The Hawking HWL2A is an advanced version of the HWL1 and improves on many functions of the previous model. The most obviousis the addition of a Hi-Speed Wireless-G USB 2.0 Network Adapter as well as the ability to differentiate wireless networks with security enabled. The addition of a WiFi Adapter allows the user to detect an 802.11b or 802.11g wireless signal and effortlessly connect to that signal by attaching their Apple laptop or desktop directly to the HWL2A via USB 2.0. The hassle of powering up your laptop and connecting to wireless "hot-spots" is now significantly simplified by the HWL2A. Simply push the "LOCATE" button on the HWL2A, detect and connect. No more guessing and configuring for each specific wireless "hot-spot." The HWL2A is equipped with a new, re-designed, flip-open Hi-Gain Directional Antenna that serves two purposes: 1) When detecting wireless networks, the Hi-Gain Directional Antenna helps the user determine exactly where the source of the wireless network is coming from by showing stronger signals at different angles. 2) When connecting to a wireless network, the Hi-Gain Directional Antenna guarantees the strongest link possible and provides greater distance than current wireless network adapters on the market due to its advanced 5dBi antenna. The HWL2A also automatically recharges its batteries when connected to a laptop so you never have to worry about replacing the batteries.
