ISPs routinely sell/share geolocation data for fixed infrastructure; there are many factors that could impact why this is more accurate. In a sparesly populated area, using microwave, point-to-point radios? You very well may be the only subscriber on that first hop from your home network, and that first hop is likely in a geolocation database (this is certainly the case for my cousins farm). In a densely populated area? Like a residential tower with 100 units? Your next hop off your home network might be on-prem equipment from your ISP that resides in the telecoms closet in your building, which is also in a geolocation database. There is a broad spectrum of accuracy between these, and it's big business to effectively geolocate users, mostly for advertising, sometimes for compliance, and generally not to the benefit of users :P
