I apologize in advance for my rookie question but I seem to be very stuck here.
(I have this question posted elsewhere just FYI)
I recently started learning linux and I'm booting into debian from USB. I'm not sure what I'm doing wrong but I cannot get my wifi up. Regular wired works perfectly.

iwconfig shows no wlan0. No messages about iwlwifi firmware in dmesg. lsmod shows iwlwifi loaded and used by cfg80211. I can modprobe iwlwifi off and on.

Below are some screen shots with some info. Sorry for the ugly picture. I was really trying to figure this out myself but not sure if its going to happen.

Results from:

uname -r; lsmod | grep iwl; dmesg | grep firm; lspci -nnk | grep -iA2 nethttps://i.stack.imgur.com/PZmfj.jpg

It may not be wlan0.

I think Debian has switched to the misleadingly named "Predictable Interface Names" used by SystemD.

What does /sbin/ip link show give you?
