How to troubleshoot Samsung Galaxy S7 Wi-Fi connectivity issues & other Internet related problems

The new #Samsung Galaxy S7 (#GalaxyS7) has a Wi-Fi bug. It’s a minor one but nevertheless annoying. It affects the syncing capability of the phone especially Gmail. Samsung already acknowledged it and even started rolling out minor updates to fix it and in the U.S., #Verizon followed suit. For sure, other carriers and service providers will roll out updates sooner than later.

It is a Wi-Fi bug and if you get Internet service through mobile data, you won’t be able to experience this annoyance. If, however, you have Internet-related issues while using data, then that’s a different story but I will also address that one here.

The first part of this troubleshooting guide is to provide you with workarounds so you’ll be able to continue using your phone despite the bug that keeps bugging you. At the later part of this article, I will address some of the Internet-related concerns Galaxy S7 owners reported.

Before anything else, for our readers who may be experiencing other issues, please visit our Galaxy S7 troubleshooting page. We list down every problem we address each week so there’s a chance your concern has already been addressed by our team. Try to find issues that are similar to yours in that page and use the solutions we provided. If, however, you need further assistance, you can always reach us by completing this questionnaire. Please provide as much details as possible so we can give you accurate troubleshooting guides and/or solutions.

Workarounds for the Galaxy S7 Wi-Fi bug

These aren’t solutions but workarounds or temporary remedies so you can continue using your phone despite the symptoms the bug is showing. Again, the bug is minor but very annoying especially if you rely on Wi-Fi to connect to the Internet. So, if you noticed your phone is showing one or two of the signs below, try the workarounds I cited:

Symptoms

  • Gmail not syncing properly
  • Wi-Fi is very slow
  • Wi-Fi keeps disconnecting and reconnecting
  • Connection lost even if the phone isn’t idle
  • Wi-Fi On/Off switch grayed out

Workarounds

  1. The first thing you should do is to restart your phone. The bug is actually triggered when the phone is being used; it doesn’t initiate during boot up. So, basically, the problem will be temporarily fixed when the phone is rebooted.
  2. If you don’t wait a few seconds of booting up, there’s another thing you can do–turn Wi-Fi off and then turn it back on. The connection gets refreshed when the device reconnects and it’s actually one of the most used workarounds for this bug, however, the problem seems to manifest again a lot quicker than when you reboot your phone but anyhow, it helps.
  3. Disable Bluetooth. Some users reported that Bluetooth may be one of the triggers of this bug as the problem often occurs when it is enabled. So, try disabling it and see what happens.
  4. Disable other location services. If you often use GPS and/or other related services, this issue will be a pain because in order for the Wi-Fi to work flawlessly, location services must be disabled. Others also said uninstalling apps that use location services will also temporarily fix the problem.
  5. Check for firmware update and download it if there’s one. Again, a few service providers may have already rolled out updates that may patch this problem, so try to check for it from time to time.

 

We don’t know how widespread the problem is but if you’re one of the unlucky ones, at least, you can do something about it. I hope that this simple guide can help you until help arrives.

Internet Problems with Galaxy S7

Here are some of the Internet-related problems we received from our readers:

Q:I have 2 new Samsung S7 phones. When I turn hotspot on my laptop connects fine to mobile 1 and has access to internet. When I try to connect laptop to mobile 2 hotspot it connects but will not give me internet.   Data is turned on and I have internet access on both phones. My laptop internet trouble shooter tells me it is disabled locally.

A: All we need to do is find out whether the problem is with the phone or your laptop. So, here’s what I need you to do:

  1. Make sure the phone you’re having issues with has internet connection.
  2. Turn on its hotspot.
  3. Now, connect your other phone to it and see if it can get service.
  4. If the internet works on the other phone, it’s most likely an issue with the laptop but it’s more of a compatibility issue than anything else.

But the thing is, either your phone can get internet connection or not, you still need to bring the phone in for checkup. It’s a new phone and if I were you, I would ask for a replacement.

Q:New Samsung galaxy S7, SM-G930F, can’t log into some websites. I put in password etc. and the page resets back to the login page. I use chrome but have tried the native internet too. I’m still using my S6 as the second phone and it logs in no problem.

A: If it can log in to other websites, then there’s no problem with the phone. The issue may be in websites you’re trying to log in to but we really don’t know for sure. It could have been a lot helpful for us if you gave us a hint what websites you were trying to log into. I also think it’s not an issue with either Chrome or the stock browser. Try calling the tech support of the websites and inquire about the problem. May be they were having service maintenance during the time you tried to log in.

Q:My new Galaxy S7 can’t connect to the internet using data. I have subscribed for an unlimited data but can’t use it. I just got the phone and the tech already registered in to their network so I now have text and calls but no internet. How can I fix this?

A: I understand you already got the device provisioned and it already has all basic services except Internet. Well, you need to set your phone to connect to your provider’s network but if the rep already did that, then all you have to do is enable mobile data. Once enabled, you should be able to get internet service, otherwise, it will be the APN that has issues–either it was configured incorrectly or haven’t been configured at all. I suggest, you call your provider again and report this problem. The rep should be able to help you with it.

Q:I have an S7. Yesterday it froze and I had to press and hold the Volume Down and Power keys to reboot it. But once it was ready, I wasn’t getting internet and the Wi-Fi icon was white. When I went to Settings to turn Wi-Fi off, it was greyed out and I can’t do a thing. I already rebooted many times but the problem remained. What should I do?

A: It must be the cache that got corrupted when the system crashed. So, try wiping the cache partition via recovery mode:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Q:I downloaded a bunch of apps and then there were these pages that kept popping up about some apps that could help me clean my phone of viruses. I don’t want to install those things but they kept popping up so I decided to try one but after the installation, the phone froze and I could no longer connect to the internet. What is the problem?

A: You may have installed some malicious apps so you need to uninstall those. Since you voluntarily installed one, you should be able to remember its name. Now, if you can’t do something on your phone because ads keep popping up, then boot your device in safe mode first and uninstall the app from there:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

Q:My Galaxy S7’s screen blacked out all of the sudden and it took me hours to bring it back on but this time, it started to freeze and lag a lot of times so I knew from that moment on something was wrong. I just continued to use it but it became really slow and the internet connection is really slow as well. Please suggest something I can do to fix this problem. Thanks.

A: Honestly, we don’t know what caused the screen black out. I believe it was a system crash you experienced and it must have been caused by something–it could be an app, a firmware glitch, etc. Since we don’t have a hint what’s causing all this, there’s one thing I want you to do; do the master reset. I’m not sure if you’re still within the replacement period but after the reset and the device still keeps lagging and freezing, you need to have it replaced or, at least, fixed by your provider’s technician. Here’s how you do the master reset on the Galaxy S7:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

  1. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  5. The phone will now reboot longer than usual.
