Hello Ubuntu community,

I'm facing a problem with my WiFi on Ubuntu 23.10 Daily Build (and older ones) and I need some assistance. I recently purchased a brand new Asus SCAR 17 (Ryzen 9) 2023, which is equipped with an MT7922 802.11ax PCI Express Wireless by Mediatek.

Here are the details of the WiFi adapter from the output of the command

sudo lshw -C network:

description: Network controller
product: MT7922 802.11ax PCI Express Wireless Network Adapter
vendor: MEDIATEK Corp.
physical id: 0
bus info: pci@0000:04:00.0

configuration: driver=mt7921e latency=0
resources: irq:116 memory:fca00000-fcafffff memory:fcb00000-fcb07ff

When checking the dmesg log, I found the following information related to the MT7922 WiFi adapter

sudo dmesg | grep mt79:

Although the operating system recognizes the hardware, it does not appear as a wifi device, and I am unable to utilize it. What can i do? i noticed some people around here are having same issues without solution.

Thank you

Ubuntu 23.10 (mantic) doesn't yet exist; it's currently the *development* release Ubuntu *mantic* and remains that until it reaches RC state which isn't expected until after 5 October 2023, and isn't on-topic here until release on 20 April 2023. https://discourse.ubuntu.com/t/mantic-minotaur-release-schedule/34989 Please refer https://askubuntu.com/help/on-topic. For support issues with Ubuntu *mantic* you'll need to use a #ubuntu-next or #ubuntu+1 site (IRC, UF etc)

*daily* builds (all releases) are used for QA-testing, and can include packages that are **not** included on *supported* products (even the released products like *jammy* or 22.04.3 as its not yet been released except as 22.04.2 thus the *daily* can include packages found in *-proposed* that are on the *daily* for QA purposes only). Daily products are not supported on this site.

I used Daily build out of frustration. As title suggested, even LTE or current build have same identical issue

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.
