wifi acceleration method

Slow WiFi speed on mobile phones is really annoying. Is there any effective WiFi acceleration method?

Free method one: Change the wireless router Location

Have you put the wireless router and the broadband modem provided by the operator together? In fact, it is not necessary. Although they are all network devices and can be easily managed together, in fact A wireless router should be placed at the center of your wireless activities to provide the best wireless coverage for your wireless applications. (Recommended learning: PHP video tutorial)

Because no matter what brand of wireless router, its effective coverage is limited, ranging from tens of meters to hundreds of meters. Within this range, Wi-Fi performance is relatively fast and stable. But if it exceeds this range, the wireless signal will begin to attenuate. Even if you have a good computer or a powerful wireless terminal, watching online videos through wireless will cause a large delay.

Moreover, by looking at the interference chart of Wi-Fi caused by obstacles in front, it is recommended that when placing the wireless router, avoid the most obstructive objects mentioned above as much as possible to reduce dead spots.

Free method two: change the wireless frequency band or channel

Nowadays, wireless products that support 2.4GHz and 5GHz dual-band are becoming more and more popular. In view of the application in There are not many home-grade wireless devices in the 5GHz band. Users can switch the router to the 5GHz band for use, and the Wi-Fi speed will be significantly improved.

For general 2.4GHz single-band wireless routers, the method of improving Wi-Fi can be by changing the routing wireless channel. Generally, single-band wireless routers divide the frequency band into 11 or 13 channels. If no adjustment is made, the router will use its default channel, which increases the probability of using the same channel, causing wireless signals to conflict and interfere with each other, and reducing the quality of wireless transmission. . At this time, you can use inSSIDer to detect the channel occupancy of the environment.

inSSIDer is a free wireless detection software. You can use it to view the channels used by other wireless signal sources, as shown in the yellow box in the picture above, and then switch to a less crowded channel. Like 8 or 9 on. It should also be noted that the signal of one channel will interfere with two adjacent channels at the same time. That is, the signal of channel 6 will affect channel 5 and channel 7. Therefore, when setting up the wireless channel, we should choose to stay away from other signal sources. There are more than two channels.

Free method three: Upgrade router firmware

Firmware is a control program embedded in the hardware and has an important impact on the performance of the router. Updating the router's firmware is a step that wireless users often overlook. Just like software must be updated regularly, wireless routers also need to check for updates frequently to fix bugs and improve the operating performance of the device. For example, after a firmware update for a certain brand of router, the wireless transmission rate increased by nearly 100 Mbit/s, and the Wi-Fi improved significantly.

Unlike software updates, which are as convenient as software updates, router firmware updates often require searching for updates on the router manufacturer’s website, and then uploading them through the router’s web interface. Although sometimes updating the firmware cannot directly expand the wireless signal, it is quite helpful in improving the stability of the router.

Free method four: Upgrade the wireless adapter firmware

The wireless adapter is a "receiver" that enables computers or mobile terminals to use wireless methods to access the Internet. "(actually also supports transmitting) device, which is matched with a wireless router or wireless AP with wireless transmitting function. A wireless router and wireless adapter must be used together to connect to the wireless network and access the Internet. If the performance of the wireless adapter is weak, it will create a bottleneck for the transmission of the wireless router and cannot exert its best performance.

So, the wireless adapter is also an important "partner" of the wireless router for wireless transmission. In addition to having an excellent wireless router, you must have a matching wireless adapter to ensure good Wireless coverage and transmission performance.

Most laptops use integrated adapters. Taking the Windows operating system as an example, you can enter the management interface of the network settings adapter through the "Control Panel" to find out its name, and then Find the adapter's manufacturer's website to make sure you have the latest firmware.

Free method five: Use third-party firmware

In addition to updating the official firmware for wireless routers, there is also a method commonly known as "flashing" This method can install privately developed third-party firmware for wireless routers, such as Tomato, DD-WRT, OpenWRT, etc.

The above-mentioned third-party firmware can improve the performance of the router, including improving wireless transmission performance, and expanding the function settings of the router to a richer set. But just like PU overclocking, it can give full play to the performance of the router hardware, but it also involves considerable risks.

