How to make the broadband network speed at home faster (router signal enhancement coup)

In the past few years, innovative technologies such as SD-WAN, Wi-Fi 6 and 5G have enabled our current network to do more things, but it has also made the network more heavy and complex.

If it is not set properly, in fact, complex networks will aggravate the slowdown of network speed. So many people say that the more complex the network, the higher the requirements for network engineers.

For example, in Huawei certification, for HCIA- junior network engineers, HCIP- senior network engineers and HCIE- network experts, their simplest division is that the networks they are responsible for and handle are different in scale.

The higher the level, the stronger the ability, and the larger the network scope you can be responsible for. Therefore, optimizing the network and improving the network speed are also the basic skills of web workers.

So, is the internet speed of every netizen fast enough to go home? Not exactly.

Generally speaking, there are two ways for home network devices to connect to the network. One is wired, such as a desktop computer, and the other is wireless Wi-Fi, such as a mobile phone.

In these two ways, in addition to the mobile terminal used, the intermediate transmission process will also include the blessing of operators, optical cats, network cables, routers, switches, gateways and other equipment.

Any problem in the middle will affect your final online experience.

Today we will talk about how to optimize the home network and improve the network speed.

0 1 Know your home network environment.

Understand the network environment at home before optimization, otherwise it is useless to equip any equipment.

Is it 20M or 200M?

If you want to choose Gigabit network, you should also consider whether routers, network cables and network cards support it. Otherwise, even if the expressway is built, it will be the effect of driving a tractor on the road.

In terms of hardware, you can consider these.

Home wired networking mainly includes optical cats, routers, network cables and network cards. Generally speaking, devices basically support 100 megabits of bandwidth.

If you use 200M or 500M or even Gigabit bandwidth, you need to check whether the purchased router, network cable and network card support it.

When buying hardware, on the one hand, we should ensure that the hardware supports the highest bandwidth, and whether there is room for future bandwidth upgrade.

On the other hand, make full use of hardware and don't invest too much, otherwise it is equivalent to buying a sports car and running on a dirt road.

Among them, the network cable is the easiest and most easily overlooked medium. Like routers, network cables have different transmission rates. In our daily life, there are five types of cables and six types of cables. The transmission rate of Category 5 cable is 1000Mbps/s, that is, 12.5MB/s, while that of Category 6 cable is1000 Mbps.

If your home Internet bandwidth exceeds 100 megabytes, please be sure to use Category 6 lines.

In terms of software, you have to do this.

The first step is to check the router configuration, which can be optimized by the following methods.

0 1 turn on UPnP

Universal Plug and Play is a set of network protocols introduced by UPnP Forum.

The goal of this protocol is to seamlessly connect various devices in home network and enterprise network, and simplify the implementation of related networks.

Although we have handled the bandwidth of100M, the download speed can actually reach the theoretical maximum.

At this time, you can try to turn on the UPnP function of the router, and let the internet devices directly connect to the external network through port mapping, thus reducing the performance loss in the local area network and improving the download speed. Log in to the router management background and find an option quotUPnP settings quot. In the forwarding rule, port mapping or advanced settings menu, set it to quot in quot status, and then try to see if the download speed is improved.

02QoS and network speed limit

If some devices in the LAN are frequently downloaded by Thunder, it will affect other devices' online access and game experience. This problem can be solved by QoS and network speed restrictions. In the management background of the router, find and open the QoS settings. After it is turned on, the router can automatically and reasonably distribute the traffic to the required internet devices, thus avoiding the network congestion of the whole LAN.

Some routers will provide speed limit function based on IP or MAC address, which can limit the maximum download and upload bandwidth when the device is turned on.

But if it is turned on, it will increase the complexity of router traffic allocation rules and bring some performance loss.

So generally speaking, if you and other people who use broadband have no deep hatred, it # 039 is best not to turn on the speed limit function of IP network, and only use QoS.

03 using router switching mode

When there are many networking devices and the network coverage area is large, it is usually necessary to set up a subnet. The "switching mode" access method using routers will be superior to the ordinary "LAN-WAN cascade" access method.

When using quot switching mode, you should pay attention to connecting the computer to router B alone, and make the following settings: log in to the management background of router B, turn off DHCP service, and avoid IP conflicts caused by opening multiple DHCP servers;

Change the IP allocation method of router B to automatic allocation.

Using wireless relay to expand Wi-Fi signal

Generally speaking, putting the wireless router in the middle of the house can achieve the best signal coverage.

However, if the signal is not strong in some areas, it is necessary to increase wireless routers or wireless repeaters to expand the coverage of Wi-Fi.

When the wireless Wi-Fi signal can cover point B, a wireless repeater can be deployed within the range covered by Wi-Fi to achieve the effect of signal expansion, thus relaying the signal to point B ... Most routers have wireless relay function, and the configuration mode is relatively simple.

In the wireless network settings in the router management background, turn on quot wireless relay quot mode, scan the Wi-Fi signal to be relayed, and then check and enter the Wi-Fi password to successfully expand.

Because the setting methods of different router manufacturers are very different, please set them yourself.

05 static IP address binding

By default, the router uses DHCP for dynamic IP allocation, so if there is a newly connected terminal, it will automatically assign an IP to its MAC address.

In order to reduce the pressure on the router, we can open the binding of IP address and MAC address.

There is no network cable software, and there is no need to set it up, so it is mainly to purchase and make the crystal head firm.

04 terminal side, you should optimize it like this.

0 1 Open static IP

If your computer dynamically obtains IP, but it will cause a little performance loss every time, you can directly specify a fixed IP, gateway and DNS server in the network settings. DNS servers are generally filled in with DNS servers designated by network operators.

Set the full-duplex mode of the network card.

Full duplex and half duplex modes. The difference between the two modes is that, for example, there are two roads, and one road has two lanes, which can travel in both directions without affecting each other;

The other road has only one lane, so two cars can pass at the same time, and the other interactive car can only pass.

In practical applications, walkie-talkies and telephones are both examples of half-duplex and full-duplex.

Set the mode of downloading software reasonably.

Now download software can set download optimization or webpage priority, which can be set according to your own needs.

Generally speaking, our computers don't. T you don't need to transfer files through LAN, you can turn off the network access function, and its existence will slow down the startup speed of the system.
