What to do if the Wi-Fi signal is poor?

Solution to poor Wi-Fi signal: 1. Change the channel in the WIFI settings in the router's background management page and switch to a less crowded channel; 2. Enter the control panel to find the name of the network adapter, and then Go to the official website to download the latest driver and install it; 3. Adjust the router placement; 4. Use a router as an AP signal relay.

Solution to poor wi-fi signal:

1. Change the signal channel

When using a wireless router, the router usually defaults to a channel, which may be the most congested one. Therefore, you can change the channel in the WIFI settings in the router's background management page and switch to a less crowded channel.

2. Update router firmware

Updating router firmware is often easily overlooked. In fact, new versions of firmware often improve signals, performance, etc., so you can try it yourself Go to the official website to download, and then import the router in the "Upgrade and Restart" function in the settings interface.

3. Update the wireless network card driver

In addition to updating the router firmware in a timely manner, updating the computer's network card firmware is equally important. In some cases, it will also improve the computer's WIFI signal search capability. Most laptops have built-in wireless network cards. Just enter the control panel to find the name of the network adapter, and then go to the official website to download the latest driver and install it.

4. Adjust the router placement

Normally, we will place the wireless router closest to the broadband modem (cat), but in fact, the best location is the house centre position. Of course, this depends on the size of your house. If it is only a one-bedroom apartment, it will not make much difference where the signal is placed; but if it is a large duplex with three bedrooms and two living rooms, then you should try to install the wireless router Place it on the stairs to bring good wireless signals to the second floor space.

5. Install open source firmware

Router open source firmware (such as DD-WRT) can usually maximize the performance of wireless routers and add more functions. Of course, not every router supports DD-WRT firmware. For specific information, you can log on to the DD-WRT website to check. In addition, since the firmware is in the form of open source customization, the router loses its official warranty service after installation. Therefore, it is recommended that you choose DD-WRT firmware after the warranty period to improve performance.

6. Use a router as an AP (switch) to relay signals

If the above software methods have limited effect, then you need to start thinking about hardware. First of all, the cheapest way is to add an access point (AP). Just set the second wireless router to AP mode and connect to the main router through the LAN port. You need to manually set the IP address and gateway of the second router, assign it the same SSID and secure channel, and turn off DHCP automatic IP assignment. In addition, the wireless relay function can also be implemented through bridge mode, but the setting is relatively complicated. It is recommended to use a router of the same brand to make it easier to succeed.

7. Upgrade the antenna of the wireless router

Although more and more wireless routers use built-in antenna designs, there are still some models that have external antennas, and they can usually be upgrade. After upgrading, the signal strength can be enhanced by at least 2dBi to 15dBi.

8. Use a dedicated repeater

A dedicated repeater can effectively extend the coverage distance of the WI-FI signal, and can continue the wireless network in places where the wireless signal is weak or even disappears, solving the problem The problem of signal blind spots allows wireless coverage to every corner you require. It is compatible with a variety of wireless terminals such as smartphones and tablets. It is now produced by manufacturers such as tplink, totolink, and Ecoliv on the market, and the price is only about 100 yuan.

9. Purchase the latest AC dual-band router

If your wireless router service has been used for a long time, it may not be a bad choice to replace it with a product that supports the latest standards. . Currently, AC dual-band routers support 802.11ac, because most routers now support the 2.4G frequency band, and many household appliances are also in the 2.4G frequency band, such as microwave ovens and other people's routers. Therefore, this frequency band is very congested, and no matter how fast the network is, it cannot run. 5G is like a newly built highway. There are fewer people using it and therefore fewer cars, so the speed can be very fast.
