There are many possible reasons for disconnection, such as problems with the network itself, network card hardware problems, or system problems. You can confirm through other networking devices whether there is also the case of disconnection; if the network itself is not a problem (other devices can be connected normally), the problem is the computer itself:
1, update the network driver
Driver is often the crux of many problems. In the search box, enter Device Manager and open it, find the corresponding network card device, right-click and select Update Driver. You can either do this automatically or go to the official website and download the latest network drivers for your model.
2, Troubleshooting
Updating the driver does not work, we can use the system itself to provide the Troubleshooting function to seek a solution. The first thing you need to do is to search for a solution to the problem and then click on the corresponding item on the right side, choose to run the solution and follow the wizard's instructions to see if you can solve the wireless connection problem.
3. Network reset
If you can't solve the problem above, you can reset your network to solve it completely. Path: Start - Settings - Network and Internet - Status, find Network Reset in the list on the right and click on it, follow the prompts to complete the operation.
In addition, in the limited hardware conditions, want to make the existing network speed can be faster, you can refer to the following steps:
Step 1. Win + R key combination after typing gpedit.msc to enter the Group Policy Editor, in turn, into the "Computer Configuration - Windows Settings" After that, find the option "Policy-based Qos" on the right side.
Step 2. Right-click on "Policy-based Qos", select "Advanced QoS Settings", and in the Inbound TCP Traffic tab, check the box "Set inbound TCP throughput levels". In the Inbound TCP Traffic tab, check "Set inbound TCP throughput level" and select "Level 3" at the end.
Note: If you find that your system is bogged down and lagging when you are surfing the web after you change the settings, you can adjust the "Set Inbound TCP Throughput Levels" setting to "Level 2" to reduce the data processing pressure on your system hardware (for those with less than 4GB of RAM, you can adjust the setting to "Level 2"). (If memory is less than 4GB, it is recommended to use the default minimum throughput).
What are "advanced QoS settings"?
The advanced Quality of Service (QoS) settings allow you to manage bandwidth usage and the way your computer handles DSCP flags set by applications and services, rather than flags set by Group Policy. Advanced QoS settings can be applied only at the computer level, while QoS policies can be applied at both the computer level and the user level.
To change the throughput level, check the Specify inbound TCP throughput level check box and select a throughput level based on the table below. The throughput level can be equal to or less than the maximum value, depending on network conditions.
