The 150wl (802.11b AP card) supports the following wireless LAN features:
■The 802.11b AP card is Wi-Fi (Wireless Fidelity)
certified by the Wireless Ethernet Compatibility
Alliance (WECA). This means that your 802.11b AP
card will communicate with other vendors’ IEEE 802.11b compliant
wireless LAN products.
■Fully compatible with any other wireless LAN system based on
Direct Sequence Spread Spectrum (DSSS) radio technology that
complies with the IEEE 802.11 standard on wireless LANs.
■Supports all 802.11b data rates in the transmit range of 11, 5.5, 2 and
1 Mbps.
■Supports Automatic Frequency Channel Selection (2.4 GHz)
allowing roaming over multiple channels.
■128-bit RC4 data encryption (also supports 64-bit RC4/Wired
Equivalent Privacy - WEP).
The 170wl (802.11g AP card) supports the following wireless LAN features:
■Fully compatible with any other wireless LAN system based on
Direct Sequence Spread Spectrum (DSSS) and Orthogonal
Frequency Division Multiplexing (OFDM) radio technology that
complies with the IEEE 802.11 standard on wireless LANs.
■Supports all 802.11g data rates in the transmit range of 54, 48, 36, 24,
18, 12, 9 and 6 Mbps. The 802.11g AP card also supports the 802.11b
data rates.
■Supports Automatic Frequency Channel Selection (2.4 GHz)
allowing roaming over multiple channels.
■128-bit RC4 data encryption (also supports 64-bit RC4/Wired
Equivalent Privacy - WEP).
■Closed system support. This feature prevents wireless client access
without the configured wireless network name.
■VLAN 16 with multiple SSIDs, extends support for compatibility with
VLAN enabled wired networks by providing the user with the
capability to configure up to 16 Network Names or SSIDs, and 16
corresponding VLAN identifiers per AP card.
■Secure Socket Layer (SSL) Browser support is an enhancement to
the already existing HTTP management interface of the AP. This
functionality will allow secure communication between the AP and

■Rogue AP detection will provide the ability to detect unauthorized
APs within a given coverage area. When enabled, the AP will scan
the range of coverage and identify the active APs in the area.
■SNMPv3 support is for supporting the Simple Network Management
Protocol version 3. The SNMPv3 feature is based on existing SNMP
framework, but addresses security requirements for device and
network management.
■Tx Power Control is an implementation of transmit power control
by using standard 802.11d frames to control transmit power. The AP
will allow four intervals of transmit power control: 100% (Regulatory
Maximum), 50%, 25%, and 12.5%.
■Monitoring Station Statistics provides the capability to monitor a set
of statistics for all active stations connected to an AP. A user can
enable this feature and view statistics such as: IP address, MAC
address, interface, station type, protocol, and so forth.
■HTTPS file transfer is an enhancement to the already existing HTTP
management interface of APs. This functionality will allow transfer
of configuration and kernel image files to and from the AP from any
compliant HTTP/HTTPS browser.
■Auto configuration by DHCP server will allow for auto configuration
of the AP devices in a given subnet to include an IP address and basic
configuration.
■Multiple RADIUS authentication server support extends the existing
authentication server configuration option available in APs. A user
can configure separate primary and secondary servers for RADIUS
and 802.1x servers that can be used for MAC based or 802.1x
authentication, respectively. This also extends the server fallback
capability to the new servers supported.

