CHAPTER 4: ACCESS POINT CONFIGURATION
Profile
Figure 33 Profile Screen
Some 3Com Wireless Network Adapters allow you to import Wireless
configurations via a ‘profile’. The Access Point can generate a profile so
that you do not need to configure your Wireless PCs manually.
The profile contains three items as follows:
■
Service Area Name/SSID of the Access Point
This is configured on the Configuration tab under the Wireless
Settings option.
■
Encryption settings from the Access Point
This is configured on the Encryption tab under the Wireless Settings
option.
■
Profile Name
This is used to identify the profile once it has been imported into the
Wireless Network Adapter configuration software.
Wireless Settings
47
Saving a Profile
To set up a profile (once the Service Area Name/SSID and Encryption
settings have been configured in the Access Point):
1 Enter a Profile Name (up to 25 alphanumeric characters) and then click
Save Profile.
2 Your browser will then prompt you to enter a file name and folder
location in which to save the profile. Once the profile has been saved it
can be copied on to another PC and imported into the 3Com Wireless
Network Adapter.
For instructions on how to import a profile, refer to the User Guide that
accompanies your 3Com Wireless Network Adapter(s).
If, once the profile is imported, the Wireless Network Adapter cannot
connect to the Access Point, check that:
■
the adapter is within range of the Access Point
if Connection Control has been enabled in the Access Point, the MAC
address of the Wireless Network Adapter must be included in the list of
authorised Wireless PCs.
Importing a Profile
You can import a profile that has already been saved.
1 Click Browse and navigate to the folder where you have saved the profile
on your admin computer.
2 Select the Profile you want to import and click Load Profile.
Only the Service Area Name and WEP settings will be imported from the
profile.

Backup Configuration
Click BACKUP to save the current Access Point configuration. You will be
prompted to download and save a file to disk.
Restore Configuration Data
If you want to reinstate the configuration settings previously saved to a
file, press Browse to locate the backup file on your computer, and then
click RESTORE to copy the data into the Access Point's memory.
The password will remain unchanged.
Reset to Factory Default
If you want to reset the settings on your Access Point to those that were
loaded at the factory, click RESET. You will lose all your configuration
changes. The Access Point reverts to a DHCP client and will therefore
restart requiring a new IP address. To communicate with the Access Point
you may need to rerun the DISCOVERY software to find out the IP
address of the Access Point. See Appendix A for more information. You
may need to reconfigure and restart your computer to re-establish
communication with the Access Point.
Upgrade

support web site to a folder on your computer. Once you have done this,
select Browse to tell your web browser where this file is on your
computer, and then click Apply. The file will be copied to the Access
Point, and once this has completed, the Access Point will restart.
Although the upgrade process has been designed to preserve your
configuration settings, it is recommended that you make a backup of the
configuration beforehand, in case the upgrade process fails for any
reason (for example, the connection between the computer and the
Access Point is lost while the new software is being copied to the Access
Point).
The upgrade procedure can take up to two minutes, and is complete
when the Alert LED has stopped flashing and is permanently off. Make
sure that you do not interrupt power to the Access Point during the
upgrade procedure; if you do, the software may be corrupted and the
Access Point may not start up properly afterwards. If the Alert LED comes
on continuously after a failed upgrade, refer to Chapter 5,
“Troubleshooting”.

TROUBLESHOOTING
■
Check that the Access Point is connected to your switch or hub and
that all the equipment is powered on. Check that the LAN port link
status LED on the Access Point are illuminated, and that any
corresponding LEDs are also illuminated.
■
Ensure that the computers have completed their start-up procedure
and are ready for use. Some network interfaces may not be correctly
initialised until the start-up procedure has completed.
■
If the link status LED does not illuminate for the LAN port, check that
you do not have a faulty cable. Try a different cable. Check also that
the Uplink/Normal switch is in the correct position.
If you have connected your Access Point, admin computer and switch
together but cannot browse to the Access Point configuration screens,
check the following:
■
Confirm that the physical connection between your computer and the
Access Point is OK, and that the link status LEDs on the Access Point
and NIC are illuminated and indicating the same speed (10Mbps or
100Mbps). Some NICs do not have status LEDs, in which case a
diagnostic program may be available that can give you this
information.
