There are several system parameters that can be altered on your PC in order to improve download speeds over the FiOS network.
The Speed Optimizer tool modifies your TCP/IP configuration to allow your computer to receive data at a faster rate.
What is TCP/IP?
TCP/IP Stands for Transmission Control Protocol/Internet Protocol and allows your computer to communicate with other networked computers over the Internet. The standard TCP/IP configuration is optimized for communications over small local networks.
Which parameters and settings does the Speed Optimizer modify?
- TCP 1323 Extensions - This parameter enables enhancements to the TCP/IP protocol that provide improved performance over
high speed connections.
- TCP Receive Window - This parameter specifies the number of bytes a sender (the source you are downloading from) may
transmit without receiving an acknowledgment. Modifying it determines the maximum size offered by the system.
- MTU (Maximum Transmission Units) - The MTU defines the largest single unit of data that can be transmitted over your
connection. The FiOS network requires an MTU of 1492 bytes.
