@scruffr is correct, these are the IP addresses of the access point your Argon is connected to. The google maps location service uses these to match against a database of WAP IPs that Android phones send it with their GPS data when connected to the WAP. Sometimes the WAP has never been near an Android phone/device and you will not get a location back! Experience with >500 devices all over the world suggests it very rarely doesn’t work. Accuracy with WiFi is 20m typically.
This info is sent to the Google Location service from where you should get a response telling you where these three APs are probably found. If Google has no knowledge about these APs you won't get a location result.
This is also what Rick was trying to tell you by linking to this
Did you care to follow that link and read about the background?
