Help with Netgear DGND3700 v1

Greetings everyone,

I am a noby and i need some help for the configuration of ADSL in my router.

I did install the latest version of the firmware (factory) OpenWRT for my router, after that i upgrade (sysupgrade) and everything works.

I try to follow all the guides, videos and forums i did find to my router but without fortune.

The ADSL wont function by any means, that's why i am here today asking for your help.

Best Regards,
SysV.

Modems usually don't work, only a few exceptions do work.
