mdix to automatically configure themselves according to how the other device/outlet is wired. So it just doesn't matter. You can't do any harm. Either it will work or it won't. And if it doesn't work, it's most likely because things aren't hooked up, at all.

IOW, if you have a modem and router installed in the home office, both working properly and connected to your ISP, connect a LAN port on the router into the wall outlet, plug a PC in the den’s outlet, and can’t establish connectivity, it's probably because the runs from each room (or at least in those rooms) haven’t been terminated into a switch/hub at the MSDE.

A few years ago I had a new home w/ structured wiring too. All the rooms were wired, but the MSDE had no switch/hub. I was expected to add my own (or perhaps a router if I wanted to make my ISP connection at the MSDE). It just doesn’t matter where you install the router, whatever is convenient. You just have to use...

Ethernet cable, also known as Category 5 cable, is used in cabling for computer networks. It can also carry telephone, video signal and connects computers to routers and cable modems. Ethernet cables need specific wall outlets, female receptacles which accept male cables from the specified device. You'll need some specific tools to hook the Ethernet cable to the wall outlet.

Place your Ethernet cable stripper over the end of your cable. Ideally you want to place it 1 1/2 to 2 inches in from the end. Close the stripper and twist it around the cable two to three times. Pull the outer jacket off.

Separate the wire pairs inside. Each pair will have a coloured wire with a white stripe and a white wire with a coloured stripe. The coloured stripe on the white wire will match the coloured wire.

Look at the back of your keystone jack. The connector will be labelled to where the wires should go (i.e. blue, white-blue, green, white-green, etc). Push the specified colour...

Adding a wireless router to an existing local area network adds a Wi-Fi access point to the network so you can share a single Internet connection. The wireless router and other network devices, such as switches and hubs, handle most of the configuration process automatically. However, the process varies if you're connecting the router to a network with an existing shared Internet connection or running the Internet connection through the new wireless router. The ports you use to connect the router to the rest of the network change depending on how the network connects to the Internet.

Extending the Network With Wi-Fi

Step 1

Plug the wireless router's A/C adapter into a power outlet and connect the ends of an Ethernet cable to the computer's LAN port and one of the router's LAN ports.

Step 2

Follow the wireless router's model-specific setup instructions included with the device to enable Wi-Fi. The computer used to set up the router can be...

The inception of Wireless routers has brought an age where the traditional Ethernet cables have lived out their usefulness. Many home and office networks connect computers to Wi-Fi technology thus, eliminating the need to lay out wires. In reality, though, Ethernet cables are still the most stable and secure mediums to use when connecting to a network. This is probably why some people and companies still prefer it. For those that do, the problem of laying out the wires throughout an office or a home becomes a Herculean task, especially if the computers are located in different rooms. Fortunately, there is a way to side step this through the use of power outlets.

Believe it or not, you can actually send and receive digital data using the electrical wiring in your office or home. And, you can do it without having to replace any wires or do any wiring at all.

Picture the situation. Before proceeding on how this fantastic option is done, you will need to picture a...

A typical network consists of nodes (computers), a connecting medium (wired or wireless), and specialized network equipment like routers or hubs. In the case of the Internet, all these pieces working together allow your computer to send information to another computer that could be on the other side of the world!Typical networks today use two differentaddressing mechanisms on top of each other - and addressing is anecessity for data exchange between any two networked machines.The lowest level addressing is the MAC acess (akaethernet addresses, hardware addresses). The MAC addresses are used foraddressing within a single LAN. MAC addresses are programmed intothe hardware (typically network adapters), Every Ethernet card hasan unique MAC address (it is possible to change MAC on most adapters it'spossible, but not advisable except in special circumstances).The next address level are IP (Internet Protocol) addresses.

Consultants and end users can lean on standards when specifying performance requirements.

Many structured cabling installations begin with the preparation of a detailed written specification for each system component. Such specifications may be necessary to ensure the correct product is used for the intended application. Specifications also ensure all products offered are equal in a competitive-bidding situation. Consultants and end users often find that they lack the breadth of knowledge or experience necessary to prepare a complete, detailed specification for optical fiber and fiber-optic cable. This fact is not surprising because it takes a significant effort to keep abreast of changing product offerings as well as the most recent product evaluation and measurement technology. However, consultants and end users can use industry standards to specify the necessary products without having to delve into excruciating...
