Hello,
I set a static IP address for my NIC and connected my PC to another PC via a switch, but when I disconnected the network and removed the static IP address, my network connection icon show connected. My PC checking the network when Linux is booting and take some time.
Any idea?

Thank you.

It would help more, if you would tell the DE you are using.
