Lack of wireless connection: Ubuntu 22.04.2 and Asus pce-ac88

I'm using Ubuntu for over the year and my WiFi worked correctly. Today, when I turned on my PC, there wasn't any wireless connection at all (I didn't change anything or install some new software). I'm using Asus pce-ac88 and it works correctly on second OS (windows 10). I was using Ubuntu 20.04 at that time.

Right now I'm working on Ethernet cable and I updated Ubuntu on 22.04, but still no WiFi. I also work on Ubuntu with dual boot if it matters (Windows 10).

Any advices what can i do except reinstalling Ubuntu?

EDIT:

sudo dmesg | grep brcm

Please edit your question to show the result of the terminal command: `sudo dmesg | grep brcm` Welcome to Ask Ubuntu.

Please see: https://www.reddit.com/r/archlinux/comments/104pqv9/no_wifi_since_kernel_update_yesterday/ The logs shows the exact same error; *brcmf_pcie_init_ringbuffers: invalid max_flowrings(264)*. I believe that a kernel update brought about the error. Can you boot into an earlier kernel at the GRUB menu and does the wireless work there?

I used earlier version (5.15.0-67 instead of 5.15.0-69) and it works!

I suggest that you stick with 5.15.0-67 and file a bug report: https://help.ubuntu.com/community/ReportingBugs

When you booted into an earlier kernel version; specifically 5.15.0-67, the wireless works as expected.

I recommend that you stay on -67 and file a bug report: https://help.ubuntu.com/community/ReportingBugs

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.
