One of the linksys routers that was advertised to support it, but the radio firmware was not officially supported and I had a lot of wireless connection issues so I replaced it.
DD-WRT has a license agreement and NDA in place with Broadcom that allow usage of better, proprietary, closed source wireless drivers (binary blobs) which they are not allowed to redistribute freely.
Broadcom has not released any FOSS drivers. Broadcom doesn’t support open-source much at all.
Basically bcm doesn’t want people to use opensource.

Info from official openwrt website.

It says in bold red not supported. Not surprising for Broadcom.

Seems what you said. Broadcom wifi chip code.

Yeah it was some bullshit because the router is advertised as running WRT and there is an image for it, but that stupid radio chip fucked it all up.
