Connecting to a Wi-Fi hotspot is the cheapest way of connecting to the Internet not to mention the cheapest and most of the time free. It is therefore, very important that your Samsung Galaxy J7 or any smartphone for that matter is able to connect to any Wi-Fi network anytime, anywhere. But what would you do if one day, your phone won’t connect to your home Wi-Fi network anymore? What if you have to open that very important email from your boss after work but you can no longer connect to Starbucks’ Wi-Fi?

Ever since we started supporting Android devices since 2012, we already received thousands of complaints from our readers and basing from those complaints, Wi-Fi issues are more often minor provided that the firmware isn’t tampered and the device didn’t suffer from both liquid and physical damage.

Have the technician check it for possible damage.

Troubleshooting Galaxy J7 that can no longer connect to Home Wi-Fi

The reason why you setup your home Wi-Fi is so that you have a fast and stable internet connection. That is why it is such a disappointment when a phone as good as the Galaxy J7 fails to connect to your own home Wi-Fi. In this section, let’s try to troubleshoot your phone and your network devices to see if we can make your J7 connect to your network.

Step 1: Reboot your phone

This must be the first thing you have to do especially if it’s the first occurrence of the problem. Rebooting the device will eliminate all possible minor firmware and hardware glitches. There’s always a bigger chance your problem will be solved by this very simple procedure.

After the reboot, try to connect your phone to your Wi-Fi network and if the problem persists, then continue with your troubleshooting.

Step 2: Powercycle  your network devices

Another possibility why this problem occurs is when your network devices such as your modem or router needs to be restarted to be able to function well again. These devices also freezes and when it happens, they need to be re-initialized. So, unplug them from the power source, wait for a minute and then plug them back in.

If your device is still unable to connect to your home network, then it’s time to go after the firmware.

Step 3: Boot your phone in safe mode and reconnect

Based on our experiences as well as some of the reports from our readers, the Wi-Fi radio and its services can be affected when some apps crash, even third-party ones. Therefore, before going after the firmware, you need to verify it’s not an issue with your apps. Boot your J7 in safe mode and try to connect your device to the same network.

  1. Press and hold the Power button (located on the right) until Phone options is displayed then release.
  2. Select and hold Power off until the Reboot to Safe Mode prompt appears then release.
  3. Tap RESTART. Note: This restart process may take up to one minute to complete.
  4. Upon restart, Safe mode appears in the lower left of the unlock/home screen.

If the problem persists even in diagnostic state, then it’s time to go after the firmware itself.

Step 4: Delete the system cache

Caches get corrupted more often than you think. In fact, this problem could be just a result of it. Since we cannot delete specific caches, we need to wipe off the directory where all these caches are saved–the cache partition. So, in this section, you will learn how to reboot your J7 into the recovery mode and wipe the cache partition. Don’t worry, this procedure doesn’t have any adverse effects on your phone and the caches that were deleted will be replaced with new ones. Here’s how…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

After deleting the system cache try to connect your phone the network you’re having problems with. Should the problem remain, you have no other choice but to reset your phone.

Step 5: Perform Master Reset your one your Galaxy J7

The reset will delete all files and data in your phone as well as bring the device back to its original or factory default settings. Before you follow the steps below, make sure you backup all your data and files as they will be deleted.

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off your Galaxy J7.
  3. Press and hold the Volume Up button and the Home key, then press and hold the Power key.
  4. When the device logo screen displays, release only the Power key
  5. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  6. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  7. Press Power button to select.
  8. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  9. Press Power button to select and start the master reset.
  10. When the master reset is complete, ‘Reboot system now’ is highlighted.

Galaxy J7 is connected to a Wi-Fi network but doesn’t have connectivity

Question: Can you guys please help me. My J7 is connected to a Wi-Fi network but I still can’t connect to the internet. My emails don’t work, I can’t stream music and videos. What gives?

Answer: Well, just because you’re connected to a Wi-Fi hotspot doesn’t necessarily mean you get internet connectivity.

Galaxy J7 shuts down or reboots while connecting to Wi-Fi

Question: This problem just started recently. My new Galaxy J7 either turns off or reboots while I’m connecting to Wi-Fi hotspot regardless whether it’s my home network or a free public hotspot. What seems to be the problem? Can you help me fix it?

Answer: It’s either caused by a third-party that automatically pulls updates from servers the moment the phone is connected to a Wi-Fi network or a minor firmware issue. Try booting your phone into Safe Mode first and connect the device to a network. If the problem still persists, then you have to reset your phone to eliminate the problem.

Galaxy J7 freezing while browsing using Wi-Fi

Problem: I have the J7 Galaxy phone I bought brand new. So far so good but I noticed that there are times when the phone freezes or lags when I’m browsing the web through Wi-Fi. I can’t seem to understand the reason why it’s doing this but if you guys know about this and have a workaround, please help me.

Answer: The same as the previous problem, it could either be an app issue or a problem with the firmware. So, isolate the problem first by booting the phone in safe mode and observing if the phone still freezes or not.

Another possibility is that the problem is due to the web browser you’re using. That being said, try to clear the cache and data of the browser you use and see if that makes a difference. If not, then try to reset your phone.

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Application manager
  5. Tap the suspected app.
  6. Tap Storage.
  7. Tap Clear data and then tap OK.
  8. Tap Clear cache.

Galaxy J7 became unresponsive after connecting to Wi-Fi

Problem: Hey guys, first of all, thanks for taking time reading my problem. It’s about my Galaxy J7. The problem is that there are times when it just freezes and won’t respond after connecting to Wi-Fi. Thanks goodness it has a removable battery so every time it happens, I just pull the battery out and place it back in. It will work until the problem re-occurs. What do you suggest I do to fix this problem?

Answer: Apparently, it’s a firmware issue that’s affecting the general performance of your phone. For this, the best thing you can do is master reset your device to see if the problem still persists after that and if so, then you may need to check if there’s an available update. If there’s none, have the tech take care of the problem for you. The firmware may need to be re-installed.
