I've experienced this behavior too. Reboot solves it for sure, but what an inconvenient solution! :-P (I've not tested cycling airplane mode).
The last time, today, on BQ45 r25. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to indicator-network in Ubuntu. https://bugs.launchpad.net/bugs/1477342 Title: Data network not reconnecting Status in indicator-network package in Ubuntu: Confirmed Bug description: BQ Aquarius 4.5 15.04(r24) Network is not always recognised. After time or when I move from a wifi to mobile 3g connection the phone will do either: 1) not connect to mobile network, even though from the network dropdown bar, it shows a data network is available next to sim1 slot, but topbar shows wifi not connected icon and no network is accessible on anything. 2) when wifi is available, it keeps me on mobile data connection and doesn't refresh available wifi networks. Number 1 can sometimes be corrected by entering flight mode and back again - sometimes. Number 2 can be corrected by switching on and off the wifi mode.
