Hi Jeanette, I understand how frustrating this can be. When Wi-Fi keeps disconnecting and only a reboot brings it back, it usually points to a network stack or driver issue. Here are a few steps you can try:
Reset the network stack. Open Command Prompt as administrator and run these commands one by one: netsh winsock reset netsh int ip reset ipconfig /release ipconfig /renew ipconfig /flushdns Restart your PC after running them.
Disable power saving for your Wi-Fi adapter. In Device Manager, open your Wi-Fi adapter properties, go to Power Management, and uncheck “Allow the computer to turn off this device to save power.”
Reinstall the Wi-Fi driver. Uninstall it from Device Manager, check the box to delete the driver, restart, and then install the latest version from the manufacturer’s website.
Make sure the WLAN AutoConfig service is running and set to Automatic. You can check this in services.msc.
If none of these steps work, creating a new user profile or doing a repair/reset install of Windows 11 can help fix deeper system issues.
Let me know if you want me to guide you through any of these steps. If this answer helps, marking it as helpful or accepted can make it easier for others to find the solution too. Best, Carl
