That's funny. To me (mid-40s), the "glory days" of the internet were pre-iPhone, around 1997-2005 or so. Sure, speeds were lower, but that was ok for the time. And sure, everyone didn't have always-on internet access wherever they were, but I think that was mostly a good thing.

I expect if we were to ask a 50 or 60 year old when the internet's glory days were, they'd go even farther back in time.
