106CHAPTER 6: TROUBLESHOOTING

■If you have a wired and a wireless NIC in the same computer, ensure that the wired NIC is disabled.

■Check the status of the Router Wireless LED, it should be lit if wireless is enabled and will flash when there is wireless activity. If not lit go to “Wireless Settings” and enable wireless networking.

■Ensure that the TCP/IP settings for all devices are correct.

■Ensure that the Wireless Clients are using the same SSID or Service Area Name as the Router. The SSID is case-sensitive

■Ensure that the encryption method and level that you use on your clients are the same as those configured on the Router. The Router can simultaneously support WPA and WEP encryption, but can only support one configuration of each.

■Ensure that you have the Wireless computer enabled in the list of allowed MAC addresses if you are using Wireless Connection control on the Router.

■If you are having difficulty connecting or are operating at a low speed try changing the antenna positions on the rear of the Router. For more effective coverage you can try reorientating your antennae. Place one antenna vertically and one horizontally to improve coverage.

Additionally consider moving the wireless computer closer to the Router to confirm that the building structure or fittings are not adversely affecting the connectivity. If this resolves the problem consider relocating the Wireless computer or the Router, or trying a different channel on the Router.

■Sources of interference: The 2.4Ghz ISM band is used for 802.11b and 802.11g. This is generally a licence free band for low power applications, and you may have other devices at your location that operate in this frequency band. You should take care to ensure that there are no devices like microwave ovens for example close to the Router or wireless computers as this could affect receiver sensitivity and reduce the performance of your network. If you are unsure try relocating both the wireless computers and the Router to establish whether this problem exists.

■Most wireless computer Adapters will scan the channels for the wireless Router. If a wireless computer has not located the Router then try initiating a search manually if the client software supports this feature or manually set the channel on your wireless computer to correspond to the Router channel number. Please refer to your Wireless computer adapter documentation and vendor to do this.

WL-537, WL-537S specifications

The 3Com WL-537S and WL-537 are advanced wireless access points designed to enhance networking capabilities in both enterprise and residential settings. These models are part of 3Com's effort to provide reliable connectivity, improved performance, and robust security.

The WL-537S is particularly notable for its versatility and extended range. It supports both 2.4 GHz and 5 GHz frequencies, allowing users to choose between a wider range or higher speed depending on their needs. With 802.11n technology, it offers significant improvements in data rates and reach compared to earlier standards. This dual-band functionality enables users to run multiple applications simultaneously without sacrificing performance. The access point can handle higher traffic volumes efficiently, making it ideal for environments with many users.

One of the standout features of the WL-537S is its integrated Power over Ethernet (PoE) capability, which simplifies installation by allowing the device to receive power and data over a single Ethernet cable. This is particularly useful in locations where power outlets are limited or hard to reach. Additionally, the access point’s lightweight, compact design allows for easy mounting on ceilings or walls, providing versatility in deployment.

Both models offer advanced security mechanisms, essential for protecting sensitive information in a network. They come equipped with multiple encryption protocols, including WPA2 and WPA3, ensuring that data transmission remains secure. Moreover, with features like Remote Authentication Dial-In User Service (RADIUS) support and VLAN tagging, organizations can implement fine-grained control over user access and data traffic.

Additionally, the WL-537 and WL-537S support several network management features, including a web-based interface for easy configuration and monitoring. This feature is particularly useful for IT administrators who need to manage settings remotely or troubleshoot issues.

Dynamic load balancing is another key characteristic of these access points. By distributing the network load evenly among connected devices, the WL-537S and WL-537 ensure that no single device gets overwhelmed, thus maintaining optimal performance across the network.

In conclusion, the 3Com WL-537S and WL-537 access points combine robust technology, security features, and flexibility to meet the demands of modern networking. With their dual-band capabilities, PoE integration, and management features, they provide an ideal solution for users looking to enhance their wireless network experience.
