Maybe LinkedIn matched you by geolocation? That would be closely related to sharing the same IP address or Wi-Fi network.

A lot of first pass geolocation is done by IP so the user doesn't have to be asked for permission.

IP geolocation might not have high accuracy to match person https://www.ip2location.com/data-accuracy
