Hi,
First, is it just your ASUS laptop that is not connecting to your wireless network? Please do try these troubleshooting steps that may help in solving the issue.
- Start by uninstalling/reinstalling the wireless adapter.
- Go to Device Manager and uninstall the wireless adapter.
- Reboot your laptop and it should reinstall the driver automatically upon reboot.
- If it will not reinstall, download and install the latest wifi driver from Asus support site.
- Once installed do try connecting to your wireless network again.
- Also please do try these troubleshooting steps.

- If all these will not work do try to uninstall the antivirus installed in your laptop then try it again.
- Your last resort would be to reinstall Windows itself if all these will not work.
If its not just your Asus laptop that won't connect to the network I would suggest contacting your ISP first.
