Togo - I'm on W7, so the W10 link doesn't seem to be relevant to me.
What puzzles me is that my wirelessly-connected laptop finds my location wherever in Europe I've taken it, whereas my desktop doesn't get it right. I can only think that something was set when my desktop was connected by cable and my recent experiments of using wi-fi instead have not managed to change things. Short of doing a complete rebuild and setting it up with the wireless dongle, I think I'm stuck with it. I only did a rebuild about a month ago and, whilst it's not difficult, I find it very tedious so can't really be bothered for such a minor problem.
