The DWL-650+ is an enhanced 802.11b CardBus that is fully compatible with the IEEE 802.11b standard; making it interoperable with all existing 802.11b-compliant devices. Now you can transfer files or communicate up to 20 percent faster than with earlier 802.11b solutions; even when connected to a standard 802.11b network. When you're connected to other D-Link AirPlus products; the performance is even greater--up to 22 Mbps. The DWL-650+ also features 256-bit WEP encryption; giving you a higher level of security for your data and communications. The D-Link AirPlus DWL-650+ also includes a configuration utility to discover available wireless networks and create and save detailed connectivity profiles for those networks accessed most often. The DWL-650+ is a powerful 32-bit CardBus adapter that installs quickly and easily on laptop PCs; and; when used with other D-Link AirPlus products; automatically connects to the network. And all D-Link wireless adapters can be used in ad hoc mode to connect directly with other cards; or in infrastructure mode to connect with a wireless access point for access to the Internet in an office or home network.
