Hello RichardMillin,
Welcome to the Microsoft Community.
We understand that you are faced with a situation where your laptop can successfully connect to other wireless networks, while your problematic wireless network is also available to other devices. Basically, the former fact indicates that the problem is unlikely to be on your laptop's side, and the latter situation may be caused by some settings of the blocked device, or the so-called banned list settings in the WLAN background setting page.
So, we recommend you first check the WLAN's setting page through entering a certain IP address in web browser and signing in a default admin account, which can be found on the back of the router (if there's no such information, you may need to contact the router's support service for some information).
After signing in successfully, besides from checking the block list, you have these options to consider:
- SSID Visibility: Ensure that the router is broadcasting its SSID (network name). Sometimes routers may be configured to hide their SSID, which could cause issues for certain devices when trying to connect.
- Channel and Band: Check if the router is set to a particular Wi-Fi channel that may not be supported by your Realtek RTL8822CE adapter. You could try switching to a different channel (especially between channels 1–11 for 2.4 GHz) or ensure the router is not set to use a DFS (Dynamic Frequency Selection) channel.
- Wi-Fi Security Type: The error message you received suggests that the issue might be related to connecting to a secure network. Make sure the Wi-Fi security settings (e.g., WPA2/WPA3) on the router are compatible with your laptop’s wireless card. You might want to try temporarily setting the router to WPA2-only mode as a test (if it's currently set to WPA3).
A quickest way is to reset the WLAN, and change another WLAN SSID, which is the same as setting up a new Wi-Fi for your laptop to try to connect to.
Additionally, we recommend you another direction to consider: The event logs indicate that your laptop is trying to connect to a secure network without a profile, which is unusual. If you’ve forgotten the network and tried reconnecting, there might be a corrupted network profile that’s causing issues. Follow these steps to clear any residual profiles and reconfigure the connection:
- Delete all saved network profiles:
- Open Command Prompt as Administrator and run: netsh wlan show profiles netsh wlan delete profile name="ProfileName"
- This will list all saved Wi-Fi profiles. For each profile related to your router, run:
- Recreate the network profile by connecting manually again. Be sure to enter the correct credentials.
Reset TCP/IP Stack:
It seems you've already run the typical network resets, but it's worth trying a deeper reset on the TCP/IP stack:
- Open Command Prompt as Administrator and run: netsh int ip reset resetlog.txt
- After this, restart your laptop to ensure changes take effect.
Power Settings and Adapter:
- Power Saving Features: Check if your wireless adapter’s power settings are causing it to be disabled during startup. In Device Manager, find your Realtek adapter under "Network adapters," right-click, and go to Properties > Power Management tab. Ensure that "Allow the computer to turn off this device to save power" is unchecked.
- Uninstall and Reinstall the Driver: Even though you've updated the driver, it may help to uninstall it and then reinstall it. In Device Manager:
- Right-click the Realtek adapter and choose Uninstall device.
- Click on the "detect hardware change" button on the top bar, to allow Windows to automatically reinstall the correct driver.
- You could also manually download the latest driver from the Realtek website (or your laptop manufacturer’s support page) to reinstall it.
Check for Interference and Signal Issues:
The RSSI: 255 in the log indicates that the laptop is not receiving a signal from the router, which suggests it can't detect the network. Try these:
- Move your laptop closer to the router and test the connection.
- Interference: Check if there are any other electronic devices (microwaves, cordless phones, etc.) near the router that could be causing interference on the 2.4 GHz band. Consider switching the router to 5 GHz if possible.
Advanced Network Reset:
As a last resort, you can perform a full network reset in Windows 11:
- Go to Settings > Network & Internet.
- Scroll down and click Advanced network settings.
- Under More settings, click Network reset.
- Click Reset now and confirm the action.
This will remove and reinstall all network adapters and reset network configurations to their defaults.
After performing these steps, check if the issue is resolved. If not, there could be a deeper hardware or software issue that may require additional support, or you may want to test the laptop on another router to rule out specific compatibility issues with your router.
