Ok another atempt
With the VM image you had before downloading this one, do this:
Boot the vm normally and press ALT+F1
user: root password: notforall
Type this
nano /etc/udev/rules.d/70-persistent-net.rules
and go to the second line, and in the very end of it change wlan1 to wlan0
press ctrl+x and press Y to save the changes
after type poweroff
(all this with the wlan card plugged in)
Re launch the VM and tell what happens please![]()
OK, so now the 3DS connects with full signal and the VM outputs this
Also there's a green light flashing on the 3DS after some time, so I guess it works now?
EDIT: Yeah definitely works. Just checked my notifications and the 3DS has fetched 15 people on my Pokemon Y. Thanks a lot
