Troubleshooting Wi-Fi Connectivity Issues After Hardware Maintenance on Windows 11 Laptop

Experiencing Wi-Fi connectivity problems after hardware repairs can be frustrating, especially when relying on a stable internet connection for online classes or work. Recently, a user encountered such an issue following a routine repair involving replacing the keyboard and battery of their Windows 11 laptop. Here’s a comprehensive overview of the situation and some recommended troubleshooting steps.

Background:
The repair involved replacing the battery, which had become bloated, and fixing malfunctioning keys on the keyboard. Upon returning the device, the user observed two key issues:
– Wi-Fi disconnection
– System time offset by an hour

Initial Observations:
Despite the Wi-Fi disconnect, the laptop detected the router, indicating the hardware still recognized the network. Attempting to connect manually yielded a very weak signal even when in close proximity to the router. The user checked network settings, noticing that IP address and DNS server assignments were set to automatic, raising concerns about potential misconfigurations.

Potential Causes:
Various factors can contribute to such connectivity issues following hardware repairs:
– Network adapter driver conflicts or misconfiguration
– Incorrect network settings or IP/DNS configuration
– Hardware-related issues with the Wi-Fi card post-repair
– Time synchronization problems, possibly linked to system clock settings

Recommended Troubleshooting Steps:

1. Restart Network Components:
2. Restart your laptop and router to refresh network connections.

3. Ensure the Wi-Fi adapter is enabled via the network settings.

4. Verify Network Settings:

5. Open ‘Settings’ > ‘Network & Internet’ > ‘Wi-Fi’ > ‘Manage known networks.’
6. Select your network and choose ‘Forget.’

7. Reconnect by selecting the network and entering the password anew.

8. Check and Reset IP and DNS Settings:

9. Open Command Prompt as administrator.
10. Run the following commands to reset TCP/IP and renew your IP address:
    netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew

11. Confirm that DNS is set to automatic, or specify a reliable DNS server such as Google’s (8.8.8.8).

12. Update or Reinstall Network Drivers:

13. Visit the device manufacturer’s website to download the latest drivers compatible with your model.
14. Alternatively, in Device Manager:
    • Locate the network adapter.
    • Right-click and select ‘Update driver.’
    • Choose ‘Search automatically
