Wi-Fi will not work unless I turn off my mobile data. I didn't have an issue with this prior to the update, is there a fix?
It seems to prefer 3G/4G for the initial connection, but it I turn data off, connect to my router, then turn data back on, everything works fine. The Data ON-OFF widget makes that easy.
You don't have the option checked in WiFi settings that says automatically switch between WiFi and cellular do you?

i have the samsung galaxy note gt-n7000 the problem is when i want to use wifi i have to turn on the data too because i can't use just wifi i get no connection anybody have any suggestions
you can't use both of them at the same time... remember your phone has 2 radios.. Wifi, 3G.. your phone would switch radios from one to the other. IF you want to use wifi, it turns off 3G and vice versa. You can't have them both. Though you can connect your phone to your home router and at the same time mobile data would be ON. but when your going to go online... your phone would toggle between two radios and normally it would be using WIFI and temporarily disabling your 3G/4G connection. When your done with WIFI and turn it off, then that will be the time 3G will be enabled again.
That's how it is usually implemented.. not just with the Note but with any smartphones out there.
Web u on wifi... Data goes to off automatically.. How can u on both of them?

Hello. Does anyone knows how to make a script for tasker which switch mobile data off if WiFi is connected and mobile data back on if there's no WiFi connection? For the last 3 or 4 hours I'm searching for this and can't find nothing.
Also, I want if there's no WiFi network, to switch WiFi off (so mobile data will be turned on).
I managed to do something, but it didn't worked. When I enabled the profiles with WiFi and mobile data both turned on, the mobile data turned off, then WiFi off, then mobile data on and so on, in a loop.
Wouldn't that be redundant? The os already does that.

Thanks for the response. I know that if WiFi is connected, I'm using the internet from it, but mobile data is still active, right? Even if there's no traffic from mobile data, that's still on. Wouldn't that be a source of battery drain?
I set my data to turn off if my phone is connected for 5 minutes to a wifi. Important: set collision handling to 'abort existing task'.
Here you got pictures.
Edit:
if you are further interested in battery savings, you can read my thread "[BATTERY LIFE] How to get up to 7+h of screen-on-time"
This is absolutely redundant and unnecesary, when the phone connects to a wifi, it disables 3g/LTE data connection by itself. When you connect to a wifi you can see how the 3g/H/H+ icon above radio signal dissapears. The radio chip inside this phones can be used in Wifi mode or 3g/4g mode for data connection, but not both at a time. It is technically not possible.

The moment you don't have wifi anylonger, the phone starts a fullburst search for wifi and 3G/4G networks (even if I don't want wifi/data at the moment). and this drains a hell of a lot of battery. then (if you go out e.g.) it finds a 3g/4g-connection which it tries to keep up (drains a lot battery) and in the same time searches for wifi-networks (also drains battery)... very inefficient use of battery
So I deactivate data after 5 mins automatically via tasker and turn it on manually when I need it (could also automate that, but I'm lazy). This way I circumvent all these battery drains
Additionally:
Under normal circumstances I'd also set wifi to "turn off if not connected" (in settings) and "optimize wifi for battery life", but I use a custom stock kernel that has issues with these settings so I need to leave wifi on all day

Umm, ok... But this has nothing to do with what the OP asked, or what I said.
You may try e-robot from play store.
I have a command for that, after wifi disconnects, wait for 30 sec. If still wifi is not connected, automaticcaly disables wifi.
Same as for bluetooth. When i leave my phone in my desk and gone for a while, 60 sec later disable bt.
You can do what ever you want.

So I bought a Xperia z1, used if it matters, and it is having this issue. When I'm done using WiFi and turn it off, the phone can't use the internet, even though the connection seems to be running (full connection bars, H+ symbol) but no data is able to move whatsoever. This doesn't occur every time though, it may as well work just fine. Yesterday I didn't use WiFi and the mobile connection worked the whole day. It also occurs sometimes when I boot the phone. Turning on/off the mobiledata or the airplanemode might work and get the connection running. Sometimes. This is frustrating as hell. I'm running android 4.4.2

Have same problems on Z1...
Now my wife use it and she said it's fixed now on 4.4.4 (108)
I found out that mobile data will work fine if I turn wifi off, wait second or two and then turn wifi on.

That's fantastic news if true! Hopefully the official update lands soon here in Finland...

This part I don't understand. It doesn't make any sense to me. How can you use mobile data when you are connected to Wifi? The problem for me is when I use wifi at home and leave (=no wifi available, I turn it off), the phone can't use internet using mobile data (wcdma in my case). Are you saying that you put wifi on even though there's no wifi connection available and then mobiledata works for you?
Anyway, thanks for your reply I really appreciate it!
Haha...sorry...
I mistyped that...
It should wrote - turn wifi off when you are leaving wifi area wait two seconds and then turn mobile data on.

Is there a way to have WiFi calling turning on automatically if the phone connect to WiFi and have it turn off when the WiFi connection is lost?
I read something in the S5 thread about changing some settings by use of ROM Toolbox, unfortunately it breaks the link to the WiFi calling app. Besides, it didn't seem to work on my m8 hk stock.
Hi, I have an S21 Ultra 5G, (SM-G998B)and I have problem about 1 month ago. When I am connected to a wifi network, icons 4g is turn on and mobile data stop work. Only way to turn on mobile data is restart phone. What is the problem? I try everething and hard reset but problem not solved. This happens almost every day once or twice
Not sure I understand....the phone will NOT use mobile data when on Wi-Fi. You can force it by going in developer mode and boost speed by using both, that is not the default though. ("Mobile data always active")
"Mobile data always active" is turn off but 4g icons is active in same time as wifi network. After that I turn off wifi and mobile data not work but 4g icons still turn on.
I found out what the problem. Every time after sharing the mobile network via hotspot, when I go to Sim manager and turn off Sim 2, both icons appear and the mobile internet stops working.
1. Turn on sharing mobile data (from sim 1) via hotspot. (sim1 and sim 2 active)
2. Turn off sharing data via hotspot
3. Connect to any wifi (after connect to wifi, only wifi icons appear)
4. Go to sim manager and turn off sim2.
5. After that, both icons (wifi and mobile data) appear and mobile internet stops working.
Does this happen to others?
