Its looks to be temporary or permanent hardware failure. There's seems to be no detection of wireless adapter in the log you have attached. To check the adapters available and network connectivity that is possible in the system try this command. sudo lshw -C network In my laptop i got the output as below. harish@harish-Lenovo-G500s:~$ sudo lshw -C ...

In a virtual environment the guest will always show as ethernet connection even if the host is using wifi that is because the guest does not see the hosts hardware it is contained within the virtual environment. The only exception to this rule is if you use an usb adapter for wifi then it can been seen by the guest machine.

It sounds like your phone, when acting as your wifi router, is not providing DNS information automatically. lo is your loopback ethernet adapter, the /etc/network/interfaces file is normal.

I seem to have the exact same problem, in fact, I could almost have written the OP. I don't think it is a driver issue because today I installed a wireless card from ThinkPenguin, which changed nothing. When I access the wifi with other devices it works fine. This is likely a software problem.

Use a USB external WiFi adapter until the problem is solved. It should definitely connect. If it does, lets get started. Most probably, the issue is with firmware.

If this is a laptop, check for a wireless switch. You probably have already checked this, but it has caught many people by surprise. It is usually on the side or front edge of your laptop.

As far as I can tell, there is no information at all that is available to suggest the correct driver. I am fairly certain that, based on modaliases, it is not b43/bcma, brcmsmac nor brcmfmac.
