Processor Speed (CPU)
The faster the processor, the faster your computer runs. We recommend a minimum of 1.5 GHz for PCs, and at least 800 MHz for Mac.

Free up hard drive space Your web browser has a Temporary Internet Files cache, which contains a record of everything you’ve downloaded, such as images, web pages and cookies. This takes up space on your computer, and causes it to run slower. We recommend clearing your cache on a regular basis.
Run a Windows Defrag and Scandisk If you use Microsoft Windows, tune up your filesystem to ensure it’s running properly, with Defrag and Scandisk. Defrag defragments your disk, and organizes your filesystem to help Windows read files faster. Scandisk checks your hard drive to make sure it has no problems. We recommend running these two tools once a month to keep your computer running at peak speeds.
Your Modem
If your Internet connection seems slow, check to make sure you’re using a Comcast Approved modem. Ultra and Extreme 50 customers should use a DOCSIS 3.0 compatible modem. Then power cycle (reboot) your modem, which will also download any available updates.Find out how to power cycle your modem. If you use a digital voice modem to access the Internet and make phone calls, here’s how to power cycle your voice modem.
Your Wireless Network Equipment
The three major wireless standards are b, g and n, with n being the newest and fastest. We recommend using an 802.11n-capable router as it provides the best coverage and fastest wireless speeds.EasySolve - Free for XFINITY Internet Customers
