We have recently purchased 24 computer of HP Prodesk 400 G7 for our lab, we have installed Ubuntu 20.04 LTS and Ubuntu 21.10 through bootable USB drive. But it is showing that No Wifi Adapter found. We have tried several solutions, but none have worked for me. I have used following terminal commands to see the network devices attached:

$ lshw -c network

Could you explain why the solution in the post you linked to was "all in vain"? Were you receiving error messages? If so, what were the exact messages? The AX201 does not seem to be in your `lspci` output. Do you see it if you run `sudo lspci` or `sudo lsusb` without any filters?

I have tried with `sudo` but the output was same with no network controller i.e. `AX201` I was landed on the mentioned solution because i have read the specification of our minitower system and there it was mentioned that the wifi chipset that is embedded is `intel wifi AX201` and then i molded my search query accordingly and find that solution but no hardware detected.

Based on the information you've provided, I see zero evidence of a wireless network device in your computer. Silly question, but do you have a place for network antennas anywhere on the back of your HP cases?

@matigob The specs do indeed mention either an Intel AX201 (vPro or non vPro, whatever this means) or Realtek RTL8822CE (2x2 or 1x1 variants) and not as optional components. I would check UEFI just in case as it may came disabled by default.

Are you sure you bought the model that has wifi? The product page shows wifi as an option

Sorry for late reply, i have examined the motherboard properly, and found that there is not hardware available inside the minitower box, while company keep claiming there is wifi hardware installed. Hence concluded there was no wifi in this model only Ethernet.

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.
