=== Notes for Testing === | |||
There was a patch that now caches queries, so we do not ping the server every 5 seconds for geolocation data. | |||
Shutting off wifi : (Bug 1014924) | |||
Expected: that shutting off wifi should shut off wifi scanning | |||
Actual: does not shut off wifi scanning, no change in geolocation because of this. | |||
When using mobile SIM: | |||
geolocation should scan cell towers and try to use multiple | |||
currently on all devices seem to be only using one cell tower and not triangulating | |||
GeoIP : | |||
worst case scenario uses GeoIP | |||
how to set this : no cell tower and no wifi scanning | |||
no sim turn off wifi | |||
GeoIP is very approximate | |||
