Problem: Got a new router ,ipads work lg tv works off the internet but my wife and mine,samsung S4 says we are connected to the internet but we can’t google anything, DNS_PROBE_FINISHED_NO_INTERNET, is what comes up

Solution: This type of error not only occurs on smartphones but on computers as well. This is a connectivity relates issue that happens when your device does not seem to connect to the Internet. The first thing you should do is to check if the error occurs when you are using your phone browser ( the stock browser or perhaps Google Chrome) or if it also occurs when you are using certain apps that requires an Internet connection such as Facebook.

If the error message only occurs when you are using your phone browser while your other apps can access the Internet then this may be a browser related issue. Go to your browser setting and clear its cache. For best results you can also go to the Application Manager of your phone and find the browser app. Proceed with wiping the cache partition and data of the app. It’s also a good idea to wipe the cache partition of your phone as a follow up.

If you can’t go online on your browser and on you phone apps then what you should do is to forget the wireless connection between the phone and the router. Restart the router and the phone then connect your phone to the router. You may need to enter the Wi-Fi password if you have one set.

Sometimes an app installed in your phone may also cause this type of problem, especially a security app. To check if this is the case you should start the phone in Safe Mode. In this mode only the default apps are loaded while the apps that you downloaded are disabled. If you can connect to the Internet this time then the problem may be caused by an app installed in the phone, Find out what app this is and uninstall it.

S4 Can’t Change Network Settings

Problem: I’m trying to change my network settings but everytime I go to “network operators” and click on it. It won’t do anything or go to anything I can’t even access my APN. Is there a way to fix this issue?

Solution: This problem could be caused by a glitch in the phone software or it could also be caused by restrictions set in the phone itself. To check if this is a glitch try wiping the cache partition of your phone first. If the issue persists then proceed with starting your phone in Safe Mode. Once your phone is in Safe Mode check if you can now change the network setting. If it is now possible to change this setting then the issue may be caused by an app installed in your phone, possible a security app. Find out what app this is and uninstall it.

If however the problem still persists even in Safe Mode then your last resort is to perform a factory reset. Make sure to backup your phone data before doing this procedure.

S4 Does Not Stay Connected To 4G Network

Problem: First let me start by saying your APN guide was a life saver. I followed  it and was able to get connected to t-mobile with almost no issue. Now I  say almost because, I have a hard time staying connected to the t-mobile network.  I fall off the network a lot and rarely get 4G. Now the times I do get 4G, it’s amazing, t-mobile speed I believe is unmatched. But it’s rare. Is there maybe something that I need to change? I am using an unlocked Samsung galaxy S5 from Verizon.  Any help  will be greatly appreciated!

Solution: Does this issue occur in a specific location or does it occur anywhere you may be? If it’s only in a specific location then there may be some signal issues in the area ( such as when the 4G reception is low) or there may also be some network related issues in the area.

If however the problem occurs in any location you go to then this may be a phone related issue. Try checking first if a certain third party app is causing this problem by starting your phone in Safe Mode. Once the phone is in Safe Mode you should activate the mobile data switch and make sure that your phone has a 4G signal. Try to open a YouTube video and check if the connection remains stable. If your phone stays connected to the 4G network in this mode then the issue is most likely caused by a third party app. Find out what app this is and uninstall it.

If however you are still having the same problem even in Safe Mode then I suggest you wipe the cache partition of your phone. As a last resort you should backup your phone data then do a factory reset.

S4 Does Not Connect To Wi-Fi

Problem: I press on the Wi-Fi I want to connect to.  It begins connecting but drops out halfway through it is doing this for every Wi-Fi.  I was however able to connect to a Taco Bell Wi-Fi but that’s it.

Solution: The problem with your phone connecting to a Wi-Fi source could be caused by the router itself. Try connecting to different Wi-Fi sources and see if this is the case. Sometimes toggling the Airplane Mode also helps in this case.

If the problem does not go away then it could be caused by some form of corrupt data. If this is the case then you should wipe the cache partition of your phone. You should also consider doing a factory reset but make sure you backup your phone data before doing this procedure.

S4 Can’t Access Mobile Data

Problem: New phone. No mobile data. Maybe the phone is defective. Have not been able to access mobile data at all. Tried different sims which had no problem in other phones. Tried factory reset. Took out batteries etc. Everything else is fine– wifi etc, but mobile data won’t work no matter what. Will return to vendor  if can’t fix.

Solution: Since this is a new phone I’m pretty sure that the phone’s APN has not been set yet. This setting allows your phone to connect to your mobile data subscription. Check on this setting first and make sure that it matches the APN setting your network is using as different carriers use different APN settings. Make the necessary changes in your phone if necessary.

S4 Wi-Fi Signal Low After Lollipop Update

Problem: Ever since I upgraded the OS to lollipop my wifi signal is low. I have to be in the same room for the wifi to be 3 or 4 bars. I took the case off and it it’s better but not by much. I did everything normal to try and fix it. Restart, soft restart, then factory reset. Nothing has changed. My phone is not working as fast either. There a 2 sec or more delay.

Solution: If the issue persists after a factory reset then this may either be caused by the update itself or the Wi-Fi router. Try restarting the router and see if there is any improvement. You should also try to connect to a different Wi-Fi source and see if the issue is still the same.
