How to Verify Network Connectivity in .NET MAUI | Community Feed

Knowing a device’s connectivity state lets you make smarter decisions and give users clearer feedback. Leomaris Reyes shows how .NET MAUI’s IConnectivity API exposes rich network details with very little code.

What you’ll learn

Platform setup — adding the ACCESS_NETWORK_STATE permission on Android (three ways), with no configuration needed on iOS/Mac Catalyst or Windows
Inspecting network scope — interpreting the NetworkAccess values: Internet, Local, None, Unknown, and ConstrainedInternet (captive portals)
Detecting connection profiles — reading ConnectionProfiles to tell whether WiFi, Cellular, Bluetooth, or Ethernet is active
Reacting to changes — subscribing to the ConnectivityChanged event to respond in real time
An important caveat — why a network connection doesn’t guarantee real internet access
