Galaxy S4 Asks For WiFi Password Every Time, WiFi Turns Itself Off Automatically

gs4-wifi-settings

This post will answer questions or address problems related to Samsung Galaxy S4 WiFi connectivity. While only one email message will be shown here, we have already received tons of questions related to it. Here is the actual email from one of our readers:

I have internet service through my home phone AT&T. I have a wireless modem. I have to enter my password every time I leave my home and return.  The phone detects the modem but I am required to enter the password. Why doesn’t the Galaxy S4 remember/save the password? Is there a setting to fix this? 

Another issue is my WiFi will be off and I have not turned it off. If I’m in an area that does not have WiFi, is there a setting that causes the WiFi to turn off?”

Basically, there are two problems here:

  1. Galaxy S4 always asks for WiFi network password every time the owner tries to connect.
  2. The WiFi automatically turns itself off. (The owner didn’t specify whether the disconnection problem happens while the phone was in use or not.)

Why doesn’t the Galaxy S4 remember/save the password? Is there a setting to fix this?

Yes, there is a fix to it. It’s actually just a matter of ticking a checkbox so the device would automatically connect to a trusted / saved network. Here’s how to do it:

  1. From the Home screen, tap the Menu key.
  2. Tap Settings then touch the Connections tab.
  3. Tap WiFi, then tap the Menu key again.
  4. Touch Advanced.
  5. Tick the option Auto Connect.

The Auto Connect option allows your device to automatically connect to a saved network whenever the phone is within range.

Another issue is my WiFi will be off and I have not turned it off.

Due to the power-saving features of the Galaxy S4, WiFi will be turned off the moment the phone goes to sleep or becomes idle for several minutes. But you can set the device to continue connecting to the network while other processes are being stopped. Here’s how…

  1. From the Home screen, tap the Menu key.
  2. Tap Settings then touch the Connections tab.
  3. Tap WiFi, then tap the Menu key again.
  4. Touch Advanced.
  5. Tap the option Keep WiFi On During Sleep.
  6. Tick Always.

This is just one angle of solving the problem. Let’s try to look at it from another angle; this time, let’s dwell on the network problem.

Modems and routers needed to be refreshed from time to time. When is the last time you power-cycled your modem? If you can’t remember when, then today may be the best time to do it.

  1. Unplug your modem (then the router if you have one).
  2. Let it rest for a minute.
  3. Plug your modem again (it may take 30 seconds or a minute before the modem can boot up).
  4. In your phone, go to WiFi settings and forget your network.
  5. Let the phone detect your network again and connect.

  1. I also have a an S4 which has developed this loss of WiFI password memory issue and have tried all these fixes listed and more and even updated my Android software to the latest version. Then was going to give up. I left the house manually joined another Wifi network and when I returned to my house to my amazement it auto connected. I tested this by turning off the router, it rejoined, then I powered off my device and it also rejoined but then later it lost connection and when i checked my router in the WiFI listings it was not showing my router was connected and was showing blank password. I left it overnight and next day I found it was actually connected to the internet via WiFi even though the WiFi list shows no router ‘connected’ and yes i always have mobile data switched off. teh WiFi beams and arrowas are sactive in and out and i can access all i want but my router in the WiFI list just says ‘Secured WPS available’ when i would expect to see ‘Connected’ How weird is that?

  2. The only other option I would suggest is to go to Sam mobile web site download your latest firmware for your phone and carrier factory reset your phone then using a PC and Odin software flash the firmware to your phone and hopefully any glitches you have should clear them, YouTube search how to flash galaxy s4 firmware using Odin if your unsure how to do it I’m sure they will be tutorials on there of how to do it. Good luck mate, Google is your friend 🙂

  3. i really appreciate your concern! 🙂

    unfortunately, i’ve done it before i asked for help here.. my phone refuses to remember passwords and preferences (if i tap a link or a picture, it will always ask how i want to open it, regardless if i tap ‘always’).

    i rebooted the phone last week and upgraded the version, still the same.

  4. Just a thought make sure your wifi advanced settings are to keep WiFi on when your phone screen is off. Check these settings..select WiFi Settings
    Here make sure that the slider next to the Wi-Fi option shows ON
    Tap Wi-Fi
    Tap the Menu key then select Advanced
    Tap Keep Wi-Fi on during sleep
    On the pop up menu select Always. When the dot indicator shows green means this option is selected.
    Now the phone’s Wi-Fi will remain connected to the Wi-Fi network even if your phone is asleep hope that makes sense 🙂

  5. unfortunately, my phone requires restarts – gets slow and laggy after a day or two.

    soon as i click the app, nothing happens.. it won’t connect.

    i’m on lollipop, so i’ll try to update, not sure if my phone can handle it.. maybe that’s my que to let it go.

    thank you so much 🙂

  6. Lol I never turn my phone off so haven’t come across that problem. Soon as you click on the app your WiFi will connect again. See if there’s any firmware updates for the phone. My phone’s a galaxy s5 btw but I feel your pain as I’ve been there before, my phone’s rooted and I’m on Android marshmallow firmware now with no problems thank god, if I come across any other fix I’ll let you know.

