How to fix Wi-Fi issues on your Samsung Galaxy S6 and S6 Edge


Wi-Fi connectivity has become one of the indispensable core features of any smart device including the vaunted Samsung flagships, Galaxy S6 and S6 Edge. As Wi-Fi hotspots sprouts all over, it is hard to imagine using a $500 device without Wi-Fi functionality. While problems relating to Wi-Fi pales in comparison to other popular issues like app crashes or operating system failures and glitches, we are still getting a decent amount of questions and requests for support from time to time. We hope that this post will answer some of the queries sent to us.

Before you go nuts trying to fix your phone, consider boosting your wifi connection at home using these wifi range extenders.

Problem #1: Samsung Galaxy S6 won’t pull up Wi-Fi

If you really can help me I would appreciate it. I just got this phone today and while my husband can find out Wi-Fi connection at home on his devices this phone won’t even pull it up so that I can connect to it. After countless hours on the phone tech support could not help me. Please help! — Shaylie

Solution: Hi Shaylie. We are not sure what you mean exactly by “phone won’t even pull it up so that I can connect to it” but if the device is missing its basic Wi-Fi capability, something is definitely wrong with it. If you can secure a replacement, please do so at your earliest convenient time.

In case we misinterpreted what you mean, please get back to us with more details.

Problem #2: Samsung Galaxy S6 does not show notifications real time when Wi-Fi in on but screen is off

Hi. When i activate Wi-Fi, i don’t get my notifications real time unless i open, for example, WhatsApp. if I have the Wi-Fi activated and the Galaxy display is off, i don’t get the notifications unless i open WhatsApp. That doesn’t happen to me when I’m using mobile data; the notifications get on real time and i don’t need to open the app. i will appreciate your help. Thank you. — Andres

Solution: Hi Andres. What type of notifications are we talking about here? Kindly specify what particular notifications are you missing. Otherwise, you can do a factory reset to bring the phone to its defaults.

Problem #3: T-Mobile Samsung Galaxy S6 can only send text and calls when connected to Wi-Fi

I bought my phone 3 months ago.  It has been working great except sometimes it drops internet at my house (no Wi-Fi & I live in rural areas) occasionally.

For about a week it had said I needed a wi-fi to download a large software update. I forgot about it until three days ago I began having problems making calls, no internet & battery seemed to go a bit faster. But still could send texts although sometimes took a while. So went to a T-Mobile store & used their wi-fi to download the large software update. After that I had internet in the store (wi-fi), could make calls and send texts.

When I go home nothing worked. I went to places where my phone normally works 100% of the time and it doesn’t. IT now only works when I have wi-fi access.

I am getting no mobile network error and mobile data turned off. But when I checked the mobile data was turned on. I went back to T-Mobile and  they did factory reset and even changed out SIMs.  It was again working in the store but when I left, phone calls were right away not working well through Bluetooth and then no internet etc.

I am now on a two week wait list to have my phone replaced with a refurbished one. I would love to avoid this and get mine working. I think the key issue is that it is saying my mobile data is turned off but when I looked at it – it is for sure turned on!  Please help. Thanks. — Christina

Solution: Hi Christina. The carrier-specific update from T-Mobile may have been changed to effect these problems you are having. If you have already tried resetting the phone to its defaults, we don’t think there’s still anything that you can do at your end to fix the problems. We are certain the reason has something to do with that update because all your problems are network-related–internet, mobile data, calls. T-Mobile should fix the issue for you as we have no way of diagnosing where the error begins in the first place. Based on your problem description, you don’t have these issues when you are connected to a Wi-Fi network.

Please try calling T-Mobile’s hotline and ask for their technical support team to help you. Store attendants may not be trained to diagnose any network-specific problems that’s why they almost always recommend a replacement as tast resort. On the other hand, their technical support team on the phone may be able to help you check some T-Mobile-specific items that we are not aware of. There may be some provisioning issues that needs to be addressed here including giving the phone the proper APN settings.

