Expert first aid What should I do if the 100M network cable is not working

Straight line, i.e. positive line, standard (568b): the line sequence at both ends is the same, from left to right: white orange, orange, white green, blue, white blue, green, white brown, brown.

Intersection line, i.e. reverse line, (568a): one end is the sequence of the positive line, and the other end is from left to right: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.

The following is the right choice for positive and negative lines in the connection case of various devices.

pc-pc: reverse line.

PC-HB: positive line.

HB-HB ordinary port: reverse line.

HB-HB Connection - Grade Connection: Reverse Line.

HB-HB ordinary port-level connecting port: positive line.

mode--pc: positive line.

mode--hb: positive line.

If it's a positive line, then the opposite line is according to your connection.

Green, green, white, orange, orange, white, blue, blue, white, brown, brown, white.

Reverse wire-to-head connection.

Orange, blue, white, green, orange, white, blue, green, white, brown, brown, white.

See if you get the wrong answer.

100 meters is too far away, and there must be repeaters or other network equipment in between.

The arrangement of the line is no problem, and the line tester has four lights? Or 1236 lights out of eight?

Generally, it is not recommended to connect the network cable to the switch for testing.

Another point is that the computer is connected to the switch and should not be plugged into the up-link.

Here's how to do it!

Orange White Orange Green White Blue Blue Blue White Green Brown White Brown. That's right. 100 meters is a bit too long, you can join the hub in the middle

The correct ones are white-orange, orange, white-green, blue, white-blue, green, white-brown, brown.

It's useless if the cable is more than 100 meters, and you have to keep in mind that if you really want that length, you can add a switch in the middle.

Line sequence: white, orange, white-green, blue, white-blue, green, white-brown, brown.

The network cable order is orange white orange green white blue blue white green brown white brown.

The transmission distance of the Category 5 line is about 50 meters.

Otherwise, the packet will be lost.

Make the crystal head from it.

See if the crystal heads are in order`

Whether the switch configuration is correct or not is OK.

It is possible that the quality of your network cable is not good, try a different network cable.

I haven't been connected to the Internet for a few days, but ** it is. Unplugging the cat's power supply didn't solve it, but the router was full of signals, indicating that it was a problem with the cat and the network cable. Yesterday I used a screwdriver 1 to pick up the cat's network cable, and the data flickered.

If the quality of the network cable is good, there is generally no problem within 100 meters, this is the theoretical value, if it is exceeded, add a switch after 90 meters, so as to ensure the speed of the network. In fact, it's not that serious, it's only 100 meters, and the real impact on the network speed is not in the network cable, but in the service of Unicom!

Good luck!

Suggestion: Give up!

Reason: Theoretically, the signal quality of the switch is guaranteed, but in practice, the installation, later use and maintenance are troublesome.

The line of good quality is also connected directly, but this line, only dare to say that it is okay, and the signal quality in practice does not dare to compliment, (I have used about 120m on the bureau to say this, and it is by no means a case to draw this conclusion, and I was surprised to find that this thing is related to the weather.) And you were supposed to be fast.

Why doesn't Unicom install, that's why they don't think they can do it, afraid of trouble in the later stage, and then the long line installation can not be done once, where can it be troublesome, but after installation, it will be very troublesome to repair the two heads in three days.

If you want to be faster, you can apply for a 4m. That's about ten dollars more than 2m per month.

In your case, they are too far away to help you pull, and it is estimated that the middle line is not easy to walk.

The Unicom company pulls the general leather wrapped wire, generally two cores, not necessarily twisted pairs, this kind of wire pulling 100 meters is likely to not reach the speed of 4m.

If you want to install it, you can only pull it yourself, buy a little more than one meter, generally a piece of more than one meter, this kind of line is not a big problem within 150 meters, at least it can reach a speed of 10m. After pulling it up, ask them to help you pick it up at both ends, hand you a cigarette or a glass of water, have a better attitude, and in case of a failure due to the long distance, they will also remember to help you repair it.

The maximum transmission distance of the network cable is 100 meters, the quality of the ordinary network cable is poor, the signal is very weak at about 70 meters, basically the web page can not be opened, you can add a signal amplifier, about 200 pieces, but the network effect is not very good.

1. Theoretically, the signal will be attenuated after using the "Category 5 cable" after exceeding 100m network cable, but because the outlet only has a bandwidth of 10m, the use of 105m Category 5e cable can fully meet your needs;

2. The quality of the network cable must be guaranteed, and the T568B standard must be used at both ends of the network cable;

3. I think another thing that needs more concern is how to effectively protect the outdoor 100m long network cable, hehe, how to protect it should be done according to the actual situation.

Network extension device, but definitely put a device at the remote end.

Or with a Cat5e line, it can go up to 150 meters.

Or use ** line extension, but it also needs to install a device at the far end.

It's not that it can't be installed, it's that the staff of Netcom don't want to install it for you, and the line is too long to maintain. After saying that he is 10 trillion total box to your home is not necessarily that high, now Netcom is generally 2 trillion or 4 trillion into the household. If you still want to be safe, it is recommended to use a network cable.

Then don't use Netcom, the service attitude is too poor, generally don't you ask users to open broadband, is there a reason to let users find their own way to wiring?

If it is 10m, the network cable of 130m*** point is good, and the signal quality is acceptable.

