If you are more concerned about home internet speed and whole-house Wi-Fi coverage, I recommend that you read this article, because many designers do not necessarily understand Wi-Fi-related knowledge.
Once before, when I was on a WeChat voice call with my friend, the voice sounded intermittent, and she said that the Wi-Fi Internet at home should not be so bad. I asked if it was someone in the room and the router in the living room? She said yes. I asked if the router was inside the weak electrical box? She said yes. That's why.
Many families have a router in the whole house, and for aesthetics, they will be placed in the weak current box. Although the Wi-Fi signal on the phone shows full space, the internet speed may actually be very weak.
If you still have some requirements for network speed, don't install it like this, especially if the router doesn't put a weak electrical box. This article will talk about the various implementations of wi-Fi in the whole house, if you feel a little dizzy in the middle, you can directly pull to the bottom to see the summary.
01
Cabinet doors and walls have a big impact on network speed
Q: Do cabinet doors and walls have a big impact on Wi-Fi?
A: Bigger than you think. I looked for data on the Internet, and the 2.4G band is roughly as follows:
There is about 1/2 of the signal left after passing through wooden planks, wooden doors, glass, etc.; about 1/30 of the signal after passing through brick walls; about 1/1000 after passing through a 25cm load-bearing wall; and 1/10,000 left after passing through metal obstacles such as elevators.
Songye: This is a rough theoretical value, in real life will be a little more complicated, but everyone can understand the meaning, that is, the wall facing the Wi-Fi signal blockage is relatively strong, so the router is placed in the center of the house The effect is relatively good. The router is best not to be placed in the weak current box, especially the weak current box lid is generally metal, the signal has a greater impact.

Which is better, 2.4G or 5G?
Q: Which is better, 2.4G or 5G for Wi-Fi?
A: This is about the frequency band, and it has nothing to do with the 5G concept (the fifth generation of mobile communication technology) in 5G mobile phones. The routers on the market are basically dual-band, that is, the 2.4G and 5G bands are available. Just remember a conclusion that the 2.4G band is slow but has a good ability to penetrate the wall; the 5G band is fast but the ability to penetrate the wall is weak.
Songye: Now most routers can be set up dual-band merger, which probably means that the phone itself will automatically choose which frequency to use, you can also separate, and then manually choose the 2.4G Wi-Fi signal or 5G Wi-Fi signal in the mobile phone settings. Sometimes when you encounter some "not so smart" smart home appliances, you can only connect the 2.4G Wi-Fi signal, you can only set the Wi-Fi signal separately.
The 2.4G band is slow and has a good ability to penetrate the wall; the 5G band is fast and the ability to penetrate the wall is weak.
03
Is the King of Walls useful?
Q: Are there any uses like the Wall King, Wi-Fi signal amplifiers, and power cats?
A: Cottage brand routers are often advertised as "king through the wall", and there are many antennas, saying that they have a high power and strong ability to penetrate the wall, but in fact, there is not.
The national standard has restrictions on the power of the router, and the products that exceed the standard cannot be listed, do not believe what is called power. More antennas do not necessarily mean that the signal is better, and now some router antennas are built-in and do not affect the signal.
Wi-Fi signal amplifiers and power cats, from the user evaluation, some people feel useful, some people feel useless, this is because the effect will be affected by various electrical and environmental influences, unstable.
Song Ye: Don't believe the king who walks through the wall. Wi-Fi signal amplifiers and power cats, if there is really no other way, and the Internet access requirements are not so high, you can try.

