Description

Not sure if this bug belongs here. Don’t think it is a regression.

On Android 10 and Android 11, when connecting to a WIFI network that doesn’t have internet access, and the connection is performed through the OS WIFI settings, the netInfo object correctly shows the type as wifi, and the network details.

When connecting to the same WIFI network, and the connection is performed through the WifiManager.connectToProtectedSSID function from the react-native-wifi-reborn library (and the connection succeeds), the type in the netInfo object is always none and the connection details are empty.

Devices reflect being connected to the WIFI network, both on the control panel and the WIFI settings.

Not sure where this bug belongs.

• Experiencing this on several Android 10 and Android 11 devices.
• Having the same behavior with the useNetInfo hook, as well as when adding listeners manually.

Reproducible Demo

import React, { useEffect } from 'react';
import { useNetInfo } from '@react-native-community/netinfo';
import WifiManager from 'react-native-wifi-reborn';

const SomeComponent = () => {
    const netInfo = useNetInfo();

    ...

    useEffect(() => {
        console.log(netInfo);
        // netInfo object never reflects being connected to the wifi that has no internet access.
        // Instead, it shows:
        // {
        //     details: {}
        //     isConnected: false
        //     isInternetReachable: false
        //     isWifiEnabled: true
        //     type: "none"
        // }
    }, [netInfo]);
    
    useEffect(() => {
        WifiManager.connectToProtectedSSID('network-without-internet-access', '', false);
    }, []);

    ...

}

Please let me know if there’s more information I can provide.

Thanks!

@pherrera91, when connecting to a new WiFi network, make sure to wait a little so all changes can be fetched correctly. You might also be getting a cached network information. If you just want to fetch the WiFi status and avoid any caching, you may call NetInfo.fetch("wifi").

Did a little bit more digging into the issue.

This is not true.

When connecting to the same WIFI network, and the connection is performed through the WifiManager.connectToProtectedSSID function from the react-native-wifi-reborn library (and the connection succeeds), the type in the netInfo object is always none and the connection details are empty.

It seems the issue is not that none is returned. none being returned is okay, because that’s the state prior to being connected to a network. The problem is that the library is not detecting the connection to the new wifi network that has no internet, and no new data is returned.

I did some debugging and I ended up finding out that onAvailable (inside ConnectivityManager.NetworkCallback -> NetworkCallbackConnectivityReceiver.java) is never called for the network I’m connecting to.

I’m still looking at it, to see if I find something else.
