Scary warning: 40 Mhz and 20 Mhz coexistence?
So I use my Mac's Wireless Diagnostics WiFi scanner tool to find the best 2.4G and 5G wifi channles to use, then enter my two selected channels into the Wireless Settings page of the Netgear Orbi web...
hi , the 2.4 gig wifi world is saturated with users and so as to ensure that this doesnt continue to happen the wifi alliance set a rule that forces the 2.4 gig down to 20mhz in areas where the 2.4 gig is congested and to avoid further congestion , its also called neighbor friendly wifi
so if you disable this setting and force it to run at 40mhz you are just being rude to your neighbors and pretty much giving them the bird
so you can be nice and leave it enabled and everyone will get a bit of bandwidth without too much congestion or you can be a prick and disable it and say screw you to your neighbors
thats your choice
your older 2.4 gig devices will work regardless of if its running at 20mhz or 40mhz
here is a link to help you understand why its there and what it does

So apparently, on the Advanced Wireless Settings page, there is an option called "Enable 20/40 MHz Coexistence". And the help info at the bottom says:
"Enable 20/40 MHz Coexistence - Disabling this option allows your 2.4GHz wireless to stay in supporting the max speed. Enabling this option may reduce the max speed of your 2.4GHz wireless to the half when there is another wireless network detected in your environment; this is to avoid inteference between wireless networks and to get along with other wireless networks in the environment."
Great. Of course I have some older devices that support only 2.4G, so I guess that means I need to leave this option enabled for them to work, but it will also cripple its max speed. Kinda sucks. That's the whole reason I'm selecting specific channels...to "avoid interference".
I wan't both my 2.4G and 5G Orbi radios active AND running at max speed. What do others recommend for this setting?