■
When entering the address of the Access Point into your web browser,
ensure that you use the full URL including the http:// prefix (e.g.
http://192.168.1.1).
■
If you cannot browse to the Access Point, re-run the DISCOVERY
software described in Appendix A to discover the Access Point and the
IP address it has been allocated from the DHCP server. If there is no
DHCP server on your network, the DISCOVERY software changes the
IP address of the Access Point so that it is in the same subnet as your
admin computer.
54
CHAPTER 5: TROUBLESHOOTING
Forgotten Password
and Reset to
Factory Defaults
If you can browse to the Access Point configuration screen but cannot log
on because you do not know or have forgotten the password, follow the
steps below to reset the Access Point to it’s factory default configuration.
CAUTION: All your configuration changes will be lost, and you will need
to run the configuration wizard again before you can re-establish your
wireless network. All other computer users will lose their network
connections whilst this process is taking place, so choose a time when
this would be convenient.
1 Remove power from the Access Point.
2 Hold down the Reset button on the rear of the unit and re-apply power
to the Access Point. The Alert LED will flash as the Access Point starts up,
and after approximately 30 seconds will start to flash more slowly
(typically 2 seconds on, 2 seconds off). Once the Alert LED has started to
flash slowly. Keep Reset button held down and remove power from the
Access Point.
3 Release the Reset button.
4 Re-apply power to the Access Point, and when the start-up sequence has
completed, browse to the IP address of the Access Point and run the
configuration wizard. You may need to restart your computer before you
attempt this.
5 When the configuration wizard has completed, you may reconnect your
network as it was before.
Wireless
Networking
■
Ensure that you have a Wi-fi certified 802.11b wireless adapter for
each wireless computer, and that it is correctly installed and
configured. Verify that each Wireless computer has either Windows
95 or higher or MAC OS 8.5 or higher.
■
Verify that your wireless computers are configured to work in
Infrastructure mode and not Ad Hoc mode. The Access Point is
designed to operate in Infrastructure mode. Ad Hoc mode is not
supported by the Access Point.
■
Check the status of the Access Point Wireless LED, it should be lit if
wireless is enabled and will flash when there is wireless activity. If not
lit go to “Wireless Settings” on page 37 and enable wireless
networking.
■
Ensure that the TCP/IP settings for all devices are correct.
Wireless Networking
55
■
Ensure that the Wireless Clients are using the same SSID or Service
Area Name as the Access Point. The SSID is case-sensitive
■
Ensure that you are using the same level of security on all of your
wireless computers (None, 40/64 or 128 bit) and that all devices are
using the same keys, and the same order of keys where appropriate.
■
Ensure that you have the Wireless computer enabled in the list of
allowed MAC addresses if you are using Wireless Connection control
on the Access Point.
■
If you are having difficulty connecting or are operating at a low speed
try changing the antenna positions on the rear of the Access Point. For
more effective coverage you can try reorientating your antennae.
Place one antenna vertically and one horizontally to improve coverage.
Additionally consider moving the wireless computer closer to the
Access Point to confirm that the building structure or fittings are not
adversely affecting the connectivity. If this resolves the problem
consider relocating the Wireless computer or select Clear Channel
Select on the Access Point.
■
Sources of interference: The 2.4Ghz ISM band is used for 802.11b.
This is generally a licence free band for low power applications, and
you may have other devices at your location that operate in this
frequency band. You should take care to ensure that there are no
devices like microwave ovens for example close to the Access Point or
wireless computers as this could affect receiver sensitivity and reduce
the performance of your network. If you are unsure try relocating both
the wireless computers and the Access Point to establish whether this
problem exists.
■
Most wireless computer Adapters will scan the channels for the
wireless Access Point. If a wireless computer has not located the
Access Point then try initiating a search manually if the client software
supports this feature or manually set the channel on your wireless
computer to correspond to the Access Point channel number. Please
refer to your Wireless computer adapter documentation and vendor
to do this.
■
Speed of connection: The 802.11b standard will automatically choose
the best speed depending on the quality of your connection. As the
signal quality weakens then the speed falls back to a lower speed. The
speeds are 11Mbps, 5.5Mbps, 2Mbps and 1Mbps. In general the
closer you are to the Access Point the better the speed. If you are not
achieving the speed you had anticipated then try moving the antenna
on the Access Point or moving the Wireless computer closer to the
56
CHAPTER 5: TROUBLESHOOTING
Access Point. In an ideal network the Access Point should be located
in the centre of the network with Wireless computers distributed
around it. Applications are generally available with the computer
wireless card to carry out a site survey. Use this application to find the
optimal siting for your wireless computer. Consult your Wireless Card
documentation and vendor for more details.
