• 📶 Weak signal or interferenceThe network is visible, but the connection keeps dropping. Check the distance to the router and the presence of obstacles (walls, metal structures).
• 🔄 IP address conflict: The device receives an IP address, but there is no internet access. Settings → Wi-Fi → (i) next to the network see section IPv4 address.
• 🛠️ Incompatible router settings: For example, included WPA3 on older models iPhone or incorrect region in wireless network settings.

"Incorrect Passcode" Error: What to Do If Your iPhone Doesn't Accept the Correct Password

1. Delete the network and reconnect:

   Go to Settings → Wi-Fi, tap on the network name, then select "Delete this network" After that, try connecting again by entering the password manually (do not use autofill!).

2. Check case and hidden characters:

   Passwords are case sensitive! Make sure that Caps Lock disabled. If the password is copied from a message or file, it may contain invisible spaces or line breaks. Please enter the password manually.

3. Change the encryption type on your router:

   Some iPhone (especially older models) don't work well with WPA3Go to your router settings (usually at 192.168.0.1 or 192.168.1.1) and in the section Wireless Security select WPA2-PSK (AES).

If nothing helps, try temporarily disable the password on the router (set the security type Open), connect iPhone, and then restore the previous settings. This will help determine whether the problem is with the password or something else.

⚠️ Attention: If after changing the password on the router iPhone It stopped connecting, but other devices work fine - the problem is definitely in the settings. iOSGo to . section on resetting network settings.

   In the same menu, select "Configure IP» → «Manually" Enter:

   • IP address: 192.168.1.X (where X is a number from 10 to 254 not occupied by other devices)
   • Subnet mask: 255.255.255.0
