Wifi network says 20 MHz (40 MHz Intolerant)

Installing and Using OpenWrt

Hello,

I have 2 Belkin RT3200's setup. I have the 2.4ghz and the 5ghz networks setup using the same SSID. The 2.4GHz is setup as a 40 MHz width. 5Ghz is setup with a 160 MHz width.When I do the channel analysis on one of the devices the other device's radios show up in the list (which I would expect), but it says "20 MHz (40 MHz Intolerant)". Does intolerant mean what I think it means? It can't do 40MHz? The 5Ghz appears correctly.

Looking for any insights you can provide. Thank you in advance.

It just beacons the fact that it found other AP in range during initial channel selection and did not get chance to go with 40MHz, that will be received by nearby AP during automatic channel selection and that will also refrain from 40MHz.
You will get significantly lower throughput albeit very impressive link rate forcing non-standard 40MHz channels.