Everything else is, in a word, buy a better network cable, it's better to buy a full copper wire diameter, adjust the network card rate to 10, full duplex or half duplex, so if you have a problem, you look for me.

You don't think about this question Unicom won't give you a fiber optic So you just have to be honest and practical, just use the ** line My answer is definitely the most practical.

The impact is not very big, don't worry, you can't feel the difference at all if you use the computer at home.

Just use a normal network cable.

Pick up a small hub hub or switch around 50 meters.

I recommend using a CAT5 cable, if you can, a switch or repeater is a better choice!

There are more than 100 meters of articles in the space, you can take a look!

The specification of the Category 5 twisted pair is 98 meters, and the extent to which it can affect has not been tested.

The distance you measured is not accurate, if it is really 90-105 meters, Unicom can install it for you.

Calculated distances cannot be counted as straight-line distances.

If you think it's so troublesome, don't use his network to surf the Internet... I haven't seen it and I have to figure out how to do it myself, so I support it with other ,,,).

Not necessarily, there are also telecom users in the north.

If the remaining network cable is too long to form a feeder, it will affect the network speed and is not beautiful to the indoor environment.

1. Cut off a part of the excess feeder to keep the applicability, strip off the two wires with a special connector buckle cap respectively 5mm of the network cable insulation plastic and insert the buckle cap, there is a transverse metal sheet in the movable part of the buckle cap, and then clamp the buckle cap with a wire cutter and hold it hard (amateurs can only operate like this, professionals have special tools), a network cable is connected, and the other one is connected in the same way.

2 There is no special network cable connector buckle cap, can only be operated manually, separate a steel wire pull wire of the network cable and the network cable, keep 10-15cm more steel wire, strip off the wire head of the cut network cable 2cm, twist a wire inside the network cable and a wire of the crystal plug line, and then wrap the network cable with insulating tape, connect it to another in the same way, but ensure the insulation between the two wires:

3. Tightly wrap the excess steel wire around the other end of the network cable connector to strengthen the joint tension and prevent the connector from being disconnected and causing false connections, and then insert the crystal plug into the network cable port of the cat, and you can access the Internet normally.

Generally speaking, the transmission distance of the network cable must be controlled within 100 meters, if the transmission distance of the network cable is more than 100 meters, in order to reduce the packet loss rate, a network cable extender can be added in the middle, so that the transmission distance of the network cable can be extended to about 300 meters, I hope it will help you.

100m requires that the network cable should not exceed 100m. You can run 10m with this network cable. The distance can be a little farther away. If it doesn't work, it won't work, and you can also add a switch within 100M.

Cut off a part of it, there are professional tools, pliers plus tester and crystal head, a set of 30 yuan.

See clearly Khan.

Add a repeater in the middle, a hub, a switch, a router and any of them will do.

It is recommended that you buy a wireless router **It is also very cheap It is available in general computer stores I used to be the same as you, the network cable was dragged around and dragged around It is inconvenient for my mother to do hygiene and I am often scolded for my dog's blood,, It is recommended that you buy it It is much more convenient and the network speed has no effect

You get it and then install an exchanger! That's it! Because I tried! If you don't install it, you can't get it on your laptop, you can only use it on your desktop.

Then buy a connector, a few dollars of things, the distance is more than 100 meters, the signal is a little attenuated, but you can still surf the Internet, and generally don't feel like a problem.

Try it with a wireless router Buy a good wireless router for 100 meters is no problem at all.

What should I do if the network cable is short? Use a network cable to turn a short network cable into a long network cable.

If you need as many meters as you need, you can buy as many meters as you need. Is this still called a problem?I'm dizzy.

Because orange, orange, white, green, and white are normally used downwards, the network cable manufacturer may use a relatively poor line to make blue, blue, white, brown, and white The working signal of the tester is stronger than that of ordinary computers.

Let's see if there's a problem with the quality of the network cable. Generally, the wire diameter of the Category 5e network cable is in between.

Gigabit network cards use 8 wires, and your second case may be the reason.

Hello, the 10m Ethernet cable needs to use 1,3,2,6 numbered cores to transmit data, and the 100M Ethernet cable uses 1-8 to transmit data. If there is one less network, it will be unstable, and the current Windows 7 and Vista systems seem to need 1-8 network cables to connect. You try to connect a good network cable from scratch.

How did you change it, did you change both ends?

In fact, the network cable of 10M Ethernet only uses numbered cores to transmit data, i.e. for sending and receiving, according to the color: orange and white, orange and two for sending;The green, white and green are used to receive and are bidirectional lines.

The 100m and 1000m NICs need to use four pairs of wires, that is, all 8 cores are used to transmit data. Since the 10m network card can use the network cable made in the 100m way;Moreover, the twisted pair cable is provided with four pairs of wires, so it is no longer distinguished in daily life, and the 10m network card is generally made in the 100m way.

Is there a weak signal on the network cable?He relies on electricity to propagate signals and does not weaken. If you are afraid of weakness, you can use a fiber optic transceiver with a fiber optic cable, but the cost is high.

I am a dealer, I recently entered two boxes of engineering super five types of pure copper network cables in Chengdu, the actual measurement can be put on 180 meters without attenuation, so this friend still has to go to the computer city to buy a better network cable.

The network cable transmits 100m bandwidth, only 1236 lines, the simple way is to follow any color, 1236 pass is OK

I can use it when I pick it up, and I can still use it when I'm all broken.
