No more WiFi signal dead ends at home!

  What do you do when there is a blind spot or blind spot in the WiFi signal on the home network? Constantly adjust where you use your mobile phone or computer, buy a power cat or WiFi signal amplifier? Whole-house network coverage is the inner desire of many home users. In the face of various whole-house coverage schemes in the market such as power cat, AP, and Mesh, how should we choose?
  Home Basic network environment is very important
  speed is not fast enough, the signal is not good enough …… when we started to complain about the home network operator, routers and even terminal equipment are likely to be back pan Xia, the problem is that many people ignore the home network Wiring, this is the cornerstone of all applications. With the development of the future 5G mobile network technology, the continuous improvement of the network bandwidth of operators and the introduction of the latest WiFi 6 network standard, the design standards for the network also need to be continuously improved. In general small and medium-sized network systems, in addition to the access equipment of telecommunications operators (optical fiber modems, ADSL modems, etc.), only one main wireless router is installed (that is, used as a router and a switch). If the wireless network coverage is insufficient, A wireless router (used as a wireless AP, and the software is set to AP function) or a wireless extender will be used as a wireless signal extension device. The two wireless routers can be connected through wired or wireless bridge Way to connect.
  This kind of network system structure is very simple and mainly depends on the quality of wireless routers. Now mainstream wireless routers use IEEE 802.11Ac technology to provide 2.4GHz and 5GHz frequency band signals, 2.4GHz frequency band, wireless speed can reach 450Mbps; 5GHz Frequency band, the wireless rate can reach 1300Mbps or higher, and the 5GHz frequency band can access more wireless terminals, with less interference and fast speed.
  In a large-sized network system, according to the selection of various network products, the network wiring method of the room, and the capital budget, there are various network architecture deformations. The traditional single high-power wireless router will certainly not cover each room, which will cause signal blind spots. And the signal quality is unstable, and with the popularity of AC+AP network equipment, it is now recommended to use the above network architecture for large-sized houses.
  The POE router has a built-in AC controller, which can manage wireless APs in each room in a unified manner. A general home POE router has 4 POE Gigabit Ethernet ports built in, which can connect up to 4 wireless APs. If the house’s wired network ports also exceed 4 One, then you need to equip another gigabit network switch. In order to meet the needs of high-definition video, audio and video, the entire core data exchange layer is all gigabit network. If you are some video workers, you need to frequently copy in computers and NAS. Video files, now there are 10 Gigabit switches available for use at home, and Gigabit networks in general home networks can meet the demand at this stage. Using professional wireless AP for WiFi coverage, the effect and experience will be much higher. In addition, for newly renovated families, cables have to choose Super Category 5 cables and above to lay the foundation for future 10 Gigabit networks. After completing the home network layout, if you want to achieve no coverage, you still have to rely on different network construction solutions.
  The actual manipulation of very troublesome bridge
  router wireless bridging function, a radio signal is through the two routers connected together to achieve delivery network from one location to another location, in order to achieve a wider coverage radio signal.
  In order to use a wireless router to expand the coverage of wireless signals, the wireless router first needs to have the “WDS wireless bridging” function. When using it, first make sure that the main wireless router A is powered on (the router connected to the telecom operator’s network cable) and can access the Internet normally. At the same time, make sure that the bridge router B is within the wireless signal coverage of the main route A. Next, turn on the power of router B, first enter the setting interface of bridging route B, modify its IP address to the same network segment as the main route A but not overlapping IP address. If the IP addresses overlap, our wireless bridging work will fail due to the wrong IP address. This is very important and critical. For example, the main router is set to the network segment of, we can set router B to the network segment of, and then we can enter the setting page of WDS wireless bridge. Now the wireless router WDS wireless bridging function is very complete, and the operation setting method is also very user-friendly. We only need to click “wireless relay” in the network settings to enter the menu, and connect to router A like a wireless network connection router. Okay. In other words, you only need to scan out the network name (SSID) of the main route A in the bridge route B, then select the network name of the main route A, enter the correct password, and click connect to complete the bridge work. Next, both routers A and B should work normally. Of course, if necessary, you can enter the wireless setting interface of router B to set the SSID name and wireless connection password and other information.
  AC+AP networking can also be used in homes.
  AC+AP networking is generally used in enterprises/hotels/public places/and villas. AC as the central control unit is responsible for unified and centralized management of all APs, so all management commands and SSIDs are just AC issued, the AP as the access point of the AC is only responsible for accessing the device and cannot work independently.
  Simply put, the AP is equivalent to connecting all wireless network clients together, and then the wireless network is connected to the Ethernet, so as to achieve the purpose of wireless coverage. AC is used to manage APs to achieve the purpose of automatically kicking out weak networks and wireless roaming. AP is actually divided into fatAP and fitAP. The so-called fatAP is a traditional wlan networking solution. FatAP itself undertakes complex functions such as authentication termination, roaming switching, and dynamic key generation. It cannot be managed in a unified manner. The nature of the wireless AP is a fatAP, and it cannot accept the unified centralized management of the SSID by the AC, nor can it achieve seamless roaming. Even if the device is set to a unified SSID, the switching of the device in the fatAP is essentially manual access (don’t be deceived by illusions).
