    Ubuntu 21.10 Wifi (Intel WiFi 6 AX200) not working.

    Hello, I'm using 21.10 (actually a beta from a few weeks ago, but it's been updated) and I cant get my wireless card working. Its an intel AX200. I believe that this should be supported on kernel 5.1+. My system can see it, for example

    Code:
    lshw -C network
    <ethernet device>
      *-network 
           description: Network controller 
           product: Wi-Fi 6 AX200 
           vendor: Intel Corporation 
           physical id: 0 
           bus info: pci@0000:04:00.0 
           version: 1a 
           width: 64 bits 
           clock: 33MHz 
           capabilities: pm msi pciexpress msix bus_master cap_list 
           configuration: driver=iwlwifi latency=0 
           resources: irq:24 memory:fc600000-fc603fff
    And I can see it gets the firmware here:
    Code:
    dmesg | grep iwl
    [    4.658835] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) 
    [    4.666305] iwlwifi 0000:04:00.0: api flags index 2 larger than supported by driver 
    [    4.666317] iwlwifi 0000:04:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.37 
    [    4.666523] iwlwifi 0000:04:00.0: loaded firmware version 63.c04f3485.0 cc-a0-63.ucode op_mode iwlmvm 
    [    4.826950] iwlwifi 0000:04:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340
    Any advice is appreciated, as my home internet runs at 1-2mbps on a good day, so I usually use a 5g hotspot to get a faster speed, but that requires wifi obviously.

    When I open the wifi settings (which I have to search for, it doesn't exist when I open settings) it tells me that no wireless adapter has been detected.

    To anyone finding this in the future, my issue was having fast-boot enabled in my windows partition. Turning this off fixed my problem.
