If you want to increase speed of your Internet access, but not likely to purchase a new modem or upgrade service plan with your Internet provider, you may land on trying absolutely free software-based solution.
The SG TCP Optimizer is so-called "Internet Accelerator" which may help to dramatically boost your Internet speed. It optimizes Internet-related settings on your end of the connection (your PC), allowing for faster throughput.
The program works with any Internet connection, from dialup to leased lines, regardless of your Internet Service Provider (ISP). It is a completely free utility, that supports all current Windows versions, and it can improve Internet speed as much as 200% in some cases, at no additional cost to you. It is completely legal, and often recommended by ISPs as a tool to troubleshoot and optimize internet connections.
The SG TCP Optimizer works best for optimizing broadband Internet connections, however it will work for dial-up and LANs to a degree. Note that it is a program that optimizes your end of the connection, and you will still be dependent on the feed that your ISP provides.
There is no installation required, just download and run.
The program can aid both the novice and the advanced user in tweaking related TCP/IP parameters in the Windows Registry, making it easy to tune your system to the type of Internet connection used. The tool uses advanced algorithms, and the bandwidth*delay product to find the best TCP Window for your specific connection speed. It provides for easy tuning of all related TCP/IP parameters, such as MTU, RWIN, and even advanced ones like QoS and ToS/Diffserv prioritization.
