Galaxy S7 wifi keeps dropping, won’t connect to printer, other issues

Hello and welcome to another #GalaxyS7 troubleshooting article. This post addresses some connectivity and wifi problems that some S7 users have reported. We hope you’ll find it useful.

Problem 1: Galaxy S7 wifi keeps dropping

Hi. For some while now (a few months) I’ve had a problem with my phone dropping any internet connection it makes after a very short while. Sometimes it will hold for a couple of minutes but sometimes it drops out within a few seconds. It’s driving me crazy. I’ve tried reinstalling the home internet but, to be honest, it’s not just the home internet it does it with, it’s any, anywhere! I can connect but it just doesn’t hold the connection. It does it whether I’m actually using the internet or not so I can be in the middle of something and suddenly I have no internet. Any clues as to what’s going on?  It never used to do it when I first bought the phone and I guess it’s happened sometime over the past year or so. Phone is a Samsung Galaxy S7. Any help you can give would be appreciated. I don’t use my phone provider internet, just home and any freely available on my travels. Thanks. — Pam Pantzer

Solution: Hi Pam. We gather you’re only having an issue with your phone’s wifi since you mention you’re not using your phone internet at all.  To fix the problem, these are the things that you can try:

Check if a third party app is the cause

We don’t have a complete history of your device so we can’t be sure if one of your downloaded apps is causing the problem. For an issue like this, one of the possible things that you should  check is the possibility that an app may be behind the trouble. To check, you want to restart your S7 to safe mode. In this mode, all third party apps will be blocked so if the issue won’t occur, that’s a clear indicator that an app is to blame.

To restart your phone to safe mode, follow these steps:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

One important thing to remember: safe mode won’t fix the issue. Instead, it’s a diagnostic tool that you can use to know if an app is causing a problem or not. It won’t pinpoint which of the apps is causing it. If you think an app is causing the problem, you must try to uninstall apps one by one until you’ve identified the culprit.

Install app and Android updates

The next best thing to do is to ensure that you install any pending updates for all apps and  operating system. Updates not only bring improvements and changes but also solutions to known bugs. We don’t exactly know what’s behind your problem but installing updates should be a highly recommended step.

To ensure that your apps are up-to-date, follow these steps:

  1. Open Play Store app.
  2. Tap Menu icon at the top left.
  3. Tap My apps & games.
  4. Hit Updates All.

To see if there’s any available Android update, follow the steps below:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download updates manually.

Wipe the phone via Factory reset

If the first two suggestions above won’t fix the problem at all,

This is a drastic solution so you need to back any important data you may have in your phone before you do it. Once you’re ready, follow the steps below to factory reset your device.

  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 data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ 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.

Get a phone replacement

After doing a factory reset, make sure to check how your phone’s wifi work right away. Be sure that you don’t install any app during this time to eliminate the possibility of a bad app interfering with the system. If the issue remains after doing that, there must be a hardware problem behind the trouble. Contact Samsung (if phone is under warranty) to see if they can replace the device for you. Otherwise, you either have to just put up with it or find a way to get it replaced.

Problem 2: Galaxy S7 won’t connect to printer

I can connect to the wireless internet, but it won’t connect to my printer. This started happening this week before I had no problems. I added a direct connection on my phone for the printer, but it just comes back internet is not available. I have my printer connected wirelessly to my internet through my computer connection. I want to delete the direct network connection to my printer because my printer is not connected to that address. I hope this makes sense and you are able to help me. Thank You. — Tamara

Solution: Hi Tamara. In order not to waste your time, we suggest that you check printer’s documentation so you’ll know how to connect it to your phone. Your description is obviously incomplete and there’s a lot of critical information that we don’t have to be able to help. For example, you did not even bothered mentioning the brand and model of you the printer. Things such as these are key to helping support teams like us help you efficiently. Not every out there runs the same software. Some may be compatible with some devices while others may be problematic or won’t be able to connect at all. If your printer does not have clear instructions on how to do what you want, contact the printer manufacturer for help.

Problem 3: Galaxy S7 keeps connecting to any available wifi even if wifi is turned off

I have a Galaxy S7 that only stays connected to my home WiFi, when I am in range.  If I turn off WiFi for security when I leave my house, my phone keeps connecting to any unsecure WiFi that it can find.  It will stop doing this after I turn off the WiFi several times.d I am considering getting a Galaxy S8, but by the posts I am seeing here, it sounds like that phone may have the same issues.  Any suggestions? — Mary Rosenquist

Solution: Hi Mary. There may be a software issue causing this glitch so kindly do a factory reset to see if it will make any difference. Just like what we tell Pam above, be sure to allow your phone to run without apps for a few hours so you have more than enough time to see if it fixes the issue or not. If the problem remains after a factory reset and without apps installed, you’re looking at a hardware issue. If wifi works normally after a factory reset but returns to its problematic state afterwards (after installing apps) one of your downloaded app must be to blame.

Problem 4: Galaxy S7 can’t connect to 4G network

I have a Samsung Galaxy S7. Last year I used it while traveling in South America (Chile). I purchased a local SIM card for it and it worked great, 4G perfect. I brought the phone back to the US and used it with both Verizon and Straight Talk SIM Cards, again no problem with 4G. Now, I’m back in Chile and have the Chilean SIM card back in the phone and suddenly I can’t get 4G (i’m still getting 3G). The CDMA/LTE wireless network setting does not work. It says “searching,” but then asks me if I want to go back to Global. I’ve spent hours at the Cell Phone stores here, we’ve verified that the chip works in other phones, so it seems to be something with my phone. I just did a factory reset, that did not fix it. Any advice would be much appreciated… a new phone is so not in my budget :(Â  I can send any screen shots, or other info. Thanks!!! — Linda

Solution: Hi Linda. Are you using the same SIM and network right now just like during your first visit? If not, then there’s a chance that your phone may not be compatible with the current network’s 4G system. It’s also possible that the region you’re in right now does not have 4G/LTE coverage for some reason. To know more about the possible reasons for your problem, contact the technical support team of the network and let them help you troubleshoot.
