I use wifiman.com, it’s a Ubiqity website. Fiber is still “up to” speeds. Like other people have stated there are a lot of variables in the signal. But still should be pretty consistent. But unless you have multiple people gaming at the same time you do not need Gigabit speeds. No media take that much speed. 4K movies only need on average 40Mgb.
