 If I have a cable modem, can I still use my old 28.8 Kbps or 56 Kbps modem? 

 Yes! Although once you’ve experienced the speed of cable Internet access, you’ll 

never again want to wait for traditional dial-up services. 

 

 Do I need to change my Internet Service Provider (ISP)? 

 Currently, most Internet Service Providers do not provide cable Internet access. 

Contact your cable company for your specific information. 

 

 Do I need to subscribe to cable TV to get cable Internet access? 

 At a minimum you will need to subscribe to cable Internet service. Your Internet 

Service Provider may have a minimum level of video service you must subscribe to 
receive the broadband access service. Check with your local cable company for 
specific information. 

 

 I am not getting the data speeds I expected. 

 Contact your Internet Service Provider to verify the data bandwidth available to 

you. 

 

 I can receive files much more quickly than I can send them? 

 This modem has the capability to bond multiple downstream channels, which will 

increase the capacity to receive data. The upstream data path does not have the 
same capacity. Please verify the actual bandwidth available to you with your Internet 
Service Provider.
