WLAN and mobile data at the same time - OnePlus 3T Questions & Answers

Hello,
first of all, my English isn't that good, but I hope you understand it well enough.
I own a OnePlus 3T and want to run wlan and mobile data at the same time,
but every time when the OP3T connect to a wlan the mobile data stops working.
I know there is a developer option for wlan and mobile data, but it didn't work for me.
Nothing changes. Even with a reboot, the mobile data still automatically switched off as soon as a wlan connection is established.
Why I need both running on the same time:
I've got an OBD Dongle for realtime information from my car (because my car dies slowly and I want to know what is going on with this "lovely piece of something")
My OP3T connects via wlan with the device, which means that mobile data is automatically deactivated, which also means that I have no connection to the internet.
Has anyone of you a solution for me?
I must confess, that problem is quite depressing for me.
If you can't understand what i'm saying or have trouble to understand, then just tell me and I try to rewrite my problem (somehow i guess)

Wifi NOT work at all??

I use public wifi in my school. I registered it and it s connected every time i turn it on. I have a good speed(58Mbps), OPEN security and a IP address. I used an app to moniter the data useage and there is a small amount of data use when i keep the wifi connected.
ANYONE KNOWS WHY??
THANKS A LOT.
ok not sure I am following you.
in the title you say wifi is not working yet you say you have a IP and it is connected then you say that you see data passed. So what is not working?
When you have wifi on at school can you browse the web?
Were is the data that you see 3G or wifi?
Why do you think that wifi is not working?
are you getting errors?
guess I am saying we need more to go on here. Details man we need details.
If I had to guess
If the small amount of data that you see is in 3G then that may be the phone "signing out" of 3G
If the data is on wifi then it is the phone registering on the network.
but still need more details.

Okey, I should not say wifi is not working. It is connected for sure, but when i use the browser or the market or any app that requires internet connection it never works. It does not show web page, app store content or anything from the internet. Maybe it is my phone? this phone works in some other spot in my school,but no way to use wifi in my own dorm.

and also I turn off 3G when I have wifi, you know some widgets can help turning off 3G, so I can save some data. It is just the wifi data count that shows a data use.
I am pretty sure it is this phone s problem. I just got my ipod touch and I test the wifi on itouch. Touch works perfect. Why this good looking captivate has so many problems?

[Q] Automatically change to mobile data is wifi data speed too low, like in BB

Hi.
Is there any way for our android device to automatically start using mobile data even if its connected to a WIFI network, like it does in Iphone and Blackberry.
There are times you go to a certain location and having used their wifi before, your phone automatically connects to it only to find out that no data is transmitting and you can sit there for hours not realizing your phone is disconnected from the internet whereby, in BB or iphone, the phone just switches over to mobile data and keeps you online.
Most apps available just toggle wifi on and off but none I've seen can keep WIFI connected and still use mobile data.
Any help will be appreciated
There is an option, that the phone only connects to wifi if there is a good connection (under wlan --> advanced )
Hope this helps.
Same problem (but inverse)
Hi everybody,
I'm facing the same problem, just inverse: when the phone "considers" the wifi signal "too weak", it automatically switches to mobile data (even if the latter are disabled), the result is the mobile frequently drop the connection in some places at home where the signal is a little less intense.
In my phone, the option mentioned by Marc199 doesn't exist (or isn't displayed)...
What can I do?
Is there a way to access "hidden" settings like the one mentioned?
Thanks for your answers!

Well, you can always use the quick settings to turn off the mobile data.

Well, there might be a chance that HTC removed (or never implemented) this feature. I'm using a GPE ROM.
If you mean the developer options, they won't be any use to you.
BestSignal Wifi-->Mobile Data App
I just installed BESTSIGNAL on my **HTC ONE M7**from the developer of the same name (BestSignal).
It's the paid version but only AUD1.99 and it works well, simple yet highly functional GUI. However it was not compatible on my Google Nexus 7 (2012) nor my ASUS Transformer TF700T so be sure to check your device compatibility.
As a XDA newbie I'm not allowed to include active HTML links so the App URL extension is: details?id=com.eightythirty.bestsignal and the Dev's is: developer?id=BestSignal

Mobile Data Auto Off

Could not find an app where once Wifi is connected, Mobile Data is disable and enable when there is no Wifi connection.
Hope someone can help, thank you.

when the wifi is connected mobile data automatically turns off you dont need a app :/
Thanks are you referring to the Auto Network Switch under the Wifi setting?
When I set to Yes it gave a warning that it may auto switch to Mobile Data.
Suspect that if Wifi is not strong but still connected, it may switch to Mobile Data to get better connection which I do not want.

