OSX location services not available

Funny this question does come up that often - it's neither a router not an ISP issue.

Apple (and for the sake of it also Google and others) are maintaining location service databases, allowing non-GPS equipped devices to get location information - which is based on information collected from GPS-assisted systems while accessing your wireless SSID, plus some.

When you bring up a wireless AP with a new name (SSID) not used anywhere, the MacOS (and other systems) will fail to find any correlation in the database - so no location information. When you are using Apple systems with GPS, which are accessing your WiFi and have the location services enabled, the database will be propagated. Similar with Android devices and Google.

Now we have those privacy fans which are disabling any kind of location services on their mobile devices - so your WiFi network name (SSID) and whatever other factors are taken into consideration (ESSID, router MAC addresses, ISP, IPv4 subnet, ...) will never make it to the databases.

In the past, Google collected wireless names while doing the data collection for Google Maps, Street View & Co. This was forbidden by some law makers for blah privacy reasons in some countries.

Don't know what people expect ... location information from a router, fiber endpoint coordinates, ... there is no "magic".
