Unable to connect to WiFi with new usb dongle network adapter

Here is the output when my new dongle is plugged in

Also I have another problem:
When I start my PC before grub loads I get the following error:

error: ../../grub-core/disk/efi/efidisk.c:615:failure reading sector exfefc from `hd0`

It disappears and proceeds to the usual grub boot selection window once I unplug my dongle.
