Most manufacturers just don't give a shit. Had the exact same experience with a well-reviewed Acer laptop a while back, ended up getting rid of it a few months in because of constant annoyances, replaced with a MacBook Air that lasted for many years. A few years back, I got one of the popular Asus NUCs that came without networking drivers installed. I'm guessing those were on the CD that came with it, but not particularly helpful on a PC without a CD drive. The same SKU came with a variety of networking hardware from different manufacturers, without any indication of which combination I had, so trial and error it was. Zero chance non-techy people would get either working on their own.
