Every 5 seconds: Wireless Network Utility [253]: Model -ioClassRef error

Hi I keep getting this in my console every 5 seconds, all day long.

In 2013 somebody reported a very similar problem, and he was told that "Wireless Network Utility" is a 3rd party product. Mine is called "Wireless-AC Network Utility" in the applications folder and it is from 2014. Seems to be an Apple component?

Can I just delete it? If not, what can I do. This is degrading performance somewhat.

Best regards

Thomas
