Arch Linux Intel AX201 wifi 6 找不到6Ghz网络

Question

I have a system76 oryx pro with an Intel AX201 wifi 6 running arch linux kde plasma with the iwlwifi driver. Netowrk Manager has no problem seeing and connecting to the 2.4Ghz and 5Ghz network from my Linksys Hydra Pro AXE6600 Wi-Fi 6E Tri-Band Router but the 6Ghz isn't showing up at all. How can I connect to the faster 6Ghz band?

Answer 1

This is not an answer.

I have the same problem. I have a HP Windows 11 laptop that has the Intel WiFi 6 AX 201 and a Linksys Hydra Pro 6E.

The HP laptop cannot even see the 6 GHz band broadcasting.

I have been asking Linksys Customer Service about it for the past 13 days and it seems they do not have a good answer on how to make it work.

Yesterday, I asked again, but I got a reply:

Hi, dantesan. The 6Ghz band only supports the WPA3 encryption type. It means that only the WiFi 6E supported devices can detect and connect to this band. We encourage you to check with the laptop's manufacturer if they have an updated driver that will provide support or fix/enhance issues for Wi-Fi 6E.

I already followed this link and updated my driver:

It is still not seen.

I added the 6Ghz band into Manage Known Networks and checked 'Connect to it even if it is not broadcasting'. Then I will be able to see it in the list of WiFis and when I connect to it, I will get:

Can't connect to this network

Answer 2

The Intel WiFi 6 AX201 can only connect to the WiFi 2.4 Ghz and 5 Ghz bands. Please see:

Just like you, I should have selected Intel WiFi 6 AX210 or higher which can connect to the 6 Ghz band:

Anyway, the 5 Ghz band of the 201AX can use the 160 Mhz channel although it is just not as stable as the 6 Ghz band.
