I have an internal and external wifi. I can access the web with Whonix with the internal wifi OK, However, I cannot with the external wifi. This issue is related to Whonix because if I turn sys-whonix off, and change the VM settings of the Untusted VM to access sys-firewall, I can access the web with the external USB device. So this is not an error in Qubes or an error with my system. Every time with the external USB wifi Tor fails to connect with 5% completed.
Either this is some type of firewall issue or something is not being passed properly between sys-whonix and sys-usb.
