[SOLVED] Ethernet Randomly Dropping

linux systemd-networkd[3272]: enp14s0: Lost carrier
linux systemd-networkd[3272]: enp14s0: Failed to send DHCP RELEASE, ignoring: Operation not permitted
linux systemd-networkd[3272]: enp14s0: DHCP lease lost
im newer to linux and i cant figure this out, when im using wlan0 its all totally fine but my wifi is shit compared to ethernet so im not just ignoring it
it seems to be fine for around 10 or around 30 minutes each time before it drops

Re: [SOLVED] Ethernet Randomly Dropping

Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

We're not gonna be able to tell you *why* based on data that only shows *that*

I had seen https://bbs.archlinux.org/viewtopic.php?id=304575 and tried to add "pcie_port_pm=off pcie_aspm.policy=performance" to my boot options but seems its not the fix for me. i am in a similar situation to the OP of 304575 because I am on a fresh install where I used archinstall

No conflicting services and you're losing the carrier cold, there's no kernel error etc. and no hints of a parallel OS
Seems power related indeed, test the impact of "pcie_aspm=off pcie_port_pm=off"

Re: [SOLVED] Ethernet Randomly Dropping

I checked my uefi and found out it was being controlled by that as well, I disabled it there and in my boot options now it's all working good.

If anyone sees this post later on, I recommend checking your uefi/bios if adding the boot parameters doesn't fix it.
