ubuntu 14.04 挂起后无法联网

Question

升级到了ubuntu 14.04 lts， 系统挂起后恢复就无法连接网络了，重启也不行。

Answer 1

Post network configuration information, network card ID, hardware information and other configurations.

Answer 2

ping gateway
Not working. Check the IP settings
If you can get through
ping 163.com
If it doesn’t work
Set up DNS

There are no restrictions on routing and the hardware is normal. Basically it’s just an IP dns problem...

Answer 3

same problem.

I think this is about the hardware support.

I rollback to 12.04 now.
