Hi,
I just updated my old itx nas (J1800 based) with a new RTL8126 pci-e network card and installed fresh OMV7.
Naturally i disabled built-in lan card in BIOS before install but new card is not recognized. After enabling back built-in card, installation finished without problem.
Using lspci command i can confirm that both Ethernet controllers are present and visible, old one using r8169 kernel driver/module.
Obviously there is a problem with driver/firmware for RTL8126.
Since I'm extremely inexperienced with anything linux based and searching the web did not offer solution, any kind of support would be helpful.
Only thing that i found and could be potentially useful is this post from sth forum (https://forums.servethehome.co…ard-a-quick-review.44718/)
"Initially I tried it with Linux Mint running kernel 6.5. No dice, the network controller is too new for the kernel driver.
Next, Debian 12 with kernel 6.7. Also no dice, same issue.
I grabbed the newest driver from Realtek and ran their autorun.sh script, which quickly compiled the proper driver and got the network card up and running.
Card links at 5gb, and iperf3 to my file server gives consistent 4.70gb/sec with zero retransmissions.
Redid the above steps in Debian 12, and got the same results. So their driver at least works ok up to kernel 6.7"
