Note 3 connectivity 2

One of the things that make a Galaxy Note 3 a smart device is undoubtedly its ability to connect us to the web almost flawlessly. This device is packed with an impressive array of wireless technology, giving its users plenty of options to connect to other devices or the internet in general. With this capability comes problems though. It’s not uncommon for many Galaxy Note 3 users to complain about all sorts of connection-related issues. We believe that  by publishing these individual stories and problems, we are helping the burgeoning Android community deal with them effectively.

Our post for today provides solutions for Samsung Galaxy Note 3 Wi-Fi or Mobile Data connectivity problems shared by some of our readers in the past few weeks. If you want to contact us about your own connection problem, don’t forget to use the link provided at the bottom.

 

Problem #1: Galaxy Note 3 cannot connect to Wi-Fi after an update

SAMSUNG GALAXY Note 3 CAN’T CONNECT USING MOBILE DATA and when i go to settings and go to more selections it’s only a VPN. No other selections to turn on my data. I did a factory reset the day all this started taking place. — Janell

Solution: Hi Janell. There must be a third party app restricting the phone to establish a Wi-Fi connection. Please do another round of factory reset but do not install the same set of apps afterwards. Simply run a clean OS version without any other outside apps then attempt to connect via Wi-Fi again. If there’s no problem doing that, you can start installing apps one by one. Make sure to check the Wi-Fi functionality after installing an app to know if it is the reason behind this trouble.

Problem #2: Galaxy Note 3 Wi-Fi connection keeps dropping

I am unable to keep my Wi-Fi online at either of our homes. Our computers have no problem. I have taken it to US CELLULAR 3 times and they say they have no problem with my phone. Yet unless I am practically sitting on top of my network I lose my Wi-Fi connection in the middle of doing things on the internet. My husband’s phone, the Galaxy S5, does not have a problem in either of our homes.

This started when the phone wanted to update itself this spring. I am at a loss as to what to do. It just keeps dropping connection all the time even though I have 3 to 4 bars on my phone. I have also tried that *228 to reset with the towers that US CELLULAR told me to do.  It didn’t help. — Frances

Solution: Hi Frances. Have you tried connecting your phone to other Wi-Fi networks to see any difference in behavior? If your phone works fine in other Wi-Fi networks other than those in your homes, you can narrow down the factors to two things:

  • hardware issue
  • Interference.

Device hardware problem

It’s highly unlikely that both Wi-Fi networks at two different places can cause the same exact problem to only one device, unless the connecting device itself (your Note 3) is at fault. To determine if there’s a possible hardware issue on your phone, you can use the process of elimination in this case. A good way to do that is by performing the normal software troubleshooting like deleting the phone’s cache partition or restoring the phone’s defaults thru factory reset. I would personally recommend that you simply jump to factory reset to ensure that there is no software issue involved. To do that, here are the steps:

  • Turn off your Note 3.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power.
  • When ‘GALAXY Note 3′ appears on the screen, release the Power key but continue to press and hold the Volume Up and Home keys.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight wipe data/factory reset.
  • Press Power button to select.
  • Press the Volume Down key to highlight delete all user data.
  • Press Power button to select and start the master reset. When the master reset is complete, Reboot system now is highlighted.
  • Press the Power key to turn the restart the device.

After resetting the device back to its defaults, that should be a good time to try connecting again to either of your Wi-Fi networks. Make sure not to install any app after doing a factory reset to help you determine as well if third party apps are to blame. If the phone continues to experience the same problem after a factory reset, that’s a clear indicator that there must be a problem with the phone’s wireless adapter. In that case, your best bet would be to ask for a replacement or have the device checked by a qualified technician for a possible repair.

Wi-Fi Interference

Sources of Wi-Fi interference abound. They include, but not limited to, Bluetooth devices, wireless video cameras, microwave ovens, cordless phones, wireless game controllers, WiMax, even your ordinary fluorescent lamp. Some bad electrical connections can sometimes create radio frequency distortions that might affect 802.11 networks like the one being used by your Wi-Fi devices. Unfortunately, it takes the right tools and the right people to track the real source of wireless interference most of the time.

In your case, we don’t think interference is the main reason as other devices appear to work fine. Once there’s a constant source of interference in an area like a portion of your home, other wireless devices should also effectively suffer the same problem, which is not true. While a remote possibility, it may still be a good point to look into if you can’t determine the real source of the problem.

