How to troubleshoot Galaxy Note 8 that won’t connect to wifi

Being unable to connect to a wifi network can be caused by a number of factors so the steps below should assist you in determining what the problem really is. Just be sure to the things in the order we provide here so your troubleshooting will be logical.

Solution #1: Do a complete network device and phone powercycle

Before you embark on doing advanced device troubleshooting, make sure that you do the basics first. One of such basic things is by doing a powercycle, commonly known as restart. For this job though, you do not want to only restart your Note 8 but also the networking gadgets like modem and router (if you have two separate devices). If you only have a modem/router combo device, then make sure that you unplug it from its power outlet for at least 30 seconds. This will help clear its memory and refresh its system. After unplugging your router, make sure that you turn your Note 8 off as well. Then, once the 30 second threshold for each device has passed, turn the devices on sequentially: modem/router first, then your Note 8. Be sure to let the modem/ router initialize properly first before attempting to turn on your Note 8 to allow the router’s system to come online before a device connects to it.

Solution #2: Verify wifi is working

This is not exactly a solution but a way to help you identify where the problem lies. If your Note 8 still fails to connect to wifi, or if it’s connected to the router but internet is still not working, make sure to check if other wireless devices work fine. It’s possible that there may be an internet or router issue so using another device to check is a must. If you don’t have another phone to use, try to connect a laptop to your wifi and see if it connects to the internet fine. If it does, continue troubleshooting your Note 8. If it’s otherwise, which means a second device won’t be able to connect to the internet via your home wifi network, then that’s a clear case of a router or internet-side problem. Contact your internet service provider to help you fix the trouble.

Solution #3: Forget wifi network

If faced with a wifi problem that occurs all of a sudden, it’s always a good idea to simply disconnect from the network, wait for a wait seconds, then reconnect. This not only breaks or eliminates possible bug but it’s also a good way to know if there’s an authentication error that prevents your device from accessing wifi services. This step is especially helpful when you’re having trouble with a wifi network you don’t have control over, like a public wifi.

Disconnecting or forgetting a wifi network is simple. Just pull down the notification bar, press and hold the wifi icon, tap the wifi network you’re having a problem with, then hit FORGET.

You can also go under Settings>Connections>Wifi to achieve the same goal.

Some users may set their wifi connections manually by using Static under IP settings. If you are too, try switching back to DHCP and see if that will help. To do that, you can do the following steps:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Wifi.
  4. Press and hold the network you’re connected to then tap Manage network settings.

Solution #4: Connect to another wifi network

Sometimes, an Android device may be able to connect to other wifi networks but not in others. In this case, you want to see if your phone has a problem connecting to any wifi network so make sure to go out there and see if it does. Try going to a friend’s house and check if your Note 8 can connect to their network just fine. Do this for at least 2 more wifi networks to be sure.

If your phone can connect to other wifi networks without problems, then the issue must be with your router settings, or how it’s setup. If you’re not the wifi administrator, make sure to let the one in charge know that your Note 8 is having trouble connecting. There may be a special filtering or blocking system in place that prevents your Note 8 from using the internet via that router.

Solution #5: Boot to safe mode

Is it possible that an app can block wifi connection in your Note 8? Definitely! Any poorly built app can cause problems so anything can really happen. Fortunately, you have an Android device so checking for a possible third party app is very easy. Here’s how:

  1. Turn the Note 8 off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

Now that your Note 8 is running on safe mode, connect to your wifi again and see how it works. If internet works normally when in safe mode only, that’s a clear sign that one of your apps is problematic. To fix the problem, you must uninstall apps until you’ve eliminated the source of the bug from the system.

Solution #6: Install updates

Updates not only add improvements and cosmetic changes but also fixes known bugs. Needless to say, updates are necessary to maintain and secure your device. It’s also a recommended step even if you don’t encounter any issues.

Solution #7: Factory reset

Should the issue remain at this point, don’t hesitate to invest time and effort in wiping your device and starting from scratch again. With this issue, there’s no clear cut way to directly identify the cause so doing a broad sweep will most likely help. Because factory reset will revert all software and app settings to their defaults, it’s wise to back data that you can’t afford to lose first. Once that’s taken care of, do the following steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe data / factory reset.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.