  The AP in the AC+AP networking solution is fitAP, which is an AP with only encryption and radio frequency functions. It has a single function and cannot work independently. Only the fitAP of the same brand as the AC can be controlled by the AC to achieve a truly unified SSID. , Seamless roaming. Now there are three-in-one network equipment of AC controller + poe switch + router. You only need to connect the WAN port to the optical modem and the LAN port to connect to each AP device. This three-in-one device is often not as stable and compatible Perform its duties, and if the high-end router used at home will lose its usefulness, if the weak current box is large enough, it is better to separate it, and the router can also be replaced with a soft router to achieve Internet access, intranet penetration, filter advertising, NAS and other functions , You can also connect N1 soft router or high-end router to flash into the Merlin system to achieve the above functions. Please note that each device must have a Gigabit network port, except for the AC controller, which is only connected to the poe switch , Just control the 100M Ethernet port. Of course, the AC+AP solution is not without its drawbacks. The money cost it requires is relatively high (the heat dissipation problem of some panels is also a pain point). This solution requires at least 2 network cables in the room (open wires) or even Each room has a network cable (this can make the wifi5G in the house run full), which is used to connect to the AP. This is due to the weak wall penetration ability due to the power consumption and shape of the AP. An AP basically cannot fully cover the WiFi 5G.

  Power Cat Power Cat worry scheme
  Cat Power is the use of a unique power line wiring network signal load up, as long as the local power line (meter line within the same range), can communicate with each other, their advantage has gradually been network users Recognized. Especially when the ADSL broadband in the network is upgraded to optical fiber users, it is impossible for the old wiring to be re-arranged due to decoration and other reasons. Then, using the power cat is a more convenient way of wiring.
  Power cats are very different from wireless routers. They usually appear and used in “pairs”, which means they must be purchased in pairs. Don’t think that power cats are not doing business properly. In fact, their maximum transmission speed is OK. It reaches 1200Mbps, which is faster than some network cables.
  Of course, it should be noted that the power cat has the difference between wired and wireless, namely “wired power cat” and “wireless power cat” two types. “Wired power cat” means that after the power cat is deployed, computers, TVs and other equipment need a network cable to connect to the power cat to be able to go online normally. The “wireless power cat” is developed on the basis of the “wired power cat”. After the deployment is completed, the Internet can be accessed through a method similar to a wireless router.
  The deployment of power cats is simpler, just add them to the power socket at home, and then connect the network cable to complete the network configuration. In detail: the first step is to plug Power Cat A into the socket of the wireless router, and then connect the LAN interface of the wireless router to the network interface of Power Cat A through a network cable. The second step is to connect the power cat B to the socket of the room where the network is to be covered, and the network can be used normally later.
  Mesh and power cat can play with
  large size wireless extension embodiment, a scheme is outstanding can be regarded by the power cat power line transmission of the data signals and media. With the change of technology, the combination of Mesh and PLC power line communication, combined with the functions of Mesh and power cat, is switched according to the actual situation of different application scenarios, and is also deeply loved by the market.
  Huawei Q2 is such a product. The device not only has 5GHzMesh technology with 867Mbps bandwidth, but also supports power line transmission with 1000Mbps bandwidth. A main router can connect to up to 15 extended routers. Mesh+ power cat, a two-pronged solution is currently considered to be the perfect one among large-sized wireless solutions.
  Mesh into the mainstream market programs
  with different traditional wireless network, the wireless network AP Mesh wireless connection may be employed for interconnection and inter-AP can establish multi-hop wireless link, the current network has been widely used Mesh Many areas.
  Mesh is a wireless grid, which is developed from Ad Hoc network, belongs to “multihop” network, and is one of the key technologies to solve the “last mile” problem. Wireless Mesh can communicate with other networks, and any two Mesh devices can maintain wireless interconnection.
  In fact, a Mesh router, which is what we call a distributed router, is generally composed of two routers, so it is also called a parent-child router. What the Mesh router generates is a kind of mesh network. In this network, different devices and different access points can be mixed in star, tree, series, and bus modes, so that wireless devices can be in this range. It automatically finds the best device and performs intelligent switching, so the Mesh router can cover a large area of ​​WiFi signal.
  Compared with the traditional multi-wireless router relay solution, the advantages of the distributed wireless router using Mesh technology are mainly reflected in these aspects: First, the installation and operation of the distributed wireless router is very simple, and the user only needs to set the main router to go online. After the method, network name, and network encryption, power on the extended router. The whole package will only generate one SSID, no need to connect manually. Secondly, since the expansion router can not only connect with the main router, but also with other expansion routers. There are multiple connection channels between any two nodes, so the expansion router will automatically select the one with the best signal from the surrounding routers. Perform networking. When you use your mobile device to use the network in different locations at home, the Mesh system will automatically switch to the network with the best signal according to the monitored signal strength, so that players can get the best online experience.