Problem #4: Wi-Fi connected Samsung Galaxy S6 unable to create a Gmail account

Hello, okay so I recently just bought my Samsung Galaxy S6 and I connected to Wi-Fi. However when I made my Gmail account, it said it’s having trouble connecting to the server. I don’t know a lot about electronics so I’m not sure what to do and I’m new to Androids! I’d greatly appreciate the help!(: 

Thank you. — Alivia

Solution: Hi Alivia. Make sure that your S6 is connected to the internet first before attempting to create a Gmail account. You can do so by using an internet-based app or by going a website like the using the phone’s browser.

The error message you are getting is an indicator that the device may be connected to a local network like your Wi-Fi but not to the internet.

Problem #5: T-Mobile Wi-Fi calling not working when connected to another Wi-Fi network

Hi. I was staying a week at a place where there was poor cellular, T-Mobile, service. However the Wi-Fi network was very good and my Galaxy S6 connects just fine. All apps and internet browsers work. I am unable however to make any Wi-Fi calls or texts. The error message said unable to connect for Wi-Fi calling. The Wi-Fi network did not require a password and apparently this is the problem according to T-Mobile after having me try a factory reset which as we all know is excruciating!!!

I called Samsung and they said there is nothing wrong with the phone and know nothing about why it is doing this. When I got home, I selected in my settings to use only Wi-Fi (I have a secured password network) and no cellular service and was able to make Wi-Fi calls and texts.

Is there something else that can be done to be able to connect in open Wi-Fi networks too? Thanks. — Heidi

Solution: Hi Heidi. T-Mobile’s Wi-Fi calling feature has to meet some requirements before it can work on their Wi-Fi calling-capable phones. For one, the local network you are trying to connect to must allow such feature in the first place. You need to work with the network administrator to check this out.

Also, Wi-Fi calling feature needs a minimum of 25 Mbps and you must be about 15 feet from the router to work properly.

Based on T-Mobile site, these are the technical requirements in order for Wi-Fi calling to work:

  • Access to a Wi-Fi router with a high-speed internet connection
  • A Wi-Fi calling-enabled smartphone
  • A valid 911 address on file

Problem #6: Galaxy S6 syncing and loading problem when connected to Wi-Fi

So, I have used the iPhone on AT&T since its launch, I decided I needed a change and about 2 months ago went with the Galaxy S6.

I found it to have a few minor issues with apps and a much lower quality battery than the iPhone which I decided I could live with so continued with the device, connectivity was ok and the apps were ok.

Now out of nowhere I started having an issue where when connected to WIFI anywhere certain pages do not load or they load  very slowly. ex: Facebook will either not load or images do not show up.  My mail application will not sync on WIFI. I can do common web searches and use other Apps that require connectivity.

I have found that if I want my Email, Facebook and other affected apps to load properly I need to shut down and restart WIFI and all of a sudden they work for a few minutes syncing my mail and allowing images to load, then within minutes nothing will sync properly again and FB images and pages will not load again.

I have tried the RAM reset, I did a full phone reset and nothing seems to help.  When I am using LTE mail and Facebook sync and load fine, but if I connect to WIFI they will stop within minutes unless as I said I shut off WIFI and restart it.

Do you know of any known issues or workarounds to help me with my issues? Thanks. — CL

Solution: Hi CL. We notice that you did not mention checking your Wi-Fi connection speed. Keep in mind that if your Wi-Fi connection speed is slow, or if the network is congested, it’s understandable that syncing and/or loading of apps may be slow too.

Problem #7: Galaxy S6 cannot connect to work Wi-Fi

Hi there. I have had my Samsung S6 for a couple of weeks now. Prior to that I had a Samsung S3 which I used to connect to the WIFI here at my workplace fine. Since changing to the Samsung S6 it won’t let me connect to the staff Wi-Fi here. I have no problems connect to our home Wi-Fi.

