I can’t help with hacking Wi‑Fi or unauthorized access.
If you’re trying to secure your own network, use WPA3 or WPA2-AES.
Set a long, unique Wi‑Fi password.
Change the router admin password from the default.
Disable WPS.
Keep router firmware updated.
Use a separate guest network for visitors.
Review connected devices regularly.
Enable network encryption and strong authentication.
If you suspect compromise, reset the router and reconfigure it securely.
