Installing 2.5GB nic not working

I am using an ASUS P877Z MB for my new NAS and want to install a faster nic. I installed the new nic and the green light is on but it does not connect to the switch. In Windows the nic would be plug and play but I don’t know what the story is in Truenas core. Do I need a driver? Do I need to assign the nic? Thanks.

Could you share what NIC you’ve installed? The chipset / controller on the NIC will definitely need to be supported by the OS for it to show up. Once you’ve shared that, I’m sure the community can help you :slight_smile:

Assuming it is supported you will need to connect to your 1GbE NIC, access the GUI and configure the 2.5GbE NIC settings, test settings and then save before anything will be enabled. Then you can swap the ethernet cable over to your 2.5GbE NIC and continue from there.

The new nic is a TP-Link TX201.

How can I find out if it’s supported? The nic settings in Truenas only show re0.

Despite the TX201’s RealTek RTL8125 chipset being supported in Linux (according to the datasheet), RealTek chipsets have proven to be problematic with TrueNAS. If configuration options are either missing or dont fix the issue I would suggest it is an incompatibility issue with TrueNAS.

Look for an intel chipset such as the i226 2.5GbE PCIe network card like the one I picked up from ebay for $26. Works great, was detected by intel’s driver update software and has performed as expected.

Thanks. Anyone need a TP-Link 2.5? :slightly_smiling_face:

Can you not return it?

Yes, I can return it, I was kidding, hence the smile.

Sorry i’m crap with sarcasm and the kind :wink:

As @Okedokey has said, those RT8125 chipsets are a pain for this exact reason: very sporadic support or detection :face_with_diagonal_mouth:
There are ways of getting drivers working but it can be complex, tricky, and risky to mess around with kernel drivers and modprobe and all that. Not fun.
Definitely look into used or low-cost Intel chipset or perhaps Marvel AQ chipsets (I’m using these for 10GbE) :+1:t2:

Not supporteed by CORE (OP has not disclosed the version he’s using…), and still somewhat dubious in SCALE, as are 2.5 NICs from any manufacturers.
Refurbished server-grade 10G NICs are cheap.

Thanks, I followed Okedokey’s advice and ordered an i226 card. Should be here tomorrow. I’ll post the results. My next topic will be about VPN’s.

I looked at the 10G fiber but thought that would be overkill. I bought a 2.5GB switch and it has the fiber port but I’m also concerned about compatibility. The 2.5GB should be fine if I can get it working.

New nic is in, configured, and working properly. Thanks