I have contacted our I.T people to check things out on their end and it turns out it is not a fault with them but my phone. These are the following things I have done to try and help the connection:

  • Power off to reset the phone
  • Rebooted my phone
  • Forgot the WIFI name
  • Had another staff member try and use there log in details on my phone
  • Changed my password

The error that comes up when I am trying to connect is:

Incorrect password & authentication error.

My I.T team have double and triple checked that it is on all the correct inputs.

Please help find a solution. Regards. — Lady

Solution: Hi Lady. If your IT team, who has access to router and network settings, cannot figure the problem out, this must be a unique phone problem. Frankly, we can’t think of any other solution other than factory reset. Please try that and if it helps.

Problem #8: Galaxy S6 cannot send text message over home Wi-Fi


I recently got the Galaxy S6 and have almost no reception in my apartment. My texts are supposed to send over Wi-Fi but they won’t. I went into the Verizon store and when I was connected to their Internet  (and in airplane mode) they sent, but when I’m connected to my Internet they won’t, and I have a strong signal and everything else works. At Verizon they told me they can’t fix a problem that isn’t there so I’m not sure what to do!

Thanks. — Julie

Solution: Hi Julie. We need more information from you to be of help. Things like the app you’re using when sending and receiving texts, error messages, etc are useful. Please be as detailed as possible when contacting us again.

Problem #9: Galaxy S6 keeps on turning off random features including Wi-Fi

Hello. My name is Lewis and just wondered if you could help with my query. My S6 Edge keeps turning things off by itself when I’m not even using the phone. The most common ones are the battery percentage and the Wi-Fi — they just randomly go off even when my phone has being idle for an hour or so. I then have to manually turn them back on when i realize i checked all the relevant settings and everything seems in order. i appreciate it’s only a small matter but very annoying and I’ve only just switched over from iPhone and am having second thoughts also due to the battery draining rapidly when idle and when in use. I can barely make it through the day and this is with a lot of things turned off. Any help would be appreciated. Thanks. — Lewis

Solution: Hi Lewis. We recommend that you simply perform a factory reset to ensure that the device runs on clean firmware. If you haven’t tried this before, here are the steps:

  • Shut down your Galaxy S6.
  • Press and hold these buttons: Power, Volume Up, and Home.
  • Once the blue recovery menu screen appears, use the volume rocker to navigate to Wipe Data/Factory Reset option..
  • Scroll down to Yes, delete all user data, then press the Power button again.
  • Wait for the system to complete the process and until you see Data Wipe Complete notification is shown.
  • Press the Power button once again to restart the phone back to normal mode.

Problem #10: Samsung Galaxy S6 keeps on losing Wi-Fi connection and showing authentication error

Hello. I was wondering if you knew what is going on with my phone. I was on the internet then out of nowhere my phone loses Wi-Fi connection. I try to connect back then it keeps saying authentication error. My home Wi-Fi is the only Wi-Fi i am not able to connect to. Also shortly after, a picture of a white page pops up and has a whole bunch of words on it. Next time it does that i can screenshot it and figure out what it is about. Again my phone is a Samsung Galaxy S6. Thank you for your time. — Dino

Solution: Hi Dino. Your first task is to identify the origin of the problem. These are the things that you can try:

  • Verify if other wireless devices like smartphones, laptops, tablets, etc are experiencing the same problem. If they are, the issue must be on your local wireless network.
  • Perform a soft reset. This is the equivalent of turning the phone off and removing the battery from the device. Since you have a non-removable battery pack, simply press and hold the Power and Volume Down buttons for about 10 seconds.
  • Forget the network. Refreshing the network by going under Settings>Wi-Fi and tapping “Forget this Network” sometimes helps.
  • Verify is your phone connects to other Wi-Fi networks. This is to ensure that there’s no hardware trouble behind.
  • If nothing works despite having done all these, consider performing a factory reset.

Problem #11: Unable to auto-update Galaxy S6’s date and time over Wi-Fi

Hey Droid Guy.

