Maui.NetworkMonitor

Repository

MAUI library for Android and iOS that reports real internet availability, not just “connected to a network”.

It watches native path changes, classifies Wi-Fi vs cellular, and uses HTTP probes (plus Android captive-portal capabilities) to detect:

  • Validated public internet
  • Captive portals (hotel / airport / guest Wi-Fi sign-in)
  • Offline and local-network-only states
  • Wi-Fi ↔ mobile transitions

Install

dotnet add package Plugin.Maui.NetworkMonitor

Target frameworks shipped: net8.0, net9.0, and net10.0, with net9.0/net10.0 Android and iOS packs.

Usage

using Maui.NetworkMonitor;

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder.UseMauiApp<App>();

        builder.Services.AddNetworkMonitor(options =>
        {
            options.EnableHttpProbe = true;
            options.EnableCaptivePortalDetection = true;
            options.ReprobeInterval = TimeSpan.FromSeconds(30);
        });

        return builder.Build();
    }
}

public sealed class ConnectivityViewModel
{
    public ConnectivityViewModel(INetworkMonitor monitor)
    {
        monitor.StatusChanged += (_, e) =>
        {
            if (e.Current.IsCaptivePortal)
            {
                // Prompt the user to sign in.
            }

            if (e.IsTransportTransition)
            {
                // e.g. Wi-Fi → Cellular
            }
        };
    }
}

Manual use without DI:

using var monitor = NetworkMonitor.Create();
monitor.Start();
var status = await monitor.RefreshAsync();

What NetworkStatus tells you

Property Meaning
HasInternet Public internet was validated
IsCaptivePortal Sign-in page is intercepting traffic
Reachability Offline, LocalNetworkOnly, CaptivePortal, Internet
PrimaryTransport WiFi, Cellular, Ethernet, …
IsExpensive / IsConstrained Metered / Low Data Mode
ActiveTransports All transports on the current path

NetworkChangeKind.TransportChanged is raised for Wi-Fi ↔ cellular handoffs.

How detection works

  1. Android — ConnectivityManager.NetworkCallback plus NET_CAPABILITY_VALIDATED and NET_CAPABILITY_CAPTIVE_PORTAL.
  2. iOS — NWPathMonitor for path status, Wi-Fi/cellular, expensive, and constrained flags.
  3. HTTP probes — known generate_204 / hotspot-detect endpoints. A 204 or expected success body is internet; a redirect, unexpected HTML, or TLS interception on a connected path is treated as a captive portal.

Probes use SocketsHttpHandler with redirects disabled so portal login pages are visible.

Permissions

The Android package declares:

  • INTERNET
  • ACCESS_NETWORK_STATE
  • ACCESS_WIFI_STATE

No extra iOS entitlements are required. Optional ATS exceptions for the HTTP probe hosts improve captive-portal accuracy if the OS blocks cleartext:

<key>NSAppTransportSecurity</key>
