Intel X550T 2.5G Not Working

Andrew

@livegrenier ethtool is not persistent, you can add the command to run at startup.

Quoting the readme:

By default, devices based on the Intel(R) Ethernet Controller x550 do not
advertise 2.5 Gbps or 5 Gbps. To have your device advertise these speeds, use
the following:

# ethtool -s <ethX> advertise N

Where N is a combination of the following.
100baseTFull   0x008
1000baseTFull  0x020
2500baseTFull  0x800000000000
5000baseTFull  0x1000000000000
10000baseTFull 0x1000

For example, to turn on all modes:
# ethtool -s <ethX> advertise 0x1800000001028

So, use ethtool -s ethX advertise 0x1800000001028
You may have to restart negotiation after the change ethtool -r ethX

@Andrew unfortunately doesn't sound like a great option long term, you think this will work out of the box?

I'm looking for something with great support that will work for a long time, my current card doesn't sound like this going to be that unfortunately

Andrew

@livegrenier Yes, the i226 should work, but that one is very expensive. Do you need two ports? The single port ones are cheap ($25us).

I have not tested one of the generic dual port i226 cards, I'll order one for testing (about $40us).

If you want an out-of-the-box known supported multi-gig card then you want an AQC107 ($64us, today).

@Andrew I really appreciate your ideas, I like the idea of paying less for just 1 port, you are right I do not need 2 ports.

I'm in Montreal so I have to use amazon.ca, the 10G card you link is not available in Canada but for the same price as the 2.5 dual nic card I can get this one:

https://www.amazon.ca/Port-Gigabit-Ethernet-Network-Card/dp/B07G2DV9K2/ref=sr_1_2?crid=24N7U52FGEOL8&keywords=AQC107&qid=1700951323&sprefix=aqc107%2Caps%2C70&sr=8-2

That should work right? I just don't want to be returning a card every week

Andrew

@livegrenier Looks ok (with full height bracket). You might need to fix the heatsink on that card (check reviews).

The TPlink TX401 looks ok.

livegrenier

@Andrew The TX201 would not work right?

I think it needs special drivers and all of that? no out of the box support from what I can tell...

Andrew

@livegrenier The TP-Link TX201 uses the RTL8125 chipset.

livegrenier

@Andrew thanks, and I see the tx401 has a chipset AQC107, so I'll go with that if you think it's going to work out of the box, I'll probably put this project on hold for a moment, but as soon as I have a confirmation I'll update this post to let everyone know how it went, might take a few weeks but I will.

Thanks for the help

livegrenier

Just wanted to confirm I got that TX401 NIC and it's been working well so far on 2.5G

I have been able to run a script at startup that enables 2.5g on the Intel X550. Here's how :

Create the script that will run at startup

nano /usr/local/bin/x550.sh

Content of x550.sh :

#!/usr/bin/bash

sleep 1m
ethtool -s eth1 advertise 0x1800000001028
echo `date +%F" "%T` "Startup script worked" >> /root/x550.log

Make the script executable :

chmod +x /usr/local/bin/x550.sh

Create the service that runs the script at startup

nano /etc/systemd/system/x550.service

Content of x550.service :

[Unit]

Description=Runs /usr/local/bin/x550.sh

[Service]

ExecStart=/usr/local/bin/x550.sh

[Install]

WantedBy=multi-user.target

Enable the service

systemctl enable x550

Reboot and run this command to see if the link speed is 2.5g

ethtool ethX (replace X with yours)

It should show this result :

You can check the log file of your script located at /root/x550.log