  The network coverage area using distributed wireless routers is very large, usually 1 main router + 2 expansion routers can achieve the network coverage of 600m? villa, which is beyond the reach of traditional relay solutions.
  Mesh should be elected WiFi 6 camp
  due Mesh characteristics determine its broad market in the domestic field, making various manufacturers scramble cake. Therefore, 90% of router manufacturers have launched Mesh products, whether it is Tplink and Dlink, which are the main cost-effective market, or the glory, Xiaomi, and 360 of Internet manufacturers, and ASUS, NETGEAR, and linksys of established first-tier manufacturers have all launched Mesh products.
  At present, Mesh is mainly divided into three categories, one is dual-frequency Mesh, such as Velop’s 2600M, 3900M version (1300xN) and TP-link 7650, and the other is three-band Mesh, such as the full range of orbi, and Velop’s 4400M, 6600M (2200xN) There is also a power cat plus dual-frequency version, such as Huawei q2pro dual-master version (the mother-child version is not mesh) and Xiaomi Mesh.
  The biggest difference between dual-band and tri-band classification lies in the wireless networking mode. Although Mesh can be used in wired mode networking, consumers buy Mesh for wireless networking in most cases. The effect of AC+AP in wired networking will be better. There is no need to use mesh. In the process of wireless networking, signal transmission between nodes and mobile device signal transmission will compete for resources with each other, which will inevitably lead to a decrease in transmission rate. This is the origin of the full blood version of the Mesh and the residual blood version of the Mesh. The full blood version of Mesh uses a 3-band mode (1 2.4G frequency band + 2 5G frequency bands), of which 2 5G frequency bands are used for node signal transmission and connection to wireless devices, so that the 2 lines each go their own way , There will be no scramble. The entry-level Mesh products all use a dual-frequency mode (1 2.4G frequency band + 1 5G frequency band), and the networking signals between nodes and wireless devices share a frequency band, and the transmission rate has also decreased.
  Therefore, when purchasing Mesh products, in addition to regular information such as hardware and signal coverage, we must also pay attention to whether it is a three-band Mesh.
  The most suitable solution for old brand users to upgrade Asus AiMesh
  may have users who feel that after buying a new set of distributed wireless routers to form a Mesh network, the old wireless routers can only be discarded, which is wasteful. Anyway, it’s all wireless router expansion, so can we use existing products to upgrade? Not to mention that some manufacturers have come up with a solution, this is ASUS AiMesh.
  The highlight of the AiMesh solution is that after purchasing an ASUS wireless router, if there is a need to expand the wireless coverage in the future, you only need to buy another ASUS wireless router according to the actual situation to form an AiMesh system. Of course, the AiMesh system has certain requirements for the product model. Only choose RT-AC1900P, RT-AC68U, RT-AC86U, RT-AC88U, RT-AC5300, ROGRapture GT-AC5300 and other high-end products. Just update the firmware before.
  The advantages of ASUS AiMesh intelligent WiFi network technology are not only excellent performance, but also its cost-effectiveness is also obvious compared with traditional Mesh networking technology. For users who have two or more ASUS routers at home, it is entirely possible to obtain AiMesh functions for free through online firmware upgrades. Even if you need to purchase new ones, the current promotional price of mainstream models such as RT-AC68U 1900M is 479 yuan. The price/performance ratio is already excellent.
  AiMesh will establish a stable “backbone” connection between wireless routers. If there is a problem with one of the routers, AiMesh will identify and use the rest of the wireless routers to repair itself; in an environment with a tri-band wireless router, AiMesh will also select one of the two 5GHz bands for communication between wireless routers . In addition, ASUS AiMesh will continuously monitor the signal strength and switch the device to a better wireless router.
  AiMesh’s intelligence is mainly reflected in router hotspots and frequency band switching. In home WiFi networks, 2.4GHz signals have better wall penetration, but the network transmission performance is weaker than 5GHz; although 5GHz signals have better overall performance, they can pass walls. Relatively weak.
  The characteristics of different network signals often make people feel that it is difficult to have both fish and bear’s paws. In a home WiFi system built with multiple routers, not only the choice of 2.4GHz and 5GHz is faced, but the frequent switching of WiFi nodes in different environments is more It’s a headache.
  ASUS AiMesh can establish a single network name for the whole family, so when users move around the house, they don’t have to manually select a wireless router with better signal strength. AiMesh technology will continuously monitor the signal strength received by the device, and switch to another router with higher signal strength and faster speed as needed. The whole switching process is fast and smooth, without network interruption, and the whole process is completely insensitive. . In general, ASUS AiMesh can be regarded as an upgraded and optimized version of Mesh. With ASUS’s huge product camp in the WiFi 6 routing field, it will be quite good for mid-to-high-end players or upgraded users who are already ASUS routing users. s Choice.
