Hello, I've tried searching for this problem but didn't find anything. I have the problem that my phone often switches to mobile data even though wifi is available with a good signal strength. I think this problem existed some time now because I've been using all of my mobile data volume for the last months and had to pay extra. When I switch off mobile data it works just fine with my wifi. I'm using an Xperia X and my service provider is Vodafone Germany. The current sailfish version is anybody else facing similar problems or has an idea on how to fix this?

Workaround#1: you could explicitly turn off mobile data in the top menu when using WiFi.

Workaround#2: you could let Situations app do #1 automatically, I've never used that app myself though but am quite sure it's capable of that.

Have you enabled IPv6 in your wifi? If not, your issue is maybe related to the issue I disvovered: Mobile data usage via IPv6 while on wifi

I know about those workarounds but that's just what they are: workarounds, they don't really fix problem. Thanks for the tip with IPv6. It was indeed turned off at my fritzbox. I have now enabled it and will try the next days.
