My HP laptop suddenly refuses to connect to Wi‑Fi. I already restarted it, reinstalled the network driver, and tried the version from HP's official website, but nothing changed. The problem started after uninstalling the Realtek RTL8822CE 802.11ac PCIe Adapter while trying to set up Miracast. Device Manager now shows warning icons beside the Realtek Wi‑Fi adapter, Bluetooth Device (Personal Area Network), and Microsoft Kernel Debug Network Adapter. Windows Help also says the Ethernet network adapter is disabled. I downloaded an HP driver installer on another computer and copied it over, but running the HP.exe file did not fix anything. What is the correct way to restore the Wi‑Fi and Bluetooth drivers?

Check whether the adapter is disabled rather than only missing its driver. In Device Manager, right-click the Realtek RTL8822CE entry and choose Enable device if that option appears. Also check Settings or Control Panel under Network Connections and enable the Wi‑Fi adapter. The Microsoft Kernel Debug Network Adapter usually is not the adapter you need for normal internet access, so focus on restoring the Realtek device first.
If you can access the router with a network cable, use that temporarily to download the correct driver. If your laptop has no Ethernet port or you cannot connect that way, USB tethering from a phone is another option. Once Windows is online, Windows Update or HP Support Assistant may be able to reinstall both the Wi‑Fi and Bluetooth components automatically.
The RTL8822CE chip handles both Wi‑Fi and Bluetooth, so the warning icons may be related. Download the exact driver package for your HP laptop model from HP’s support page using another computer, then transfer it with a USB drive. If the installer does nothing, extract the package first and install it manually through Device Manager: right-click the Realtek adapter, choose Update driver, select Browse my computer, point it to the extracted folder, and include subfolders. Restart afterward.
I tried copying over the HP package and running the executable, but I’ll try extracting it and selecting the driver folder manually through Device Manager.