Model:  Samsung S6, (sm-g920v)

Carrier:  Verizon

OS:  v5.0.2

I am running in Airplane Mode and Mobile Data=off because I am traveling out of the country. I can successfully use Skype over Wi-Fi, but the clock will not auto-update both the “date & time” and “time zone”.

Is this possible over Wi-Fi, let’s say hotel Wi-Fi?

Thanks. — TLPenn

Solution: Hi TLPenn. You must have enabled the Automatic Date and Time option under Settings>Date & Time. Simply disable this option and manually set the phone’s date and time to your locale and you should be all set.

There’s no option to auto-update the phone’s date and time via Wi-Fi so this is the only way to go.

  1. I also have same issue as #10. I have tried everything, from turning off the phone for a few minutes and turning back on, to a network reset to a factory rest and it still keeps saying Authentication Error. I does this with my home network as well as other WIFI connections. Sometimes, for the other WIFI connections, it will say “connected to WIFI, internet may not work”. This has been going on since October, and has made me go over my data twice.

  2. Mine and my wife’s S6s have both started having trouble connecting to the wi-fi since the update before Christmas 2017, both at exactly the same time. Other devices are unaffected, and our router has not changed, so it has to be something introduced either by Samsung, Google, or our carriers. Is it a coinicence that our contracts are up? Somehow I doubt it.

  3. my samsung s6 is connected to my wifi but it says no internet . i turned it off and on and it keeps happening . also turned off and on my wifi still doesnt work

  4. After the last Samsung update on my S6 active the switch from wifi to cell and back is even more unreliable. I also confirmed this with AT&T (my service provider). On my tech support call we agreed that the best way to connect to wifi is to first set you Mobile data to off (otherwise you can’t tell if you’re using cell data or not, part of that last update. then go to your wifi network list and pick your network. It seems to work after you do all of these things.

  5. Could an android update cause there to be wifi connection problems? I have had my Samsung Galaxy S6 phone for over 2 years, with the same wifi router in my room for that whole time. I have never had problem connecting to wifi using my Netgear wifi router. My laptop computer works perfectly fine connecting to the Netgear wifi. Why suddenly does my phone not connect? I have tried reseting the router, forgetting the netgear on my phone, reseting my phone, etc. PLEASE HELP!

  6. I have a mesh WiFi network at home (TP-Link). My Samsung S6 will drop the wifi connection randomly with the message “authentication error” and attach to the cellular network. It has no problems logging in when I stop and start the wifi, but after a while it will disconnect and attach to cellular. This happens 10-20 times per day and extremely frustrating during Skype calls. None of the other devices (iPhones, iPads, computers) have the same issue. From the blogs, it looks like this is a common problem with Samsung including with the S8 and it has not been fixed in years. I have now given up and will purchase the iPhone 8. I have to say, I’ve been using the Samsung for about 3 months now and it is a very frustrating experience coming from an iPhone experience.

  7. sooo, i have same issue as #10. I did EVERYTHING. EVEN A FACTORY RESET. and it still keeps saying Authentication Error. only my home network is unable, and everything else connects to the network just fine. if you have any ideas what i should try, that would be amazingly helpful.

  8. I also have a samsung s6 phone. It was working fine but after downloading system update yesterday I have no wifi. Even with the wifi button is on the phone say wifi disconnected. I tired holding the volume and power button to reset the phone there is still no wifi connection. Do u know why?

  9. So my S6 has been restarting recently this past 3 days. At first I thought it was because my battery ran out so it restarted nonstop till I plugged it on the charger. It was normal until it did it again the following night. I was using my phone when it suddenly restarted numerous times again to the point that it won’t even make it to home screen. It keeps on restarting and restarting until I charge it again. The next day it happened while I was using social apps on my phone. Then I realized, it kept on restarting when the wifi is on. So I turned it off. I can use it normally without it restarting. However, when I turn the wifi on or open my data, the same thing happens again. It won’t stop restarting until I charge it.

