Galaxy Note8 keeps disconnecting from internet after updating to Android Oreo

There seems to be an increasing number of #GalaxyNote8 users reporting internet issues after updating to Android Oreo lately. To help those with internet connection issues on their device, we’ve come up with yet another post for them. We also cover other related connectivity issues for this device so read on.

Problem #1: Galaxy Note8 internet connection keeps dropping after updating to Oreo

Hey! I have a couple of issues with my Note 8 after updating it to Oreo. Some bugs here and there, but the biggest one that I started noticing is that the phone can’t keep a steady internet connection. No matter if I’m on wi fi or datas. You can clearly see this when you’re trying to play a game that requires internet connection or for ex in FB messenger where you constantly have “Connecting” or something like that. Do you have any ideas? Raisa.asiar

Solution: Hi Raisa.asiar. If your Note8’s internet connectivity was working before you installed an Oreo update, there are three things that you can try to fix it.

Clear the cache partition

The first possible solution that you should try is clearing your device’s cache partition. This is an often effective step in dealing with issues immediately after an update. Sometimes, the system cache stored in the cache partition, which is used by Android to load apps efficiently, may become problematic. To check if you have a system cache issue, here are the steps to clear the cache partition:

  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 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 to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Reset network settings

Sometimes, resetting your device’s settings fixes network troubles so make sure that you don’t skip it. Here’s how to do it:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap RESET SETTINGS button.

After you reset network settings, you’ll have to enter your wifi password again. If you have Bluetooth devices connected, you’ll also need to re-pair them afterwards.

Factory reset

If your Note8 continues to disconnect internet connection at this time, you should wipe it and return its software settings back to their defaults. Here’s how:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Problem #2: Galaxy Note8 wifi won’t connect, static IP works but no internet

Hello. I am encountering wifi connection problems at home with my Samsung Note8. My laptop and other phones can successfully connect to my home wifi. When I connect my data plan, everything works well (but I don’t want to spend all of my data). When my IP settings is DHCP, I get the error message “AP currently not in use”. When I change my IP settings to Static and enter my IP address, I am able to connect to my wifi but I get the error message “This site can’t be reached” (ie. nothing works even though I’m supposed to be connected to wifi). Can you help me resolving this issue? — Lucie

Solution: Hi Lucie. The issue is most probably caused by a network bug so be sure to soft reset your Note8 first and see how it works. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Also, allow up to 90 seconds for the reset to complete.

If restarting your Note8 won’t help, be sure to clear its network settings (steps provided above). In many cases similar cases, these two should help. If nothing works though, consider troubleshooting your router as well for a possible issue with said device. If you don’t know how to troubleshoot the router, contact your Internet Service Provider.

Problem #3: Galaxy Note8 won’t connect to wifi that uses portal to log in

I have an issue when trying to sign in to my work’s free wifi that started about a week ago.  My Note8 is able to find and connect to the wifi, but when the “sign in” screen pops up is where my issue is.  I go to check the box to agree to the terms and conditions, but when i hit the “connect” button it only unchecks the box and doesn’t sign me in like it used to.  I don’t think it’s the wifi’s fault because I had my friend (who also has a Note8) sign in and it worked for him no problem. This tells me it’s something wrong with my phone  in particular. I have tried a lot of things to try and fix this such as: trying to sign in through the browser, trying to sign in on a different browser, network reset, clearing various caches and forcing different programs to stop, restarting my phone, and nothing has made a difference.  I know I cannot be the first person this has happened to. Please tell me you know of a fix for this short of a factory reset. — Scott

Solution: Hi Scott. This issue often occurs when trying to connect to a wifi network that asks users to log in to their portal first. Normally, forgetting the network and/or clearing a device’s network settings is enough to fix it but if you’ve already tried them, then consider booting your device to safe mode and see if that will make a difference. Here’s how:

  1. Turn the device 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.
  8. Let your Note8 run in this mode for several hours and check for the problem.

Safe mode blocks third party apps and services. If you’ll be able to connect to the wifi network you’re having an issue with, that means one of your apps is to blame. To know which app is causing a problem, follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Note8 still refuses to power back on, repeat steps 1-4.

Problem #4: Galaxy Note8 redirected to Google instead of the wifi sign in page or portal

Hi, I’m not sure if you’re familiar with Xfinity wifi or connecting to public wifi’s in stores. For example, if I’m at a Starbucks and want to connect to their public wifi,  I will select that wifi under settings, and then be redirected to a page where I’ll have to accept the terms and conditions, and then I will be connected. What’s happening is instead of being redirected to the sign-in page, i am redirected to Google, which then doesn’t open. Then the wifi does not work, saying that a sign in is required. — Hadassa

Solution: Hi Hadassa. Try clearing your web browser’s data and before attempting to connect to a public wifi again. To do that, follow these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap More settings (three-dot icon) at the upper-right.
  4. Tap Show system apps.
  5. Find the web browser app you’re using to sign in and tap it.
  6. Tap Storage.
  7. Tap CLEAR DATA button.
  8. Restart your S9.
  9. Connect to that wifi network again.

If clearing your device’s web browser data won’t work, do a network reset (steps provided above).

The most likely issue is your web browser so if the one you’re using right now continues to allow you load the wifi sign in page, you can also set another default web browser like Google Chrome so the next time you sign in, that browser will load instead of the problematic one.
