I'm helping a charter school with computers - said school has 3 ActionTecs.

The modems present a web-based interface - you should be able to configure yours by browsing to  They also come with Windows-based configuration software, but who wants to use THAT?

If you use the web-based interface, you probably want to start with the "non-windows setup". I suspect that IF you switch it to bridging mode, after that point it will be configurable only with the Windows software (no IP address, ya know).

If the modem is in bridging mode, then I'm pretty sure it won't do any authentication.

If the modem is in bridging mode, then it won't do dhcp serving. I don't know if IP address assignment is up to you, or if CU takes care of that.
