My home internet connection is unreliable sometimes. The WiFi works fine. When I'm at home, if my phone is connected to the WiFi and the internet connection goes out, my phone won't use my mobile data connection to connect to the internet unless I manually turn off the WiFi. Is there a fix for this? I would like it to automatically switch to using the data connection whenever the WiFi internet is down. I have looked for apps to do this but haven't found one that looked good. Any advice?