    The main problem is, I can’t use either the wifi or my data without charging my phone. Otherwise, if it is not connected to the charger, it will keep on restarting even though it doesn’t have low battery. What do I do? Please help. Thank you.

  10. I have a samsung a7 2016 and wifi is not turning on and the mobile hotspot is not too previously the Bluetooth stoped working but it’s now working but the wifi and hotspot aren’t can you help me please !

  11. Hi Guys,

    I am having the same issue as CL on the tread posted on Problem #7.

    Your suggestion is to look into the wifi connection. I think this is not the issue, especially on my case. I think it is the samsung device. At my place there were 1 laptop, 5 phones (4 of them Iphones and mine the sole Samsung)), all other devices can connect to wifi without an issue – can do streaming, browse facebook, youtube. You name it they can do it. I am subscribed to a high bandwidth plan with my provider so it is really not an issue.

    Since I started downloading this upgrade to android 7, everything went bad. As CL encountered as well, connecting to LTE works fine but when connecting to WiFi it is soooooooo slooow to the point you want to throw your phone to the wall especially when other people at come can enjoy what they are browsing / streaming on their phone.

    In terms of WiFi congestion – even if I am the only one connected to WiFi still the same slowness.

    Things I have done:

    1. Reset my router – benefit of the doubt
    2. Assign a static IP from my router to my phone – didn’t help
    3. Played with DNS on advanced settings – didn’t help
    4. Did factory reset on my phone – hoping it go back to android 6 but no, it is still with android 7 and yep didn’t help

    Any thing else you can suggest?

  12. Every time my son comes home and his phone connects to the computer wifi the internet crashes and we lose connection. When the internet is back up and running he finds that his wifi connection keeps dropping out. Any suggestions please.

  13. So I updated my Galaxy by accident ,and now the Wi-Fi does not work on my phone. I know it’s my phone because everyone else’s phone in the house works perfectly good on Wi-Fi ,due to the upgrade or update my Wi-Fi no longer works on my phone. Is there anyway I can go back to take the update off so my phone can go back to normal and I can go back to using my Wi-Fi

  14. My s6 will not connect to my home wifi after the most recent phone update. There are five other phones and other laptops that are connected so my home wifi must be fine. Please help.

    Thank you,

  15. Kindly: the ‘fixes’ offered in these Q&A’s are great for all 101 Readers, but anyone looking for a thorough explanation solution to their problem [Not steps on how to do reinstalls, cache clears, restarting device, factory reset] will find themselves disappointed 97% of their time spent on this page.
    GREAT for all Android newbies and 101 users!!! 🙂

  16. You call yourself ‘The Droid Guy’. No doubt you fancy yourself as tech-savvy. I think you’re full of shit.

    Your answers on here are a joke – they mainly consist of Microsoft-like, generic, proforma answers. All you seem capable of doing is stating the obvious trouble-shooting steps (which most users would’ve already tried), and then suggesting a factory reset. How pathetic.

  17. The answer to problem #7 is: your work wifi network has 802.11r enabled and your phone is too stupid to deal with it. Delete the network from the wifi network list by long-clicking on it, then choosing “remove network”. Switch off wifi, then switch it back on. Click on the network and open “advanced settings”. Remove the tick from the “FT” setting, then configure the pre-shared key or your login credentials again. It will probably work now but of course you will not benefit from the 802.11r fast transition feature and your phone will lose connection when you move around while iPhones will not.

  18. Help. I recently got an S6 at a cash for gold place and its got what i like to call “selective wifi connectivity”. The wifi will work for google and social media accounts but on some apps (Jimdo for example) it says my wifi connection is non existant. Ive tried resetting the phone many times, turning it off and on and ive resorted to turning the wifi modem on and off more times then i care to admit. Im running out of ideas.. is anyone else having a similar issue? Does anyone know how i could fix this nonsense?.

    Thank you.

  19. I just performed a (#10) soft reset after my wifi connection kept continuously going off and on.

    Thank you for the great and easy to understand information.