Alert LED
The Alert LED will flash when the Access Point unit is first powered up
while the system software checks the hardware for proper operation.
Once the Access Point has started normal operation, the Alert LED will go
out.
■
Recovering from
Corrupted Software
If the Alert LED does not go out following start up, but illuminates
continuously, this indicates that the software has detected a possible
fault with the hardware. Remove power from the Access Point, wait
10 seconds and then re-apply power. If the Alert LED comes on
continuously again, then a fault has been detected. Locate the copy of
the Access Point software on the accompanying CD-ROM or 3Com
web site (http://www.3com.com) and upload it to the Access Point to
see if this clears the fault (refer to “Recovering from Corrupted
Software” below). If this does not fix the problem, contact your
supplier for further advice.
If the Alert LED remains permanently on following power-up, it is possible
that the system software has become corrupted. In this condition, the
Access Point will enter a “recovery” state; DHCP is disabled, and the LAN
IP address is set to 192.168.1.1. Follow the instructions below to upload
a new copy of the system software to a Access Point unit in this state.
Ensure that one of your computers has a copy of the new software image
file stored on its hard disk or available on CD-ROM.
The latest software is available on 3Com’s Web site at:
www.3com.com.

IP ADDRESSING
The Internet
Protocol Suite
The Internet protocol suite consists of a well-defined set of
communications protocols and several standard application protocols.
Transmission Control Protocol/Internet Protocol (TCP/IP) is probably the
most widely known and is a combination of two of the protocols (IP and
TCP) working together. TCP/IP is an internationally adopted and
supported networking standard that provides connectivity between
equipment from many vendors over a wide variety of networking
technologies.
Managing the
Access Point over
the Network
To manage a device over the network, the Access Point must be correctly
configured with the following IP information:
IP Addresses and
Subnet Masks
■
An IP address
■
A Subnet Mask
Each device on your network must have a unique IP address to operate
correctly. An IP address identifies the address of the device to which data
is being sent and the address of the destination network. IP addresses
have the format n.n.n.x where n is a decimal number between 0 and 255
and x is a number between 1 and 254 inclusive.
However, an IP Address alone is not enough to make your device operate.
In addition to the IP address, you need to set a subnet mask. All networks
are divided into smaller sub-networks and a subnet mask is a number
that enables a device to identify the sub-network to which it is
connected.
62
APPENDIX B: IP ADDRESSING
For your network to work correctly, all devices on the network must have:
■
The same sub-network address.
■
The same subnet mask.
The only value that will be different is the specific host device number.
This value must always be unique.
An example IP address is ‘192.168.100.8’. However, the size of the
network determines the structure of this IP Address. In using the Access
Point, you will probably only encounter two types of IP Address and
subnet mask structures.
Type One
In a small network, the IP address of ‘192.168.100.8’ is split into two
parts:
■
Part one (‘192.168.100’) identifies the network on which the device
resides.
■
Part two (‘.8’) identifies the device within the network.
This type of IP Address operates on a subnet mask of ‘255.255.255.0’.
See Table 3 for an example about how a network with three computers
and a Access Point might be configured.
Table 3 IP Addressing and Subnet Masking

255.255.255.0
Access Point
192.168.100.72
255.255.255.0
Type Two
In larger networks, where there are more devices, the IP address of
‘192.168.100.8’ is, again, split into two parts but is structured differently:
■
Part one (‘192.168’) identifies the network on which the device
resides.
■
Part two (‘.100.8’) identifies the device within the network.
How does a Device Obtain an IP Address and Subnet Mask?
63
This type of IP Address operates on a subnet mask of ‘255.255.0.0’.
See Table 4 for an example about how a network (only four computers
represented) and a Access Point might be configured.

255.255.0.0
There are three different ways to obtain an IP address and the subnet
mask. These are:
■
Dynamic Host Configuration Protocol (DHCP) Addressing
■
Static Addressing
■
Automatic Addressing (Auto-IP Addressing)
The Access Point contains a DHCP server, which allows computers on
your network to obtain an IP address and subnet mask automatically.
