Ask a question about the network cable to know if it s a network cable problem or what

The cost of using fiber optic cables is too high, and it requires special equipment, which is not as simple as connecting network cables.

Recommended: I have personally experienced the solution of using network extenders. I was at a position of 200 meters to add the extender.

If you don't add it, the network won't work. When you have this kind of problem to solve, you can measure the wiring you want to use first, and then test it at home before wiring. Regarding this Ethernet extender, there are many brands on the market, as well as Olink's and so on, and you should pay attention to the quality when purchasing.

Choose the right one for you! In addition, this long-distance wiring should try to choose a network cable with a thick wire diameter, and if it is outdoors, you can try to choose some five types of rain and lightning protection outdoor network cables, which will have a better effect and are more durable

Aito Ethernet extender is developed using the latest Ethernet long-line drive technology, and the advantages of this technology are reflected in long-distance transmission. Research tests have shown that the use of an Aito Ethernet extender can make a 10m 100m Ethernet full-duplex rate transmission up to 700 meters; By using two Aito network extenders in series, the transmission distance can easily reach more than 1,000 meters. In addition, it can be easily interconnected with switches, hubs, routers, and network cards for long distances, so that the signal will not be lost due to signal failure when the signal is transmitted over a long distance.

You can go to the Internet to check it**, if it is 180 yuan, it should be very cost-effective, and the Internet fee saved for you every year is not this amount.

**Correlation.

Use a network cable to ** line on the line.

The network cable doesn't seem to work, and the transmission of various network cables is not the same in distance, so I think I can only use ** line! Besides, the network cable of more than 300 meters is not cheap!

The network cable is best used to meet the standard, and we generally use Phoenix.

A fork is displayed in the lower right corner of the computer (local connections show a fork).

There is only one case, and the line is not working!!

It may be that the crystal head is not done well, or it may be that the line is damaged. However, it is more likely that the crystal head is loose. You should first redo the crystal heads at both ends of the line, if it doesn't work, it's a problem with the line.

1. I look at his computer in the light of the router even if it is turned off, it is dim and bright, and the general computer turns on the light and shows that it is bright, and it is dark when it is turned off.

Yes, if the computer is turned on, the light on the router will be on, and the light of the network card of his computer will also be on, if it is not on, it proves that the network card has not received the signal, and it proves that there is a problem with the crystal head or a problem with the wire.

2. I've tried changing other sockets, and it's the same.

This proves to be a line problem. Do what I said above.

Note: It cannot be caused by a computer virus, nor can it be a system problem. If there is a fork, it must be a line or crystal head problem, you are upstairs and downstairs, it will not exceed 100 meters. The normal 150-meter network cable will not run out of signal).

This is caused by an incorrect network interface connection.

The WAN port of the router is the home line interface of the broadband, so the correct connection method is:

The optical cable provided by the broadband service provider connects the cat, and the network cable of the cat is plugged into the WAN port of the wireless router, and the LAN port of the wireless router is used to connect to the computer host.

1, 36 is not passable, 78 can be replaced by 78 at both ends.

2. Local connection X, means that the network connection is not connected, hardware, focus on checking the network cable crystal head. Error 678 is a broadband connection failure**, if you are connected to a router, then, this ** indicates that the broadband connection is interfering with the local connection. If you connect to the cat, 678 is most likely a telecom room failure, of course, the network card is bad, the cat is broken, it is all 678,.

3. The original intention of the network twisted pair is to use the stranded wire to counteract the external and its own electromagnetic interference, and you now replace it with 78, which has destroyed its own resistance.

4.These four pairs of wires are all the same lines, but it is better not to replace them, because the original line sequence is resistant to electromagnetic interference.

5. No matter how you connect, more than one computer must have a switch or router to access the Internet, and a router must be used to connect to the external network. Otherwise, you will not be able to access the Internet.

If you want to connect the light bulb, you can't wire it, and the network cable of the two computers must not be directly connected to the same network cable.

6.It is impossible to have no impact, but it is negligible. Unless the network cable is not only thin but also wire.

Seek satisfaction.

Buy a data card, wireless.

If you want to access the Internet, you need to connect to a telecom operator, and the telecom operator provides two ways: wired broadband and wireless Internet access.

1. Wired methods, such as telecommunications, Netcom (Unicom), and Tietong (China Mobile) ADSL broadband are connected through the first line, which is also the current mainstream method. There is also a fiber optic dedicated line connection, which is generally used in this way for new communities and units.

2. Wireless Internet access. Fenghe mobile phone Internet access is a typical wireless Internet access, divided into 2G and 3G, of course, 3G is much faster than 2G. This kind also has a special Internet data card, which can be plugged into the computer, but the price is not generally expensive, and the 1G traffic is generally about 100.

3. At present, all cities are building wifi wireless networks, some of which are built by units, and some are built by traditional telecom operators, which are also wireless methods, but there is no stability of fixed networks, and the speed and cost are between 1 and 2 above.

Conclusion: Judging from your problem description, your home does not have the conditions for fixed-line access, you want to install a wireless landline, and then access the Internet through the wireless landline. The network used by the wireless landline is the mobile phone 2G and 3G network, 2G is definitely not good, the speed is too slow, you will definitely not be satisfied with the computer use.

The speed of 3G is basically the same as that of 2M ADSL, and as mentioned above, the cost is unaffordable for ordinary people. So you want to use a wireless landline to surf the Internet, the idea is not too silvery to dig into reality. Except, of course, if not bad money.

Suggestion: Or find Telecom Live Unicom to pull ADSL, no ** line is not a problem, they will wire the network!

Then choose the 3G network of wireless Internet access to talk about it, the telecom business hall has business, divided into a variety of **, you can go to the year to consult, but ** will definitely be more noble than ADSL Internet.

First of all, the transmission distance of the network cable is limited, the transmission limit of the five types of network cable is about 100 meters, after 1 transfer, it will be reduced to 70 80 meters, more than this length is basically not passable.

Secondly, the same network cable, have you tried it with a hole or other notebooks? Check the 8 needles in the network cable port of your laptop for any deformation and rust.

Finally, if the trembling limb is conditional, replace it with a six-type network cable, pinch off the crystal head outside, and use a cable to connect the 8 wires directly, and the signal can be better.
