used as for GUI desktop/ portable admin for my SOHO LAN:

It also has Wi-Fi, which has been switched off for many months (via the
wireless switch on the right side of the laptop). I switched on Wi-Fi
today, booted, logged in, and chose Xfce Panel -> right click
NetworkManager Applet -> Enable Wi-Fi. Wi-Fi does not start.
Powering off, unplugging Ethernet, booting, logging in, and chosing
Xfce Panel -> right click NetworkManager Applet -> Enable Wi-Fi produces
the same failure to start Wi-Fi.
Ethernet and Wi-Fi have both worked in the past; both separately and
simultaneously.
After failing to start Wi-Fi three times, I see:

third attempts left the last two entries shown above.
STFW "debian iwlwifi firmware: failed to load iwl-debug-yoyo.bin (-2)",
I see:
https://forums.debian.net/viewtopic.php?t=149817
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=966218
AIUI the posts indicate that the message "iwlwifi firmware: failed to
load iwl-debug-yoyo.bin (-2)" is a warning only; it did not affect
operation (?) (as of November 2022).
Is anyone else running an Intel(R) Centrino(R) Advanced-N 6205 AGN,
REV=0xB0 Wi-F- adapter?
Has anyone else seen this issue?
Comments or suggestions for gathering information and/or getting Wi-Fi
working?
TIA,
David
