D-Link Air DWL 900AP Review

By
March 25th, 2004


Summary

The D-Link DWL-900AP is an IEEE 802.11b wireless access point with point-to-point bridging capability that provides an easy solution for connecting two locations through a wireless connection. The DWL-900AP utilizes the 2.4 GHz Direct Sequence Spread Spectrum (DSSS) at 11Mbps with either "point-to-point bridging" or "point-to-multipoint bridging." In addition, the DWL-900AP provides an option to be configured as a client AP instead of a bridge. The DWL-900AP can be managed remotely via the SNMP (Simple Network Management Protocol) Manager software. In addition, a USB port is provided for flexibility in configuring the device.In bridge mode, the DWL-900AP can connect directly to another DWL-900AP to extend the area of coverage for the wireless network. In a network with a DHCP server, the DWL-900AP will automatically obtain an IP address.
