 How to Fix the WIFI Problems for Samsung Galaxy Smartphone

Actually, this WiFi problem is not only occurred on Galaxy smartphone, but also on other cellphone, like the Apple's latest flagship iPhone 5S. (check this good tutorial How to Fix the iPhone 5S Wifi Problems) Why these cellphones fail to connect WIFI? How to tackle with this WIFI issue? Let us find the following solutions.

Make sure your routine performs well

When mobile phones or other digital products connect the WIFI signal successfully, it means this routine performs well.

▪ Make sure the item “Keep Wi-Fi on during sleep” is available

Some say their phone can't receive SNS information in the background or their WIFI connection is automatically turned off after a certain time. It may happen if they mistakenly turn off the "Keep Wi-Fi on during sleep" item in the Advanced Wi-Fi option.

Keep Wi-Fi on during sleep


▪ Reset Router

After making sure the above-mentioned items are normal, you are still unable to connect Wi-Fi. Then you have to find the answer from your router.

It is common that plenty of routers will run into dead circle. They occasionally catch up IP, and build connection, but finally fail to do the connection. Then you’d better try the useful recover way – reset Router. Completely turn off the power of router, then after ten minutes, you can try to reset the router. Most find it is workable.

▪ Check if the Wi-Fi connection is overloading

If too many devices connect the same router, it will put much pressure on the router. It would probably result in an IP conflict. The problem can be solved by setting a static IP for every device connecting the router.

▪ Try to change the authentication type

This authentication type is one appropriate of Router Setting.

If you have never changed the authentication type, it will show auto on the “encryption algorithm” item. To be safe, you’d better choose “WPA2-PSK”.

▪ Upgrade Router Firmware

If you have tried the above methods but fail to reconnect WIFI, it is possible that your cellphone doesn’t compatible with the router. It may work if you upgrade router firmware. Different brands of Router upgrade methods are different. Highly recommend you search the related information from upgrade page or on the Internet at first.

▪ Flash an appropriate ROM

If all the above ways are not workable, it may probably that your Cellphone' ROM is not suitable. You can try to flash an appropriate ROM to tackle with the problem.

Have you experienced any other Wi-Fi issues on Galaxy S4, S3, Note 2, or Note 3? Did the above-mentioned Wi-Fi solutions help you? Let us know your comments below.

    My S3 connects to WiFi but only in the room where the router is installed. when I move out of the room, the Wifi signal goes away, It shows in the available network but cannot connect and it just says “Saved” “Secured” and tries connecting and gives an authentication problem.

    What could be the issue. Could it be battery not having enough power for the antenna. My phone is 5 years old and running on original Samsung replacement for the last two years….

    When using wi-fi turn off Bluetooth and your wifi will work just fine. The resolution to this problem is as simple as that. It appears that the dual-use antenna does not work properly period when Bluetooth is turned on it appears to load down the antenna. Try this and you will be happy the phone will perform as good or better than any other Wi-Fi connection you’ve ever had.

    • BY Paula

      THIS WORKED!!!!!!! Wow Tom – who knew it could be so freaking EASY! for 2 years I’ve been fine with both wifi and bluetooth turned on, but in the past week, I’ve spent at LEAST 6 hours on the internet to find out why my phone stopped connecting to wifi at home . EVERYONE TRY THIS!! JUST TURN OFF BLUETOOTH! thank you SO MUCH Tom!

  11. BY Abdul Saboor Zaheeb

    Hello sir/madam,
    I have SG3 and have been using since two years ago. It was working so far in all Wifi and in my room’s Wifi connection. Todad, in the middle of the day, I realized it does not connect to Internet with the router is working well. It asks me to enter password and as I enter password, it says INCORRECT PASSWORD and then asks again to enter password. First “Saved, secured with WEB” and later “Authentication error occurred” appear right at the bottom of Wifi Network Name. I tried some other ways but did’nt work unfortunately:1(Dialling “*#*#0011# and turning OFF Wifi reset psm) and 2 (Changing IP address from DHCP to Static)

    Got a note 4 yesterday from Verizon. The WIFI worked fine at home for the entire evening. However, this morning, the WIFI was cut off. The WIFI button on the phone was kind of a grey color. Not “on” not “off”. I couldn’t turn the button on. I powered off the phone and turned it back on. It worked – the phone connected to the WIFI.

    This afternoon, I came back from a friend’s house. When I got home, the phone didn’t connect to my home WIFI again. Had to power off and power on again.

    Anyone know how to fix this problem?

  21. BY zzigmond

    Try all the steps above, if they don’t get results remove your back cover and/or protector and get close to your router if it connects easily you antenna is damaged, probably from being dropped like mine :(. I haven’t been able to find a parts breakdown for this phone either.

      I have the same problem. I have a galaxy s4. When I’m at home, I don’t have signal so I use wifi and wifi calling. I get “very strong” wifi signal and can access websites, chat on fb Messenger, and make calls. However the phone will not show pictures. On fb, instagram, and tumblr for example, it just shows a gray box. Occasionally one pic will load. Tried resetting router and phone. The only other thing connected to the router is my xbox, but when it’s off, I still have these issues.

Please help me in this matter.

      You need to tell your phone to forget your home network then allow it to find it again re-entering the password. Turn of mobile data at home too so your phone doesnt keep trying to switch from one to the other.

      I was having same issues all the time with saying unstable wifi, then realized I could not connect thru carrier either.

        If turning off alone does not work, try turning off and removing battery for 30 seconds before replacing battery and restarting. This worked for me without having to master reset my phone.

        Do you have a mobile data plan? I had the same problem, wifi was disconnected due the “poor signal” and phone had switched to the mobile data. Try to uncheck “auto network switch” in advanced wifi settings, I think it works. Now system does say “internet connection is unstable”, but doesn’t disconnect you.