Troubleshooting
Common Situations
If you encounter difficulty using and/or installing these cards in your Access
Point, the error may be related to various causes:
■The cards are not firmly inserted into the card slot.
■Client is out of range (too far away from the access point). This
prevents the cards from establishing a wireless connection with the
client.
■Configuration mismatch, which prevents clients from establishing a
wireless connection with the access point.
The configurations for the AP and the client may be different in some
way, perhaps due to the wrong kind of radio or an improper setting in
the configuration for one of the two devices.
Most configuration problems can be fixed by changing the settings for the
520wl Access Point using the browser-based interface. Configuration prob-
lems may include:
■SSID (Service Set Identification) misspelled
■IP Configuration (Static IP is incorrect). If you did not use auto
configuration by DHCP server, then check configuration parameters
to ensure they are correct.
■VLAN (May exclude your Access Point)
■Password Settings
■Management Services Settings (SNMP, Telnet, CLI, and HTTP)
■Intra-BSS Traffic Operation set to Block
■Security Settings (WEP Encryption Keys, 802.1x, MAC Access)

LED Activity
The starting point to troubleshoot problems with the card inserted into your
Access Point is looking at the LED activity of the card.
The following table provides an overview of the various modes of operation
and the associated LED activity. It also includes a number of trouble-
shooting hints, that may help solve the problem.
LED Activity
Power LED Radio LED Description/Action
Continuous
Green
Blinking Standard operational mode.
Card is powered on.
Sensing/transmitting wireless data.
Off Card is powered on.
No wireless activity.
No action is required.
Off Off Card is not powered on, so it can not transmit/receive
data.
The cause may either be:
• AP Card is not fully inserted into the slot
• AP is not receiving power (LEDs on the AP are not lit)
150wl+170wl-QIG-ed2.book Page 10 Friday, March 26, 2004 12:04 PM

11
Clients Cannot Connect to the Access Point
Here are some possible causes if clients are not able to connect to the access
point.
Configuration Mismatch
Frequent configuration mismatches involve the following items:
■Network Name
The 802.11b and 11g AP Cards Network Name is case-sensitive. Each
wireless AP Card in the HP 520wl should have a unique Network Name.
This Network Name must match the active Network Name on client
machines. The client software allows you to store Network Names in
configuration profiles, then you can select a profile to fit your location.
Network Names should be allocated and maintained by the Network
Administrator.
■Encryption Key
If you have set a WEP encryption key in the 520wl configuration, the
client wireless PC card must be configured to use the same key.
Client PC Card Does Not Work
1. Ensure you are using the latest PC Card driver software.
2. Download and install the latest client software.
3. Refer to the documentation that came with your client cards for addi-
tional troubleshooting suggestions.
Intermittent Loss of Connection
1. Ensure the client is within range of the HP 520wl. For more information
regarding range see the Range/Transmit Rate chart on page 16.
2. The signal strength can be checked by using the signal strength gauge
from the client software.
150wl+170wl-QIG-ed2.book Page 11 Friday, March 26, 2004 12:04 PM

12
Client Does Not Receive an IP Address - Cannot Connect to
Internet
1. If the HP 520wl is configured as a DHCP server, open the Web-browser
Interface and select the Configure button, then the Network tab and then
the DHCP Server tab to ensure the proper DHCP settings are being used.
2. If you are using the DHCP feature on the HP 520wl, then ensure your
local DHCP server is operating on the same subnet mask as your
HP 520wl.
NOTE:
For more information regarding DHCP Server settings, see the HP 520wl
User’s Guide.
3. From the client computer, use the ping network command to test the
connection with the HP 520wl. If the HP 520wl responds, but you still
cannot connect to the Internet, there may be a physical network config-
uration problem.
150wl+170wl-QIG-ed2.book Page 12 Friday, March 26, 2004 12:04 PM

13
Other Problems
If you are unable to fix problems with the 802.11b and 11g AP Card using
the suggestions in this chapter, you may want to try resetting the AP to
factory default settings.
■On the 520wl Access Point hold the RESET button down for 5
seconds.
■Turn the power off and back on again to reboot the Access Point.
■In some cases you may need to reboot your computer or clients as
well.
■Check the documentation that came with the client wireless cards
for other troubleshooting procedures for those cards.
If you are still having problems with the 802.11b and 11g AP Card and you
have not been able to fix them with the Troubleshooting suggestions from
this booklet, please refer to the more detailed instructions in the Trouble-
shooting chapter of the HP 520wl User Guide.
