has anyone been able to change the password on this device with success?
I appeared to have the same issue at one point... I needed to restart firefox, then it accepted the new password, otherwise try "admin"

Have you tried a factory reset if all else fails?

Router is now in bridge mode.
For future reference, its pvc 0/38 rather than 0/35.

Thanks guys, brilliant find!
How do you change the pvc? do you need to edit the binary backup settings.conf or can you somehow change it with the gui?

Try http://192.168.1.254/dumpcfgdynamic.cmd . it should dump the config in text mode, then you'll see the PVC settings

Yes, I can see <DestinationAddress>PVC: 0/38</DestinationAddress> in this xml but how can you change it? (if I used the .conf linked by Darsh to put the router in bridge mode)

Re: Unlocking the potential of Sagemcom 2704N

Regarding - http://192.168.1.254/dumpcfgdynamic.cmd
You can copy & paste that config into a file E.G. "my-april-config.conf" - if you have changed the bridge mode already - that change is reflected in the most recent config that is displayed.
Then you can upload the file to http://192.168.1.254/updatesettings.html
( I hope that made sense! )

EDIT:
You could try http://192.168.1.254/modconn.cmd?action=view
but I dont know if it will allow you to edit it using the stock firmware

Re: Unlocking the potential of Sagemcom 2704N

Hello, I made a couple of changes to the the firmware again is anyone wants it:
https://drive.google.com/file/d/0B4-Ln6UubyEeb2l0RUFUekFFOFU/
Changed Netcat for a static Telnet  (smaller memory footprint)
Changed the PSI, so bigger configs are saved between reboots

Hi Darsh & Matty123123
Just to let you know, I know I'm not the only one that is appreciating your efforts and following this thread with interest - even if I haven't got to grips with (or understood Shocked ) some of it.
Keep up the good work please. Smiley

Re: Unlocking the potential of Sagemcom 2704N

Hello, I thought I'll write how I opened up the router, attached is a sort-of "DIY guide" if someone would like to do it manualy.
I think I've exhausted all my knowledge now...
