Ubuntu 23.04 - Dell 9310 - AX201 wifi not working

es flag

Just upgraded my Dell XPS 13 (9310) laptop to 23.04. Now the built-in Intel "Wi-Fi 6 AX201" isn't working. It worked fine with 20.04, 20.10, 21.04, 21.10, 22.04, and 22.10.

Any suggestions? The wifi adapter is shown with lshw -c network. It appears the iwlwifi-compat module crashes on startup.

Performing the reboot after the apt purge now.

Please edit your question to add the result of the terminal command: `sudo dkms status` If, as I suspect, backport-iwlwifi-dkms is installed, remove it: `sudo apt purge backport-iwlwifi-dkms` Reboot and let us hear your result.

@chili555 - I rebooted and the same stacktrace shown in dmesg, trying to reinstall `backport-iwlwifi-dkms` to see if that helps due to the Diff warnings.

With @chili555's identifying of the rabbithole... sudo apt purge linux-modules-iwlwifi-6.2.0-20-generic solved it for me.

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.
