wlo1 for Intel Wi-Fi 6E AX210 missing

I have installed Ubuntu (Mate) 20.04.3 LTS on a Dell Precision 7760 with an Intel Wi-Fi 6E AX210 module. But right from the beginning the Wi-Fi does seem to work (even during the installation):

When I run sudo nmcli device, I get:

DEVICE     TYPE      STATE      CONNECTION         
enp0s31f6  ethernet  connected  Wired connection 1 
lo         loopback  unmanaged  --

So apparently the wlo1 or its equivalent is missing.

According to wireless.wiki.kernel.org the 6E AX210 is supported from Kernel version 5.10 on. I am running 5.11.0-46-generic, so this should be fine, right?

Following this guide by Dell I ran sudo lshw -c network and got:

 *-network                 
   description: Network controller
   product: Intel Corporation
   vendor: Intel Corporation
   physical id: 0
   bus info: pci@0000:93:00.0
   version: 1a
   width: 64 bits
   clock: 33MHz
   capabilities: pm msi pciexpress msix bus_master cap_list
   configuration: driver=iwlwifi latency=0
   resources: irq:17 memory:b1200000-b1203fff

I also ran lspci and got:

93:00.0 Network controller [0280]: Intel Corporation Device [8086:2725] (rev 1a)
    Subsystem: Intel Corporation Device [8086:4020]
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

For both these cases the Dell guide suggestes to "reinstall the device drivers". But this confuses me. I thought the drivers were embedded in the Kernel. So how am I supposed to "reinstall" them?

Update

OK, sorry for not having found this before. Turns out my issue is a duplicate of Intel Wifi 5 AX210 - WiFi not working after Update and Ubuntu 20.04 - No WiFi adapter found

I.e. I am suffering from this bug: https://bugzilla.kernel.org/show_bug.cgi?id=212371

Renaming this file fixed it for me!

sudo mv /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm  /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.bak

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
