System76 Lemur Pro (lemp9)

[qube...@isuldor.com]

First time Qubes user here, setting up a laptop not listed under HCL
(yet).
https://tech-docs.system76.com/models/lemp9/README.html

Installation completed fine, and I used a usb ethernet adapter
to upgrade to kernel-latest. The issue is that the wireless interface
does not appear in the network adapter list like my usb ethernet adapter did:

[isuldor@dom0 ~]$ ip address

Any advice?

I had similar problems with a recent System76 Darter Pro installation
(search this mailing list for "Guide to installing Qubes on System76
Darter Pro").

The wifi card that comes installed in a Darter Pro (Intel Wireless-AC
9560) has compatibility problems with Xen+Qubes. I replaced it with a
similar model (Intel Wireless-AC 9260) which worked fine.

You may have the same model wireless card in your Lemur Pro. Searching
dmesg for entries related to iwlwifi should give you the model number of
your card if you have no other way of finding it:

$ sudo dmesg | grep iwlwifi
