Internet Reachability Verifier verifies internet connectivity. It offers many captive portal detection methods and supports multiple platforms. Minimal setup, no native code, includes C# source.

Internet Reachability Verifier helps you be sure that the internet can be truly reached. Application.internetReachability isn't enough to know that. This is first asset of its kind (check online connectivity). It's also very small: there's only a few files, you only need a single MonoBehaviour - no nonsense of hundreds of extra files! It's actively supported.

• Automatically monitors and verifies internet reachability, implemented using a light-weight coroutine.

• If internet connectivity stops working middle of your own networking and you get error codes from some networking library, you can ask for reverification of the internet reachability (this asset will not actively monitor loss of effective networking, as that would use up user's mobile data quota unnecessarily).

• 14 different captive portal detection methods: Google204, Google204HTTPS, GoogleBlank, GoogleBlankHTTPS, MicrosoftNCSI, MicrosoftNCSI_IPV6, Apple, Apple2, AppleHTTPS, Ubuntu, UbuntuHTTPS, MicrosoftConnectTest, MicrosoftConnectTest_IPV6, Custom.

• Default setting is to automatically pick a suitable ("native") captive portal detection method by platform.

• Optional delegate for matching returned data for using custom method.

• Optionally append cache buster to url when using the custom method.

• Detailed internet access status property (Offline, PendingVerification, Error, Mismatch, NetVerified).

• Easy callback for listening to changes in the internet access status property (optional).
