|cr, What cable system are you using that modem on? The specs state the model is a docsis 2.0 model. Newer modems are docsis 3.0. If your provider is using docsis 3.0 I recommend you exchange it. |
If you purchased the modem as new, I suggest you return it anyway and get one that is complete. The lack of the CD may indicate the unit is used and returned. If that is the case it may be defective.
One last point, did you check with your cable provider to verify that model is compatible with their system?
