Appendix B: Setting Up The Tcp/Ip And Ipx Protocols; Setting Up Tcp/Ip In Windows - Linksys WAP55AG User Manual

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, 128 or 152) are
being used on all nodes on your wireless network.
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 802.11a, there are eight available frequencies, ranging from 5.15GHz to
5.32GHz. Using 802.11b, there are eleven available channels, ranging from 1
to 11.
What is Turbo mode?
Turbo mode allows high-speed connections, but severely limits range. Turbo
mode must be enabled on both the Access Point and the wireless PCs to func-
tion. Turbo mode is not compatible with Windows XP and may only function
with Linksys 5GHz wireless adapters.
What is the difference in range between 802.11a and 802.11b products?
Overall, range will be a little
less in a typical environment,
while higher speeds may be
achieved with 802.11a, through-
put degrades more quickly. (See
Figure A-1.)

Appendix B: Setting Up the TCP/IP and
IPX Protocols

Setting Up TCP/IP in Windows

Before a computer can communicate with the Access Point, it must be config-
ured with the TCP/IP protocol. If you know how to set up TCP/IP on your com-
puters, do so now. Otherwise, use the guidelines below to help get TCP/IP
installed on all of the computers that need to communicate with the Access
Point. If you are unable to successfully install TCP/IP on one or more comput-
ers after following the directions, contact the manufacturer of your computers'
network operating system for further assistance. Check with your network
administrator for your TCP/IP settings.
The directions below provide general guidelines for coming up with IP address-
es and subnet masks. Check with your network administrator to see if you need
to use specific IP addresses or DHCP settings.
First, each computer on the network will require an IP address, which is a series
of numbers, separated by periods, identifying the PC on the network. To make
things simple, you should use the following numbering scheme:
192.168.1.X
In this example, X is a unique, arbitrarily assigned number from 1 to 254. Each
computer must have its own unique X number. Note: Never use 0, 250 or 255
for X. These numbers are reserved by TCP/IP for other uses.
For example, if you have three computers, you could number them as follows:
192.168.1.17
192.168.1.44
192.168.1.126
In this case, 17, 44, and 126 are arbitrary numbers between 1 and 254.
Each computer will also require a subnet mask, which is a numerical "filter"
that tells a computer what kinds of TCP/IP data packets to accept. If you're not
sure which mask to use, the following mask is recommended:
255.255.255.0
