How To Fix Samsung Galaxy Note 3 Wi Fi Mobile Data Connectivity Issues

First, try restarting the Galaxy S6. To do that, hold the power button on the right side of the phone until prompted. Hold it down again to turn the Galaxy S6 back on. It's a simple process but it has been known to dislodge Wi-Fi issues
If that doesn't work, Galaxy S6 users will want to try rebooting the local router if that hasn't been done in awhile. We recommend unplugging the router for a good 30 seconds and then plugging it back in. Users can do the same for the modem as well. Galaxy S6 users might also consider updating the routers firmware. This process will be different depending on make and model. If those simple fixes don't work, it's time to head into the Galaxy S6's settings.
If the Galaxy S6 isn't getting a solid connection, it's time to force the device to forget the Wi-Fi network in question. To do that, head to the desired connection in Settings. On the Galaxy S6, this can be found in the Connections portion of Settings. Once there, select Wi-Fi. Tap on the desired network and select the Forgetoption. Users will then need to reconnect to the Wi-Fi network. Make sure the password is readily available or the device will be locked out.
If that doesn't work, head into Wi-Fi, tap More in the top right corner, and select Advanced. Ensure thatAlways allow scanning is turned on. You'll also want to make sure that Keep Wi-Fi on during sleep is set toAlways.

Are you trying to connect via wi-fi or via bluetooth? Typical hotspots are wi-fi, and that can be as easy as turning on wi-fi (in Settings, Wi-fi - see manual or quick setup brochure) then waiting for it to find an active hotspot and plugging in any necessary password. Bluetooth is much less common. Post more info and I'll try to help more.

Hello Ricardo.
How are You? I Guess you need to
1- Check your wi-fi router model.
2- Check your wi-fi settings.
also please check how many devices are connected to your wi-fi at same time. because some routers can only support upto 5 device. you can check this in the settings and also routers manual.

Please let me know, once you done with it.

Regards

Solutions to Common Android WI-Fi ProblemsFriends of mine who use an Android come over to me usually with problems related to their devices' Wi-Fi connectivity. Moreover, it's not a single isolated issue. There are all kinds of them they bring up. I usually fix their problem after few troubleshoots but today while I was fixing a problem on my device, I realized that it could happen to any one - even to my readers on Guiding Tech. Hence we are going to discuss four of the most common Android Wi-Fi problems and see the probable causes and solutions to them.
Android Cannot Scan a Wi-Fi Network Reason
There may be two reasons as to why your Android cannot scan a network automatically. The first reason may be that the network you are trying to connect to could be Ad-Hoc in nature. As most of the Android phones are not configured to work on Ad-Hoc networks but on access points, they don't scan them.
The second reason may be that the Wi-Fi network you are trying to connect to might be hidden for security reasons.
Solution
By default, Android does not support Ad-Hoc Wi-Fi network but many developers patch the wpa_supplicant file on Android in order for them to work. If you do a quick Google search you will be able to find if there's a fix available for your device but the fix can only be performed on a rooted phone. Furthermore, don't forget to back up your original wpa_supplicant file if at all your phones goes into foreclose or boot loops.

If the problem is with the hidden network, you can try to add the network manually. In Android Wi-Fi settings open menu and tap to add a network manually. You must enter the correct SSID and authentication type and password in order to connect to the network. If both the credentials are correct, the Android phone will be able to connect to the network.
Wi-Fi Keeps Disconnecting Frequently Reason
The most obvious reason for the problem may be with the Wi-Fi Sleep Policy which disconnects your Wi-Fi every time your Android goes to sleep to save your battery's juice.
Solution
To manage Wi-Fi Sleep Policy, open Advance Wi-Fi settings on Android and tap the option Keep Wi-Fi on during sleep. Here, check the option Always to enjoy an uninterrupted connectivity, but you will have to compensate it with your battery life.

If you are using any third-party app to save your battery, check if it's controlling your Wi-Fi and other radio services and configure accordingly.
Obtaining IP Address Infinite Loop Reason
I don't know the exact reason behind this, but it might be a bug in Android. I have seen many people getting this problem, and it gets kind of annoying when the problem does not gets fixed even after restarting the device.
Solution
First of all, you must restart your Wi-Fi router and see if that helps. Many people say that resetting the phone to factory state works but that's not an appropriate solution. Wi-Fi Fixer is an amazing Android app that can help you here. The app resets your Wi-Fi system files (same as when you reinstall the Wi-Fi drivers in Windows, or you disable and enable the Wi-Fi adapter) and services and helps you to connect to the network and obtain the IP address.

If you know the range of IP address the router is broadcasting, you may configure your Android to use static IP address while connecting to the network.
Can't Connect to Internet using Wi-Fi Reasons
There may be several reasons as to why you are not able to connect to the internet even when you are connected to the Wi-Fi. The reasons may be:

• The router is not broadcasting internet services.
• The IP address or the gateway is wrong.
• Problem with the DNS settings.
Solutions
You may use another device to check if the router is actually broadcasting internet. Also you can configure the IP address, the gateway and DNS manually to connect as their might be problems with DHCP.
Conclusion These are pretty much most of the Android problems one might encounter on his device and the probable solution one can try to fix the problem. I don't guarantee that you will fix the problem but it's a good start nonetheless. And most of the solutions should work actually.

Thanks .

Thank you for the Video, this made it much easier for me to determine the problem. You are correct, you have WiFi, this is not the problem, the problem is with the Tablet's WiFi Service which is freezing, thus not causing you to access WiFi.

Have you installed any new software lately? Something has broken the WiFi software on your Tablet. If you installed a new App recently, remove it to see if that new App broke your WiFi software on your Tablet. If you have not installed anything new on the Tablet maybe the manufacture downloaded an update that broke the WiFi on the Tablet. If you recently received an Software update from the manufature, let perform a Factory Resetr on the tablet to fix the issue.

I just had this same problem - I suspect it may have been a new app I installed that changed some settings.
I fixed mine by going into Settings>Mobile Network settings, then tick "Use packet data". Worth a try.

I HAVE THE OPPOSITE PROBLEM, I WANT WI FI TO WORK WITH OUT PHONE SERVICE ACTIVATED. IS THIS POSSIBLE?????
