Hello! I understand you're having trouble with your WiFi connection after the recent update. Let's work together to resolve this.

First, could you please confirm whether your WiFi network appears on your device? Additionally, does it provide any error messages when you attempt to connect?

Here are some general troubleshooting steps we can start with:

1. Restart Your Device: Sometimes simply restarting your iPhone can resolve connection issues.

2. Forget and Reconnect to WiFi:
- Go to Settings > Wi-Fi.
- Tap on the info icon (ℹ️) next to your WiFi network.
- Select Forget This Network.
- After that, reconnect by selecting the network from the list and entering the password.

3. Check for Other Devices: Are other devices able to connect to the same WiFi network? This helps us determine if it's a device issue or a network issue.

4. Network Settings Reset:
- If all else fails, you can reset your network settings:
- Go to Settings > General > Reset > Reset Network Settings.
- Keep in mind that this will also erase any saved WiFi passwords.

Let me know how these steps go or if you need guidance on any specific action!
