系統未檢測到新的 Intel i350 NIC，但出現在 lspci - 可能的 Intel IGB 問題？

我遇到了作業系統沒有自動檢測到新網卡的問題。我最近購買了一塊 Intel I350 千兆網卡。*我以前購買過這張卡，並且我在其他具有相同作業系統的系統中使用它，沒有任何問題。*這是卡https://ark.intel.com/products/84805/Intel-Ethernet-Server-Adapter-I350-T4V2。

奇怪的是，Windows 檢測到了這張卡，而不是 Oracle Linux、CentOS Live 或 Ubuntu Live。

“nmcli d”輸出

DEVICE  TYPE      STATE         CONNECTION
eno2    ethernet  connected     eno2
eno1    ethernet  disconnected  --
lo      loopback  unmanaged     --

這些是板載適配器。未檢測到 4 個 Intel 的。

“lspci | grep 網路”輸出

b3:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
b3:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
b3:00.2 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
b3:00.3 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)

作業系統似乎至少知道 PCI 卡的存在。

這是“lshw -class network”的輸出

我注意到這裡也檢測到了該卡，但它被列為“UNCLAIMED”。如何讓系統“認領”這張卡？

我曾嘗試使用英特爾網站上列出的驅動程序，但似乎沒有幫助。我也可能做錯了什麼。我對linux驅動程序沒有太多經驗。

任何幫助將不勝感激，

謝謝！

似乎手動更新網卡本身的韌體使該卡對作業系統可見。

這個問題是幾年前的問題，但我有修復的註釋……我做了以下事情：

在目錄 /etc/NetworkManager/conf.d/ 下創建一個名為“90-carrier.conf”的文件

# touch /etc/NetworkManager/conf.d/90-carrier.conf

Modify the file and add the following two lines to it and save your changes:

# vi  /etc/NetworkManager/conf.d/90-carrier.conf

[main]
ignore-carrier=no

Restart the NetworkManager service:

# systemctl restart NetworkManager
