Reason one: It's too far away from the router.
Generally speaking, the space that a router can cover is limited, about 60m2. Therefore, when we use the wireless network to surf the Internet, we can be as close to the signal source as possible.
Conditional friends can put more routers according to the structural characteristics of their families. For a multi-storey house, put a router on each floor, which can prevent the problem of poor network signal and slow network speed because it is too far away from the router.
Reason 2: The router has not been turned off for a long time.
I believe many people have not noticed this, but at home, we basically don't turn off the router. But routers, like light cats and mobile phones, actually produce a lot of caches. The more caches are piled up, the slower the network speed will be. In the long run, our wireless network will be as slow as a tortoise.
In this case, the solution is also very simple, that is, turn off the router regularly, so that the router will automatically clean up the garbage and the network speed will return to normal.
Reason three: signal interference.
There are more and more wireless devices around us. Bluetooth devices, microwave ovens, cleaning machines, dryers, etc. all work in the 2.4GHz public frequency band, which is also the "real killer" that interferes with your wireless network. Many home routers are still 2.4G single-frequency signals, and the 2.4G frequency band provides multiple overlapping channels, so there will be strong mutual interference when there are multiple routers nearby.
Now, the new router can provide 2.4GHz and 5GHz bands. In the case of high broadband requirement and close to WiFi signal, if you choose 5GHz band signal, the network speed will be much faster.
Methods to improve the speed of wifi
The firmware of the router will also affect the speed of WiFi, but it is not as convenient as downloading software when upgrading the firmware of the router. It needs to be downloaded from official website, a router manufacturer, and then uploaded through the router's web interface. Although these firmware can't directly increase the signal range, they can improve the performance of the router.
If you have multiple routers, you can enjoy the bridging of wireless routers through the trunking mode in the device. This will not only expand the wireless wifi signal network, but also improve the wifi network speed, making your wifi coverage wider and more suitable for high-speed broadband.