DHCP assigns a temporary IP address and subnet mask which gets
reallocated once you disconnect from the network.
DHCP will work on any client Operating System such as Windows® 95,
Windows 98 or Windows NT 4.0. Also, using DHCP means that the same
IP address and subnet mask will never be duplicated for devices on the
network. DHCP is particularly useful for networks with large numbers of
users on them.
Static Addressing
Auto-IP Addressing
You must enter an IP Address and the subnet mask manually on every
device. Using a static IP and subnet mask means the address is
permanently fixed.
Network devices use automatic IP addressing if they are configured to
acquire an address using DHCP but are unable to contact a DHCP server.
Automatic IP addressing is a scheme where devices allocate themselves
64
APPENDIX B: IP ADDRESSING
an IP address at random from the industry standard subnet of
169.254.x.x (with a subnet mask of 255.255.0.0). If two devices allocate
themselves the same address, the conflict is detected and one of the
devices allocates itself a new address.
Automatic IP addressing support was introduced by Microsoft in the
Windows 98 operating system and is also supported in Windows 2000.

GLOSSARY
802.11b
10BASE-T
The IEEE standard to which the 3Com OfficeConnect 11Mpbs Wireless
Access Point conforms. This standard provides for 1,2,5.5 and 11 Mbps
data rates and a set of fundamental signaling methods and other services
(see WECA).
The IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5
twisted pair cable.
100BASE-TX
The IEEE specification for 100 Mbps Fast Ethernet over Category 5
twisted-pair cable.
Access Point
An Access Point is a device through which wireless clients connect to
other wireless clients and which acts as a bridge between wireless clients
and a wired network, such as Ethernet. Wireless clients can be moved
anywhere within the coverage area of the access point and still connect
with each other. If connected to an Ethernet network, the access point
monitors Ethernet traffic and forwards appropriate Ethernet messages to
the wireless network, while also monitoring wireless client radio traffic
and forwarding wireless client messages to the Ethernet LAN.
Ad Hoc mode
Ad Hoc mode is a configuration supported by most wireless clients. It is
used to connect a peer to peer network together without the use of an
access point. It offers lower performance than infra-structure mode,
which is the mode the gateway uses. (see also Infra-structure mode.)
Auto-negotiation
Some devices in the OfficeConnect range support auto-negotiation.
Auto-negotiation is where two devices sharing a link, automatically
configure to use the best common speed. The order of preference (best
first) is: 100BASE-TX full duplex, 100BASE-TX half duplex, 10BASE-T full
duplex, and 10BASE-T half duplex. Auto-negotiation is defined in the IEEE
76
GLOSSARY
802.3 standard for Ethernet and is an operation that takes place in a few
milliseconds.
Bandwidth
The information capacity, measured in bits per second, that a channel can
transmit. The bandwidth of Ethernet is 10 Mbps, the bandwidth of Fast
Ethernet is 100 Mbps. The bandwidth for 802.11b wireless is 11Mbps.
Category 3 Cables
One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586
standard. Category 3 is voice grade cable and can only be used in
Ethernet networks (10BASE-T) to transmit data at speeds of up to 10
Mbps.
Category 5 Cables
One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586
standard. Category 5 can be used in Ethernet (10BASE-T) and Fast
Ethernet networks (100BASE-TX) and can transmit data up to speeds of
100 Mbps. Category 5 cabling is better to use for network cabling than
Category 3, because it supports both Ethernet (10 Mbps) and Fast
Ethernet (100 Mbps) speeds.
Channel
Similar to any radio device, the OfficeConnect 11Mbps Wireless Access
Point allows you to choose different radio channels in the wireless
spectrum. A channel is a particular frequency within the 2.4GHz
spectrum within which the Gateway operates.
Client
The term used to described the desktop PC that is connected to your
network.
DHCP
Dynamic Host Configuration Protocol. This protocol automatically assigns
an IP address for every computer on your network. Windows 95,
Windows 98 and Windows NT 4.0 contain software that assigns IP
addresses to workstations on a network. These assignments are made by
the DHCP server software that runs on Windows NT Server, and Windows
95 and Windows 98 will call the server to obtain the address. Windows
98 will allocate itself an address if no DHCP server can be found.
