4G LTE data is overriding my WiFi

Hi zeplans,

I apologize you're having these issues with your Note. I have saw this before in a few devices. Some things to look at:

• Remove any apps that control data or WiFi
• Remove any newly installed apps.
• Remove the battery and and SIM card for about 5 minutes and then reinsert and power back on
• Ensure you are within range of the WiFi network. Sometimes if your phone is not picking up a quality network signal, your phone may swich back to LTE.
• Is your phone fully up to date with all software updates?

Also, I would suggest going to a local Comapny AT&T Store and getting a new SIM card, which can fix a lot of connectivity issues.

Hope this helps!

I ended up having to do a complete hard reset.  There were other issues my phone was having as well, such as connectivity problems - for some reason even though the phone was showing I was connected to my WiFi I was unable to access the web or anything - no email, facebook, browser, nothing.  I would get a message like 'connection error', in which case I would have to power off the phone and restart it.  It seemed that between connection errors and switching back and forth between data and wifi all I was doing was turning off and restarting the phone.

I had connection problems with my last two smartphones as well and I had to do hard resets on them as well.  Probably at AT&T thing.  The salesguy at At&T was useless; all he wanted to do was sell me a new phone.

So anyways for now, it's working fine.

I also went ahead and did a full reset and everything is good again.

Here's the way to do it.

Download Kies3 to your computer and install it.

Run it and back up everything in the phone.

Hard reset the phone.

When it comes back, don't put in any google addresses, emails, or wifi passwords.

Just get to the home screen.

Connect again to Kies3 and restore from the file you saved.

Your phone will come back to life and even the wifi passwords will be there.  Most apps will be current, some will have to update via Play store.

All texts are there too.

All custom ringtones and pictures as well.

However you will have to link the ringtones again.

Bluetooth is restored but would not connect to my car.  Had to delete the pairing in my car and redo it.

All in all, it took about 3 hours from start to finish.

But the phone is good, no problems.

Samsung and AT&T could save us alot of grief by avoiding this 3 hour step.

Hello. I encountered the same thing. What's happening is that AT&T is controlling our phone's connectivity controls rather than allowing our freaking phone to do it like it should. They did this on the sly and I'm sure racked up millions in data overage charges on millions of unsuspecting customers. It's not their right to control our phone's settings. I don't think removing their app will fix it. I'm complaining to someone, but not sure who.

Incorrect.  

If you are having trouble understanding and controlling data, this article may help explain.

 BTW. iPhones are well known for data overage due to connecting to cellular over wifi.  BUT! iPhone also have ZERO carrier software.  No carrier controls how iPhones work!

Your phone is not under remote control by ANY carrier.  The top bar of your phone will show all possible connections, irregardless of connection.  You can turn on Bluetooth, NFC and have nothing to connect to, those will still show.  

My phone and tablet always show wifi and Cellular in the top bar.  It will ALWAYS, ALWAYS show the status of your cellular connection on a phone.  I have never had excess data charges.  

Your PHONE IS designed to chose the best connection possible.  Usually wifi is that connection.  But if your wifi is unstable, very poor, or congested with wifi only devices, your phone has no choice but to choose a viable connection.  

You can force your phone to use wifi by restricting background data, turning off wifi assist and making sure all apps are set to use wifi only for services.  Many of these settings are within the app itself (i.e. Facebook, YouTube and other social media)
