I realize this is more Linux-general than Xubuntu-specific, but any help is
appreciated. Although I've used and administered Linux (servers) for a while,
it's been a long time since I twiddled NIC settings -- and it was on RHEL, not
*ubuntu.
I have an HP 8300 SFF desktop running fully-patched Xubuntu 18.04, connecting at
100 mbs, which I'd like to raise to gig. It's hardwired to my 14-month-old ASUS
RT-AC66U B1 router (which is running at gb). The NIC is capable:
# lshw -C network

Starting with the simplest approach, I set the network settings GUI to 'ignore |
automatic | manual' and rebooted each time. Nothing worked. Then I tried:
# ethtool -s eno1 speed 1000 duplex full autoneg on
...with autoneg on and off, but no luck. After running it, ethtool shows
'unknown speed'. After restarting networking it either doesn't connect or
hangs.
Would this work?
# ethtool -s eno1 advertise 0x020
The reason I ask is because there are typically several ways to do 'x' on *nix
and I'd rather use the most optimal. I'm also not very familiar with ethtool.
Re: persistence -- On *ubuntu I assume the way to make it permanent is by
putting this at the top of /etc/network/interfaces:
sudo ethtool -s eno1 autoneg off speed 1000 duplex full
...or whatever the correct invocation is?
Thanks.
