Why is the wifi signal full but the network speed is slow?

Causes: 1. Signal interference; such as distance or magnetic field, etc. If an induction cooker or microwave oven is placed next to the router, even if the WiFi signal is full, it will lead to a poor Internet experience. Of course, there are more Sometimes the signal is not full. 2. There are reasons for the receiving device itself, such as the current wireless network card is damaged or aging, etc.; 3. The quality of the router is not good, or the router configuration is too low, such as low memory, which may cause congestion problems. Once there are too many connected devices; 4. , Internet use; 5. Speed ​​limit; 6. Signal congestion.

Sometimes when we use WiFi, we often encounter situations where the WiFi signal is full, but the network speed is very poor or the Internet cannot be connected at all. So what is going on? I believe many people will encounter this problem, so today, U Hero will share with you why the WiFi signal is full but there is no good Internet experience.

Signal interference

WiFi signals are easily interfered by factors such as distance or magnetic field. If an induction cooker or microwave oven is placed next to the router, the WiFi signal will be full even if it is full. The situation will also lead to a poor Internet experience. Of course, more often the signal will not be full.

Receiving equipment

The WiFi Internet experience is poor, and there are also reasons for the receiving equipment itself, such as the current wireless network card is damaged or aging, etc., or when using a mobile phone At this time, my hands covered the external antenna strap, which is also one of the reasons for poor network performance.

Router or network

The quality of the router is not good, or the router configuration is too low, such as low memory, then congestion problems may occur. Once there are many connected devices Even if the signal is full, the data cannot be processed, causing network delays or freezes. The other problem is the network itself. Of course, you have to consult the local operator to know the specific reasons.

Many people now set WiFi passwords relatively simply, and simple WiFi passwords are easily cracked by brute force. There are various cracks on the Internet. It is a WiFi password tool, so once the password is cracked, your WiFi may be used by N number of people, and it would be strange if it is not stuck. If you don’t want to be exploited, the easiest way is to set up a MAC address whitelist, or hide the broadcast SSID. The MAC whitelist only allows devices on the list to access the Internet, while hiding the SSID actually hides the name of the WiFi from others. device is displayed.

speed limit

If you connect to a public WiFi and the signal is full but there are problems with high network latency and poor network speed, this kind of problem Generally, the speed is limited. In order to facilitate everyone's use, public WiFi will allocate a certain bandwidth to each device connected to WiFi to ensure normal use by everyone.

Signal congestion

If there are multiple WiFi signal sources near the router you are using, then these wireless signals will interfere with each other, especially The more the same channels, the stronger the interference. Signal interference will not affect the signal quality, but it will have a greater impact on the network speed. Therefore, many routers now have the function of automatically searching and setting channels. We can also do it manually. Settings, the channel number in my country is 1 to 13. For example, after detecting the channel, the surrounding WiFi channels are all 5, then we cannot set 5, but can change it to 6 or other channels. The less repeated numbers, the smaller the degree of signal interference.
