The D-Link DWL-7100AP REV B is a versatile tri-mode, dual-band wireless access point designed for both home and small business environments. Operating on both the 2.4GHz and 5GHz frequency bands and supporting 802.11a/b/g standards, it offers a theoretical maximum data transfer rate of 108Mbps. This makes it suitable for a variety of applications, including web browsing, email, streaming media, and online gaming. This article provides information about the D-Link DWL-7100AP REV B and its Firmware 2.20 update.

Understanding the D-Link DWL-7100AP REV B

The DWL-7100AP REV B distinguishes itself with its tri-mode functionality, allowing it to operate as an access point, a wireless bridge, or a wireless client. This flexibility makes it adaptable to diverse network configurations. Its dual-band capability, supporting both 2.4GHz (802.11b/g) and 5GHz (802.11a) standards, provides options for reducing interference and optimizing network performance. The 2.4GHz band is widely used, while the 5GHz band generally experiences less congestion, leading to potentially faster and more reliable connections.

The 108Mbps data transfer rate, while not as high as more modern wireless standards, was a significant improvement at the time of its release and is still adequate for many basic networking needs.

Firmware Update 2.20: Enhancements and Considerations

Firmware is the embedded software that controls the functionality of the access point. Updating the firmware is crucial for improving performance, fixing bugs, and enhancing security. Firmware 2.20 for the D-Link DWL-7100AP REV B introduces several key enhancements. It’s essential to understand these changes to appreciate the update’s benefits.

Key Improvements in Firmware 2.20:

• Enabled Band 4 for DFS2 Class 2 Change: This refers to enabling specific channels within the 5GHz band that are governed by Dynamic Frequency Selection (DFS) rules. DFS is a mechanism designed to prevent interference with radar systems. Enabling Band 4 allows the D-Link DWL-7100AP REV B to utilize a broader range of 5GHz channels, potentially improving performance in areas where those channels are available. The "Class 2 change" likely signifies adherence to specific regulatory requirements related to DFS implementation.

• Added Support for Normal Channel List: The update includes support for a list of standard 5GHz channels: 36, 40, 44, 48, 149, 153, 157, 161, and 165. These are commonly used channels within the 5GHz band, ensuring compatibility with a wider range of wireless devices.

• Added Support for Dynamic Turbo Channel List: The firmware update brings support for dynamic turbo channels 40, 153, and 161. Turbo mode, a feature often found in older wireless devices, attempts to increase data throughput by using wider channel bandwidths. Dynamic turbo mode dynamically adjusts the channel width based on network conditions.

• Added Support for Static Turbo Channel List: Similar to dynamic turbo channels, the update adds support for static turbo channels 42, 152, and 160. Static turbo mode utilizes a fixed, wider channel bandwidth, potentially offering increased throughput but also being more susceptible to interference.

Important Considerations Before Updating:

D-Link explicitly warns against upgrading the firmware over a wireless connection. This is a critical precaution. A dropped or interrupted wireless connection during the firmware update process can corrupt the firmware and render the D-Link DWL-7100AP REV B unusable, requiring potentially complex recovery procedures or even replacement. Always use a hard-wired Ethernet connection for firmware updates.
