You need to have base-devel and $KERNEL-headers installed to use AUR and DKMS …
This would do it:
sudo pacman -Syu base-devel linux$(uname -r| grep -o -E '[0-9]+' | head -n 2 | sed 'N;s/\n//')-headers
(all that magic code is just nabbing what kernel you run so that command becomes something like sudo pacman -Syu base-devel linux510-headers for example)
Then go ahead and rebuild that DKMS package.
Thanks again @cscs
That worked better this time, no errors on the driver build.
It did say r8169 conflicts and to blacklist (there’s still a blacklist file in modprob.d so I left it).
I rebooted, but still no dice and transferring at 20MB/s
Any other magic tricks?
I hate realtek. And broadcom. And printers for that matter. (cue officespace) 
Maybe try with boot option
pcie_aspm=off
(as above like the IPv6 option)
Yes, like Epson printers - I’ve wanted to Officespace that thing for a long time!
I’ve updated grub as below:
GRUB_CMDLINE_LINUX="ipv6.disable=1 pcie_aspm=off"
Then ran sudo update-grub and rebooted
Tried copying again, still 20MB/s
Done perfectly … but apparently didnt help.
Can I just be double-triple-sure … we are talking about the wired ethernet connection, right ?
Yes the wired ethernet
Maybe …
iw dev enp5s0 set power_save off
Eck… getting to the end of my guessing here.
I copied that into the terminal and it came back:
command failed: Operation not permitted (-1)
Tried it with sudo in front and said:
command failed: No such device (-19)
huh?
iw dev
yes correct
no I mean … please return the output of that command … it should show us what the correct id is … actually let me amend that slightly:
iw dev | grep -v -E 'ssid|addr'
Although if I justtype iw dev it outputs
phy#0
Interface wlp4s0
ifindex 3
wdev 0x1
addr ae:ff:97:11:5b:1a
type managed
txpower 15.00 dBm
multicast TXQ:
qsz-byt qsz-pkt flows drops marks overlmt hashcol tx-bytes tx-packets
0 0 0 0 0 0 0 0 0
Odd. It doesnt even list your ethernet … then again … I guess it is iw. heh. forgive me.
When it output that, I thought it must be the wifi port?
Yeah … used to troubleshooting wireless … iw is for wireless … please check:
ip link
Thanks @cscs
ip link gives:

Hail-Mary:
ethtool -s enp5s0 autoneg off speed 100 duplex full
Secondary thought … boot params:
pcie_aspm=force r8168.aspm=1
(obviously opposite of off above, and should replace)
I tried the first command, but didn’t reboot as I figured it would only reset with a reboot
ethtool -s enp5s0 autoneg off speed 100 duplex full
But it’s made it even slower, to the point I can barely open a network folder! Oops.
Changing autoneg to on puts it back to working again though
Your benchmark is a samba file transfer?
Maybe the network is fine and its only samba, that is slow.
Try iperf to test your speed.
Thanks @Monarc
Correct as that’s what I will generally use for file transfers. As I’ve said previously, it works fine in a Linux Mint install, but not on Manjaro. Just for shits’n’giggles I tried Manjaro Cinnamon just to see if it might have something to do with the desktop environment (as mint used cinnamon) but still slow in that too.
With iperf, am I correct that I need to start it on the server I’m testing?
iperf -s
Then start it on my laptop with Manjaro
iperf -c ip-address
I’ll have to lookup how to start it on my QNAP as I don’t think it has a terminal installed natively. I have tried to connect to it via ssh but doesn’t want to connect for some reason. I’ll have to read up on that a bit more.
