Hello everyone. I’m having strange issue with wifi (intel 8265 iwlwifi) on my HP x2 1012 g2 with Fedora 43 kernel 6.18.8-200. At work I use an usb to ethernet adapter (cdc_ether module) in my notebook but at home I’m on wifi but Network Manager continously activate and deactivate cabled connection even if the adapter is not inserted and that drops down and up my wifi connection that, even if it remains connected to the router, interrupts the download and creates browsing problems. Then as a workaround I’ve blacklisted the “cdc_ether” module in /etc/modprobe.d/ and all gone well with my wifi. But the stranger thing happened when I came back to work. I was convinced that I need to remove the cdc_ether module from blacklisted and instead, by inserting the adapter, the module loaded normally. How is this possible?
Thank you
Module blacklisting does not fully prevent it from loading:

As an alternative, consider disabling autoconnect for the wired connection.

Thank you Vlad. I read what you suggested but, at the end, just blacklisting “cdc_ether” module have solved my issue and now, when I’m on wifi NM no longer tries to enable Ethernet.
