/var/log/console.log included:

% uname -aKU

Probed this afternoon: <https://bsd-hardware.info/?probe=3ad7cec298>.

TIA

Without checking logs: I tried a few things to regain name resolution with Wi-Fi, failed. I resorted to a wired connection. After restarting the OS, I checked /var/log/messages and found these three lines (some redaction): Nov 26 11:02:31 mowa219-gjp4-8570p-freebsd wpa_supplicant[395]: wlan0: CTRL-EVENT-DISCONNECTED bssid=58:⋯ reason=3 locally_generated=1 Nov 26 11:02:34 mowa219-gjp4-8570p-freebsd wpa_supplicant[395]: wlan0: Trying to associate with 58:⋯ (SSID='piano' freq=5180 MHz) Nov 26 11:02:34 mowa219-gjp4-8570p-freebsd wpa_supplicant[395]: ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Can't assign requested address Nov 26 11:02:34 mowa219-gjp4-8570p-freebsd kernel: Nov 26 11:02:34 mowa219-gjp4-8570p-freebsd wpa_supplicant[395]: ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Can't assign requested address Nov 26 11:02:34 mowa219-gjp4-8570p-freebsd kernel: Nov 26 11:02:34 mowa219-gjp4-8570p-freebsd dhclient[1118]: send_packet: No buffer space available Nov 26 11:03:17 mowa219-gjp4-8570p-freebsd kernel: Nov 26 11:02:34 mowa219-gjp4-8570p-freebsd syslogd: last message repeated 1 times FreeBSD mowa219-gjp4-8570p-freebsd 14.0-CURRENT FreeBSD 14.0-CURRENT #25 main-n259004-2c10be9e06d4: Thu Nov  3 00:14:52 GMT 2022 grahamperrin@mowa219-gjp4-8570p-freebsd:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG amd64 1400073 1400073
