Hi guys i am looking for an app that switches between wifi and 3g whenever wifi signal is low. i am not talking about an app that turns off wifi when the phone sleeps or wifi hasnt been used for a while or anything like that. neither am i looking for an app that detects location using towers or gps or anything like that to switch based on geographical location. half the time this happens at work (insane internet connection but several thousand wifi users) so location will show as having a good connection, but every now and then it gets clogged, returning again 30 secs later. sometimes when i am surfing i notice a significant slowdown and then notice that the wifi signal has dropped off to zero bars, but the phone doesnt seem to switch to 3g/data signal, just keeps trying wifi. presumably this is because it is getting a reply from the wifi origin, but not strong/fast enough to load webpages, so it acknowledges that it is connected but isnt getting the data. i want something that monitors the wifi signal when it is being used in the foreground, detects when signal is poor, and re-sends requests using 3g connection so that the damn webpage actually loads. of course it needs to start using wifi again if the signal improves. i dont want to have to notice that things are slow, come out of the browser to turn off wifi manually only to have to turn it back on to check if signal has improved 30 seconds later.
