Can't get ethernet working on fresh install with BCM57788 chipset.

I've had a fair few issues with getting the network working, but eventually I had it working on the install USB by following the wiki and using

modprobe -r tg3; modprobe broadcom; modprobe tg3

However, now that I've switched to my main drive to boot this is not working anymore.

I've checked dmesg and all seems fine there. Editing /etc/mkinitcpio.conf as suggested in the wiki also does not work. Similarly, making a /etc/modprobe.d/broadcom.conf did not help either.

Any ideas?

lspci -k
ip a
sudo journalctl -b > /tmp/journal.txt # upload that file somewhere

Re: Can't get ethernet working on fresh install with BCM57788 chipset.

Thanks for the reply. I've uploaded the journalctl here: https://file.io/8zxzIDWvZHUu

The relevant part of the lspci shows:

03:00.0 Ethernet controller: Broadcom Inc. and subsidiaries NetLink BCM57788 Gigabit Ethernet PCIe (rev01)
Subsystem: Dell XPS 8300
Kernel driver in use: tg3
Kernel modules: tg3

And the ip a shows

 
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisk noqueue state UNKNOWN group default qlen 1000
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
          valid_lft forever preferred_lft forever
     inet6 ::1/28 scope host
          valid_lft forever preferred_lft forever
2: enp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
     link/ether (my mac address) brd ff:ff:ff:ff:ff:ff

The module is loaded and assigned and you've a NIC - but no lease.
The file.io link is unfortunately now 404 - use eg. 0x0.st and in any event please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Re: Can't get ethernet working on fresh install with BCM57788 chipset.

The output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

was

getty@tty1.service          | getty.target.wants
p11-kit-server.socket       | sockets.taret.wants
remote-fs.target            | multi-user.target.wants 

Sorry about the file.io link. The new upload is here: http://0x0.st/HXWY.txt

Which network management software did you install/configure?
