This bug is still very much a thing. A quick search will show plenty of recentish talk on forums of other distros.
On my laptop it affects both 20 LTS and the latest 22.10. Have tried everything. Disabling wifi power management. Limiting the band to 2.4khz (supposedly more stable). Upgrading the linux-firmware package (obviously). Switching the firmware files with versions from previous releases. Switching kernels. Once or twice I have managed a month or so of stability (perhaps something special about the LAN). Other times it crashes multiple times per day. Nothing fixes it. Before Ubuntu 20 wifi on my machine worked perfectly. Since then it has not. Very frustrating indeed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1882968 Title: ath10k_pci failed to wake target for write32 Status in linux package in Ubuntu: Expired Bug description: Wifi card stopped working.
