Sorry, maybe I'm too lamer but Netinstall never works for me. Not just the 4.x versions but all.
Maybe LoL, but I found an interactive video on Youtube about howto use Netinstall and I was follow that step-by-step and it was worked there but doesn't works for me.
I dump the network traffic with Wireshark after router booted the netinstalls kernel and I see the UPD packets witch was sent by the router in every seconds:
When I press the "Install button" the Netinstall sends 6 packets:
In the previous topic I was wrote that I tried Netinstall version 3.26, 3.27, 3.28, 3.30, 4.0, 4.1 and are didn't works. All of them hungs for 10 seconds after I clicked "Install" button.
But ok, I waiting for the next release.
