How fast will a cable modem download and upload data?
Network speeds can reach up to 250Mb/s, but speeds will also depend on the service level to which you subscribe. The asymmetric cable modem scheme is the most common type of cable network setup, and will allow for a faster data transmission rate (higher bandwidth) on the downstream data path than the upstream data path. This network setup works well since most cable modem users download more information than they send. For example, downloading web pages and multimedia files and watching streaming services requires much more bandwidth than sending web page requests or e-mail.
