OK, both match my output. I then changed the location to “Darwin,Australia” and after a minute or two, the “wl” changed to 122. You can try it and if you still see 19, I suspect there is a caching issue somewhere — in other words, the controller sends out a query with the new location, but instead of reaching the server, that query may be immediately returned by your router or some intermediate server with cached results. This is really very rare but it’s the only thing I can think of.