The most expensive and best plan
In fact, each family's network needs and apartment conditions are different, if the requirements are not too high, the apartment area is not large, on the mobile phone brush WeChat, buy a better router as far as possible in the middle of the house, less shade is enough.
If you have high requirements for internet speed, then it is best to decorate the network cable in every room and space, such as the toilet is also very important (if you go to the toilet and do not take the mobile phone that I did not say), I personally think that the network cable with a six-category or super-six category is almost. Although there are more Wi-Fi for mobile phones and laptops now, the network cable is helpful for the 2 schemes I said later.
1、AC+AP;
2. Mesh router.
The most expensive and best-looking solution is undoubtedly AC+AP.
Q: What is the AC+AP solution? How much does it cost?
A: The AC+AP solution was basically commercial in the past, such as company and shopping mall use, and now high-end residential buildings will also have this solution. The characteristics are: good effect, high price. You need to arrange the network cable in advance, so it is best to consider it when decorating.
AC: The Wireless Controller (Access Controller) is used to centrally manage multiple wireless APs.
AP: The Wireless Access Point is equivalent to a WiFi transceiver.
There are two commonly used APs, one is ceiling-mounted, generally considering the position arrangement when making the ceiling, this coverage is wider, because the probability of being obscured is smaller. There is also a switch panel form, which is more commonly used in the family, because it is easy to arrange, just replace the original network cable interface position with this AP panel on the line.
Specific about how much money I give you a starting price example, first of all, since they have chosen such a high-end way to play, then it must be considering the gigabit network, now the big cities are 300M-500M started, in a few years will certainly grow, our side of the operators are promoting gigabit, so leave gigabit network is to, network cable is at least six types of lines, anyway, each room has left the Internet line.
In addition, take TP-LINK as an example (more common, basic entry, non-proper meal, confiscation of money), four AC is about 300, AP is more than 300, adding up to about 1700, which is probably suitable for larger three-bedroom apartments. If it is a villa with many rooms, the AC of eight mouths is about 700, and each room is equipped with an AP of more than 300 yuan to calculate it. I use this kind of at home, and this year I changed the 1000M network speed to run full.
I'll give you an example, there are many better and more expensive products.
Of course, in addition to some shortcomings of your price, I posted a message from a previous netizen:

The disadvantage of my own home panel AP is that the number is small, and it cannot cover the whole house. I myself have not studied the knowledge of network speed when I first renovated, the AP panel is changed from the location of the network cable panel, and the current kitchen and bathroom network speed is almost useless, maybe next time I will consider using the Mesh router solution.
In addition, the AC+AP program is also quite a test of hands-on ability, networking settings, software upgrades, etc. are very discouraged for ordinary small white users.
Q: What about mesh router solutions? How much does it cost?
A: You can probably understand this as a parent router, that is, it can be understood that several routers can be wirelessly connected together. Suitable for large-area apartments that have been renovated and cannot be changed. Of course, if there is a network cable to do the wired backhaul, the effect will be better!
This solution is much simpler than the AC+AP above, and the price is also cheaper. Mesh router price low end point of about 200 single machine, good single machine hundreds, thousands, thousands have, home to use a few depends on how big the house is.

Song ye summary:
1, about 100 square meters of the house, buy a good point of the router can basically meet, but the router is best not to put in the cabinet, weak current box, as far as possible to reduce the occlusion;
2, large apartments, especially the wall more, if you want to be technically simpler, personally recommend using multiple Mesh router networking;
3, buy a villa must be rich people, directly on the AC + AP program is the best and most beautiful, must be considered in advance when decorating the design.
It is important to act according to the demand, for most families only need to brush the demand for short videos, a good router is enough, do not read this article must engage in AC + AP or Mesh router, it is a bit of a chicken with a cattle knife, the meaning of the city main road running Ferrari.
Additional Notes:
1, home paving network cable must choose more than six types of lines, and it will definitely be a gigabit network in the future;
2, optical cat, router and other various network cable interfaces must also be gigabit interfaces, otherwise it is white;
Finally, to answer the title question, if you have particularly high requirements for network speed, it is recommended that important rooms still have to be buried with network cables, after all, the wiring is more stable. Most families actually only need to consider the network cable from the router location to the location of the optical cat.
I also understand these furs, welcome to the master to add.
