How To Fix Galaxy Note 2 Internet Connection Problems

Written By PhilBlogger on Saturday, February 23, 2013 | 4:43 PM



We got three problems from users of Galaxy Note 2 here. The first one is about not being able to connect to a mobile data network, the second is about Wi-Fi connection problem. The third one is a lot easier as it concerns how to keep Wi-Fi connection stable even if the Galaxy Note 2 is left to become idle.


Problem 1: My Galaxy Note 2 cannot connect to the Internet using 3G/4G but it can connect via Wi-Fi. I don’t know what the problem is and I sure need your help to fix this. I’m not at home most of the times so I need to connect to any mobile network every time I check my email.

Solution: IP-capable devices such as smartphones and tablets that also has a capability to connect via a mobile network will automatically choose a network that issued the SIM card. However, there is a setting in the Samsung Galaxy Note 2 that offers manual selection. Try to go to Settings => More Settings => Mobile Networks => enable it. Then continue to Network Operators and choose Select Automatically option. If the problem is here, then you can now connect to a network.

Now, check APNs in your device to see if they’re correct. Go to Settings => Wireless and Network => Mobile Networks => Access Point Names. If you don’t know the correct settings, I suggest you call Verizon and ask about it.

There are three things you should check if you have problems connecting with mobile data networks:
  1. Check if your phone is receiving a good signal.
  2. Check if your device is connected to the right network operator.
  3. Check if you have correct APN.
Problem 2: My phone can detect Wi-Fi networks and I’ve been connecting to this network for quite some time until recently. The signal is good and it is my own network at home. Called Verizon several times but they were only willing to troubleshoot connection in my laptop, which is, by the way, also having problems. Can you help me with this? I’m using Galaxy Note 2, by the way.

Solution: Well, we cannot force Verizon’s representatives if they wouldn’t provide support for your phone; it may be out of their support and don’t have the right tools to help you. In part, I would agree with the representative. It is easier to troubleshoot internet problems using laptops and computers than on mobile devices. I hope you can see the logic of the rep: if you can connect using your laptop to your Wi-Fi, then you could also connect with your phone. I recommend you do the following:

Troubleshooting Internet Connection
  1. Unplug your modem.
  2. Unplug your router (if you have any).
  3. Plug your modem and wait for the lights to become stable.
  4. Plug your router.
  5. Using your laptop, click on the “Networks” icon on the lower right corner of the screen.
  6. Disconnect from the network you’re currently connected with. Then reconnect.
See if your laptop can now browse the net. If so, do the following in your phone:

Troubleshooting Galaxy Note 2 WiFi 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.
That should do it.

Problem 3: I can connect to Wi-Fi alright but from time to time, I get kicked out. My connection gets cut off almost every time I lock my device. I often download stuffs, some of them are really huge, so I don’t have time to wait all day for them to finish. So, oftentimes I leave my phone on top of the table while it is downloading something only to find out I have to download again because my connection was cut off. Any suggestions would surely be appreciated. Thanks.

The Samsung Galaxy Note 2 will automatically disconnects from any Wi-Fi network it is connected with when it becomes idle and goes to sleep. However, there is an option so it would continue getting a connection from the network even if it’s idle. Follow the steps below:
  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.
  6. Now, go back to WiFi settings and tap on Menu.
  7. Choose Advanced.
  8. Touch Keep WiFi on during sleep.
  9. Check Always.
These are among the most common problems we receive daily. These aren’t really serious problems they’re just annoying if they happen during the time when you needed to use your internet.

  1. I have to disagree about the comment, "I hope you can see the logic of the rep: if you can connect using your laptop to your Wi-Fi, then you could also connect with your phone."

    Android 4.1.0 - 4.2.0 have issues connecting to networks employing AES encryption protocol. If your AP broadcasts in Draft-N WPA-AES or WPA2-TKIP/AES or any rotating possibilities in-between that have the chance of using AES, the device often will have authentication issues and either not connect, or disconnect periodically after initial handshaking. It was a bug fixed after the release of 4.2.

    For the people affected, the only option was to either go back to bands b/g or switch to TKIP-only broadcast modes.
