Ubuntu 24.04无法识别内部网络连接
I recently set up a Linux server and am facing a problem where only the onboard 2.5Gb Realtek Ethernet card is showing up, while the 1Gb Intel chip isn't detected. I've checked the "lspci" list again, but still only the Realtek appears. The attached photos confirm this: the black port corresponds to the 1Gb and the red to the 2.5Gb. The 1Gb port has a light that stays on continuously, which is likely the one causing the issue. I can't reach my server via the 1Gb connection, only through the 2.5Gb link.

Verify the device isn't turned off in the BIOS settings. If you have an extra storage card, you might briefly use Windows on it to check its presence, though complete absence from lspci isn't ideal.
I reviewed the bios, but didn’t find any settings for enabling or disabling Ethernet or LAN ports/chips. I plan to bring in a temporary drive and install Windows to test if both ports can be recognized. I was hoping this wouldn’t be necessary, but unfortunately it seems I’ll have to proceed.
You might also attempt sudo dmesg | grep Intel and sudo dmesg | grep igb to check for any kernel error messages related to NIC initialization failure. It's worth noting I don't anticipate this preventing the display in lspci.
