Since few days ago this trick no longer work.

From the modem that i enabled the web access and telnet terminal, i wasnt able to key in "ethernet ", after typing in ethernet, could not press space, but can type space after "display", something was changed in the modem, even i didnt do so.

The Login screen seems different, it says password is default, please change, i dont remember got such thing. Then I saved the configuration file then reset the modem. I no longer able to access the telnet and web. Could not do this trick anymore to unlock, even i wrote a simple application constantly attempt to connect into 192.168.100.1, connect 10 times per second every second, just attempting to connect, not sending any data, but not successful at connecting at all, but still able to use the old thomson router to connect into internet.
