Wifi/Data connection issues - Galaxy S 4 Q&A, Help & Troubleshooting

Data connection doesn't automatically turn on after disconnecting my device from wifi. All I am doing is to flip the airplane mode to connect back. I believe this isn't normal
Stock Rom/device.

Checked with Samsung support and they suggest me to try with a different service provider (3g). My current provider says the existing settings seems to correct. Still I lose data connectivity often
I am yet to test with a different sim.

Does it happen on other devices connected via Wi-Fi?
My tablet galaxy p1000 and my laptob can connect clearly to the rooter, my mobile phone mt6575 ( android 4.0.4 ) can connect too but some seconds later link speed changes 54 mps to 0 mps. i tried to connect 5-10 different rooters, i would see same issue. Hmmm, mobile can do internet sharing very well. when i open mobile's 3g internet to sharing, galaxy p1000 and my laptop can connet to mobile very well and can use its internet.

Wifi conflicting with mobile data?

My wifi seems to be conflicting with mobile data ,
whenever i turn on mobile data, the wifi would disconnect saying
wifi is disabled because connection is slow,
This problem dissapears if I turn off the mobile data
Anybody had this problem?
Your WiFi connection is always too slow but you have it set to cellular preferred . so when you turn on data it prefers the stronger signal. You need to change the settings

[Q] 4.3 Losing Data when Disconnecting from WiFi

So I've been trying a few 4.3 ROMs and right now I'm on Beanstalk, but every time I disconnect from WiFi, I lose 3G/4G connectivity unless I go into Airplane mode and even then it sometimes won't reconnect. Any suggestions on how to handle this issue?

[Q] Disabled wifi disconnect on poor Internet connection speed

One very irritating "feature" on my note 3 is it's automatic network disconnect when it thinks the internet connection speed is poor. Is there any way to override this automatic disconnect? Particularly since there seems to be a well known bug with the galaxy range wifi network which thinks the connection speed is poor even if there is nothing wrong with the wifi signal or Internet connection speed.
Try this.

Unfortunately the wifi connection dropping issue seems to be highly dependant on your router.
Most people with the problem (including me) solved it with a different/newer router.
If you have spare time you could waste it ticking/unticking boxes in the wifi menu .. & THEN change your router lol

I am having the same issue on a corporate wireless network behind a proxy. It will connect, perform the connection speed test and then disable the network due to the connection speed being slow.
I am able to connect to a WiFi network on a secondary connection which does not go through the proxy. Both connections are on the same network.

Yes.... obviously an OS bug but we are stuck with it currently.
The information people need is how to COPE with the bug. I changed my router & no more problems so there's router's that will stop the issue occurring.

Turnoff wifi power saving mode. This should work.

Google account sync issues on mobile data

Hey, sometimes when I'm outside of the house, and try to use something like YouTube in a place with low reception, it just halts, loading very slowly and won't let me view any videos. However, after this, my Google account will fail to sync. Even after going to a place with better reception, it will fail to sync. And this happens to all the accounts on my s4 that I have set to sync. The only way to get sync to run again is to connect to a wifi network. I've tried clearing app data, enabling and disabling network data, and restarting my device, but nothing works until I'd have connected to a wifi network. Any suggestions or ideas?