DNS Server Address
DNS stands for Domain Name System, which allows Internet host
computers to have a domain name (such as 3com.com) and one or more
IP addresses (such as 192.34.45.8). A DNS server keeps a database of
host computers and their respective domain names and IP addresses, so
that when a domain name is requested (as in typing “3com.com” into
GLOSSARY
77
your Internet browser), the user is sent to the proper IP address. The DNS
server address used by the computers on your home network is the
location of the DNS server your ISP has assigned.
Encryption
A method for providing a level of security to wireless data transmissions.
The OfficeConnect 11Mbps Wireless Access Point uses two levels of
encryption; 40/64 bit and 128 bit. 128 bit is a more powerful level of
encryption than 40/64 bit.
ESSID
Extended Service Set Identifier. The ESSID is a unique identifier for your
wireless network. You must have the same ESSID entered into the Access
Point and each of it's wireless clients.
Ethernet
Ethernet Address
Fast Ethernet
A LAN specification developed jointly by Xerox, Intel and Digital
Equipment Corporation. Ethernet networks use CSMA/CD to transmit
packets at a rate of 10 Mbps over a variety of cables.
See MAC address.
An Ethernet system that is designed to operate at 100 Mbps.
Firewall
Electronic protection that prevents anyone outside of your network from
seeing your files or damaging your computers.
Full Duplex
A system that allows packets to be transmitted and received at the same
time and, in effect, doubles the potential throughput of a link.
Half Duplex
A system that allows packets to transmitted and received, but not at the
same time. Contrast with full duplex.
Hub
A device that regenerates LAN traffic so that the transmission distance of
that signal can be extended. Hubs are similar to repeaters, in that they
connect LANs of the same type; however they connect more LANs than a
repeater and are generally more sophisticated.
IEEE
Institute of Electrical and Electronics Engineers. This American
organization was founded in 1963 and sets standards for computers and
communications.
78
GLOSSARY
IETF
Internet Engineering Task Force. An organization responsible for
providing engineering solutions for TCP/IP networks. In the network
management area, this group is responsible for the development of the
SNMP protocol.
Infra-structure mode
Infra-Structure mode is the 802.11b configuration supported by the
Access Point. You will need to ensure all of your clients are set up to use
infra-structure mode in order for them to communicate with the Access
Point. (see also Ad Hoc mode)
IP
Internet Protocol. IP is a layer 3 network protocol that is the standard for
sending data through a network. IP is part of the TCP/IP set of protocols
that describe the routing of packets to addressed devices. An IP address
consists of 32 bits divided into two or three fields: a network number and
a host number or a network number, a subnet number, and a host
number.
IP Address
Internet Protocol Address. A unique identifier for a device attached to a
network using TCP/IP. The address is written as four octets separated with
periods (full-stops), and is made up of a network section, an optional
subnet section and a host section.
ISP
Internet Service Provider. An ISP is a business that provides connectivity to
the Internet for individuals and other businesses or organizations.
LAN
Local Area Network. A network of end stations (such as PCs, printers,
servers) and network devices (hubs and switches) that cover a relatively
small geographic area (usually not larger than a floor or building). LANs
are characterized by high transmission speeds over short distances (up to
1000 metres).
MAC
Media Access Control. A protocol specified by the IEEE for determining
which devices have access to a network at any one time.
MAC Address
Media Access Control Address. Also called the hardware or physical
address. A layer 2 address associated with a particular network device.
Most devices that connect to a LAN have a MAC address assigned to
them as they are used to identify other devices in a network. MAC
addresses are 6 bytes long.

interchangeably with ESSID.
Subnet Address
An extension of the IP addressing scheme that allows a site to use a single
IP network address for multiple physical networks.
Subnet mask
A subnet mask, which may be a part of the TCP/IP information provided
by your ISP, is a set of four numbers configured like an IP address. It is
used to create IP address numbers used only within a particular network
(as opposed to valid IP address numbers recognized by the Internet,
which must assigned by InterNIC).
Subnets
Switch
A network that is a component of a larger network.
A device that interconnects several LANs to form a single logical LAN that
comprises of several LAN segments. Switches are similar to bridges, in
that they connect LANs of a different type; however they connect more
LANs than a bridge and are generally more sophisticated.
