First time Qubes user here, setting up a laptop not listed under HCL
(yet).
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
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
...
[user@sys-net ~]$ ip address
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
...
2: vif5.0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 32
...
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
