Hello,

I'm running a win2k sp4 pc and I've tried unsuccesfully to install a d-link 300t modem (and I don't have a router for the moment). My internet provider (in France) says I have to enter the following :

VPI : 8
VCI : 36
Encapsulation : RFC 1483 routed VCmux

(and I don't have to enter a login/password anymore).

So I've configured the modem in bridge mode, and set vci to 36, dhcp is enabled. The modem detects the dsl line (all lights are ok), even detects upload and download speed, says it is connected, but, of course, nothing works.

I've tried the 4 tests : F4 and F5 end to end and segment (and don't know what it is !), and all of them fail.

Can someone help me ? How can I be sure my modem uses rfc 1483 (I know it supports it) ?

Thank you,

Miss

Why in bridge mode? I would think you would need a username and password to authenticate.

Not with RFC1483 (as opposed to PPPoE/PPPoA) -- the authentication is being done by the ISP based on which physical line is in use.

RFC1483 bridged and RFC1483 routed are two different things. If your ISP said to use routed and you've set it to bridged, you're not going to get anywhere.

Ok, thank you. Is it possible to set that modem in "routed" ?

Broadband modems (DOCSIS, xDSL) always act as a bridge. Authentication isn't usually needed with DSL as it's a single, dedicated line (at least from the last multiplexer).

Ok, thank you. Is it possible to set that modem in "routed" ?I'm not sure. In that Type dropdown where you've set it to bridged, what are all the available options?

Well, there are other options, but only PPPoE, PPPoA and static. But none works.

But since you've learned me bridged and routed RFC 1483 is not the same, I've taken a closer look at it. In the manual, they say this modem supports Bridged ethernet over ATM (Bridged RFC 1483). And I need IP over ATM (routed RFC 1483). So it won't work.

Am I right ?

But the dealer told me I can send the modem back.

Now I have to look for one which works.

Thank you for your help.

(I suppose I should set this thread as "solved", but how ??)

Ask your ISP what they recommend.

As for marking the thread resolved, it's under "Thread Tools" near the top.
