My route to and from work is populated by open networks from cable providers that require log-in via webpages and unsecured home networks. Whenever I pass them my phone tries to connect, disconnecting me from 3G. Leaving WiFi on all the time means I'm left with constant service interruptions. forgetting to turn on WiFi at at home runs the risk of eating up my data plan. For this reason I turn off WiFi when I'm out and turn it on when I get home. But what if I forget?
With this Tasker profile, my phone now uses cell location data to turn wifi on/off.
Steps:
Turn GPS on (just for now). You don't need to keep it running all the time, but it helps to pinpoint where your location for the context step.
First, go home (the place your wifi router lives).
Profile: WiFi At Home
Context: Location > Net=On, GPS=Off, Radius 500m, Get Fix
Task: At Home
Action: Net > WiFi > On
Task (optional): Alert > Popup > Text "WiFi On"
Task: Leaving Home
Action: Net > WiFi > Off
Task (optional): Alert > Popup > Text "WiFi Off"
Get Fix locates where you currently are on a map so you need to actually be at home for this step.
You have several setting options depending on how much power consumption vs. accuracy. See [html http://tasker.dinglisch.net/userguide/en/loctears.html "Location Without Tears"]. The least accurate (Net=Off, GPS=Off) needs a really large radius. The most accurate (Net=On, GPS=On) will drain your battery faster.
I find Net=On, GPS=Off, Radius 500m to work fine. My phone knows when I'm home.
