*Note regarding OS and hardware minimum requirements for speeds over 100Mbps: Alternate hardware and operating systems that can use the INternet will work with this service; however, Comcast cannot demonstrate in testing that such devices and operating systems can attain the full provisioned rate of broadband speed.

Actual speeds may vary depending on the number, performance, and configuration of the following:

* Connected PC or connecting PCs
* Hardware (Processor (Single Core, Multi Core), RAM, Hard Drive (write speed capabilities))
* Router and connecting adapters (Gigabit Ethernet required for 100M)
* Software Applications
* Web Browser/Browser Plug ins (Flash/Java)
* Website/Server Limitations (Not all speed test sites are capable of testing 100M)
* Network Congestion

For optimal performance, consult your equipment manufacturer/software developer for required upgrades, configuration updates, or troubleshooting guides.
