Run `Set-NetIPInterface -InterfaceAlias "Ethernet" -Dhcp Enabled` as admin to put the adapter back on DHCP.

01Command

Command
$ Set-NetIPInterface -InterfaceAlias "Ethernet" -Dhcp Enabled

02What it does

If a static IP experiment left the adapter misconfigured, flipping the interface's DHCP flag back to Enabled makes Windows lease an address, gateway, and DNS from the router again. The change applies immediately; if the adapter doesn't reconnect, run ipconfig /renew afterwards. Verify the result with Get-NetIPAddress -AddressFamily IPv4.
