Worth buying fake encyclopedia, also talk about home router articles four: cable is still necessary DIY

Foreword

We talked about the basics of IP, routing table and DNS, WiFi knowledge (<-click to look back). I believe many value-friends have learned some principles and modes of home network and the role of home routers in home network. Some valued friends commented, "Say so much, you tell me which router to buy is best". I cannot answer this question, at least not a few sentences can answer it. The purpose of writing this series is to let the valued friends themselves Being able to assess my own network needs and tell myself which router to buy is suitable. I dare not claim to “grant people to fish” and I can help worthy friends. I’m not wasting my time. (Of course, gold coins are another reward Things ~ only strange.) Someone who had a problem with the Internet someday, come back and see if the articles in the collection can be solved?

Here we talk about the network cable. Although the network cable has no impact on the choice of routers, but whether the router can work normally in value-friends' "Internet home" is often not related to the network cable. Unless otherwise specified, this article discusses the network cable. It is not qualified to be qualified.


A simple understanding 1. The network cable is the wired medium of two network devices. It is actually a wire.

The power cord used in peacetime, the mobile data cable is one thing! The essence is that the plastic sheath wraps multiple (bundle) oxygen-free copper wires (other wires are not discussed in this article). The power cord is two, the mobile data cable It is 2.0/4 root 3.x/8, network cable is 2~8.


The thicker the core is, the better, the same single root is better than a bunch of ones. It's simple, it's not mystery at all. (Complex, I can't say it)
The pvc skin is generally printed with the manufacturer's name, wire standard (eg 24awg), cable specification (eg cat5e).

2. Today, the mainstream of home network cables are two types, five types and six types.

> The line thickness comparison is five types of


> The current cat6 price is not much more expensive than cat5e, and the average cost of buying is more than 2 meters. It is highly recommended to use cat6 for new shop or new network cable.


> "Ultra-Five is mainly used for 100 megabits, and Gigabit is relatively unreliable." This statement is not correct. In everyday life, I often see super-five runs that are unsatisfactorily gigabytes. That is because there are too many substandard network cables in the country. General renovation of the master package material to buy the network cable and buy decoration finished product room with the network cable are cheap inferior line. Reason 1 is to reduce costs, 2 is 99.9% of the value of the friends did not read this article, when the decoration did not Pay attention to the quality of the cable. When you see the classmates here, quickly find the genuine cable edge material. Go home and compare with the home network cable (is it not being pitted?)


> Good quality cat5 can barely run Gigabit, you read it right! And cat5e's upper limit speed is not Gigabit too, can run 5 Gigabytes within 100 meters according to the new 2.5/5GE standard! I used to think why The megabyte goes directly to 10Gb. Why is the 2Gb 5Gb skipped? At present, SSD and WiFi are stuck on the bottleneck of Gigabit Ethernet, and 10Gb is too expensive. Why not compromise the standards and products to meet the market? What?

Oh, and then there is then. Currently supporting this 2.5/5GE device (it seems to call "multiple gigabytes") rarely, I found several

> The main difference between the five lines and the six lines is the thickness of the core (more visible) and the presence or absence of a cross


Purchase suggestion

1. Which cat5/5e/6/6a do you buy? Of course cat6
> cat5 out of date
> old cat5e continue to use, new buy is not recommended to buy
> cat6a is too thick and hard, it is inconvenient to use it at ordinary times, it is difficult to pull out the pipe inside the wall
> cat6e is not a cable standard. It is printed by the manufacturer itself. The performance is between cat6/6a. Because it is not a standard, it is better than cat6. Ordinary users cannot try it out in the current gigabit network. So if Are you more expensive than cat6 or don't buy it...

