The provider is DSL Extreme. I'm using the DSL modem they sent me.
 From what I can tell it uses DHCP. Also, I'm using a hub.

The modem has lights for power, ready, ethernet, usb. I'm not using usb.
The power, ready, and ethernet lights are on steady. Occasionally the
ethernet light blinks.

The hub has steady lights for power, the uplink and one computer.
Occasionally the uplink light blinks.

I don't see lights that indicate half-duplex or full-duplex.

Thank you for responding.
