[Linux] Ubuntu 10.04在x220下找不到ethernet

因為Ubuntu 12.04用不習慣, 只好裝回10.04, 但杯具馬上發生, 安裝完後竟然找不到ethernet

dmesg|grep -in eth

空

沒有網路也沒辦法下載套件,source等, 什麼都沒辦法做, 還好有估到一篇

解決步驟 1. 查詢裝置類型

$ lspci -nn|grep -in eth

5:00:19.0 Ethernet controller [0200]: Intel Corporation Device [8086:1502] (rev 04)

2. 根據vendor id + device id搜尋, 8086是Intel Corporation, 1502是Intel 82579LM Gigabit Network Card

3. 去intel網站下載適合的驅動程式 先搜尋"82579", 再作業系統欄位選擇"Linux", 會得到e1000e-2.5.4.tar.gz

4. 最後就編譯安裝, 重新啟動網路, 搞定, 看到ifconfig有eth0真是太感動了
