It's not Lenovo. FreeBSD's unstable as of yet iwlwifi[1] driver can use T14-built-in intel AX200/201/210 card but there's still no 5GHz speeds achievable. Personally, I'm waiting for LinuxKPI[2] emulation to allow using Linux drivers for WiFi adapters, like it allows me to use Linux drm-kmod[3] driver for graphics acceleration in Xorg. For now, there's only 802.11n and some very limited support for establishing 802.11ac connections but still not speeds higher than 2.4GHz.

Isn't this because blobs? Edit: More about GPL. Fair enough. The DRM/KPI might mean I can try FB again on my e series thinkpad which died in X unless I used vesa mode.

5GHz and 2.4GHz are not "speeds" except in the most general sense. They are frequency bands. Speeds vary based on the band in use.

  5GHz offers higher speeds than 2.4GHz. FreeBSD can establish a 5GHz connection but not use speeds over those offered by 2.4GHz.

    5 and 2.4 are not the speeds, they are the frequency bands. If you're referring to speeds, then refer to Mbps. On WiFi, MHz is not a "speed".

      Irrespective that 5 and 2.4 are labels, in a service offered over 5 you can achieve higher bandwidth because of the increased channel count and baud rate. The point appears to be that FreeBSD has a model in e.g. TCP which tracks the end-to-end data rate (eg as BBR does) and it has boundary constraints which right now limit it to the horizons acheiveable in 2.4 -Presumably because saturating a wifi link with unrealistic packetrate causes congestion problems and so it paces to share fairly. The model doesn't yet know that 2.4/5/5+ exists: it's modelling 2.4 as what a wifi "IS" I really don't know why FB is constraining achievable data speeds to the 2.4 model but I don't believe the person you are responding to beleives the 5 in 5ghz is what its data rate is. or the alternative, I posit: because it can't drive at 5 yet, it only ever bonds at the 2.4 rates on a 5 system which subsumes the slower datarates in the coding model and uses channels to model 2.4 inside a 5 framework. It's driving at 40 in a 100kph lane, because thats all it knows how to do.

There is also wifi box if you want to use a slightly cursed solution that seems to work well enough. https://github.com/pgj/freebsd-wifibox https://github.com/pgj/freebsd-wifibox
