I recently purchased a new PC with Windows XP. I did not do anything special to configure Windows XP networking to connect to Comcast HSI, but was wondering if there are instructions anywhere on how to configure Windows XP Networking properly for Comcast HSI? Im connected to the net, but download speeds are spiking.
There is nothing special to do. Simply make sure you have TCP/IP set to Obtain an IP address automatically, and you should be good, assuming your equipment is correctly installed and functioning. But that is not specific to Comcast.
There are many, many different ways to setup XP to talk to Comcast, depending on equipment and your personal needs. The simplest setup is one cable modem (provided by Comcast or your own) connected to your PC's ethernet port. Your XP setup has the drivers installed for the ethernet port and you have TCP/IP installed and configure to get a dynamic IP. That's all there is to it.
