An article to help you get the whole house WIFI! Super detailed Mesh home networking tutorial

Hello everyone, I'm a craftsman. At present, with the improvement of living standards, the housing area of ​​some families is getting larger and larger, which makes the WIFI network coverage in the house a problem. It may be visible to the naked eye that the network signal decreases from the bedroom to the toilet. So how to solve this problem? Today, I will give you a brief introduction to the wireless coverage networking technology. First of all, there are currently two types of wireless networking: AC+AP and Mesh networking. Today we introduce Mesh networking online. Mesh networking is relatively flexible and easy to set up, especially in the case where it is not worthwhile to have no network cables before, and wireless Mesh has basically become the only option for the infinite expansion of the finely decorated house in the later stage. Then what is Mesh technology? From the basic definition, Mesh technology is just like its meaning: mesh, which means that all nodes in the network are connected to each other, and each node links at least two other nodes, and all nodes form a whole network. When you use Mesh networking, a mesh network is generated. In this network, the SSID is unified, and the wireless device can find the node area link with the best signal. The user's handheld device shuttles between different nodes, and the wireless network is switched seamlessly. The data packet loss and delay in this process are lower. The better the network. From the above, we can learn several characteristics of Mesh networking: unified wireless name, unified network management, convenient addition of nodes, and support for multiple networking methods (wired, wireless, and hybrid). Next, let's talk about some things to pay attention to when you use Mesh networking:
  • All applicable router firmware versions must be the same, and the firmware must support the Mesh function.
  • Try to use the same type of router for networking, although different models can be used, but there will be problems such as stability.
  • When using wireless backhaul, the distance between routers should be as close as possible, no more than 2 walls at most.
  • If it is a duplex cross-floor networking, try to use wired connections. If you use wireless, try to place the devices at the entrance of the stairs to reduce obstacles caused by floor partitions and floor heating.
  • Wired backhaul is best if the main route and the sub-route are directly connected to reduce compatibility problems caused by switches.
  • Wireless Mesh Networking Wireless Mesh is the easiest way, and it is also the only option without deploying network cables. But the signal strength is weaker than wired. The influence of wireless backhaul mainly has the following two points: dual-band tri-band and router distance We generally recommend tri-band routers for wireless networking, because if dual-band is used, router nodes will share a 5G frequency band with mobile devices when transmitting. , the network speed has a greater impact. However, for tri-band routers, there is a dedicated frequency band between nodes for networking, and the network speed of the terminal connection has no effect. Wireless experience is better. And after networking, there are still two frequency bands available for users to use. Secondly, the experience of wireless mesh networking is closely related to the number of nodes. The link quality between nodes is related to the distance between nodes and the number of walls passing through. Therefore, it is not recommended that two nodes need to pass through more than one wall (the distance does not exceed 10M). Wireless networking method: basically follow the manufacturer's instructions: first, update all routers to the latest firmware version, then power on the main router, and configure the Internet normally. Then use a browser to access the IP address, log in to the background, and add a Mesh node on the management page. This is in the promoter route, where the search is added. After the addition is complete, you can place the sub-routes in the desired location and start up. Wired Mesh networking is the most ideal networking method at present, with the most stable network quality and the lowest requirements for routers, and the wireless network speed is almost not attenuated. Wired backhaul requires network cables to be deployed in advance to link all routers. Therefore, using wired mesh networking requires network planning, deployment of network cables, and electrical ports at the connection ports. Do not connect the network cable directly before wired networking. You need to perform wireless mesh networking first, and then connect the network cable after completion. Things to pay attention to: The most recommended wired mesh is that the main and sub routers are directly connected to the network cable. We must first close the DHCP service of the optical modem itself, which is the basis for the subsequent operations. After the optical modem is changed to bridge mode, the network configuration can be more flexible. And because the performance of the optical cat is generally weak at present, this operation can also improve the network performance to a certain extent. Next, I will briefly talk about the following methods:
  • The network cables are gathered in the non-weak current box position
  • This is an ideal solution. In this case, the optical cat bridge is optional. The dial mode of the light cat can be maintained unchanged. Using a Mesh router as the main route, the weak current box only has a light cat, and the network cables are concentrated in the living room. The switch is only used as the main routing port, and there is no mandatory requirement. In the case of a small number of sub-routes, it can also be directly connected to the main route. If the area is large and more devices are required, you can add a gigabit switch, connect the main route to the switch, and then lead out other network cables from the switch. The optical modem is changed to bridge mode and dialed by the main router, if not, it can not be changed. 2. The network cables are gathered at the position of the weak current box, which is generally used for more installations. The network cables in all rooms are converged to the weak current box. In this case, a number of different schemes can be used depending on the specific situation. ①: There are replaceable network cables. In this case, we lead three network cables from the weak current box to the living room. If there is no need for IPTV, it can be changed to two. One is connected to IPTV (nothing can be ignored), one is connected to the WAN port of the main router, then the other is connected to the LAN port of the main router, and then the network cable is connected to the switch 1 in the weak current box, and the other network cables are connected to the switch. First perform wireless mesh networking, and then take the sub-router to other rooms and plug in the Internet cable. ②: Single-line multiplexing Mesh networking + IPTV optical modem is set to bridge mode, and the DHCP function is disabled. If this premise cannot be met, this method cannot be used. In this case, 2 gigabit switches are required, and the VLAN function of the switches needs to be used to separate the IPTV data from the Internet data. This method has higher network requirements. The switch has a management IP address by default. When there are two network management switches in the network, you need to modify the default management IP address to prevent network device IP conflicts. Divide the IPTV interface into one VLAN, and divide the router's Internet data interface into another VLAN. The two do not communicate with each other. Setting VLAN may be too complicated for Xiaobai, you can use the following AP mode solution. AP mode Mesh networking In this mode, a soft route is required as the main route. If the requirements are not high, an optical modem can also be used. Other mesh routers only provide wireless functions. At this time, the mesh router needs to be downgraded to network through AP mode. In AP mode, all routers only support wireless functions, and some high-end functions such as firewall will not be available. Mesh settings in AP mode are relatively simple and easy to operate. For example, if the soft route IP is 192.168.2.1, we will adjust the Mesh main route to 192.168.2.2. Then perform wireless Mesh networking, and close the main route DHCP after success. Switches can be omitted according to their actual needs. If there is no soft route, you also need to use AP mode, connect the optical modem to the switch, connect the sub-router to the switch, and the optical modem is responsible for dialing and gateway. However, the performance of optical cats is generally weak. If the demand is not particularly high, this method can be considered. The above are several Mesh networking solutions. We summarize it as follows:
  • The simplest solution is to deploy multiple network cables and concentrate the network cables outside the weak current box. In the place of the network cable machine, the space should be as large as possible, so that there is no need for too many equipment and network technology, only the connection line is required, and the later expansion is relatively flexible.
  • The weak current box deploys 3 network cables to the living room, and the network cables of other rooms are connected to the weak current box. In this case, a gigabit switch needs to be installed in the weak current box.
  • All network cables are concentrated in the weak current box, and one network cable is sent from the weak current box to the living room, and needs to support IPTV and Mesh networking. 2 switches with network management function are required. This method is complicated to set up, requires professional network knowledge, and requires high hands-on ability. The optical cat can contact the operator to change the bridge mode.
  • The above are several Mesh networking solutions introduced to you today, I hope to help friends who are considering new house decoration and old house renovation some help in network formation.
