Hi,
I have got a Lenovo L460 with Broadcom brcm4356 Wifi Adapter that I don't get
working on Qubes.
To isolate the problem, I have first installed a debian-9 directly on the
machine and got this after some problems working
(https://www.linuxquestions.org/questions/linux-wireless-networking-41/debian-broadcom-bcm4356-802-11ac-wireless-not-working-4175644801/)
Steps to reproduce:
- Have Qubes 3.2.1 (also tried Qubes 4.0.1-rc2 without success)
- Create NetVM debian-9 based with device:
-- 00:1f.6 Ethernet controller: Intel Corporation l219-LM (rev21)
-- 03:00.0 Network controller: Broadcom Limited BCM4356 802.11ac Wireless
Network Adapter (rev02)
(cable based Ethernet works on qube without flaws)
- install firmware-brcm80211_20180825+dfsg-1_all.deb and add
brcmfmac4356-pcie.txt
- Unload kernel module sudo modprobe -f brcmfmac
- Load kernel module sudo modprobe brcmfmac
- sudo dmesg | less

=> if I install on the same machine debian-9 directly the wifi works
=> if I use qubes debian-9 NetVM I get "SB chip is not supported" even though
device is attached to VM
=> Has anyone an idea/suggestion what I could do to get rid of the "SB chip is
not supported"? I assumed I had the wrong firmware, but why can I use the exact
same *deb package on the same machine successfully if I install debian directly
on the same machine without qubes?
P.S.: I have also tried to create a HVM with debian-9 installer:
- if I install debian on the HVM the X Window gets messed up => black screen
=> need to switch on/off the machine
- if I use live DVD on HVM => I can install package until reboot, run the
modprobe brcmfmac command without error in dmesg, but the Wifi Adapter is not
shown in the Network Manager
Thanks for any help!
