Hi there. I'm absolutely blown away with Zorin 16. Everything works and it's super slick, with this one annoying exception - my ethernet seems to be running rather slow.
Going to speedtest.net when booted into windows gives me about 900Mbps download and upload speed, as my internet is gigabit fibre. However, Zorin is strangely giving me 48Mbps down, and 908Mbps up on speedtest.net.
Both the settings GUI and the ethtool command are showing that the link is up at 1Gbps:
[ 0.851049] r8169 0000:04:00.0 enp4s0: renamed from eth0
[ 6.589602] r8169 0000:04:00.0 enp4s0: Link is Down
[ 9.479191] r8169 0000:04:00.0 enp4s0: Link is Up - 1Gbps/Full - flow control rx/tx
[ 9.479202] IPv6: ADDRCONF(NETDEV_CHANGE): enp4s0: link becomes ready
So I'm not entirely sure what else I can do here. IPv6 is disabled and everything seems fine.
What can I look at next to resolve why the downlink is so slow? The device is an r8169, and it is running 1000Mbps, full duplex.
Thanks for the suggestion. I have made the change and restarted, but the results were the same. Just to confirm this is a hard wired gigabit ethernet connection, but worth a go anyhow. Speedtest when running Zorin is still approx 45Mbps.
Okay nice one. Switched to that driver and rebooted. Speedtest.net is now giving me 73 down and 1016 up. A little faster on the downstream, but I'm so confused as to why the upstream is roaring, but not the down.
I tried it without autoneg on the interface, but no change.

Test: recommended downloader programs (You only need one of these):
Perl HTTP::Tiny is the default downloader tool if IO::Socket::SSL is
present. See --help --alt 40-44 options for how to override default
downloader(s) in case of issues.
If dig is installed, it is the default for WAN IP data. Strongly
recommended. Dig is fast and accurate.

dig: -i wlan IP................................................. Present
wget: -i (if no dig); -w,-W; -U................................. Present

Test: recommended Perl modules (Optional):
None of these are strictly required, but if you have them all, you can
eliminate some recommended non Perl programs from the install.
HTTP::Tiny and IO::Socket::SSL must both be present to use as a downloader
option. For json export Cpanel::JSON::XS is preferred over JSON::XS.

Ok, all done with the checks. Have a nice day.
Hi 337harvey. I'm not sure what you mean by this. Why would my router see traffic from this host, on the same MAC and the same IP as being 'from a different' machine? I'm not sure how that is possible. The router just shunts packets around.
If I reboot this host into Windows I get an instant 900Mbps downstream speed. Boot back into Zorin and it becomes 80, and this is endlessly repeatable.
Hmmm Is this driver installed?
I am on my way out the door to drive my son in to work but also please see Harveys post above - a thought that never even occurred to me (the beauty of the forum being a Team Effort).
I can see from the output of dmesg that the new module has been inserted
Running speedtest.net now shows download speed of 884 and upload 908.
It is true, this will need recompilation after every subsequent kernel update, but at least it is not like X11 won't load and being stuck on a text console.
Thanks for the assistance everyone. In this instance, the manufacturers driver seems not to have the issues that the default one has.