  7. hi, tnx for the quick response 🙂
    did as you said, the app now remembers my password, but won’t auto-connect after restart.. so that doesn’t help too 🙁

    honestly, that is the most ridiculous situation i’ve ever had.. my phone abuses me xD

  8. Try the Neverforget WiFi app from the playstore that definitely worked for me.. Just make sure when your entering your WiFi name that it is exactly the same as your WiFi connection (its uppercase lowercase sensitive) obviously entering your WiFi password after. Hope that helps.

  9. sooooo..

    i followed the instruction above, nothing changed.
    also tried Buckoroo’s solution, didn’t work.

    any other idea?

  10. No problem glad it helped you, I think I found this solution of xda site after weeks of trawling through the forums, I fixed mine through my rooted phone, had to change some setting permissions in one of the system files. But the app used to work just fine.

  11. Boo ya boo ya. I’ve had this problem for 5 months and finally Buckoroo’s solution has fixed it for me. Many thanks!

  12. Looks like I will have to do a reset on my phone. Boo! Thank you for your recommendations and assistance. Cheers!

  13. Here’s a solution that worked for me. Once your connect to your WiFi, go back into your WiFi selection(list) hold your finger down on your WiFi and click “modify network config” re-enter your wifi password and then click save, and it should save it permanently. It worked for me. And it wouldn’t work previously. Hopefully this has helped anyone with this problem.

  14. Hi Liz use the Neverforget Wifi Autoconnect App from the google play store hope this helps you as it did me 🙂 otherwise I think you have to do a factory reset of your phone.

  15. Hi Liz the easiest way is to install the Neverforget WiFi – Auto connect app from the Google play store heres the link

    https://play.google.com/store/apps/details?id=nu.auto.wifi

    My phone is rooted so I changed some permissions, but this app worked for me, open app switch it on at the top right go to add WiFi, you just need to remember your WiFi name and add your password once add manually. 🙂

  16. Hello, I have a Galaxy S4. I have internet service and wireless modem through my home phone, with AT&T. Lately, I have to enter my password every 5-10 mins. It shows my wireless network name, but I have to re-enter the password. I have turned on and off my modem, turned on and off my phone to re-enter the info and I am still having issues. Also for some reason, in the advanced tab, under auto configure, the connect tab is not highlighted for me to connect. I have to click “Non in order to connect which then I have to re-enter my passcode again. I never had any issues prior to this, except the past couple of weeks. Is there a setting to fix this? Any advice or recommendations, would be greatly appreciated. Many thanks!

  18. Would it be possible to update this for Lollipop as this seems to have disappeared the solution.

  19. I have the same problem with a Note Edge. The settings are OK but the WIFI connection and disconnection is still erratic; happens automatically sometimes and other times demanding to connect manually. Its really eating into my data because I may not notice fast enough that the WIFI has dropped and I am using data service. Really frustrating after migrating from iPhone. Would like to hear if anyone has cracked it.

  20. Several months ago you commented on
    a post I made, A follow up! I had a catastrophic failure of my DSL Modem which took out the Wi-Fi,
    The repair man installed a new modem and I the problem has gone away, the phone
    signs in automatically every time I enter the house, I fact it signed in at the
    end of my driveway a good 100 yards from the modem.

  22. I haven’t done anything to my phone since my post of 12 days ago, today I have gone out and each time I returned the phone connected by itself. It’s done this before it will auto connect for a day or so and then just decide on it’s own that I need to enter the password. I’ll try what you suggest.

  23. I fixed mine last night. Auto connect is deselected on my phone, so Auto connect is not a factor in this problem. I changed two variables, but the solution may be just one of the items I changed. I manually typed the name of my Wi-Fi network instead of selecting it from the scanned list. While viewing the scanned list of networks, press the menu button, and select Advanced. Turn off the option for “Check for Internet service”, with the subtitle “Auto switch between Wi-Fi networks and mobile networks.”

  24. Followed the instructions here to the letter and I still have to reenter my password every time that I return home. Starting to think that the S4 is a pile of crap!

  25. I also have all of my options set correctly and I still have to manually connect to my wifi at home at at work. It doesn’t remember any wifi spots or passwords. I’ve tried using the AT&T smart wifi app and it is no better.

  26. …and now how do you fix this when those options were already in place? My WiFi drops in front of my eyes whether I’m at home or at work, and I have to re-enter my password EVERY TIME. It’s already set to automatically connect and to keep the WiFi on during sleep. It’s incredibly frustrating.

  27. hello , i have a problem with wifi on my galaxy s4 I have a wireless modem. I have to enter my password every time I leave my home and return. The phone detects the modem but I am required to enter the password. i tried the above fix which you have posted but yet its the same .. could you please suggest some other fix
