What problem?

The loopback interface does not need wireless extensions, it is not even a physical interface.
ETH0 does not need wireless extensions, it is the wired interface.

What are you really looking for here?

If you need the name of the WIFI interface, try running

Code:

ip link

and look for the interface that is NOT lo or eth0.

Read the "Question Guidelines" link in my posting signature. Do you expect us to guess as to what version/distro of Linux you're using? What hardware? What wifi adapter? Anything you've done/tried/looked-at??? You've posted something, as wpeckham points out, that is 100% normal, and asked us what the problem is. Loopbacks are internal; eth0 is wired, so it will NEVER have wifi extensions.

Post details and we can try to help.

I assume you need to get a driver for your wireless NIC. It's common with almost every linux distro that some wireless nic driver isn't installed. A few makes are not easy to get working. Some work out of the box.

eth0 usually is an installed ethernet nic.
