Finally got to tinker with mine tonight got to gui 3.9 and fw 1.0.3.
I couldn't quite get connected though, sync was roughly the same as may hg612. Is there no way to set up the connection in the gui?
I tried the below config files as mentioned but think I may be going wrong. I need a username and password for my ISP but there is no vlan id etc to set up.
vpi/vci is 0,38 where does that go, also vcmux.
/etc/config/network
edit: The setup wizard seems to hang, but I can see it worked fine for you in the earlier screenshots.
