Improving reception and performance
Wireless LAN radio signals can penetrate many indoor structures and can reflect around obstacles.
However, wireless communication range and performance depends on a variety of factors, including
the number of users, the quality and physical placement of the wireless hardware, and the sources of
radio signal interference. For example, microwave ovens and cordless telephones use similar
frequencies that can interfere with wireless LAN signals. In general, the HP Jetdirect wireless print
server's data transfer rates decrease with increasing distance, obstructions and interference.
Symptoms
●
The signal strength is poor or marginal. See the HP Jetdirect configuration page or embedded Web
server.
●
Print jobs are excessively slow.
Corrective actions
●
Re-orient the printer or HP Jetdirect wireless print server. In general, having the print server pointed
toward the access point or wireless PC improves reception and performance.
●
Reduce or remove sources of interference. Metallic objects can absorb or attenuate radio signals,
and devices such as microwave ovens and cordless phones operate using similar radio
frequencies.
●
Reduce the distance between the printer and the access point or wireless PC by doing any of the
following:
moving the printer
❑
moving the access point or wireless PC
❑
adding an additional access point (Infrastructure mode only)
❑
●
Elevate the access point's antenna. In most office environments, elevating the access point's
antenna improves the range and performance of all wireless devices.
Firmware download failure
As with other HP Jetdirect print servers, firmware upgrades can be downloaded using tools such as HP
Download Manager (Windows), HP Web Jetadmin, or file transfer protocol (FTP).
If a firmware download failure occurs on an HP Jetdirect wireless print server, simply restart the
download process and try again. If it is turned off and then on, the print server regains its previous
configuration prior to the download failure.
