In Windows, a home Wi‑Fi network can be set to Private network, but Windows 11 sets new networks to Public by default, and Public network is the recommended setting in most cases. If the Private network option is not available or will not stay selected, try these checks:
- Open Settings > Network & internet.
- Select Wi‑Fi.
- Select the Wi‑Fi network currently connected.
- Under Network profile type, select Private network.
If the network details are hard to find, go to Network & internet settings and select Properties next to the connected network.
If the network keeps behaving like a public network after restart, one reported cause is third-party security software. In a similar case, Norton 360 Wi‑Fi security/VPN settings caused the network to be recognized as public. Resetting those settings and enabling the VPN resolved it for that scenario.
If the issue is specifically about Wi‑Fi security warnings such as “Wi‑Fi network not secure”, that is different from the public/private profile. That warning means the router may be using older security standards such as WEP or TKIP. In that case:
- Update the router security to a newer standard such as WPA3.
- If the router is old, consider replacing it with one that supports newer security standards.
- Make sure the router firmware is up to date.
- Change the router’s default admin password if it is still using the default.
