What should I do if the wireless router receives the wifi signal badly?

1. Changing the signal channel When using a wireless router, the router usually sets a default channel, which may be the most congested. So you can change the channel in the router settings, or you can achieve the same effect by using the free tool inSSIDer. Don't be confused by the seemingly complicated charts of the software, just change to a less crowded channel. 2. Updating the firmware of routers is often ignored by home users, because commercial routers often have the function of firmware update notification, while home products do not. In fact, the new version of firmware is often improved in signal and performance. You can try to use the "Check Version Update" function in the router setting interface or go to official website to download it yourself. 3. Updating the wireless network card driver In addition to updating the router firmware in time, it is equally important to update the computer's network card firmware, which will also improve the computer's WIFI signal search capability in some cases. Most laptops have built-in wireless network cards. Just go to the control panel to find the name of the network card, and then go to official website to download the latest driver installation. 4. Change the location of the router Usually, we will put the wireless router closest to the broadband modem, but in fact, the best location is in the middle of the whole house. Of course, it depends on the size of your house. If it's just a one-bedroom apartment, it may not matter much where the wireless router is placed. If it is a large duplex room with three rooms and two halls, then the wireless router should be placed in the center of the house as far as possible to bring good wireless signals to the second floor space. The whole cost is actually very low. If you are far away from width modem, you can buy a long Ethernet CAT 5 cable. 5. Install DD-WRT open source firmware DD-WRT is a well-known router open source firmware, similar to the custom firmware in the field of smart phones, which can usually maximize the performance of wireless routers and add more functions. Of course, not every router supports DD-WRT firmware. Please visit DD-WRT's website for details. In addition, because the firmware is in the form of open source customization, the router lost its official warranty service after installation. Therefore, it is recommended that you choose DD-WRT firmware after the warranty period to improve performance. 6. Set up a cheap wireless router as an access point or relay. If the above software methods have limited effect, then we should start to consider the hardware. First, the lowest cost 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, specify the same SSID and secure channel for it, and turn off the automatic IP allocation function of DHCP. In addition, the wireless relay function can also be realized by bridging, but the setting is relatively complicated, so it is recommended to use the same brand router to be more successful. If these network configurations are a headache, you can also choose a more expensive private access point, such as dual-band Cisco WAP6 10N. 7. Upgrade the antenna of the wireless router Although more and more wireless routers are designed with built-in antennas, some models still have external antennas, which can usually be upgraded. 8. Buying a dedicated wireless network repeater can effectively extend the coverage distance of WI-FI signals, but it may require complicated setup and is relatively expensive. A good wireless repeater may cost about $200 (about RMB 1227). 9. Buy a new wireless router If your wireless router service has been used for a long time, it is a good choice to replace it with a product that supports the latest standards. At present, most of the new wireless routers support 802. 1 1n and use the 5 GHz frequency band, which greatly improves the performance and signal coverage. Relatively speaking, the 2.4GHz band covers a larger area, while the 5GHz band has better performance in a relatively small area. At present, some high-end models support dual frequency, which can achieve a more comprehensive experience. In addition, it should be noted that if you choose a new 802. 1 1n router, you'd better ensure that the corresponding internet devices also support this standard to achieve better connection effect.
