Yes, for sure. 99% of the time, based on personal experience, the person either doesn’t realize the difference or is just incorrectly using the term Cat5 to mean Cat5e. It’s pretty rare you’ll find the former even in older homes (again, my experience based on living in the US). This is why I intentionally used the term Cat5e in my reply. Cat5 was deprecated by Cat5e back 20+ years ago, long before the average US home began getting wired with Ethernet. Further, many (majority?) of Cat5 cables older than 10 years old actually meet the 5e requirements, just weren’t certified specifically.

> Cat5 struggles with 1gbps.

Like with my original point, that depends on the length and the quality of the connections. Inaccurate blanket statements mislead or worse, so I encourage you to avoid it.

1000baseT requires plain old category 5 for distances of up to 100m.

Most plain category 5 out there will have no problem with 2.5gbase-T at 30m and less.

(And, of course, most "cat 5" is actually "cat 5e".
