[qubes-users] Re: No network connection v2

[Robert Horvath]

Solved! You have to enable permissive mode for the cards pci addresses. *It 
works with qubes 4.0 and up*. For older versions below refer to this google 
group.  Steps:
0. Turn off sys-net.
1. Go to sys-net's Qubes Settigs in Qubes Manager.
2. Chose "Devices" tab.
3. Remove all entries for network card from qube that are associated to 
qube. (Remember all the PCI addresses)
4. In dom0 terminal type:
*qvm-pci attach --persistent --option permissive=true sys-net dom0:e1_00.1*
(Substitute your own cards pci address you remember from step 3. for  
*e1_00.1* ! Note the underscore!!!)
5. Repeat step 4 for all pci addresses of your card.
6. Done.

[qubes-users] Re: No network connection

[andreazimbardo21]

Hello I know it's been 5 years since this thread started but apple hasn't 
changed and problems are still the same.

I have MB air 2017 with broadcom bcm4360, i've read a lot on how to solve 
this wifi problem but i got so many different info that i can't follow a 
single guide.

Honestly i'm not the best in using the terminal but i can go through it.

I'd appreciate if someone could write a step by step guide in order to get 
this  wifi working.

Thank you all for yoru help

I am having the same issue with Kaby Lake NUC. Tried debian netvm no luck. 
Manual install of driver from Intel, no luck thus far. Per advice from Qubes 
Team I am trying Fed 25 and debian stretch next. I will pass along if I have 
any luck.

Hello babel,

my solution was to buy an additional PCIe netcard and use it :)

Same here on a NUC7i3bn...
check 
lspci -nnk
which was shoowing me that the kernel modules for both the ethernet port 
(i219-v intel gigabit ethernet controller) and the 8265 wireless module were 
not loading.  
Sorry to disappoint you, but I still haven't found a solution.  If you have the 
same problem and find a solution, please let me know.

what do you mean by no network?  Can you manually connect in network manager? 
DNS internet problem?  is network card not recognized in sys-net at all?

Hmm.  
So for some reason, I'm loading the wrong kernel modules, or not at all.  


I tried shutting down the netvm as found here.. 
https://www.qubes-os.org/doc/assigning-devices/ 

Then bringing it back to dom0

echo : > /sys/bus/pci/drivers/pciback/unbind
MODALIAS=`cat /sys/bus/pci/devices/:/modalias`

alone, cat brings a pci-value.  Thanks to this thread 
https://groups.google.com/forum/#!topic/qubes-users/LqhHWJ6GZZU
I figured out to just assign to pci next, but..
the link happens to be unassigned at kernel, because the next command..
MOD=`modprobe -R $MODALIAS | head -n 1`

modprobe: FATAL: Module pci:v00. not found in directory 
/lib/modules/4.4.14-11.pvops.qub...

So I thought I would get clever, but you can't modify anything within 
/sys/bus/pci/devices/\:00../ folder as far as I can tell.  
Also, just adding an alias to the /lib/modules/kernel_version/modules.alias 
doesn't work, so I'm stumped here.  

echo :00:xx.x > /sys/bus/pci/drivers/e1000e/bind
gives me 
-bash: echo: write error: No such device. (even after I add an alias for the 
pci:xxx to /.../modules.alias

If anyone has some insight it would be valuable.
