S4 Not Going Online On Wi-Fi

Problem: I have wireless at home and laptop goes online (Chrome) without problems. Cell is connected and has, up until yesterday, gone online without problems. As of yesterday, despite being connected to wifi, cell will not go to internet. The blue loading line, goes about 1/4 inch and “”this webpage is not available”” shows up. DNS failure — turned off prefetch, but it didn’t help, so I turned it back on.

Solution: In cases like this you should first try to reset the connection between your phone and your home wireless network. To do this you should turn on the Wi-Fi switch of your phone then long press on your home wireless connection then click on forget network. Once the network has been forgotten restart your router. Scan for your wireless network again and connect to it.

Once your phone is connected check if you can go online with it. Open your social media apps and browser and see if you can go online. It’s very likely that the issue will disappear however if you are still getting a DNS failure error ( I’m assuming when you are using the Chrome browser on your phone) then start your phone in Safe Mode. In Safe Mode connect your phone to your wireless network. If the DNS failure error does not occur in this mode then it’s likely that a third party app installed in your phone is causing this problem. Find out what app this is and uninstall it.

S4 DNS Probe Finished No Internet Error

Problem: I recently bought a  Verizon Galaxy S4  and set it up for straight talks BYOP program,  the mobile data will work for maybe 3-4 minutes then cut off,  showing a DNS probe error but still picking up a full 4g signal. I’ve contacted straight talk,    who have not been able to fix the problem,  I’ve tried a new sim card,  a few apns that I’ve found on the internet,  but no dice,  hoping you can help.

Solution:  Since Straight Talk was able to look into this problem then we can assume that the issue is not with their network. You were also able to isolate the SIM by replacing it and checking if the problem is caused by the APN setting which didn’t resolve the issue. What we need to check next is if the issue is caused by an app installed in your phone. Before checking on this make sure to use the correct Straight Talk APN settings on your phone.

Once you have made sure that you have the  correct APN settings start  your phone in Safe Mode. Try going online and see if the DNS probe error still occurs. If it doesn’t occur then a third party app installed in your phone may be causing the problem. Find out what app this is and uninstall it.

If however the problem still persists even in Safe Mode then We should assume that this may be caused by a corrupt phone software. You should proceed with backing up your phone data and doing a factory reset. Once the factory reset has finished you may need to enter again the Straight Talk APN settings before you can go online.

S4 Wi-Fi & Bluetooth Greyed Out

Problem: I hadn’t installed Any apps or done anything different before my Wi-Fi and Bluetooth buttons grayed out. I click on them and they still don’t come in. I’ve done a hard reset and soft rest. I’m hoping it’s not a software issue but I’m not sure of what you do next.

Solution: Usually if the Wi-Fi button is greyed out you will need to do a factory reset to verify if the problem is not software related. In this case though you already performed the factory reset which did not resolve the issue. It is most likely that this may already be a hardware related problem. You can however try to flash your phone software using Odin with its stock firmware ( which you should download). Some owners of this device claim that flashing the phone software resolves this issue. If flashing the phone software does not work then you need to bring your phone to an authorized service center and have it checked.

S4 4G Stopped Working After Root

Problem: So i bought a samsung s4 from my friend and my 4g would work but after i rooted it using kingo root my 4g stopped showing on the status bar and doesn’t work.

Solution: Try to turn off your phone and take out the SIM card. Leave the card out for a few minutes then insert it back into your phone and turn it on. If you are still not getting a 4G signal then access your phone network mode settings. The choices are  LTE/GSM/WCDMA (auto connect), GSM/WCDMA (auto connect), GSM only or WCDMA ONLY. Make sure to choose LTE/GSM/WCDMA (auto connect). You should also check if your phone is using the LTE APN setting of your network.

S4 Unstable Wi-Fi Connection

Problem: To whom it may concern, I have owned a Samsung Galaxy S4 for T-Mobile for over 7 months now with no problems at all until recently I had to get a new modem/router installed by my cable provider. Immediately I noticed my phone’s Wi-Fi connection decreased a lot and some games on the phone refuse to open. When I check the Wi-Fi connection settings next to the name of my router it says “Connected” then sometimes says “Checking quality of connection”. When I take my phone to work and use the Wi-Fi there or any public Wi-Fi, I do not have any problems at all and the connection speed works flawlessly.  However, Every other device from tablets, laptops, smart TVs and game consoles connect to the modem/router just fine at home and work great. So what gives? I recently did a factory reset just to see if that would fix the problem and it did not. Then deleted the cache partition from the system boot and still not help. The only thing I can think that is causing the problem is the router but not sure why everything else is working and not my S4. I have even gone through the settings on the router to make sure everything is working good and I did not see anything out of the ordinary. Thank you. My Galaxy S4 is currently working on Android 4.4.4 (Kitkat) No custom roms or rooting. Model Number : SGH-M919

Solution: There seem to be some connection related issues between your phone and the router. Try to forget the connection from your phone. Scan for the connection again and connect to it.Check if the issue still persists. You should also go to the advanced Wi-Fi settings of your phone and make sure that the Wi-Fi frequency band is set to automatic.
