How to resolve persistent Wi-Fi connectivity issues on a Windows 10 laptop with a Realtek 8822BE wireless card?


I have a Windows 10 laptop with a Realtek 8822BE wireless card that frequently experiences extremely slow and unstable Wi-Fi connection. The problem occurs randomly and affects all web browsers and applications that use the internet. I get various error messages such as ERR_CONNECTION_RESET, ERR_CONNECTION_CLOSED, ERR_NETWORK_CHANGED, and Socket Error. The problem persists even after reinstalling the driver, resetting the computer, disabling the firewall and antivirus, and changing the driver's settings. The troubleshooters do not detect any issues with the drivers, connection, or anything else. The laptop claims that it has a good connection to the router, but the network utilization is very low. The only temporary solution I have found is to run some commands in the command prompt, but they do not always work and the problem comes back soon. I have contacted Microsoft and Asus support, but they were not helpful. No other device in my network has this problem. What could be the cause of this problem and how can I fix it?
