About privacy and security warnings
If your Apple device shows a privacy warning or weak-security warning about a Wi-Fi network, that network could expose information about your device. Apple recommends connecting to Wi-Fi networks that meet or exceed the security standards in this article.
Weak security settings to avoid on your router
Don't create or join networks that use older, deprecated security protocols. These are no longer secure, they reduce network reliability and performance, and they cause your device to show a security warning:
- WPA/WPA2 mixed modes
- WPA Personal
- WEP, including WEP Open, WEP Shared, WEP Transitional Security Network, or Dynamic WEP (WEP with 802.1X)
- TKIP, including any security setting with TKIP in the name
Settings that turn off security, such as None, Open, or Unsecured, are also strongly discouraged. Turning off security disables authentication and encryption and allows anyone to join your network, access its shared resources (including printers, computers, and smart devices), use your internet connection, and monitor the websites you visit and other data transmitted over your network or internet connection. This is a risk even if security is turned off temporarily or for a guest network.
If it is your own router, you can consider a newer router. Normally, a router older than 5 years is replaced, with a router that meets the latest security requirements. But that's your own choice.
Is it a router from the ISP, ask your ISP.