However, due to the stability of the equipment, most router manufacturers do not support "flashing". Once the "flashing" fails, the warranty is not provided.

Therefore, it is not recommended for users who do not understand third-party firmware, because if you are not careful, your wireless router may be scrapped and turned into bricks. This method is only suitable for professional players.

Economic Method 6: Set up a second router for wireless relay

To use wireless relay for Wi-Fi expansion, you need a second wireless router , this is a simple and fast wireless expansion method. Wireless relay mode can perform point-to-multipoint bridging. While extending the wireless signal transmission distance, wireless routers using wireless relay mode can also accept access from other wireless devices, making the coverage more comprehensive and flexible.

Although using wireless relays can effectively expand wireless signals, the additional relay process will occupy network bandwidth and reduce wireless speeds. Considering the problem of signal loss, if the original network is not fast enough, even if the wireless range is expanded through wireless relay, the speed improvement may not be obvious. And it should be noted that both wireless routers need to support WDS relay mode.

Economic method seven: Upgrade the antenna

Since Wi-Fi signal transmission is sent and received through antennas, there are many on the market Separate booster antenna products allow users to replace the antennas on wireless routers or network cards. Of course, these devices must support the detachability of the antennas.

According to the differences in antenna transmission and reception in the horizontal direction, antennas can be divided into omnidirectional antennas, directional antennas and sector antennas. Omnidirectional antennas can receive signals from all angles in the horizontal direction and radiate signals to all angles. A directional antenna means that the antenna is particularly sensitive to signals coming from a specific direction and the energy is concentrated in a specific direction when transmitting signals. Sector antenna is an antenna that is between directional and omnidirectional.

The dBi on the antenna specifications represents the gain value of the antenna. The higher the gain value, the farther the transceiver capability is at the lateral distance, but the transceiver capability at the vertical distance will be sacrificed. Depending on the indoor environment, signal refraction conditions are also inconsistent, so whether it is an omnidirectional or directional antenna, the antenna angle must still be adjusted to obtain the best wireless network coverage.

Expensive method (8): Deploy dedicated wireless repeaters and extenders

Most wireless routers on the market now have Can be used as a wireless repeater or wireless extender. However, if you use them to extend Wi-Fi signals, the setup may be very cumbersome and tricky, and may not be possible due to compatibility issues.

At this time, for large rooms or LOFT units, it becomes very necessary to deploy dedicated wireless repeaters and expanders. And because it is an exclusive expansion product, it is relatively easy to set up. However, the price of individual wireless repeaters and wireless extenders is generally very expensive, ranging from a few hundred yuan to a thousand yuan. It is recommended that users who are not short of money can choose it.

Expensive method (9): Deploy the latest wireless routers and adapters

In order to obtain a smoother and broader wireless network, you can deploy the latest 802.11ac wireless routers and wireless adapters.

802.11ac products have multiple advantages. In terms of transmission speed and power consumption, the 802.11ac solution can provide 3 times the wireless rate of 802.11n and reduce power consumption to 1/6 of the previous one. . Secondly, in terms of spectrum used, 802.11ac uses the 80/160MHz channel, which expands the bandwidth by 4 times. At the same time, the higher-speed 256 QAM modulation scheme is used to achieve high-efficiency data transmission and reduce energy consumption. And 802.11ac uses beamforming technology to achieve higher reliability, longer transmission distance and greater coverage.

Therefore, users can choose matching 802.11ac wireless products to obtain a faster and wider wireless network.

Expensive method (10): Customize proprietary wireless solutions from manufacturers

For villa-level users, if the above methods still cannot satisfy For your wireless coverage and transmission needs, in addition to purchasing dedicated wireless expansion equipment, you can also consult network equipment manufacturers or customize proprietary wireless solutions to create an effective wireless access method tailored for you.

Summary: Through the above introduction, I believe everyone has a certain understanding of improving Wi-Fi performance. You can start with the configuration of the wireless router. After adjusting the internal configuration, look for possible external causes of interference. Improve Wi-Fi performance through proper deployment, placement and setup. And users can choose the above methods according to their actual situation and needs.
