ubuntu16.04不能联网

[poloshiao]

try enabling only one driver though

試試每次只啟動一個驅動

try enabling only one driver though

試試每次只啟動一個驅動

我在bios里已经disable wlan，还是我理解错了，请详细一些

[poloshiao]

我在bios里已经disable wlan

這是 一次一個網卡 不是 一次一個驅動

目前 一次一個驅動 是針對有線網卡

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

表示 你在 make 以前 就應該做好 一次一個驅動

詳見
https://wiki.linuxfoundation.org/networking/alx
./scripts/driver-select alx
我沒試過這裡是否需要指定 atl1c ?
你試試

另外 不知道 你下載時 有沒有 指定 版本號 例如 4.2.6-1 ？

backports-4.2.6-1 signed

vickycq, 您好，我是刚刚那个发帖说不能没有wifi按钮，双系统，无法联网的用户。刚刚的测试结果发不上去不知道为什么，我给您私信一下吧。

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

重新安装后ok了
