ubuntu16.04不能联网

[xulianpu]

从14.04升级后不能联网了
换回kernel 3.13能联网kernel 4.4不行
dmesg | grep iwl

尝试换用其它版本内核 如 Linux 4.7 (从 http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/ 下载)
或使用 Ubuntu 16.04 LiveCD/LiveUSB 测试。若正常，考虑备份文件后全新安装 16.04

兩者都沒有作用中的驅動 ?
兩者的 physical id 都是 0 ?

沒有載入合適的驅動模組 應該是主要原因

使用内核4.7依然不行，用内核3.13了

驱动都有，用内核3.13是正常的

可以把 内核 3.13 的

一个相似案例 http://www.spinics.net/lists/linux-pci/msg27017.html
最终结果为不了了之

[poloshiao]

kernel 4.4

内核4.7依然不行

測試
1. 先把無線網卡 從 Bios 關閉 （或拔除)
測試看看
product: AR8152 v1.1 Fast Ethernet
行不行

2. 再把有線網卡 從 Bios 關閉 （或拔除)
測試看看
product: Centrino Wireless-N 1000 [Condor Peak]
行不行

3. 這樣可以鎖定有問題的網卡驅動 來解決

关闭测试，问题依旧。。。

[poloshiao]

关闭测试，问题依旧

分開 有線網卡 及 無線網卡 關閉
測試 問題還依舊嗎

那 可能不完全是 網卡驅動的問題

分别关闭，并且在3.13和4.7里分别试，现象和之前是一样的

0. 先把無線網卡關閉 測試有線網卡 自己編譯/安裝驅動

4.4 或 4.7

1. https://wiki.linuxfoundation.org/networking/alx
atl1c provides support for these chipsets:
1969:2060 - AR8152 v1.1 Fast Ethernet

1-1. https://wiki.linuxfoundation.org/networking/alx
Code
For more details refer to the compat-drivers documentation.
https://backports.wiki.kernel.org/

1-2. https://backports.wiki.kernel.org/index.php/Main_Page
The project started since 2007 and was originally known as compat-wireless, evolved to compat-drivers and was recently renamed simply to backports.

1-3. 最近的穩定版

1-6. 安裝方法
https://wiki.linuxfoundation.org/networking/alx
Install
To only compile and install the alx driver you can do:
./scripts/driver-select alx （或 atl1c）
make
sudo make install

2. 安裝後 重開機 如果滿意
可以把
2-1. uname -r
2-2. sudo lshw -numeric -class network

make时报警：compat-drivers by default supports kernels >= 2.6.24, try enabling only one driver though
