If it's connected to 'your own' ISP then yes, the ISP usually gives an enquirer a location. This has got more accurate over the last couple of years (mine used to show as Essex, presumably where BT had some equipment).
If anyone with an Android 'phone looks at their Google Timeline - a brilliant function in Maps that conspiraloons will hate - they may see some aberrations, as
treadigraph noticed. I'm pretty certain that this is because when you're out and about your 'phone is noticing 'known' wireless hotspots and is navigating, very roughly, using them. All very clever, but when someone moves and takes their router with them it all goes to pot. 'Phone recognises a router that used to be in Lands End and that's what goes into your timeline, no matter where you were. I should add that if you've fired up the 'phone's gps by using a mapping app then the 'phone stops registering wifi and uses the gps to give a far more accurate timeline.
