[12:29] <beh>  Hello,   anyone able to help me diagnose a problem with NetworkManager in noble?     (iwlist scanning shows network interface working;   NetworkManager says "wifi unavailable" and so I can't connect via wifi)
[12:29] <beh> nmtui does not show the wifi interface (wlp4s0) in the devices list when I try to activate a connection...  How can I make it aware of that interface?
[12:29] <beh> wifi card is intel8265 (in Thinkpad T570)
[13:52] <tomreyn> beh: maybe it's disabled? "rfkill" should know
[14:41] <beh> $ sudo rfkill list
[14:41] <beh> 0: tpacpi_bluetooth_sw: Bluetooth
[14:41] <beh> 	Soft blocked: no
[14:41] <beh> 	Hard blocked: no
[14:41] <beh> 1: tpacpi_wwan_sw: Wireless WAN
[14:41] <beh> 	Soft blocked: no
[14:43] <beh> Nothing disabled ...  -> https://dpaste.com/726PMNDX2
[15:45] <tomreyn> can you share a fully dmesg, or at least anything regarding initialization and renaming of the wireless interfaces and the usb port it is assigned to?
[15:55] <beh> https://dpaste.com/BJG8MAHFV
[16:21] <tomreyn> beh: remove or upgrade virtualbox (probably unrelated, but spams your dmesg with UBSAN errors). Uninstall the 'wl' module (the proprietary Broadcom wireless LAN driver aka broadcom-sta).
[16:38] <beh> https://dpaste.com/7KB8BR5VV   (after removing virtualbox, wl... ...following another reboot... -- NetworkManager still says "wifi unavailable")
[16:48] <tomreyn> beh: so nmcli does not list wlp4s0 ?
[16:48] <beh> ... it does show it this time:
[16:49] <beh> https://dpaste.com/7KB8BR5VV
[16:49] <beh> wlp4s0: unavailable
[16:49] <tomreyn> same paste as above (dmesg)
[16:49] <beh> (ignore dpaste - that was the previous link) -- nmcli says it's unavailable...
[16:49] <tomreyn> does it say more than that?
[16:50] <beh> yeah, sorry - hadn't copied the line yet and just re-pasted - my bad...)
[16:50] <beh> full nmcli output: https://dpaste.com/9S8JEXK9N
[16:53] <beh> nmcli device output:  https://dpaste.com/8ZLGSLX66
[16:57] <tomreyn> beh: hmm, i'm not seeing anything wrong other than it being unavailable to nmcli. are you dual booting with windows and using fast startup there by chance?
[16:58] <beh> no - single booting only...   It's bad enough to have to use windows at the office... ;-)
[17:00] <tomreyn> does "iwlist scan" list APs?
[17:03] <beh> It does...   -->   https://dpaste.com/EYYUJ43Q2
[17:05] <beh> also added iwconfig output for the device...
[17:06] <tomreyn> and rfkill still doesn't say its disabled?
[17:06] <tomreyn> and you still cant configure it in network manager?
[17:07] <beh> rfkill output still unchanged - nothing shown as blocked...
[17:10] <beh> https://dpaste.com/BEZYQKUH9 -- nmtui doesn't show the wifi interface...
[17:11] <tomreyn> you scrolled down, too?
[17:12] <tomreyn> i'm a bit puzzled there, not sure how to proceed. maybe disabling power saving might work
[17:12] <beh> ...you see the 3 blank lines at the bottom...?   The window was tall enough to show the entire list - with 12 empty lines at the bottom...  nothing else there...
[17:14] <beh> disable power saving - where do I do that?   (apart from the GUI config, switching from "Balanced" to "Performance"?)
[17:15] <tomreyn> i mean wireless power saving, it's a setting in a NM configuration file
[17:16] <tomreyn> somewhere in here, i think /etc/NetworkManager/conf.d/
[17:16] <tomreyn> wifi.powersave defaults to 3, set it to 2 to disable
[17:16] <beh> currently at wifi.powersave = 3
[17:19] <beh_> changed to 2 in conf.d/default-wifi-powersave-on.conf ; restarted NetworkManager - no change
[17:29] <tomreyn> :-/
[17:31] <beh_> wifi used to work on this machine - but at home I'm mostly using wired ethernet - just staying over Christmas with the in-laws at the moment - no wired connection here... :-(
[17:32] <beh_> @tomreyn:  Thank you for attempting to help, even if we haven't figured out the solution yet...
[17:33] <tomreyn> beh_: got a mobile phone you can tether through?
[17:34] <beh_> That's what I'm doing at the moment...   But that connection isn't very fast here...  (ok - on the plus side - it doesn't eat up my roaming allowance that quickly that way... ;-)
[17:39] <tomreyn> hehe. good luck
