How To Fix the Insecure Network Warning on iPhone
Check the Wi-Fi Security Type
iOS shows the insecure network message when a Wi-Fi network uses outdated encryption or no password protection.
Time needed: 3 minutes
- Open Settings on your iPhone.
- Tap WLAN.
- Tap the information (circled “i”) icon next to the network.
- Check the Unsecure Network warning for details.
Networks using WEP, WPA, or open security can trigger the warning.
Switch the Router to WPA2 or WPA3
Modern routers support stronger encryption standards. Using WPA2 or WPA3 removes the insecure network alert.
Sign in to your router settings and change the wireless security mode to WPA2-Personal or WPA3-Personal.
If both options exist, WPA3 offers the strongest protection. WPA2 offers broader compatibility with older devices.
Enable a Wi-Fi Password
Open networks without passwords always show security warnings on iOS.
Add a strong Wi-Fi password in your router settings and reconnect your iPhone.
Forget and Reconnect to the Network
Cached network settings can sometimes cause incorrect warnings.
Go to Settings > Wi-Fi, tap the network, choose Forget This Network, then reconnect.
Disable Private Relay or VPN Temporarily
Some VPNs and network filters interfere with Wi-Fi security detection.
Turn off VPN or iCloud Private Relay briefly to see if the warning disappears.
Update Router Firmware
Outdated router firmware may lack modern encryption support.
Install the latest firmware from the router manufacturer and restart the router.
