You have it anyway in the current configuration.

Er, your 'ifconfig' list says otherwise. At the very least you have a
wired interface called eth0. It's irrelevant to the current problem,
though.

There are multiple ways of doing it. Bridge, NAT, tunnels, you name it.

Because it's the simpliest way to accomplish such connectivity. But
about the only *real* need to use a bridge arises if you need the
outside world to communicate with your VM. As in - you need someone to
establish inbound connections to your VM with the minimal hassle.

Got it.

Just as planned.

Which is clearly shown by this (note NO-CARRIER):

So, disregarding eth0. Do you have wpa_supplicant running? Does wpa_cli
show successful association with your AP?
