Hello everyone... when attempting to install Kali on a separate partition with a USB, I get an error that is getting to be a little frustrating.

When it gets to the network hardware detection i get this error:

"Some of your hardware needs non-free firmware files to operate. The firmware can be downloaded from removable media, such as a USB stick or floppy.

The missing firmware files are: rt2870.bin

If you have such media available now, insert it, and continue."

I DONT have the firmware files downloaded on to my USB, and when I do a search for them online I get three choices between wheezy, jessie, and squeeze?

It would be great if someone could please help me properly locate and install the firmware files... thank you so much!!!
