Hello,
For your problem, here are a few possible solutions and suggestions for you to try:
Check and optimize router Settings: First, ensure that the router is placed in a location with good signal coverage to reduce interference with the signal from obstacles. Second, use Wi-Fi analysis tools to select a channel with less interference to improve the stability of the connection. Finally, check and update your router's firmware to the latest version to fix possible bugs or security vulnerabilities.
Check and update network drivers: Visit the official website of your computer manufacturer or network adapter manufacturer to download and install the latest network drivers. If the problem persists after the update, consider rolling back to the previous stable version to rule out driver incompatibility or corruption.
Using a Wired connection Test: In order to determine whether the problem is caused by a wireless connection, it is recommended to try connecting the computer directly to the router using an Ethernet cable. If the wired connection is stable, there may be a problem with the wireless adapter or wireless signal that needs further investigation.
Scan for malware: Do a thorough scan of your computer with reliable antivirus software to ensure that no malware is running in the background and interfering with your network connection. The malware may tie up network resources or modify system Settings, causing an unstable Wi-Fi connection.
