Basic Checkpoints

Before you delve into the advanced troubleshooting ways to fix WiFi connected but no internet access issues, we recommend you to check some key points mentioned underneath:

Only One Device Can’t Connect to WiFi?

Is it your laptop that is connected to WiFi but showing no internet error? Try connecting other devices to the internet as well and see if they are working properly. Grab your smartphone or another computer and connect it to your WiFi network. If the internet is properly working on that device, it means the issue lies with your laptop.

But if you are seeing connected to WiFi but no internet access error on your smartphone and other devices as well, then you have to apply some advanced troubleshooting hacks to fix the issue.

Fix: Connected to WiFi But No Internet Access

1. Check Your Router and Modem

Oh no! WiFi connected but no internet – what to do? Relax! The internet may not be working because of the technical issues with your router. Also, any issue with the WiFi adapter’s driver may also result in no internet access error.

So, reboot your home WiFi router as well as the modem once and try connecting to the internet again.

2. Set up Your WiFi Extender Correctly

Incomplete or partial Netgear WiFi extender setup is another reason why you are facing ‘can connect to WiFi but no internet’ error. Perhaps there is slow internet connection, improper extender placement, or incorrect login credentials – all such issues lead you to the partial extender setup. Thus you see your device connected to WiFi but no internet.

So, make sure that you install and configure your wireless range extender properly. You can also take our experts’ help while setting up your extender.

3. Turn Off Your Antivirus

Sometimes, antivirus programs may be a culprit behind no internet access issue on your device. Try to temporarily turn off antivirus and see whether you have internet access. In the event that the ‘connected to WiFi but no internet connection’ error is still there even after disabling antivirus programs, move to the next troubleshooting hack.

4. Check Your Extender’s Placement

On the off chance if your WiFi connection is not working, the wireless interference can be the culprit. Maybe your extender is placed near electrical gadgets, metal objects, or reflexive surfaces, e.g. microwaves, refrigerators, Bluetooth speakers, cordless phones, mirrors, glasses, aluminum studs, metal doors, electronic garage openers, etc.

Such devices interfere with the WiFi signals coming from your extender and leave you with a dropping internet connection. Therefore, make sure to keep your range extender far away from such devices.

5. Update Your Extender’s Firmware

If nothing resolves the connected to WiFi but no internet connection issue for you, consider updating your extender’s firmware. Outdated firmware versions cause your internet connection to drop. So, make sure that your extender is running on the latest firmware version. If not, update your WiFi extender firmware via the Netgear genie setup page.

So, these were some of the proven hacks to get rid of the ‘connected to WiFi but no internet’ issue. If you are still struggling with the same issue, don’t hesitate to contact our highly-experienced technicians.

android how to check wifi is connected but no internet connection

NetworInfo.isAvailable and NetworkInfo.isConnected only indicate whether network connectivity is possible or existed, they can’t indicate whether the connected situation has access to the public internet, long story short, they can’t tell us the device is online indeed.

To check whether a device is online, try the following methods:

@TargetApi(Build.VERSION_CODES.M) public static boolean isNetworkOnline1(Context context) < boolean isOnline = false; try < ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkCapabilities capabilities = manager.getNetworkCapabilities(manager.getActiveNetwork()); // need ACCESS_NETWORK_STATE permission isOnline = capabilities != null && capabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_VALIDATED); >catch (Exception e) < e.printStackTrace(); >return isOnline; >

Strength: 1. could run on UI thread; 2. fast and accurate.

Weakness: need API >= 23 and compatibility issues.

public static boolean isNetworkOnline2() < boolean isOnline = false; try < Runtime runtime = Runtime.getRuntime(); Process p = runtime.exec("ping -c 1 8.8.8.8"); int waitFor = p.waitFor(); isOnline = waitFor == 0; // only when the waitFor value is zero, the network is online indeed // BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream())); // String str; // while ((str = br.readLine()) != null) < // System.out.println(str); // you can get the ping detail info from Process.getInputStream() // >> catch (IOException e) < e.printStackTrace(); >catch (InterruptedException e) < e.printStackTrace(); >return isOnline; >

Strength: 1. could run on UI thread; 2. you can ping many times and do statistics for min/avg/max delayed time and packet loss rate.

public static boolean isNetworkOnline3() < boolean isOnline = false; try < URL url = new URL("http://www.google.com"); // or your server address // URL url = new URL("http://www.baidu.com"); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setRequestProperty("Connection", "close"); conn.setConnectTimeout(3000); isOnline = conn.getResponseCode() == 200; >catch (IOException e) < e.printStackTrace(); >return isOnline; >

Strength: could use on all devices and APIs.

Weakness: time-consuming operation, can’t run on UI thread.

public static boolean isNetworkOnline4() < boolean isOnline = false; try < Socket socket = new Socket(); socket.connect(new InetSocketAddress("8.8.8.8", 53), 3000); // socket.connect(new InetSocketAddress("114.114.114.114", 53), 3000); isOnline = true; >catch (IOException e) < e.printStackTrace(); >return isOnline; >

Strength: 1. could use on all devices and APIs; 2. relatively fast and accurate.

Weakness: time-consuming operation, can’t run on UI thread.

check with the below set of codes.

public boolean isNetworkAvailable(Context context) < boolean isOnline = false; ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); try < if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) < NetworkCapabilities capabilities = manager.getNetworkCapabilities(manager.getActiveNetwork()); isOnline = capabilities != null && capabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_VALIDATED); >else < NetworkInfo activeNetworkInfo = manager.getActiveNetworkInfo(); isOnline = activeNetworkInfo != null && activeNetworkInfo.isConnectedOrConnecting(); >> catch (Exception e) < e.printStackTrace(); >return isOnline; >

After searching for days and after trying various solutions, some are not perfect some are too LONG, below is a solution suggested by LEVIT using SOCKETS which is PERFECT to me. Any one searching on this solution may consult this post. How to check internet access on Android? InetAddress never times out

Below is the portion of the code with example of task in AsyncTask

class InternetCheck extends AsyncTask  < private Consumer mConsumer; public interface Consumer < void accept(Boolean internet); >public InternetCheck(Consumer consumer) < mConsumer = consumer; execute(); >@Override protected Boolean doInBackground(Void. voids) < try < Socket sock = new Socket(); sock.connect(new InetSocketAddress("8.8.8.8", 53), 1500); sock.close(); return true; >catch (IOException e) < return false; >> @Override protected void onPostExecute(Boolean internet) < mConsumer.accept(internet); >> /////////////////////////////////////////////////////////////////////////////////// // Usage new InternetCheck(internet -> < /* do something with boolean response */ >);

Below is a summary related to the solution Possible Questions Is it really fast enough?

Is there no reliable way to check internet, other than testing something on the internet?

Not as far as I know, but let me know, and I will edit my answer.

Google DNS (e.g. 8.8.8.8) is the largest public DNS in the world. As of 2013 it served 130 billion requests a day. Let ‘s just say, your app would probably not be the talk of the day.
