I bought a Zyxel NBG6616, as a first thing I updated the firmware (with online automatic procedure in the web UI).
I waited for 300 seconds as requested: the router did not seems to work (no answer to the ping, no wireless, no access to the web UI).
I waited for other 40 minutes, but the situation was still the same: then I plug-in/plug-out the router, but still nothing changes.
The I resetted the router (with the reset button): now the router answers to the ping, but refuses connection to the port 80 (for the web UI) or 23 (for telnet). It seems to accept connection to its tftp server, but when I try to upload something (even if I don't know what I have to upload), the transfer ends in a timeout.
So I guess my ZyXEL is bricked, what can I do?
