How can I use cellular data while connected to a wifi without Internet access? - General Questions and Answers

I have Pi 4's that create a network in my car and boat for music control (J. River Media Center). But since those Pi's aren't connected to any 4G modems Messenger, mail, web reader and other Internet connected stuff does not work while connected to dem. I have read that going to developer's options and activate "Cellular Data Always Active" should work, but it doesn't. I still get no data in to them while I'm on the wifi without Internet.
I have also read that I can set the gateway on these two networks as empty, and then phone will automatically get Internet data from the cellular network. Only one problem: That's not possible because the "Save" button is grey when there's no default gateway added. Is there anything else I can use for this?

Wifi before gprs for email +web

Hi all - i have my xda mini s setup to connect to the internet and collect my exchange emails all works fine.
i use it at work + at home a lot and both locations have a wifi broadband network.
i would like my xda mini s to only connect to GPRS for web browsing and emails when a stored wifi network is not in range (eg when im on the road)
Is it possible to enter in this preference anywhere? thanks in advance for any help
Actually, as far as PIE or any program that connects to the internet is concerned WiFi takes precedence over GPRS by default.
The problem is MS push mail. It forces GPRS even if WiFi is connected. If you try to serf to a graphics heavy site wile connected to both GPRS and WiFi you will see the speed difference.
I am not sure what the logic behind this MS stupidity is, and unfortunately I don't know of any cure except deleting the GPRS settings.
hi - and thanks.
damn.
well i did have a qucik test i went on the web and it seemed to be connecting to gprs (while i was already connected to a wifi network)
i will have a play.
There's one other thing I forgo to mention:
When connection to WiFi make sure you select the correct value under "This network connects to".
I assume your GPRS settings are under My ISP and that is what's selected in Settings->Connections->Connections->Advanced->Network selection.
You should then select "The internet" for the WiFi network.

Dataconnection priority

hey, I have a problem with my HTC TP.
it always prefers the HSDPA link when connecting with a web based application souch as opera or MSN.
Even if I have it connected to a Wi-Fi it still boots up the HSDPA and goes online using that link.
I'm new to WM, so this is a bit vague, but I had the same problem, but I fixed it at some point last week...
There is a setting, somwhere (I told you it was a bit vague!), that tells programs to use WiFi as the default connection. I can't for the life of me remember where, and I've flashed roms since, but I'm sure it was a windows setting in "settings > Connections".
Sorry I couldn't be any more help, but at least you know there is a fix, somwhere...!
Hehe, thanks, I've tried looking for this feature for hours, becouse I can't for the love of whoever understand why there wouldn't be an option for it
there isn't one because it shouldn't need it. As long as your Wi-Fi is set to Internet, and Not work, it should always use that as long as it is connected.
Just having Wi-Fi turned on doesn't cut it.
There are certain applications that will always use the cellular network, like pushmail, but in general, all apps will use whichever internet connection is available. and if Wi-Fi isn;t connected, it will automatically connect to GPRS/3G.
Wellt hats the problem, I connected it t my home Wi-Fi set it as internet connection and the problem remains. I have redone the settings several times and it still prefers the HSDPA connection.
if I turn of all other alternatives to connect to the web, like removing APN settings for GPRS and HSDPA it uses the Wi-Fi, but as long as there is another Access link to the net the Wi-Fi isn't used
I have the same problem with Hotmail syncing (not defaulting to Wi-Fi), but not with Opera. I do have to change the connection settings though first from the T-Mobile Internet (and their magic transparent proxy) before Opera can work over Wi-Fi, but I thought the connection settings were just for HSDPA/GPRS connections. I'm finding this increasingly frustrating that I need to reconfigure everything depending where I am.
BTW, to get Hotmail to use Wi-Fi I have to go to the Comm Manager and turn off "Phone", turning off "Data Connection" doesn't work, because it craftily turns it back on, seconds later!

hotmail connected via cellar when wifi is available

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.

Need help, PIE or Opera will not load with Wifi

Okay for some weird reason, I have trouble opening PIE, and Opera. Iam able to connect to my router, and it does show the connected wifi icon on top.
-I have indeed disabled proxy.
-I have made Wifi slider to high performance.
-My router is set to b/g not n, and is set to Auto(WPA or WPA2), TKIP andAES.
-I also made my htc networkcard connect to internet, and set all adaptors to
server assigned.
-Oh yeah I also have disabled the router network passkey, but still could
get the same PIE error.
I spent alot of time trying to find the answer for this but nothing seems to work. If anyone has a remedy, or any suggestions please post..
settings->connections->connections->advanced->select network
is it set to my home network or whatever wifi connection and not isp connection
is called on your device?
What do u mean by home network or wifi network? The only options are medianet, at&t isp, my isp, and my work network.
If you mean my work network, I had it on the bottom selection where it says automatically connects to private network. The one on top says automatically connects to the Internet.

Using internet while connected to local WIFI

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.
