All,
sorry for picking up this quite old post, but was there a solution found?
I got the exact same problem with my Nano + Kali here.
Once I connect the Nano, it will overlay the existing WiFi connection on wlan0. I can then access the Dashboard via the browser, but not the internet.
If I add the default route and delete the one that does lead to the Nano, I can access the Dashboard and the Internet, but cannot load bulletins, etc.
Any help is highly appreciated!
