Mobile data disconnects while on wifi and silently doesn't reconnect
Symptom: When a wifi network goes out of range, the status bar continues to show a live internet connection. However, there does not actually appear to be an internet connection: Outgoing connections receive no responses (e.g., DNS requests from Firefox time out). Toggling the modem kill switch or toggling the "Mobile Data" setting in the Mobile Settings tab both usually resolve the issue.
I started noticing this about 2 months ago, and has been quite consistent. It's possible that it was an issue prior to that, since this is about the point where the kernel update that stabilized the modem connection was released.
