A lot of low end consumer devices don't. For example the PS Vita supports N but not 5GHz, nor do most kindles until the latest Paperwhite. It was also super common for cheap $400 laptops in 2011 to have N but not 5Ghz support.

I believe Nintendo didn’t support it until the Switch, surprisingly - the WiiU was 2.4 only.

Not for the internet but Wii U uses 5GHz for streaming to the gamepad.
