Reset generale consigliato, solo schede fisiche attive:
:>>
Get-NetAdapter -Physical |
Where-Object { $_.Status -eq "Up" } |
Restart-NetAdapter -Confirm:$false

>>:

Resettare proprio tutte le schede abilitate, incluse virtuali/VPN/Tailscale:
:>>
Get-NetAdapter |
Where-Object { $_.Status -ne "Disabled" } |
Restart-NetAdapter -Confirm:$false

<<:
