The image shows that your WiFi adapter, "Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC", is listed under "Network adapters". This means Windows detects the hardware and its driver is likely installed. Since it's listed but your WiFi has disappeared, here are the next steps: Step 1: Check the status of the Realtek WiFi adapter in Device Manager. • Right-click on "Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC". • Check if there is an option to "Enable device". If so, click it. • If it's already enabled, select "Properties". Look under the "General" tab for "Device status". It should say "This device is working properly." If there's an error message, note it down. Step 2: Check Network Connections. • Go to the Windows search bar and type "Network Status" or "Network and Internet settings". • Click on "Change adapter options" (or "Change adapter settings"). • In the "Network Connections" window, find your "Wi-Fi" adapter (it should be labeled with the Realtek name or just "Wi-Fi"). • Right-click on it. If it says "Enable", click it. If it says "Disable", it means it's already enabled. Step 3: Restart the WLAN AutoConfig service. • Press Windows key + R to open the Run dialog. • Type services.msc and press Enter. • In the Services window, scroll down and find "WLAN AutoConfig". • Right-click on "WLAN AutoConfig" and select "Restart". If it's not running, select "Start". Ensure its "Startup type" is set to "Automatic". Step 4: Check for a physical WiFi switch or function key. • Double-check your laptop for a physical switch that turns WiFi on/off. • Look for a function key combination (e.g., Fn + F2, Fn + F5, or a key with an antenna icon) that might toggle WiFi or airplane mode. Step 5: Update or reinstall the driver. • If the above steps don't resolve the issue, go back to Device Manager. • Right-click on "Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC". • Select "Update driver" and choose "Search automatically for updated driver software". • If that doesn't work, right-click again and select "Uninstall device". Do not check the box to delete the driver software. • After uninstalling, restart your laptop. Windows should automatically reinstall the driver. If not, go back to Device Manager, click "Action" -> "Scan for hardware changes".
