New NIC has broken system and Apps

I just added a 2.5G Nic to my set up as my motherboard only supported 1G.
Truenas sees the new NIC and can use it, but Plex won’t work with it.
Initially I thought it needs to be reinstalled to see it, so I looked in the catalog and there weren’t any apps. Truenas wouldn’t refresh the list either.
If I plug in the old port, everything comes back.

As for transferring via SMB, well initially it was fine and worked as expected, but the next day, everything reverted back to 1G. I checked the Logs and it confirmed only the 1G connection is being used.

LSPCI confirms it is still there and visable to the system, and I can see it under the network tab.

How do I unbind the 1G connection so Truenas and my apps work exclusively with the new NIC?

IP address for the onboard NIC is 192.168.0.174/24, and the new one is 192.168.0.175/24

Is the second subnet mask really 25? If so, I wonder why. Otherwise, you shouldn’t use IPs from the same subnet for different NICs.

You can try to remove IP from the 1G nic and set it for the 2.5G nic.

Sorry, it’s 24 like the original

I just attempted to remove the 1G NIC IP, and swapped it to the 2.5, but when I tested it, SMB used the 1G still

Just noticed this in the alerts

Dismiss.

It goes away as soon as I reconnect the 1G.

Just in case – did you press apply changes button after “transferring” the IP?

7

I did, it went into Test mode for about 30 seconds.

If you don’t press anything during the test mode it will fallback to the previous setting. You explicitly need to save the configuration in the dialogue window that appears, to show that you still have access.

Since you’re having trouble with added hardware, perhaps you would be so kind as to say what exact hardware you added? “a 2.5G Nic” is painfully devoid of detail. It could also be helpful to see the sudo lspci -vvv output related to the hardware in question.

Maybe a full screenshot of your TrueNAS Network tab would also be helpful.
