Wifi 6e fast access point

MT7921K is WiFi6E card that works in OpenWRT.

That being said, there is no way it will support "one or two 2gbps streams to client". WIFI6 or not. Such thing does not exist. That is wired 2.5GbE territory.

Does MT7916 support mesh (802.11s) with 160Mhz width, Did u test mesh between yours PI BPI-R64s and got HE160. I have done everything what u can imagine, still got only HE80.

Hi Abunezar, welcome to the forum!

I'm sorry, no, I did no mesh test. I don't actually like mesh all that much, and don't use it at all.

What country are you in? Are there 160MHz channels free where you live? There aren't in Canada, so 160MHz is hard to test here at all.

Thanks for your reply, finally I found the solution. In 6GHz/160Mhz, wpa_supplicant use different channel plan when create mesh links, it uses the following: this is captured from its source code ( wpa_supplicant.c)

	static const int bw160[] = {
		5955, 6115, 6275, 6435, 6595, 6755, 6915
	};
	struct hostapd_freq_params vht_freq;

so when you do configure mesh in HE160 bandwidth, you have to chose one of the following channel numbers: 1, 33, 65, 97, 129, 161 and 193. not like hostap which uses PSC channel number plan.

That is a failing of OpenWrt right now - it doesn't intelligently parse what channels are open based on the country/band/width you have selected. And if you have selected one that doesn't work, you have to guess why it doesn't work.

Oh, that explains why my WiFi can't be enabled on my WAX206 (WiFi 6), I picked another channel for 160MHz and then it works.
