WLAN and function keys stopped working, phy0 hard blocked

cn flag

I have a Lenovo Ideapad 3, and have been running single boot KDE Neon (20.04 focal) for years. Yesterday my desktop froze. Upon reboot, I found myself with no touchpad, no function keys (with the exception of the Volume keys that continued to work), and no WLAN.

Except the Function keys, there are no other keys on my laptop that can control hardware.

According to the BIOS, WLAN as well as Function keys are enabled.

I disabled the ideapad_laptop module with modprobe -r and by blacklisting in /etc/modprobe.d/blacklist.conf which briefly got the WLAN working. At this point, I updated my sources and upgraded my packages. Upon reboot, I found that my WLAN was now once again not working, but touchpad is working.

Further experimentation with the ideapad_laptop module yielded no results. Disabling it removes the ideapad_wlan and ideapad_bluetooth entries from rfkill list, leaving hci0 Bluetooth and phy0 WLAN. This has no effect on Bluetooth functionality. As per the title, phy0 is hard blocked. As expected, rfkill unblock all does not change this.

The lshw -c network command tells me that I have an Intel Dual Band Wireless-AC 3165 Plus Bluetooth network controller, and the lspci command tells me that my Kernel module and driver in use is iwlwifi.

I've tried running Arch and Neon live from USB, but phy0 continues to be hard blocked, and no function keys. Any thoughts?

Only Ubuntu and official flavors of Ubuntu ( are on-topic here, refer to where you'll find other SE sites where you question will be welcome if you don't want to use a KDE/Neon forum. *FYI: KDE Neon does share a number of support options common with Kubuntu, alas this is not one of them with Neon off-topic here*

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.
