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

- ggm 3y agoIrrespective 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.
