Hi, I'm using mi2s, latest ROM (3.10.25). After some time of inactivity (more than 30 minutes) phone looses ability to use WiFi. While status bar and settings shows [connected] no network activity could be done. Even with cell data on, no network activities. Only way to fix it (temporary) reconnect to WiFi. Settings or toggles doesn't matter, works both. Already tryed rebooting router - same. Tomorrow I'll have oportunity to check this issue with work place WiFi (to eliminate home router as issue), but so far I'm asking You for a help to pinpoint issue.
