That's what must be happening here, there are plenty of APs around for

Hmm, this sounds unlikely for my case. APs and my laptop didn't move,
yet my laptop is doing this very frequently.

This doesn't work for me every time. Sometimes, it seems to, sometimes
not. Very weird.

Nice to hear! Every now and then, I'll think about redoing it completely
and adapting it more to the current situation, where profile changes
don't just happen at boot and resume, but much more dynamically. But
then of course real life intervenes and I feel like I won't have enough
time even before I started doing anything...
