To uninstall cFosSpeed, users need to look for a folder named “LanManager.” This will typically be located in Program Files (x86) as a subdirectory of the OEM application. Users have reported that cFosSpeed decreases network speeds and causes websites like YouTube and Facebook to lag. However, most mid-to-high-end routers provide the same functionality but actually work. It’s an unnecessary program that works as a traffic shaper.

None of the settings you set will activate until you click CALIBRATE LINE.

After all that is done click CALIBRATE LINE under traffic shaping. if you download things often you want to set the traffic shaping priority to BANDWIDTH or if you're gaming you can set it to favor PING, right click cfoss in system tray, hover over traffic shaping, then click FAVOR BANDWIDTH or when gaming FAVOR PING. I like setting my games to the 'higher' priority as well as my browser, and everything else to 'lowest'. In that window you can set the internet priority of your programs. When you right click cfoss program in the system tray and go to CURRENT CONNECTIONS, you will see the list of all the programs using your internet. Lets say you have some background programs open like Discord or Spotify. Kind of like when you go to task manager, right click program, go to details, and set the program at high CPU priority. It allows you to set your internet priority to favor PING or BANDWIDTH, and on top of that it allows you to set the internet priority for each program that runs on your computer. Its a traffic shaping tool that is heavily geared towards computer savvy tweakers. Hey, I personally use and love this program and would like to inform you on what the program specifically does to your internet.
