I have just installed Ubuntu 16.04. When I try to connect to my ISP server(wired) from my terminal, it's gives a error cannot get hardware address.

The error log is- 2016-07-13 06:09:21 [4354] crclient1.1 Build $Date: 2003/05/01 13:37:30 $ 2016-07-13 06:09:21 [4356] ERROR: ioctl() failed. No such device

I did not get this error, when I was using this same wired internet Ubuntu 14.04.

To connect to the internet, I have to login to my ISP's server with a program called 24 online client

Error message

My hardware address
