Hi @zrz4066, thanks for openning this issue!

Can you help me with more context? Could you please provide information such as OS, Version and how are you using the crate?

Its important to mention that theres no persisntance of data nor cache in the call to show.

Every invocation on show is idempotent, and will perform syscalls to pull data from the OS and parse it into crate structs.

That also happens to me in Windows 11. Maybe if you add a "is_up()" method (like default-net does) that will return true or false if the interface is plugged or not, will solve the problem.

Hi @Llorx!

Thanks for sharing insights, PRs are welcome in case you want to provide a suggestion on a fix!

I will mark this a windows and help wanted as I lack of access to Windows System ATM.

I would be glad, but the project where I use this crate is my first rust one, so I have a looooong way until I know how to do things properly. The borrow checker is a pain, being a noob xD

Maybe in a couple of weeks I can do so.
