System Status

The System Status pages show currently associated clients, general

 

information about the access point, and details about wireless

 

configuration settings.

 

 

Changing Access Point The Access Point Properties page displays the properties of the selected access

Propertiespoint. You can change properties by entering values in the fields and clicking the radio buttons described below. When you are finished, click Save.

■Device Name—This name appears on the device manager window.

■Device Location—Optionally, you can enter the location of the access point.

■Wireless LAN Service Area—To enable clients to roam among multiple access points, the access points must have identical WLAN service areas. To maintain wireless association, the WLAN service area on the client and the access point with which it is associated must match exactly. If you are associated with the access point that you are configuring and you change the access point WLAN service area, make sure to change the client WLAN service area also.

Setting Network Properties

The Network Properties page lets you change the settings shown below.

■Network Setting—This setting lets you change the IP address of the access point.

To let the access point get an IP address automatically from a DHCP server, click Obtain an IP address automatically and click Save.

To specify an IP address, click Specify an IP address, enter the IP address parameters in the spaces provided, and click Save.

If you change the IP address, you cannot continue to configure the access point using the old IP address. If you want to continue configuring this access point, you must close your browser and start a new configuration session.

When you specify an IP address, the access point cannot act as a DHCP server. Make sure that clients are using IP addresses on the same network.

■Wireless DHCP Server—If your wired network has a DHCP server, it is recommended that you use it. However, the access point provides a DHCP server that can automatically assign addresses to clients in a simple, all-wireless network.

The access point’s default IP address is 169.254.xxx.1, where xxx is the last byte of the access point’s MAC address. When it is acting as a DHCP server, the access point can assign up to 253 IP addresses to currently associated wireless clients. The IP addresses range from 169.254.xxx.2 to 169.254.xxx.254.

If the access point detects that another DHCP server is available, all wireless clients get IP addresses from that DHCP server.

If your wired LAN DHCP server goes down, the access point assigns IP addresses after the lease periods on the previous IP addresses expire.

To let the access point act as a DHCP server when there is no other DHCP server available, click Enable and click Save.

11 Mbps specifications

3Com 11 Mbps was a pivotal product in the evolution of networking technology, paving the way for wireless communications as we know them today. Introduced in the late 1990s, this wireless LAN (Local Area Network) product utilized the IEEE 802.11 standard, which defined the protocols for wireless networking. Operating at a maximum data rate of 11 megabits per second, it offered users a revolutionary means of connecting devices without the constraints of physical cabling.

One of the main features of the 3Com 11 Mbps solution was its simplicity and ease of installation. Unlike traditional wired networks that involved intricate setups of cabling and switches, 3Com facilitated a swift deployment process. Users could set up a wireless network in minutes, allowing organizations to enhance their productivity without extensive infrastructure.

The technology behind 3Com 11 Mbps was based on Direct Sequence Spread Spectrum (DSSS) modulation. This approach spread the signal over a wider frequency range, which improved resistance to interference from other devices. The 2.4 GHz frequency band used by this network supported compatibility with various devices, making it a flexible option for businesses and homes alike.

In terms of security, 3Com incorporated Wired Equivalent Privacy (WEP), which aimed to provide a level of data confidentiality comparable to that found in wired networks. However, WEP was later found to have vulnerabilities, leading to the development of more secure protocols like WPA (Wi-Fi Protected Access) and WPA2 in subsequent technologies.

Another characteristic that distinguished the 3Com 11 Mbps system was its ability to support multiple devices simultaneously. With the emergence of wireless laptops, printers, and other peripherals, a single access point could service several users without significant performance degradation.

Ultimately, the 3Com 11 Mbps was a significant stepping stone in the development of wireless technology. It showcased the potential of wireless networking and set the standard for future innovations. Although much faster and more secure wireless technologies have since emerged, the legacy of 3Com 11 Mbps resides in the fundamental advancements it brought to the realm of connectivity, making it easier and more accessible for users around the globe.
