macOS 26.2 update enables 160MHz channels on 5GHz Wi-Fi networks

Honestly, this only really helps people in rural areas. The vast majority of urban 5GHz implementations are at 80MHz - 6GHz does allow for 160MHz channelization, but at 320MHz the attenuation is so great that most homes will require multiple APs to actually hit appropriate MCS indexes.

Fot at home, I tend to stick with 2.4 GHz. It is slower, but with a <100 Mbit uplink to the internet, local speed does not matter. 2.4 does just work better with less APs and thicker walls.

This also only works if you're not living in an apartment building. Even then, there's Bluetooth and other things that don't share spectrum nicely with 802.11.

I have at least 10 neighbours on each 2.4GHz channel.

That's why it's been normalized to buy five of those mesh WiFi routers and shove them all over your house, everybody's signal be damned.

Having lots of lower powered routers is actually better for interference.

MacOS won't roam properly unless the signal from the connected AP drops below -75db, so cranking the power on all your APs will give you worse performance if you move around.

That's only on non-steered roaming though, right? I believe Apple devices have long supported AP/network-side steering.

Since most devices these days only transmit as strongly as they need to, this is actually great for spectrum sharing.