I'm in the complete opposite camp, how I wish there's an option for the phone to automatically switch to mobile data when the wifi becomes practically unusable.
There's a wifi deadspot in my house where I often use the phone, and contrary to what you suspect, my observations indicate that as long as there's a wifi connection, no matter how weak the signal, the phone will try its best to send and receive packets over wifi.
I usually have to manually switch off wifi.
Thanks for your feedback.
I will monitor whether the outcome is similar like yours.
I will turn ON both the Mobile Data and Wifi and using the Wifi preference setting.
If it works as you have stated, I will be very happy.
My priority is saving the cost from Mobile Data which is expensive to me.
I would like to control all downloads/updates of apps through Wifi.
Will use Mobile Data only when Wifi is not available/connected.

There is an option in developer settings to keep mobile data active even when Wi-Fi is connected. That may help with your Wi-Fi dead zone.
I think this option works for one device only.
I would rather recommend deploying a repeater for the Wifi signal, which will serves all devices at the dead spot.
A simple repeater should cost about USD10/

Thanks Pakman123 and mhaha, for sharing your experience.
So far testing as recommended works according to your views.
For mhaha, I believe a wifi signal repeater set up will resolve your concern.

You can look at which apps are thirsty data eaters in settings under mobile data usage. Then click on the hungry app, untick background data.
Turning off background data will keep the apps restricted to WiFi slurping.
Thanks for looking up.
Appreciate your good suggestion.

Sony RX100 ii connectivity

Hi anyone have experience with connecting the n8 to this camera? Using the sony memories software it tries to connect but disconnects immediately. Any ideas folks.
I have an A5000 but i believe the method should be same.
When using wifi transfer i set it to wifi direct rather than through a router/access point (never had any success with using wifi router), when connecting directly to the camera the phone will complain about no internet access, make sure you pull the drop down and select stay connected anyways (otherwise the note may drop the connection so i can reconnect to your router that does have internet connection)
Found the solution I had to disable mobile data. Only found this out this by checking whether it worked on my tab s3 and it did so was a matter of deduction. Thx

strange mine works fine with mobile data on, do you have the switch to mobile data when ever your wifi internet connection is slow or unstable turned on in the advance wifi options?

Question Data connection is active even when on WiFi

Hi all,
I'm noticing that the data connection seems to be active even when on WiFi. Is there any option that I need to disable so that the phone runs entirely on WiFi. I looked in the developer options and keep data alive option is unchecked. Am I missing something?

Hi, just go into Wi-Fi Settings / Advanced and switch off tab (Switch to mobile data)
That's all.
Hi. Thanks for this but this option was never enabled in the first place. Anyways, it's self corrected now...aah..the wonders of the tech world

It's enabled by default just to keep your internet connection stable when wi-fi has an issues.

It will re-appear occasionally. Even if you turn off the "Switch to Mobile Data" setting, the mobile data icons and wifi icons will appear concurrently on the status bar. This happens even when the wifi connection is solid. Usually the mobile data icon disappears after a few seconds or minutes on its own. I'm not sure if its by design (for MMS or RCS or something else) or if it's a bug. But you're not the only one seeing this. My colleague has an S21U too and he shared a similar experience.

I'm suffering from the opposite problem!
I *WANT* to keep mobile data enabled while connected to Wi-Fi, but the setting on my phone has no effect! When I turn on the setting, my phone will still ignore mobile data.
I verify this by connecting to my dashcam via Wi-Fi. The dashcam does not provide any internet via Wi-Fi, but merely allows my phone to view the dashcam output and stored files. But once I connect my phone to the dashcam, then my phone has no connection to the internet. I can't force it to use the mobile data at that point. The phone is not behaving as it should. My older phone, LG G6, is able to successfully connect to the dashcam and still access the data through the cell signal.
The S21 Ultra simply cannot achieve this. I have the T-mobile variant, in the US.
I believe this is a bug. Can you get this setting to actually work? Like maybe test it by connecting your phone to your Wi-Fi router but disconnect the modem from the Wi-Fi router?
I'll post a separate thread for this, because I think it's a bug and maybe others are suffering from it without realizing.
