Hi,
does anybody of you have problems when connecting to an unsecured free wifi network? Most of the networks require accepting some rules after you have connected (via a browser page).
In KitKat, mobile network was disabled as soon as I connected to a wifi. So I could open my browser and the "usage terms" page of the wifi appeared.
With Lollipop, the mobile network stays enabled as long as the wifi network can't access the internet. So I can't open the web page for accepting the usage terms of the wifi... ---> using an unsecured wifi is only possible when I turn off mobile data before connecting to the wifi...
Regards

Hi there,
I have a question about an annoying problem that I've only managed to find one (unanswered) question to on the web.
I have an HTC Touch HD (WM6.1) which I use to read email from my Hotmail account, amongst other things. The problem is that the messaging client ALWAYS tries to download my mail via 3G/GPRS even when there's a WiFi connection available. This occurs both when I initiate the send/receive using TouchFlo 3D or from within the mail client.
Connection manager is, as far as I'm aware, configured correctly, and PIE/Opera/weather will all happily use WiFi to connect to the internet, only using my data connection when WiFi isn't available.
The same results occur with connection manager configured in either of the following ways:
Internet Connection = "My ISP" settings with 3G modem connection
Work Connection = Default "My Work Network" settings
WiFi Access Point = Connects to Internet
Network Card = Connects to Internet
OR
Internet Connection = "My Work Network" with 3G modem connection and "This network connects to the internet" enabled
Work Connection = As Internet Connection
WiFi Access Point = Connects to Work
Network Card = Connects to Work
Interestingly, if I disable my data connection and enable WiFi I CAN send/receive mail over the WiFi connection, so it seems like the data connection is being used in preference to the WiFi one.
Is this a known issue or am I doing something wrong?!
Thanks,
Mike
What´s the version of your ROM?
Is the device labeld by Vodafone?
There is an option when setting up the email account in pocket outlook to select the preferred connection for the account. It is in one of the advanced options pages when setting up the account. Normally it is setup for THE INTERNET so your WiFi adapter should point to the same.
Now, I use a little Mortscript to switch-on the WiFi and immediately change my Network Selection to NO DATA, which is just an empty setting (no internet connection). This effectively shutdowns the GPRS / 3G connection and pocket outlook has to use the WiFi route.
I have a NAS drive on my local network. The network doesn't have internet access. How can I get my phone to use its mobile data when connected to my network with wifi?
Hi !
It is impossible to use mobile data when connected to a wifi access point , even though that wifi it has o internet access , one data connections cancels the other one
So , the mobile data module can`t be active in the same instance with the wifi module
Hi:
In all my phones with pure android (Nexus 5, Nokia 8) whenever the phone connects to a guest wi-fi that needs authentication via a captive portal (Fonera wi-fi, for example), they keep the operator data connection active until i authenticate on the wi-fi network and get a internet connection.
On the OnePlus 8 i just got recently this does not happen. As soon it connects to the wi-fi network, it disables the operator network data and i loose internet connection until i authenticate on the wi-fi network. Is there any hidden option to correct this behavior?
Regards.
I have an RV that allows me to control everything their their app as long as I am connected to the RV's local WIFI network (which doesn't provide internet).
It is obviously a terrible design as I cannot access the internet if I want to stay connected to it.
I know that about the "Switch to mobile data" option, but this doesn't work as this disconnects me from that WIFI connection. So that means I actually have to put the connection as a "Network exception" if I want it to stay connected.
Is there any work around to stay connected to a WIFI connection, but use mobile data when on that connection?
(Samsung note 10+ Android 12)
Always thought
a carrier's cellular network ( a radio network distributed over land ) is used when sending / receiving mobile data,
an internet service provider's network ( accessable via router / access point ) is used when sending / receiving data to / from internet.
All Android apps have a default network. The system decides which should be the default network.
It depends on app's configuration what connections - if available - are to be used - even simultaneously.
Hello,
I hope you can help me with the following questions:
When you connect to a WLAN, Android automatically determines whether it has an internet connection.
If no internet connection is detected, you are still connected to the WLAN (or a message is displayed that there is no internet connection and whether the connection should be maintained), but the data traffic is routed exclusively via the mobile network.
Now I have a network device that sends out its own WLAN but does not have Internet access itself. When I connect to its WLAN, I still cannot access the device because it recognises that no Internet connection is possible via this WLAN. Only when I explicitly switch off the mobile data can I access the device via the WLAN.
So I did some research to find out what mechanism underlies this behaviour.
What I have already been able to find out is the following:
When connecting to a WLAN, Android checks the accessibility of https://connectivitycheck.gstatic.com/generate_204. If this URL is accessible, data is also sent.
If this URL is available, data traffic is also routed via the WLAN.
So I reproduced the URL using these instructions and made it accessible locally via a redirection at my DNS server.
Now a connection to the device is actually possible via the WLAN without having to explicitly switch off the mobile data.
However, Android still recognises that no internet access is possible via the WLAN.
As I understand it, this should not be the case, since I am simulating existing access via the reconstructed connectivity check URL.
So there seem to be other mechanisms here that check the internet connection.
How exactly is connectivity checked on Android?
Can anyone tell me what other mechanisms exist here and how they can be simulated?
The second question I have also concerns the WLAN.
When I am connected to a Wi-Fi network, Android sometimes reports that the quality is low even though the Wi-Fi reception is excellent and the signal strength is also displayed as "very good".
I don't have any network rating provider active in Android.
How does Android determine that the quality is low and how can I prevent this check?
What criteria are used to rate networks without a network rating provider set up?
For completeness:
In the developer options of my smartphone, the setting "Mobile data usage always activated" is of course active.
