Wireless-G Range Expander
(or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if
one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can
recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low
power wideband noise and is rejected (ignored) by most narrowband receivers.
Would the information be intercepted while transmitting on air?
Wireless networks feature two-fold protection. On the hardware side, as with Direct Sequence Spread Spectrum
technology, it has the inherent security feature of scrambling. On the software side, the wireless series offers the
encryption function (WEP) to enhance security and access control. Users can set it up depending upon their
needs.
Can Linksys Wireless products support file and printer sharing?
Linksys Wireless products can work with Netware, Windows NT/2000, or other operating systems to support
printer or file sharing.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40-bit shared-key algorithm, as described
in the IEEE 802.11 standard.
What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any 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 Range Expander?
Press the Reset button on the back of the Range Expander 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
points in a network 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.
