Also a reset of the Speedstream 5851 defaults back to Bridged 1483, but with a VP/VC of 0/38. Change it to 0/35.

For the Speedstream 5851, another modem/router combo (the one listed on this page is the 5861):

the username is “superuser” and the password is “admin”.

All the other info on this page seems to apply.

I sympathize with the folks at your ISP. Part of the reason this article exists is that the 5681 was never distributed by my employer, and therefore we do not officially support it. There are really only a couple of factors that play in with your DSL modem being compatible with your ISP. Beyond that, whether a modem is “supported” by an ISP has more to do with trying to limit the number of interfaces the technical support folks are expected to be conversant with.

* Is your modem able to synchronize with the DSLAM? It’s got to be able to use the same protocol (e.g. G.dmt), and use the same trunk VPI/VCI pair. I don’t know what you guys use up there, but in California older connections use VPI 8 by VCI 35, and newer connections use 0 by 35. The modem also has to use the same encapsulation (e.g. LLC/SNAP).
* Is your connection using PPPoE to authenticate and establish its network info, or just authenticating by circuit ID and issuing network info by DHCP? This article is intended to help folks switch from PPPoE to just bridging the connection through and letting the end-user’s computer deal with it, which is how it needs to be set up for Sonic.net. If your ISP uses PPPoE (many do), then following the above instructions will really shoot you in the foot.

Thanks. I talked to the ISP and they said this model wasn’t on their “supported” list. Should that have any influence on connecting? I need to establish a connection in order to access the modem/router’s config program.

If your Macintosh is getting the same IP address as it thinks its router is on, that’s a pretty sure sign of trouble. Normally you’d expect the gateway to be either the second or second-to-last IP in the block (e.g. 192.168.0.1 or 192.168.254.254), and the IP assigned to your computer would be some other address as specified by your router’s DHCP server. I would expect that you wouldn’t even be able to access the 5861’s interface with that setup.
