Cisco WAP2000 Wireless-G Access Point with Power Over Ethernet Administration Guide
What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter, that
allows the network to identify it at the hardware level. For all practical purposes,
this number is usually permanent. Unlike IP addresses, which can change every
time a computer logs on to the network, the MAC address of a device stays the
same, making it a valuable identifier for the network.
How do I avoid interference?
Using multiple access points on the same channel and in close proximity to one
another will generate interference. When employing multiple access points, make
sure to operate each one on a different channel (frequency).
How do I reset the access point?
Press the Reset button on the back of the access point for about ten seconds. This
will reset the unit to its default settings.
How do I resolve issues with signal loss?
There is no way to know the exact range of your wireless network without testing.
Every obstacle placed between an access point and wireless computer will
create signal loss. Leaded glass, metal, concrete floors, water, and walls will inhibit
the signal and reduce range. Start with your access point and your wireless
computer in the same room and move it away in small increments to determine the
maximum range in your environment.
You may also try using different channels, as this may eliminate interference
affecting only one channel. Also, open the access point's web-based utility, click
Wireless > Advanced, and make sure the output power is set to 100%.
Does the access point function as a firewall?
No. The access point is only a bridge from wired Ethernet to wireless clients.
I have excellent signal strength, but cannot see my network.
Wireless security, such as WEP or WPA, is probably enabled on the access point,
but not on your wireless adapter (or vice versa). Verify that the same wireless
security settings are being used on all devices in your wireless network.
What is the maximum number of users the access point can handle?
No more than 45, but this depends on the volume of data and may be fewer if
many users create a large amount of network traffic.
