You can improve your computer's performance by running one of the Registry Files below. These files quickly tune your computer's TCP/IP and MTU settings.

The Registry Files below provide a way to modify your computer's TCP/IP configuration to allow your computer to receive data at a faster rate and therefore, maximize your Internet throughput performance with FiOS.

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 do the below Registry Files modify?

      1. TCP 1323 Extensions - This parameter enables enhancements to the TCP/IP protocol that provides improved performance over high speed connections.

      2. 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.

      3. 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.

To optimize your computer, select your correct Operating System, FiOS Internet Speed & follow the corresponding instructions



Step 1 Click the Registry File below. (TCP/IP and MTU settings will be applied to your computer.)

       All_Speeds_W2K_XP.reg

Step 2 Reboot your computer. (This is necessary in order for new parameter settings to take place.)
