I have a notebook MSI GT72S 6QE Dominator Pro with installed Ubuntu 14.04.3 LTS. This notebook has Atheros Killer E2400 Ethernet and wifi controllers. There are no drivers for they in Ubuntu ISO, so I have to install it manually (as described in this and this). To install these drivers I must have the internet connection, but I can't connect neither via Ethernet nor via WiFI.

Then, I decided to connect notebook via my phone HTC Wildfire S with Android 2.3.5. I connected phone to WiFi and then connect phone with the notebook via usb cable (usb-tethering). Then, I tried to turn on Internet connection:

$ sudo ifconfig usb0 up

but got an error:

SIOCSIFFLAGS: Cannot assign requested address

So, I got the new record in my Network Connections table, I still have no Internet.

enter image description here

How can I connect to the Internet to install all necessary drivers?

If you need some additional information, please write.

    Don't run ifconfig manually, it will mess up the interface. You shouldn't actually need to do anything - just connect the USB, enable tethering on the phone, and NetworkManager will detect a new "Ethernet Network (name of phone)". If it isn't working like this, have a look at dmesg -w when you plug the phone in and turn on tethering - you should see rndis_host usb0 ... also check the output of lsusb

In my experience there is no way to use:

ifconfig usb0 up

By the way, I had the same problem, so I have had just looked around and I have been confronted with a wonderful Android App, which is EasyTether. at its called it is super easy, just follow up the instruction to come up with it. have fun
