Appendix A: Troubleshooting

Check the following items before you contact local Technical Support.

1.If wireless clients cannot access the network, check the following:

•Be sure the access point and the wireless clients are configured with the same Service Set ID (SSID).

•If authentication or encryption are enabled, ensure that the wireless clients are properly configured with the appropriate authentication or encryption keys.

•If authentication is being performed through a RADIUS server, ensure that the clients are properly configured on the RADIUS server.

•If authentication is being performed through IEEE 802.1X, be sure the wireless users have installed and properly configured 802.1X client software.

•If MAC address filtering is enabled, be sure the client’s address is included in the local filtering database or on the RADIUS server database.

•If the wireless clients are roaming between access points, make sure that all the access points and wireless devices in the Extended Service Set (ESS) are configured to the same SSID, and authentication method.

2.If the access point cannot be configured using the Telnet, a web browser, or SNMP software:

•Be sure to have configured the access point with a valid IP address, subnet mask and default gateway.

•If VLANs are enabled on the access point, the management station should be configured to send tagged frames with a VLAN ID that matches the access point’s management VLAN (default VLAN 1, page 6-17). However, to manage the access point from a wireless client, the AP Management Filter should be disabled (page 6-17).

•Check that you have a valid network connection to the access point and that the Ethernet port or the wireless interface that you are using has not been disabled.

•If you are connecting to the access point through the wired Ethernet interface, check the network cabling between the management station and the access point. If you are connecting to access point from a wireless client, ensure that you have a valid connection to the access point.

•If you cannot connect using Telnet, you may have exceeded the maximum number of concurrent Telnet sessions permitted (i.e, four sessions). Try connecting again at a later time.

SMC2552W-G2-17, SMC2552W-G2 specifications

The SMC Networks SMC2552W-G2 and SMC2552W-G2-17 are advanced wireless access points designed for a range of networking environments, offering robust features suited to both home and business applications. These devices are known for their reliable performance, making them a popular choice for those seeking to enhance network connectivity and coverage.

One of the primary features of the SMC2552W-G2 is its dual-band capability, operating on both the 2.4 GHz and 5 GHz frequency bands. This versatility allows users to take advantage of the high capacity of the 5 GHz band, which is less congested and ideal for activities that require substantial bandwidth, such as streaming and online gaming. The 2.4 GHz band, on the other hand, provides better penetration through walls and is more suitable for basic browsing and mobile device connectivity.

Another significant characteristic is the device's support for the 802.11n Wi-Fi standard, which enables data rates of up to 300 Mbps. This standard ensures a fast and stable wireless connection, facilitating a seamless online experience for multiple devices simultaneously. The integration of MIMO (Multiple Input Multiple Output) technology further enhances the performance, allowing for multiple data streams to be transmitted and received, significantly increasing throughput and range.

The SMC2552W-G2 series also boasts advanced security features, including WPA/WPA2 encryption and support for 802.1X authentication. These security protocols provide robust protection against unauthorized access and ensure that data transmitted over the network remains secure.

In terms of management, these access points offer both web-based and SNMP (Simple Network Management Protocol) interfaces, enabling users to easily configure and monitor the network settings. This user-friendly interface simplifies the process of overseeing network performance and troubleshooting issues when they arise.

The SMC2552W-G2 and SMC2552W-G2-17 are designed for easy installation, whether as stand-alone units or as part of a larger network. Their compact design allows for flexible mounting options, making them suitable for various environments.

In summary, the SMC Networks SMC2552W-G2 and SMC2552W-G2-17 provide an excellent combination of speed, security, and ease of management, making them ideal solutions for enhancing wireless connectivity in both home and office settings. Their dual-band functionality, compliance with the latest Wi-Fi standards, and comprehensive security measures ensure a reliable and efficient networking experience.
