Hi! Based on what you’ve tried, here’s how I’d approach this:
- Press Win + R, type devmgmt.msc, and check Device Manager > Network adapters.
- If you only see Realtek 8811CU (USB type) and not Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC, that suggests the system isn’t detecting your built-in WiFi card.
- If the 8821CE is missing even after uninstall/reinstall, the hardware might not be initializing.
- In Device Manager, click View > Show hidden devices.
- See if Realtek 8821CE shows as “grayed out” or with a yellow triangle.
- If it does, right-click > Enable (if available) or note the error code.
If it doesn't show, it might not be initialized, some laptops have a button to disable the WiFi/Bluetooth adapter, check yours.
