I purchased a DVG-1402S from Monarch Technologies (online webshop) and bought voice service through BroadVoice. It seems that the DVG-1402S/L (completely different machine) REQUIRES Lingo as the voip provider. After several phone calls to Dlink's support, they assured me that the DVG-1402S would work with BroadVoice... maybe.
BroadVoice sent me the configuration information that I needed to access their service.
DLink's router has these configuration options hidden under the "Advanced" tab, requiring a login/pass.
Stuff I tried that didn't work:
L/P: Admin Admin
my dsl pppoe info
DLink assured me that they didn't have this password to provide. They claimed that their parent corp, Primus, has this info. After three calls to Primus hq, still no dice. They claim "we'll get back to you."
Dlink also referred me to Lingo, claiming that THEY had the password. Five or six calls, managed to get a Lev 3 tech on the horn, still no dice. All the Lingo techs really did was try to sell me Lingo service when I tell them that I'd bought service through BroadVoice. End result? Since I was a BroadVoice customer, Lingo was really unhelpful.
A Dlink tech told me that the passwords for each box are unique, burned in by hand by folks at Primus HQ. Nobody at Primus HQ seems to know a thing about this.
I'm about to pack up this piece of junk and get another adapter. I should have known better. Dlink products rarely work properly in my experience. Go with Siemens, go with 3Com, not with Dlink.
Nobody at three whole corporations involved with the DVG-1402S seem to know anything helpful.
Let me sum up by saying: "STAY AWAY FROM DLINK PRODUCTS!" (Probably Lingo, too, while you're at it.)
I hope this provides a little more info, sorry I couldn't post anything more.
