What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared-key algorithm, as
described in the IEEE 802.11 standard.
What is a MACAddress?
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, be 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 PC 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 PC 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, due to FCC regulations, more power may be transmitted, using 802.11a, on
channels 52, 56, 60 and 64, than on the lower channels. Lastly, check the Advanced tab of the
Web-Based Utility and make sure that FULL is selected in the Transmission Rate field.
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 I cannot see my network.
WEP is probably enabled on the Access Point, but not on your wireless adapter (or vice versa).
Verify that the same WEP Keys and levels (64 or 128 ) are being used on all nodes on your
wireless network. Also we suggest you check for MAC filtering.
What is the maximum number of users the Access Point facilitates?
No more than 65, but this depends on the volume of data and may be less if many users create a
large amount of network traffic.
How many channels/frequencies are available with the Access Point?
Using 802.11b or 802.11g, there are eleven available channels, ranging from 1 to 11.
