The geolocation Opera uses, whether obtained from the Windows API or from the IP address is not correct. It's 1,200 kilometres off. There's no way to manually override this incorrect IP address. This makes using websites that rely on this geolocation through Javascript a hassle. Some websites cannot be used at all because they, as well as Opera, also have no means to manually override an incorrect location. Geolocation from IP is very inaccurate. Geolocation from IP with no means to manually override is surprising. That's why I started this thread.

I checked the backyard, thanks

Site was using Javascript geolocation API

I'm using Opera 38 for Windows

When websites ask Opera for my physical location, the browser sends an incorrect location. Perhaps Opera's Location is based on either my IP address or what Windows is reporting (which is derived from my IP address, apparently.) In any event, both Opera and Windows always report an incorrect physical location. I have to manually correct my location every single time I visit certain websites, and other websites don't work reasonably well because they have no mechanism to correct erroneous geolocations provided by browsers.

Suggestion: manual override for physical location, in the form of City/Province/Country or latlng.
