If I click the link I gave it takes me to a page where I can set my language preference- it may be that the default is what it thinks is your location.
But it uses cookies it finds on my machine, so it may not take you to the same place. Any problem with deleting any Google-based cookies you have and trying my link again?

A level playing field is level in both directions.
But you say here that your phone is OK on the mobile signal, which probably is giving a different location, and if your language preference hasn't been explicitly set on any of the other devices they'll likely be using the default when you connect via your ISP.
It seems to make sense to me, whether it's correct is another matter entirely!
