and scroll down a few messages and you'll find a post from BrianT. That explains how to get yor backup file decrypted. Then search that file for your sip info. You can change the admin password but sagemcom modem is so crippled with firmware it's not worth keeping. So just extract your sip info and get another modem. I got the dlink talkbox 2800 and it all worked. The only problem with this midem it doesn't have a print server so you have to shsre the printer via a networked computer. The other modem i was looking at was the fritzbox 7490. Both modems are listed on nbn website as being totally compatible with the nbn.
