[SOLVED] Is the Realtek RTL8125B-NIC supported?

[Sebastian Apprecht]

I have a small problem with my UNRAID-Server. I replaced the hardware of the hostsystem. Everything expect the NIC works fine. 
Mainboard is an Asus TUF GAMING B550-PLUS with a Realtek RTL8125B 2.5Gb Ethernet-NIC. If I boot just with this NIC I get a random private IP. I have deleted from the boot-Partition the network.cfg and edited this file. With an USB-NIC the network works almost fine but seems to stops working after a random time.

 

Any Ideas what to do? I did not find any information on installing drivers. I don't have any further information on Slackware. I think the RTL8125B-Chip is not fully supported at this point and I need another NIC. Can anyone confirm this issue? Or are there any solutions to this problem.

Install v6.9-beta25, it includes that NIC's driver.

[Sebastian Apprecht]

Thanks a lot for the fast answer - works like a charm

Does the v6.9-beta25 include drivers for Realtek RTL8125 (no "B") correct? 

 

I know this is a stupid question, but I have some serious issues with NIC installation with Unraid and want to be 100% sure this time... 

 

Am about to pull the trigger for this NIC (built with the RTL8125 chipset):

It should.

Shuldn't there be a capability like "<capability id="2500bt-fd" >2,5Gbit/s (full duplex)</capability>"? So the support is there but "only" with 1 GBit/s FD?

Please post diags after booting the beta.

Did not matter for me in this case. But in general that might be an issue.

Oh, I see, you were talking about 2.5GbE support, that I don't know, very few people with 2.5GbE, don't remember anyone with 2.5GbE capability posting about that NIC in the forum.

Yes, on all upcoming consumer/prosumer boards there will be more likely 2.5GbE onboard, so the hassle might be at a later point and you don't need to get 10 GbE SPF+ or (more or less reliable) RJ45 with copper and you just dump it into your 10 GbE Router/Switch. Otherwise I don't know the reason because I would get an RTL8125 (2.5GbE Nic) like @[email protected] - just wanna help

 

For me it was the buying decision for a "cheap" NAS that is somewhat future-proofed.

[JorgeB]

If 2.5GbE is currently not supported by the driver I would expect it would be in the near future, LT is currently using the Realtek provided drivers, so they are the ones that need to implement Linux support.

To anybody trying to purchase the RTL8125 NIC - DON'T.  

 

Unraid recognizes the 8125 NIC as a 1.0 gbe.  

 

I have just purchased a brand new OEM Intel X540-T2 from Ebay for ~$90 USD.   Seems like that NIC works with Unraid.

I'm planning on doing a new amd build and wanted to get some benefit out of my 2.5G switch and was hoping that unraid would support it by now.

 

Can someone confirm if unraid 6.9.x in fact does do 2.5G with one of these nic's:

• Realtek RTL8125-CG  (from ASUS CROSSHAIR VIII HERO)
• Dragon RTL8125AG (from ASRock X570 Phantom Gaming X)

 

[hamzas]

Apologies for posting on this thread that didn't see any updates in a while, just wondering if anyone managed to get 2.5G speeds on 8125 cards?

 

I have RTL8125 both on my unraid tower and my desktop machine (Windows 10), connected together directly using a fairly chunky 1 meter long cat6 cable and no matter what I tweak (mtu settings, parallel threads etc)  I can't get past 1.32Gbits/sec on iperf3:

 

 

MTU is set to 9000 on both the server (unraid tower) and client (my desktop).

 

Any idea what might be wrong?

 

This is using Unraid Version: 6.9.0-rc2.

 

Thanks.

 

UPDATE: After updating the Windows driver for RTL8125 (using "Win10 Auto Installation Program (SId:1152921505692730722) / 10.045 / 2020/12/31" downloaded from here) AND explicitly setting the "Speed & Duplex" setting to "2.5Gbps Full Duplex" in device properties -> Advanced (updating the driver alone didn't do anything), I now get 2.5Gbps speeds on iperf:

 

 

Don't forget to reboot Windows after changing that setting, I was getting a few hundred kbits until I rebooted which was puzzling...

 

Hope this helps folks with the same setup as mine.

What's the current status of the drivers for RTL8125B 2.Gbe, or any other 2.Gbe pcie cards?

 

 

[[email protected]]

Couldn't get it working at high 2.5Gbe.  Only worked at 1.0Gbe for me.  Spent way too much time trying to get it to work.  

 

Don't bother - buy a NIC which is known to be hasslefree.

 

They are not installed in my build. 

[Sebastian Apprecht]

Same here. I also got just 1 GBit out ouf the 2.5 GBit adapter so I switched to a hasslefree 10 GBit one. 
Back in time I switched to the beta version wich invoked some more trouble at other points.

At 2.5 Gbps?  I snagged this one the other day, which looks very similar but is perhaps/probably a different revision, and it would only work at 1.0 Gbps. 

 

https://www.amazon.ca/gp/product/B08VWQFQ5Z/

 

I returned it since it did me no good sitting at 1.0 Gbps.

[Squid]

Mine works perfectly for me @2.5

[_Shorty]

Great, I'll snag one.  Thanks!

[_Shorty]

Well, I'm sorry to say the card arrived and does not work for some reason.  When I power on the box my switch shows that it is connected at 1.0 Gbps and then as the box continues through the boot cycle it eventually stops showing as connected at the switch.  The first card I had would still show connected at the switch at 1.0 Gbps, but would never get a network connection in the OS.  It's all quite puzzling.  Guess I'm stuck with 1.0 Gbps via the motherboard NIC.  Oh well.

 

edit: The card looks different than the first one I had, but also looks different than the one in the picture at the link.  Newer revision yet again, I suppose.  This one's got a heatsink on it.

Perhaps a stupid question.  Does the switch support 2.5Gb/s connections?

 

IF it does, post up the diagnostics file so that we can see what is being detected as Unraid boots.

[_Shorty]

Yeah, my new main/gaming rig I built recently has a 2.5 Gbps NIC in the motherboard.  I also upgraded my internet service to 1.5 Gbps, and that new modem has four ethernet jacks, but one is a 2.5 Gbps jack, so I figured I might as well get a 2.5 Gbps switch and NIC for the unRAID box and speed up transfers between it and my main box.  Now, the unRAID box is headless.  (Doesn't even have a GPU in it.)  I'm not sure how I can get the diagnostics file off of it to take a look, as with the new NIC installed I can't connect to it.  I imagine as soon as I take it out and connect back to the original NIC and fire it up the diagnostics will be overwritten as it is booting up, no?

 

edit: Ah, I see I actually have to run the diagnostics tool to get that info.  I can't do that without being able to connect to it over the network. Doh!

You can, just type 'diagnostics' on the console.
