How It Works:
- Get-NetAdapter returns every network adapter recognized by the system, alongside its current link speed.
- LinkSpeed shows the negotiated connection speed in a readable format - already converted to Mbps/Gbps rather than a raw number.
- An adapter showing 0 bps (like Wi-Fi here) typically means it's disconnected or inactive - the machine is using a different adapter (Ethernet) for its actual connection.
