cFosSpeed

cFosSpeed is high speed network driver, an advanced Traffic Shaper, which will make you forget about lags and high ping while downloading anything and playing online games, streaming videos or simply surfing Internet.

cFosSpeed acclaimed and used by ASUS, GIGABYTE, ASRock and MSI as official Internet Accelerator for their gaming products.

cFosSpeed attaches itself to existing Internet connection and prioritizes its connections with Traffic Shaping technology.

Traffic Shaping sorting packets by importance and ensuring that connections with higher priority will always receive more bandwidth first, which results in better response time, less lags and lower ping time.

It allows users to play games, watch videos or listen music online, use VoIP or surf the Internet even when Internet connection heavily loaded by, for example, downloading of torrents.

cFosSpeed can be used for all access types: DSL, Cable, Mobile Broadband (2G/3G), Wi-Fi, etc. 

Use your real bandwidth: high speed, low ping!