Turn off smart network switch

There have been a few similar cases in the past that were resolved by simply disabling it. To do that, just go to Settings>Wi-Fi>Menu>Advanced.

Problem #3: Galaxy Note 3 loses connection when switching from Wi-Fi to mobile data

Hello. When i move away from a Wi-Fi area and the phone switches to the cellular data network, i lose connectivity. I have to then activate and deactivate airplane mode for it to reconnect to the data network to restore connectivity. For some weird reason the phone does not switch networks properly. Any help would be appreciated. Thanks. — Ewan

Solution: Hi Ewan. Samsung’s smart network switch sometimes fail to do its job, plain and simple. This problem became more apparent after Android Lollipop was released, although other devices running KitKat still suffers from the same glitch. There’s really nothing much that a user can do to fix the problem. You can either simply disable it permanently, or try performing a factory reset. The latter is Samsung’s recommendation when we asked them for a solution before.

Problem #4: How to disable Galaxy Note 3 smart network switch

The mobile data and Wi-Fi turns on  automatically . — Mike

Solution: Hi Mike. Please turn off your phone’s smart network switch under Settings>Wi-Fi>Menu>Advanced.

Problem #5: Galaxy Note 3 stops detecting Wi-Fi networks after updating to Lollipop

Good day.

Since I update my Note 3 SM-N9005, I’m having a big problem connecting or detecting Wi-Fi connection. I follow all the process that I had read in the forums and troubleshooting. I update it first on using phone and after the update it can detect a Wi-Fi and after I restart it cannot detect any Wi-Fi. So I install Kies 3 to my laptop, sync my Note 3 to Kies and another firmware is available I updated it to and after that the same thing happened. I reboot it, wipe cache, factory reset and carefully try to find out what’s the problem in setting but still cannot detect. It happened once that I detect and connect in Wi-Fi but after I go to another Wi-Fi connection it goes back to the same problem again. And now having hard time to find a solution. I am regretting updating my phone to Lollipop.

Hope you can help me. Thank you. — Aldrin

Solution: Hi Aldrin. The phone might have encountered some hardware issues so it’s best if you can have it checked by a qualified technician. While rare, a major upgrade like Lollipop can sometimes result to unforeseen issues.

There’s nothing more that we can do as far as software troubleshooting is concerned as you have done them all.

Problem #6: Hotspot function on Telstra Galaxy Note 3 not working

Hey, I appreciate you taking the time to read this…I have a Galaxy Note 3 with a pre-paid Telstra SIM and it won’t share internet with Hotspot. The Xbox can see the phone but when I try to test the connection it won’t connect to the Internet, it’s the same problem if I try it on a computer, it is recognizing the device but doesn’t seem to have proper data flow between them. I have spent days researching and nothing seems to work…and I know it’s not the Xbox cause my previous phones worked fine with hotspot. — Cameron

Solution: Hi Cameron. Please talk to Telstra support to see if the account you are using (SIM) is allowed to share internet connection in a hotspot setting. Mobile hotspot functionality is often determined by carriers and is considered value added product. In some U.S. carriers, customers must pay extra to have this feature added to their basic subscription.

Problem #7: Verizon Note 3 won’t connect to network on its own after being out of signal for hours

Over the last couple months, whenever I am out of service for multiple hours, my Note 3 won’t reconnect to Verizon service until I reboot it. I know I am well within service range, but until that reboot nothing will reconnect. I’ve even tried enabling and disabling airplane mode, but no luck in remediation.

I would love a remediation without reboot, as some of my time is on the edge of service and it would be nice to have notifications when messages are left.

Thanks! — Dan

Solution: Hi Dan. In theory, an Android device will supposedly connect automatically back to a cellular network after it’s been out of coverage area for some time, although in reality this does not always happen. This is due to a problems coming a few sources like problematic or incompatible third party apps and faulty firmware. We recommend that you try to delete the cache partition and see how it goes. To do that, here are the steps:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power.
  • When ‘GALAXY Note 3′ appears on the screen, let go of the Power key but continue to press and hold the Volume Up and Home keys.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight wipe cache partition.
  • Press the Power key to select and wipe the cache.
  • With reboot system now highlighted, press the Power key to restart the device.
