Here are the steps you should follow in troubleshooting your issue:

1. Verify the network name and password entered match what was set up in the router.
2. Check that wireless extenders or access points (like a Google WiFi setup) have been configured correctly.
3. Try resetting the router and reconfiguring the network.
4. Confirm that your laptop has the correct wireless driver installed and is current with the latest security updates.
5. Change the wireless setting on your laptop to use 2.4GHz or 5GHz.
6. If possible, try connecting a different device to the network to make sure the issue isn’t isolated to your laptop.
