To keep that fix after a reboot on Proxmox, a post-up line in /etc/network/interfaces does it. On i40e cards: ethtool --set-priv-flags <nic> flow-director-atr off. ixgbe has no such flag, but turning ntuple filters on (ethtool -K <nic> ntuple on) disables ATR there. Which NIC was it?

it just dumps the output of ethtool out to a file that i can read that later with a different script.

That's the cleaner instrument, thanks. Before-and-after diff is exactly right for a counter that runs from boot. I'll snap ethtool -S on both ends before the next run; if one interface's CRC climbs and the other sits flat, the receiving side owns it. Cable's still my suspect, but now it's data.

Retr tells you frames are dying and leaves out which end. ethtool -S counts CRC errors per interface, so the counter that climbs points at the receiving side. Read it before and after a run and take the difference, since it counts from boot.

from our zine Bite Size Networking!: https://wizardzines.com/zines/bite-size-networking/
### ethtool is for people who need to manage physical networks server, represented by a sad rectangle: why no internet?? smiling stick figure with short curly hair: oops! it would help if you ethernet cable was plugged in! ### `ethtool eth0` (name of network interface) this tells you: - is it even connected? ("link detected") - speed - lots more ### `--show-offload --offload` your network card can do a lot for you! Like computing checksums. This is called "offloading". This lets you see/change configured offloads. ### `--identify INTERFACE` blink the light on the ethernet port. good if you have multiple ports! and cute. (heart) ### `-S INTERFACE` show statistics like bytes sent. works for wifi interfaces too. ### `-s` change speed/duplex/other settings of an interface. `$ ethtool - eth0 speed 100` ### `-i INTERFACE` show firmware info ### `iw dev wlan0 link` ethtool is mostly for Ethernet. To see the speed (and more) of a wireless connection, use iw.

Oh, man, I guess there is no `ethtool` config for WoWLAN. It's all just done in `iw`!

Wish me luck! Trying `sudo iw phy0 wowlan enable magic-packet` and will see how it goes. Catch you on the flip side (maybe)!

Awh, bummer, no Wake on Wireless (WoWLAN / WoW) on Steam Deck. wlan0 reporting only link status on `ethtool`, what a pity.

there's a qualcomm ath11k QCNFA765 in here; pretty shocked there's basically zero support on it?

also weird, `iw list` does show decent WoWLAN support!!

NetworkManager 1.52 was released today as the latest stable version of this popular open-source software for managing network connections inside a Linux-based operating system. Coming five months after **NetworkManager 1.50**, the NetworkManager 1.52 release introduces IPvlan interface support, the ability to manually configure the authentication of LTE’s initial EPS Bearer, support for ethtool FEC (Forward Error Correction) mode, and support for automatically adding routes to DNS servers via the ipv4.routed-dns and ipv6.routed-dns properties. NetworkManager 1.52 also introduces a new ipv4.link-local=fallback property to set an IPv4 link-local address when no other IPv4 is set, as well as new ipv4.shared-dhcp-range and ipv4.shared-dhcp-lease-time properties to allow the customization of the DHCP range and lease time offered by the DHCP server when in shared connection method. On top of that, this release enables the ability to specify DNS servers with a URI-like syntax that supports DNS over TLS (DoT) name servers and adds support for the “IPv6-only preferred” DHCPv4 option (RFC 8925) for indicating that a host supports an IPv6-only mode and is willing to forgo obtaining an IPv4 address if the network provides IPv6 connectivity. Among other noteworthy changes, NetworkManager 1.52 adds support for using the Dnsconfd plugin for the configuration of the system-wide DNS caching resolver, adds support for storing interactive history in $XDG_CACHE_HOME/nmcli-history instead of ~/.nmcli-history, and adds a “shared” method to the IPv6 configuration options in the `nmtui` text-based interface. It also adds support for the initrd-generator to understand the “rd.net.dns” option for configuring global name servers, adds two additional keys “resolve-mode” and “certification-authority” to the global-dns configuration section, adds support for OCI in nm-cloud-setup, removes support for the “dhcpcanon” DHCP client, and removes support for building with Autotools. Several bugs were addressed in this release, including a bug that prevented the activation of bond and bridge’s ports, a bug that prevented the activation of OVS interfaces, an issue with the creation of MTPCP endpoints for IPv4 with DAD and IPv6 tentative addresses, and a bug preventing some VPN routes from being added to the table specified in the ipv4/6.routing-table, which allows the use of policy routing to mitigate TunnelVision attacks. NetworkManager 1.52 is available for download right now from its _GitLab page_ if you fancy compiling it from sources, but I recommend that you wait for it to arrive in the stable software repositories of your GNU/Linux distribution before updating your installations.
