Perhaps, but cable providers tend to be finicky about which modems they support. Best to stick to a modem on the provider's approved list, which for Comcast is: http://mydeviceinfo.comcast.net/

I advocate the purchase of third-party hardware that is supported by your provider. No sense in giving Comcast one penny more than is absolutely necessary.