  20. Hi. I have a Samsung galaxy s6 edge. This problem recently started happening. When I connect to wifi, all my apps seem to work great (facebook, instagram, etc.) but, when I type something into google search it will bring up the page with the search results but when I click on one of the links to open the page it always ends up giving me an error connection page. All of my other devices connect to my home wifi without any problems at all. I’ve forgotten the network on the phone, powered it off/on, changed my wifi password and nothing seems to work. I don’t understand why all of my other apps work when the phones connected but when I try to visit any webpage on the internet it won’t load. It also occurs when I’m connected to other wifi networks too.

  21. I tried that and IT STILL DOES IT. I saw this on youtube. And it doesn’t seem to work. My phone just turns it off even while I’m actively using the browser.

  22. Please help! I have a Galaxy S6 Active and it drops wifi all the time. Once it drops a wifi network, by saying it fails to obtain the IP address, it will not connect to any other wifi networks, such as my house, school, and work wifi etc. I have to restart my phone in order for it to connect again and I am getting fed up with it. The phone has been doing this for about 5 months now, any suggestions as to how I can fix the problem??

  23. Here is a possible explanation, even if it is a bit late as you already have a new phone….

    It might be related to what kind of radio signal each of those wireless networks SSID (Service set identification) belong to. First you have to make sure that your phone is set to listen to both frequencies (dual band: 5 GHz and 2.4 GHz) to even be able to see SSIDs in range of your device and there is also the possibility that owner to each missing SSID might have changed SSID to become hidden or given new names since last time your scanned (or searched) your wireless network. In general 5 GHz band is capable of higher bandwidth measured in megabits pr second (Mbits/s), but signal strength tend to go weaker faster from router or sender (range) compared to 2.4 GHz to receiving device.

    It is a bit more complicated then this when one want isolate what could have made your new phone to miss those SSID on your wireless network, but in short you have to look into more then just going from what SSID your old phone could see for wireless and make sure that all SSID actually are active, that your phone is set to work at the same wireless standard (802.11 b/g/n and ac) as those SSID operate and at least that your phone is set to dual frequency for both 5 GHz and 2.4 GHz. (Turn off dual band to save power, if you don’t need it.)

  24. Hi I have just got my new Galaxy 6s edge plus, however, I was unable to connect it to my university WIFI. It asks me to enter IDENTITY! is there any way where I can enter ID and Password instead? Thanks

  25. Hello! I have a connection problem with my Galaxy S6. I am able to connect to wi-fi everywhere but to work. Every other phones that are not Samsungs are able to connect to this particular wifi, but nobody that has a Samsung can. Why? I’ve tried to reset the router, forget the wifi, restart my phone, etc. But nothing helps. Can you help ? 🙂

  26. Disable phone’s Wi-Fi power saving mode

    1- Go to your phone dialer
    2- Dial *#0011#
    3- Hit Select more (top right)
    4- Next Select Wi-Fi
    5- Turn off Wi-Fi power save mode(enabled by default)
    6- Exit this menu, turn off your Wi-Fi and turn it back on. I hope Wi-Fi connection problem have solved.

  27. Hello,

    I still have connection visible in the status bar, but wepages stop recieving data and it just stays hanging, with the loading bar at the same place.
    One sollution is to toggle data connection on/off, then it will work again. Does anyone knows an permanent sollution for this issue?

  28. I got my edge 6 about a month ago. I have taken it back and traded out for a new because I have had the same issue with the first on as I have this one. I work for a company that has Wi-Fi every where. But my phone will not show me all the wi-fi options. I have been using two different phones so u have wi-fi at all times. Because my other phone actually gives me all my options. Like example. Wi-fi networks available on my new edge 6 : (supposed to be wifi names)
    Wifi networks available on my old phone:
    Jerry shows up on my old phone as an option as to where my brand new phone it doesn’t. I have already replaced it and its the same with both phones. My parents have the same phone, company, plan and contract as me, beings I am on their contract, theirs works and mine does not. Why?
