XB7 - STILL no Wifi 160 MHz option S22 Ultra supports this. Please fix this !
This is a followup to https://forums.xfinity.com/conversations/your-home-network/xb7-no-wifi-160-mhz-option-please-fix-this/60f0de9bf692cf395dfa8446 .
The thread was incorrectly closed without any solution. To recap :
I 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 :
Wi-Fi Mode, Security Mode, Channel Selection, Channel Mode, and Channel Bandwidth are being managed automatically to help optimize your home Wi-Fi network and improve Wi-Fi coverage. To edit your Wi-Fi Network Name & Network password, please download the Xfinity xFi app or visit xfinity.com/myxfi.
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 in the admin UI !
The Xfi web site does not have this option available either.
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 5 Unifi Wifi 5 APs all setup at 160 that work. Channel scans show no interference. 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.
When connecting with my S22 Ultra to the XB7 Wifi 6 at 80 Mhz, I get about 800 Mbps. This is not bad, but still not as good as it should be at 160 MHz. The S22 Ultra specifically supports HE160 mode, per its specs at https://www.samsung.com/global/galaxy/galaxy-s22/specs/ .
How can I force the XB7 to use 160 MHz on the 5 GHz band ?
