New Ubuntu 20.04 install doesn't recognize wifi adapter

in flag

Old mobo gave out so bought a new one. Got Ubuntu 20.04 installed on it since that's the USB I had lying around. To update etc I need to be online. I open up settings and it says no wifi adapter detected :(

Full specs:

  • i5-12400
  • 8gbx2 5200MT/s DDR5
  • Z690I Aorus Ultra Lite mobo
  • Samsung 970 EVO Plus SSD 1TB NVMe M.2

Here's the mobo info page: https://www.gigabyte.com/Motherboard/Z690I-AORUS-ULTRA-LITE-rev-10/support#support-dl-bios

I have already flashed BIOS to version 23a which is the latest. I don't see any linux drivers in the download section. Any advice on what to do?

What is Ubuntu 20? There is no such desktop version. Try to boot with 22.04 and check if the wireless device is detected.

Don't forget the *year* products are specialist *snap only* products of the main *year.month* release intended for Cloud or IoT usage, they are smaller thus faster to boot & require less RAM, but are less powerful than the *year.month* server product it comes from, ie. 20 differs to 20.04.

The specifications page in your link says that the wireless is Intel® Wi-Fi 6 AX201. You can verify this with a terminal commad: `lspci -nnk | grep 0280 -A3` This page suggests that it is included in kernel version 5.2 et seq: https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html Perhaps there are informative clues in the log: `sudo modprobe iwlwifi && sudo dmesg | grep iwl` Please edit your question to include the result of these commands.

I was installing Ubuntu 20.04 because that's what I had on hand. After plugging it in via ethernet it still wouldn't work so I reflashed the drive to 22.04 and it worked after that. I have no clue why.

If you were installing 20.04, why not say so, since 20 & 20.04 are different products (20 being the *snap* only version of 20.04, thus cannot perform all functions of 20.04, but the smaller system also has its advantages, esp. for cloud or IoT usage). Ubuntu has reserved the *year* format for *snap* only since 2016. Please correct your question if you're using 20.04 & not 20

Sure thing will do. I didn't know there was a difference like that.

LTS releases of Ubuntu have kernel stack options; ie. GA is the most *stable* and default for Server installs, HWE provides the *enablement stack* so newer systems can get newer '*drivers*' (*drivers* being the common term for what are actually kernel modules; thus the kernel [stack] being used matters!). Your question was devoid of kernel stack details, not even mentioning desktop/server - so we cannot even guess. 20.04 using HWE (5.15) will use the GA stack from 22.04 so you should be able to get 20.04 working too if using GA for 22.04; but you mention only release and not more...
I sit in a Tesla and translated this thread with Ai:

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.
