AttributeError: 'managed' object has no attribute 'wmIface'

[M. Arif Hakimi]

The error message you're seeing, AttributeError: 'managed' object has no attribute 'wmIface', suggests that there's an issue with the Mininet-WiFi library version you're using.

1. Check your Mininet-WiFi Version: The script you're using might be written for a different version of Mininet-WiFi. Confirm the compatibility of your script with the version of Mininet-WiFi you have installed.

2. Review the Code: Look for where wmIface is supposed to be defined. It's possible there's a change in the library or a mistake in your script. Make sure you are setting up everything correctly, particularly when you configure the wireless nodes.
