How to Solve AT&T Galaxy S3 Internet Problems


This post deals with AT&T Galaxy S3 Internet Problems including 3G, 4G and Wi-Fi issues. Solutions, recommendations and workarounds presented in this post are all based on expert opinions and reports from users who have experienced these problems but were able to fix them. AT&T Galaxy S3 is stable but it is not free from errors and problems.

It is never a surprise to hear people complaining about not having been able to connect to the internet using their smartphones. Common as it can be, this problem was haunting AT&T Galaxy S3 users, too. Many users, however, reported to have experienced the problem after the Jelly Bean update. It could be software-related but it could be another thing. The point is users have to do some steps to determine where this problem came from aside from the common suspect—the recent software update.

If you are using mobile data (3G or 4G) to connect to the internet, try to check the signal reception of your phone first. More often, poor signal reception is the cause why you cannot connect to the internet or experience very slow browsing. Try to find spots where you can get good signal and try to connect. If you could, then the signal reception is the culprit.

Secondly, try to check the settings. Carriers have their own APNs and settings, if you don’t know yours, try calling AT&T and ask for it. Settings can easily be messed up so there’s a possibility that problem lies in there.

For users who are using Wi-Fi to connect to the internet, it is advisable to refresh the connection:

Refresh Galaxy S3 Wi-Fi Connection
  1. Go to Settings and choose Wi-Fi.
  2. Tap on the network you often connect, then tap on “Forget This Network” button.
  3. Turn off Wi-Fi, then turn it on after a couple of minutes.
  4. Let the device detect a network and try to connect.
  5. See if you can now connect to the internet.
There are times when the Wi-Fi configuration gets messed up or corrupt. Forgetting the network means deleting all of its settings so the device could detect it as a new network. The settings will then be newer and fresher the next time it will be detected by the device.
If the problem persists, try rebooting your device and when it continues to bug you after that, it could be the perfect time to do a Factory Reset, although you’ll have to take some time to back up every important data in your phone including your SMS messages, contacts, etc…

You don’t actually need some complicated troubleshooting steps to resolve these problems. More often, refreshing settings and data would solve issues you’ve never experience before.
