Mobile connection is not restored after after my phone tries to connect to an open wifi

I am running e/OS and have posted about this issue before on their discussion page. It is annoying as hell. I left early today and for the whole day I could not get mobile internet. This is unacceptable. Please help.

So anytime I pass an open wifi (no matter if I connect or not) mobile internet is dropped and stays dropped sometimes for 30 min sometimes for the whole day. Switching from 3G to 4G sometimes helps (there is no logic), also connecting to my home wifi kinda resets things.

I have tried everything: reseating the SIM, new SIM, ON/OFF, all kind of settings etcetc.
The strange thing is that Whatsapp always has internet (I can send and receive messages), the browser sometimes. Only thing I can think about is that is some issue just in between the hardware and OS: where the OS is set as having no connection when in fact there is. Most apps ask the OS if there is internet available (and they get a ā€˜no’), while other apps like Whatsapp just connect without asking the OS.

I am running OS 2.9 on FP3

From what you say, coming within range of any open Wi-Fi network that the phone can start connecting to, gets it into a muddle.
In your place, I would turn off Wi-Fi except when I’m within range of a network I trust. That way, the phone will stay on mobile data unless you specifically enable Wi-Fi for a known network.

A little effort, but a swipe and a tap is all you need, and that will save you lots of hassle.
:sweat_smile:

Thanks. I see there is a toggle button for this in the pull down menu. But remembering this each time I leave the house … :sweat_smile: and especially not undoing this when I enter could waste my mobile budget. But if it works, it might give more insight in what is going on.
What also frustrates me is that I don’t feel this is an issue with my phone specifically but with either FP or e/OS. Yet there is almost no one having a similar problem. Only: Phone doesn't connect to mobile data after leaving home wifi

As you write

it came just to my mind (so really only a ā€œshot in the darkā€) if it somehow be related to ā€œadvanced privacyā€. Do you have ā€œhide IP addressā€ enabled? If yes, have to tried to disable it?

Thanks, last week I explained my problem to Claude.ai. It immediately identified the problem: it was my Access Point Name which was not correct configured or not optimal. I have never touched those is they are configured automatically even when I created a new one, the same troublesome configuration was loaded. Claude.ai told me what to adjust for better performance and up to now no more problems. It was several settings so I don’t know what did the trick and I am not messing with it to find out.