2. Do you buy a finished product line or your own DIY? Don't care that the price does not require the length to buy the finished product line (what else is worth buying?), I really don't say anything.
In addition to buying DIY cables and crystal heads, they also need crimping pliers, cutting pliers (scissors are also OK), and the panel may also have a line inserter (there is no panel to buy).
The following links are for reference only and are not recommended for direct purchase (since there is no price issue, there are also confiscated strong brother tips)

Pro'skit CP-3140 type 110 terminal board pressure line telephone / network / module wiring frame wiring pliers 105 yuan wire pliers (cable panel is not free to have to buy) pay attention to safety, this goods Easy to hurt fingers! Jingdong to buy Siemens switch socket panel weak electrical outlet vision series James White a computer network cable socket 45.1 yuan to play the panel, each time pressure 1-2 root, 8 root difficult. Jingdong to buy

3. Buy a round line or a flat line? Non-Virgo non-designed straight men must buy a round line. Others love it.
This question caused me to play "Is the rice noodles to eat round or eat flat?". Flat cable does not meet the standard of the cable, its appearance fully reflects what I said earlier "in fact is the wire". 8 24~26awg of the line package Together can be used when cat5e, what twisted interference prevention is not important, good-looking appearance of the first other aspects can be used on the line. (In addition, I eat flat rice flour,

4. Does the crystal head need to buy six types? Of course, the six-type line buys six types of heads.
The six types of cores are obviously thicker than those of the five types. The six types of crystal heads will have 8 lines of 2 layers. Do not buy the wrong one. Otherwise...

5. Crystal head jacket to buy it? Strongly recommended to buy!
Reduce the chances of pulling the core out when you dial the cable. The type 6 jacket is bigger than the five types. Make sure to say the size of the seller when buying.

6. What kind of cable panel to buy? Buy ordinary, do not need to buy a special label of "six categories".
Choose a regular brand to buy a cheap one, because the main difference is the price!
It seems that all the products on the market are free to fight, and you can dispense with a wire cutter.
With regard to the 86 panel, one thing is to sell dozens of times at ordinary times, and one to engage in three activities of ten dollars.


How to make it (Because there is no material at hand, this part will be transferred to others) 1. Crystal head production Renovation note: My electrician dropped the cable and ran away. There was no way but to decorate the house and bought a 300-meter daily six-wire cable. The panel terminal on the daily line also bought a set of thread-breaking tools. He planned to renovate the remaining cable. Can be self-sufficient for jumpers. On the day I received the courier, I sent a circle of friends and said that I was preparing for a part-time cabling engineer. This would like to install a force to run, did not expect a word into a success, the entire Qingming small holiday in the site hard to do network cable crystal head Taiwan Donglin Gigabit network crystal head six crystal head cable crystal head national shipping Taiwan ..幽幽水葫芦 | Likes 79 Comments 152 Favourites 871 View Details
2. Panel (network cable module production)

The transformation of old things in the home: The old telephone line was changed to the panel AP+ network port. It was recently painful. So we planned to upgrade the home wireless network from the original centralized AP to distributed AP. The advantage is that the distributed AP signal distribution is more uniform. More reasonable, the transmit power can be smaller. The idea is to install a panel AP in the main activity area: the master bedroom and the study (not on the same floor). The living room continues to use the wireless signal of the cat. The original high power wireless router RB951G stopped without (previously located in the stairwell, 1W power spututs_gzb| Likes 93 Comments 97 Favorites 740 View Details

About wiring

1. The weak box must be bought in large size to ensure that the cat + switch + cable tray can be installed.
2. Pull at least one website per room, and pull at least 2 in the living room TV cabinet. If possible, pull 2 ​​in each room, 3 in the study (if there is nas), and 1 in the bathroom and kitchen. If you want We put one monitor (the power cord together) on the ceiling outside the entrance and the entrance outside the entrance.
3. Multi-storey residences are recommended to have a cable and power cord at the ceiling of each walkway (that is, at a minimum position relative to the walls of each room). In the future, it will most likely be necessary to install a ceiling-mounted AP.
4. If you want to share the network with your neighbors and you have a long distance, you can try to pull the fiber. See the last page.


to sum up

After writing this article, I basically spread the hard and soft knowledge related to home routers. In the following chapters, we will talk about the router's firmware system and common program "plug-ins?"
