My phone has access to various hotspot networks in the area I live in. When I walk down the street, now and again I pass by a hotspot and my phone will attempt to connect.
As often as not, the phone will connect, but for whatever reason, it will be a weak connection, and effectively my internet access stops. My phone abandons my cellular network connection in favour of the wifi, even though the wifi is bringing in little or no data.
Is there a way I can enforce a minimum standard of connectivity to a wifi network so that my phone won't leave my mobile connection in favour of hotspots that are useless?
