Use case: my internet provider offers wi-fi hotspots all over the country; I like to connect to them, but not when I'm home or at work. My phone seems to use one of the available wi-fi connections randomly; I end up 'forgetting' the provider's hotspot to assure connection to the wi-fi at home or at the office.

Windows 7 allows me to change the order of preference of wi-fi connections; that way I can tell my laptop to connect to my provider's hotspot only when no 'better' wi-fi is available.

Does Android have something similar?

I don't believe there is anything built-in for this, although some manufacturers may have added such a feature. There appear to be several apps that will do this.

I've always just manually edited /data/misc/wifi/wpa_supplicant.conf myself (root required). (Note that there are different files/locations for different devices.)

  • Yupp, beat me to it – I've had the same thought (so +1 is a must ;) For a "better listing", see here – not as complete, maybe, but hand-picked :)

  • How can I edit that file? Doesn't that require a rooted phone? Or can I do that via adb?

  • To edit that file you need to root your device. But most of the tools in the place I've linked in my previous comment (just added a few more there) can change the priority without root.

  • An app just needs WRITE_SETTINGS to do this, I believe. I am not sure if adb has that permission, but it cannot access the file directly without root.
