Note 4 Not Connecting To Wi-Fi Network

Problem: I got my note 4 about 2 weeks ago. Everything was fine and then one day I can’t connect to my work network. Neither the open or the secured work networks. I get “authentication error occured.”How is that possible when trying to connect to an open network. My phone connects to other networks away from work. Other devices are able to connect to my work network. But my phone won’t connect to the work network. Truly frustrating. I’ve tried just about everything under the sun.


  • Forgetting the network
  • Changing the IP address
  • Changing my work login info
  • Trying to connect in Safe Mode
  • Factory reset


The list goes on. Still doesn’t work. Help please!!!!!!

Solution: A factory reset is the last option that should work in most issues such as this. Unfortunately, in this case it failed to resolve the issue. What you need to do right now is to check if your phone can indeed connect to a Wi-Fi source. Do you have a Wi-Fi network at your home? If you have then try connecting to it. You can also try connecting to other Wi-Fi connections from other establishments. If your phone can’t connect to any Wi-Fi network then this issue could already be hardware related. If this is the case then you need to have your phone checked at an authorized service center.

If you are able to connect to your home Wi-Fi network then you should try manually connecting to your work Wi-Fi network.

  • From a Home screen, tap Apps
  • From the Apps tab, tap Settings.
  • Tap Wi-Fi.
  • Make sure the Wi-Fi switch  is turned on then tap Add Wi-Fi Network
  • From the Network SSID field, enter the appropriate name
  • From the Security field, tap the Dropdown menu
  • Tap one of the following security options: None, WEP, WPA/WPA2 PSK/FT PSK, 802.1x EAP
  • From the Password field, enter the appropriate password.
  • Ensure additional settings (e.g., EAP method, Phase 2 authentication, CA certificate, etc.) are set up appropriately then tap Save.

Note 4 Connected To Wi-Fi But No Internet

Problem: The trouble I am having is only with a very few ssid’s. I will be at a hotel, for example, and switch on my wifi and let it scan. I will see the ssid I need and select it. A screen will appear asking for a password. I put in the password and it connects. A line will pop up saying it is getting an IP address (I may have those out of order). I then get a message that although I am connected to the wifi, I may not have connection to the internet, and would I like to continue that way. I touch yes and true to the statement, I have no internet connectivity at all. My Note 4 will not see the internet. It does not seem to be a wifi issue because my laptop connects and works just fine.

Solution: If your other devices can connect to the Wi-Fi network but your phone can’t then there’s a possibility that the problem lies on the phone side. What you need to do in this scenario is to restart your phone. Once this is done open your Wi-Fi settings then forget the Wi-Fi network you are having a problem connecting to. This will delete the connection from your phone. Scan for the connection again and connect to it. If you are asked to enter a password make sure to input the correct one.

If you are still experiencing the same issue then try to start your phone in recovery mode then wipe its cache partition. This will delete the temporary data stored in your phone which if corrupted can cause this problem. Once this is done restart your phone then repeat the same procedure above when you connect to the Wi-Fi network.

In case the above troubleshooting steps fail then you should consider backing up your phone data then doing a factory reset.

Note 4 Dropping Wi-Fi Connection

Problem: I accidentally hit forget when I had my usual WIFI location (at my house) up on my screen.  I have put in the password multiple times and it eventually does connect to my WIFI, but it usually drops it, whereas it never dropped the connection before.  Really nothing else has changed.  I have just been having issues with this since I hit forget.  Please help!

Solution: When you forget a network it shouldn’t cause the connection to drop when you connect to it again. This issue that you are having may be caused by other factors . The first thing that you should do is to restart your phone and router ( if you have a separate modem then restart it as well). Make sure to follow the correct procedure when restarting the modem and router. Turn off both the router and modem then turn on the modem first. Once the modem has fully initialized turn on the router.

Once you have restarted all the equipment try to check if the connection still drops.

If it does then I suggest you try to wipe the cache partition of your phone from the recovery menu. This is to eliminate the temporary data stored in your device which could be causing this problem.

Note 4 Drops Wi-Fi Connection

Problem: Phone drops my wifi and the only way to get it back is to restart my phone this happens at least 2 time per day

Solution: If restarting the phone resolves the issue temporarily then this could be caused by some form of corrupt data in your device. Try to wipe the cache partition of your phone from the recovery mode then check if the issue still occurs.

If it does then restart your router. On your phone forget the Wi-Fi network then scan for it again and connect to it.

If the issue persists try to check if a third party app you downloaded is causing the problem by starting your phone in Safe Mode. In this mode only the pre-installed apps are allowed to run while apps you downloaded are disabled. Check if the Wi-Fi connection drops in this mode. If it doesn’t then you may have installed an app that is causing this problem. Find out what app this is and uninstall it.

In case the above troubleshooting steps fail you should proceed with backing up your phone data then do a factory reset.

Note 4 Error when Connecting to The Internet Without Wi-Fi

Problem: I was reading your article on connecting your phone to the Internet without WiFi using LTE. My phone doesn’t have LTE and only has the options GSM or WCDMA or both (auto connect). I have tried both but am receiving an error when I try to use the Internet without WiFi. And my wifi is off when i do this. How can I fix this?

Solution: There’s a possibility that your phone is not using the correct APN settings. Since you are using the T-Mobile network try to check if your phone is using the settings listed below. Make the necessary changes in your phone if needed.

  • Name: T-MOBILE
  • APN:  but if it’s an LTE Device, use: instead
  • Proxy: <Leave in Blank>
  • Port: <Leave in Blank>
  • Username: <Leave in Blank>
  • Password: <Leave in Blank>
  • Server: <Leave in Blank>
  • MMSC:
  • MMS proxy: <Leave in Blank>
  • MMS port: <Leave in Blank>
  • MCC: 310
  • MNC: 260
  • Authentication type: <Leave in Blank>
  • APN type: default,supl,mms
  • APN Protocol: Leave it to the Default one

Remember, even if you have the correct settings you will still need to have an active mobile data subscription from your carrier.

Note 4 Not Getting Good Data Reception

Problem: I just switched phone companies from At&t to Metro PCS. I own my galaxy note 4 but Metro offered a new phone and I used it for a week and had a much better signal. Two bars and connected to internet much better too better than At&T  but when I switched back to my note 4 same issues started, bad reception again. In conclusion, it is my phone that doesn’t get good reception.

Solution: What you can do in this case is to backup your phone data then do a factory reset. Once the reset is complete check if your phone is getting a good Internet connection from your carrier. If the issue still occurs then this could be a problem with the phone firmware since it was originally intended to work on the AT&T network or it could be  hardware related problem. I suggest you have your phone checked at an authorized service center.
