Your Internet provider probably has a dynamic IP address (not fixed/static) so every time your router tries to get a new IP address from your provider there's a chance it'll be something different. Then each time you log into FFXIV with a new IP address it'll trigger the "suspicious activity" flag.

To fix this as others have mentioned above, just add a security token to all affected accounts (either a physical one which is a small cost from SE or as a smartphone app (free for Android and iOS). Having a security token on the account not only allows you to have a free teleport location in game (that you can change whenever you want), but it also overrides the IP checking.

Or you could contact your ISP and ask for a static IP address (if they can do that though they'll likely charge for it).
