XB7 - can't set Wifi 160 MHz option. S22 Ultra supports this. Please fix it !

I recently upgraded to the XB7 . I have the xFi unlimited package.

On the wired side, all is good I get about 1400 Mbps down, as I'm using N-base T equipment (10 Gbps LAN) and the XB7 has a 2.5 Gbps LAN port.

Well, the upload is still capped at a ridiculous 40 Mbps, so all this is not good there still ...

On the Wifi side, sadly, things are not so rosy. When I configure the Wifi 5 GHz connection, I see :

The Channel bandwidth is set to 20/40/80  . There is a 20/40/80/160 option, but it is not possible to manually select it !

The Xfi web site does not have this option available either. I followed the instructions at https://www.xfinity.com/support/articles/change-wifi-mode-admin-tool-xfinity-xfi , but unfortunately, these instructions are wrong. I can't select the band or Wifi mode.

I live on a hill with neighbors far apart, so I should be able to use 160 with no problem. In fact, I already have 4 Unifi Wifi 5 APs all setup at 160 that work perfectly fine. But they are Wifi 5, so they cap at slightly lower speeds. They also have only 1 Gbps ethernet ports rather than 2.5 Gbps, so they can't go any faster than gigabit. The actual speed I get from them from my Note 20 Ultra is about 500 - 600 Mbps.

When connecting with my Note 20 Ultra to the XB7 Wifi 6 at 80 Mhz, I get about 800 Mbps. This is better, but still not what it would be at 160 MHz.

How can I force the XB7 to use 160 MHz on the 5 GHz band ?

Same question about forcing 20/40 MHz on the 2.4 GHz band.
