Check router guest support in its app or settings and replace the default admin password.
Update firmware and select WPA3 Personal or WPA2 Personal where supported; avoid WEP.
Enable guest Wi-Fi with a separate name and strong password.
If available, restrict guest access to the internal network; check the model's isolation options.
