Wireless Signal Weak or Failed 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 may interfere with wireless LAN signals). In general, the HP Jetdirect wireless print server's data transfer rates will decrease with increasing distance, obstructions and interference. For these Symptoms: z Wireless/Status light appears yellow or remains slowly blinking green (see the table of status lights on page 5-2) z On the configuration page (see page 5-4), Signal Strength is poor or marginal. z Print jobs are excessively slow or interrupted. Try these Actions: z Re-orient the print server around the printer (limited by the length of its USB cable, of course). In general, having the print server pointed toward the access point or wireless PC will improve reception and performance. z 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. z Reduce the distance between the print server and the access point or wireless PC. This can be accomplished by: „ moving the print server, and the printer if necessary. „ moving the access point or wireless PC „ adding an additional access point (infrastructure mode only) Troubleshooting Problems 5-9

Troubleshooting Problems 5-9
Wireless Signal Weak or Failed
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 may interfere with wireless LAN signals).
In general, the HP Jetdirect wireless print server’s data transfer rates will decrease with
increasing distance, obstructions and interference.
For these Symptoms:
Wireless/Status
light appears yellow or remains slowly blinking green (see the table
of status lights on page 5-2)
On the configuration page (see page 5-4), Signal Strength is poor or marginal.
Print jobs are excessively slow or interrupted.
Try these Actions:
Re-orient the print server around the printer (limited by the length of its USB cable, of
course). In general, having the print server pointed toward the access point or wireless
PC will improve 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 print server and the access point or wireless PC.
This can be accomplished by:
moving the print server, and the printer if necessary.
moving the access point or wireless PC
adding an additional access point
