network disappearance

The network disappearance tag on WindowsForum.com covers issues where network adapters vanish from Windows after a reboot. In one reported case, a Windows 11 system upgraded from Windows 10 loses both wired and wireless network cards—including USB adapters—after the first successful boot. The network card is missing from Device Manager and ipconfig shows no adapters. This problem persists across different hardware and occurs on every reboot after the initial installation. Discussions focus on troubleshooting steps such as checking driver integrity, power management settings, and Windows update history to identify the root cause of the disappearing network hardware.
