3. Enable AMSDU Aggregation: Select this option to enable Aggregated Mac Service Data Unit (A-MSDU),
which increases the maximum size of the frame transmission from 2,304 bytes to 7,935 bytes. This
option applies only to the 802.11n wireless mode.
NOTE: You can use the Enable AMSDU Aggregation and Enable AMPDU Aggregation options
separately or together.
4. Enable AMPDU Aggregation: Select this option to enable Aggregated Mac Protocol Data Unit (A-MPDU),
which allows a maximum size of the frame transmission of 64 KB. This option applies only to the
802.11n wireless mode.
5. Enable Block ACKs: Select this option to enable block acknowledgements (ACKs), which allow each of
the aggregated data frames to be individually acknowledged or retransmitted if an error occurs. This
option applies only to the 802.11n wireless mode.
In the Communications section, specify the following options:
1. Network name (SSID): Enter the Service Set Identifier (SSID) to which the HP Jetdirect print server
connects. The SSID identifies the extended service set (ESS) that is normally associated with larger
networks in Infrastructure mode. The SSID is case sensitive.
The print server lists the detected SSIDs. An empty (or blank) Network name (SSID) field is acceptable
for networks that rely on the signal strength, encryption, and authentication methods to control
network access.
The factory default SSID configured on the HP Jetdirect print server is hpsetup. To initially communicate
with the print server, the SSID for the wireless device must also be hpsetup.
2. Infrastructure (access point): Select this option to allow wireless devices on the network to
communicate by using an access point. To connect to the network, the settings on the wireless device
must match the wireless connection settings for the access point. Select this option if the wireless
devices must be in Infrastructure mode.
3. Ad-hoc (peer-to-peer): Select this option to allow wireless devices on the network to communicate
directly with each other. Other terms used for Ad hoc mode include Independent Basic Service Set (IBSS)
and Computer-to-Computer mode. Ad hoc mode is the factory default configured on the HP Jetdirect
print server.
Channel: Select the radio frequency the print server uses to broadcast its availability if it fails to
associate with the specified ad hoc network on any channel. The factory default is channel 11
(2462 MHz). Channel 10 (2457 MHz) is also available. To initially communicate with the print server, the
wireless device must be configured for Ad hoc mode.
In the Authentication and Encryption section, specify the following options:
1. No authentication or encryption: Select this option if device authentication or security is not required
to access the wireless network.
NOTE: The network might continue to use WEP encryption keys for data privacy.
2. WEP (Wired Equivalent Privacy):
●
Authentication: Indicates the authentication mode for the specified WEP settings.
●
WEP-Personal: Select this option if the devices on the wireless network use a shared encryption
key (or a shared password value) for network access and communication. Each device on the
network must use the same key. The HP Jetdirect print server supports IEEE 802.11 WEP keys for
encrypted network communications. If you select this option, specify the following settings to
configure the WEP key:
