Just an amendment since I had to do this again, here are the commands I used:
From my windows computer (where I have the mt7601u.bin file stored):
I had issues putting it anywhere other than the home directory using scp, so I put it there (and then moved it):
First, use scp to copy it from my computer to Raspberry PI (obviously, you need to have a network connection to it):
scp "c:/path/to/mt7601u.bin" "[email protected]:mt7601u.bin"
It will ask for your password.
ssh [email protected]
(it will ask for your password again)
Now, within the Raspberry PI:
sudo mv "~/mt7601u.bin" "../lib/firmware"
This will move your file in the home directory to the correct /lib/firmware directory.
Now:
sudo reboot
And you should be good to go
