No network connection v2

[menthols]

Today installed Qubes 3rd release, but no network connection. Spent hours trying to fix it, but to no avail. Network card is recognized. I have two cables connected, no WiFi. I try to put qubes on Dell poweredge, Intel Xeon e3, 8 GB RAM, Broadcom NetXtreme Gigabit Ethernet PCIe, two 1 TB harddrives. I used option "Test and install" at installation, no error message. I have choosed both harddisks at install, hope there is someway to configure the soft raid. Before tried to install other Linux flavors before (Debian-8 and Fedora-23) and none of them had any trouble connecting to the internet immediately (updates downloaded during install). Maybe need to activate some more PCI devices. What's the best I can do? Wait for the next release? Buy another machine? ;-)

Opened netvm terminal and checked the following things:

1. Does 'lspci' list your network adapter?
Yes, i've tried both debian-8 and fedora-23 both list the network cards.

2. Do you have interface detected (does 'ifconfig -a' contains en* device)?
No, none of them detect the interface using ifconfig.

3. Does kernel messages ('dmesg') contains some errors regarding network
device initialization?
No, there is no message regarding network at all.

4. Check if linux-firmware package is installed (rpm -q linux-firmware).
Yes it is installed.

Ethernet controller: Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe

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?

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.

Hello babel,

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

[cooloutac]

are you able to load them manually with modprobe?

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.
