Amazing Speed

The Killer 2.5 Gbps Ethernet Dongle automatically detects, classifies, and prioritizes network traffic and ensures the most important data is delivered fast and is prioritized over less important traffic.

  • Killer Prioritization Engine:The Killer 2.5 Gbps Ethernet Dongle uses the Killer Prioritization Engine to detect thousands of games, applications, and websites.  It then leverages Lag and Latency Reduction™ Technology to prioritize the most important packets for a fast, smooth online entertainment experience.
  • GameFast™ Technology:By automatically pausing processes that are not needed when gaming, Killer GameFast Technology frees up to 10% of your CPU cycles and 20% of your memory so that your game plays faster and smoother. Gamers who use GameFast will experience faster, more responsive game play with the additional system resources available to focus on the game.

Advanced Intelligence:

  • Killer Intelligence Engine:The Killer 2.5 Gbps Ethernet Dongle automatically analyzes the network and makes adjustments to improve the overall online experience.  For items that cannot be fixed automatically, the Killer Intelligence Engine makes recommendations to the user on how to best optimize their home network for ideal performance.
  • DoubleShot Pro: When combined with a Killer Wi-Fi product, the 2.5 Gbps Ethernet Dongle features DoubleShot Pro Technology, which enables the use of both Killer Wi-Fi and the 2.5 Gbps Ethernet Dongle at the same time.  DoubleShot Pro works automatically to ensure the highest priority traffic will always be put on the fastest and most reliable link. Users can also leverage the Killer Control Center 2.0 to determine which applications and websites go over wireless and which use Ethernet.

Powerful Control:

The Killer 2.5 Gbps Ethernet Dongle gives users more ways to control and enhance their online experience than ever before

  • Killer Control Center 2.0: Gives users an intuitive and rich interface to monitor which applications and websites are using bandwidth, and to optimize their PC’s networking performance. Users can adjust priorities and set bandwidth limits so that low priority traffic doesn’t interfere with multimedia applications or favorite websites
