Hi I have a similar problem. Did u find a fix.
Even you could have problems to use it correctly, do not give up and stay with netinstall. At worse, use serial console to force the device to boot in netinstall mode correctly. Maybe you set the netinstall options in wrong way or local firewall, antivirus, user rights or network settings on your pc prevents the successful recovery process.
i have exactly the same problem and now no more internet. Did you solve it?
