Choice of operating mode
Tests have shown that performances obtained in Infrastructure mode are the
same as those obtained in Ad Hoc mode. The same is true for encryption: as
the radio card carries this out independently, any main link debit will not be
affected.
Once the antenna alignment is completed, it is recommended to switch to
Infrastructure mode (one Hyperlan-Pack system configured in access point,
the other in bridge infrastructure) in order to allow for higher security settings
(access to WPA encryption and MAC address filtering).
To maximize performance we recommend the following configuration:
-
Infrastructure mode
-
Super A mode without turbo
Selection of either Infrastructure mode or Super A mode can be found in the
‘Basic Wireless’ option of the Web administration tool, accessible by NDM or
by using an Internet browser (Firefox, internet explorer…).
WARNING: when switching from Ad Hoc mode to Access Point mode, the
distance parameter between the two antennas is lost. It must therefore be
reconfigured.
USE
10. Modifying device’s parameters
Via the integrated web management interface, set the following main
parameters:
-
The operating mode: Ad hoc or Infrastructure
-
Wi-Fi security parameters (WEP, WPA…)
-
The IP addresses of the Hyperlan-Pack modules
-
The ‘distance’ parameter (distance between the antennas)
-
Integrated SNMP agent setup
-
Radio channel to use (in the 802.11a range)
11. SNMP
Administration
The two Hyperlan-Pack modules can be configured and monitored using the
SNMP protocol (V1 or V2c). The ACKSYS enterprise MIB is available at:
http://www.acksys.fr/Logiciels%20&%20Drivers/ACKSYS-WLG-MIB.zip
TROUBLESHOOTING
All 8 LEDs indicators are OFF
-
Verify the power supply (Voltage, cabling).
The relevant LAN1 or LAN2 led indicator stays OFF
-
Verify the Ethernet plug of your network; try to connect another device.
-
Connect the device with the ACKSYS M12/RJ45 cable.
The wireless link does not connect:
-
Check the radio connections: position and orientation of the antennas,
radio wave obstacles, radio channel interference
-
Run a second antenna alignment check.
-
Try another radio channel.
-
Check the state of the lightning arrestor capsule.
“ACKSYS NDM” doesn’t find your device
-
ACKSYS NDM only scans the local network. Devices located behind a
gateway are not seen.
-
If you use a firewall on your P.C, check if the application is not blocked.
