Troubleshooting Wireless Print Servers - HP Jetdirect 640n Administrator's Manual

Troubleshooting wireless print servers

Unable to communicate during initial setup
If you use wireless communications to set up the print server, verify the following:
●
Your wireless computer is configured to match the default wireless network settings on the
HP Jetdirect print server:
Communication Mode: Ad Hoc
❑
Network Name (SSID): hpsetup
❑
Encryption (WEP): <Disabled>
❑
NOTE:
lowercase characters.
●
The HP Jetdirect print server is turned on and operating properly (print the configuration page).
●
You are within range of the HP Jetdirect print server.
●
There are fewer than six devices total on the ad hoc network (with SSID "hpsetup").
●
There is no access point in the vicinity that is configured with an SSID of "hpsetup".
●
Multiple print servers are not being configured at the same time. If there are multiple print
servers, turn all off except the one you want to configure.
Unable to communicate after initial setup
If you have successfully configured the HP Jetdirect wireless print server with a network connection to
your network, but your network computers are unable to communicate with the printer (including a
ping command), try the following:
●
Print an HP Jetdirect configuration page and verify all configuration settings for your network.
Common errors include incorrect entries for the following items:
❑ Communication Mode (Ad Hoc or Infrastructure)
Network Name (SSID), which is case-sensitive
❑
Authentication method
❑
Encryption type, encryption key entries, or the specified transmit key
❑
IP address
❑
Basic service set identifier (BSSID), which distinguishes one wireless LAN from another
❑
even though they have the same SSID
●
Verify that the printer is within range of the network. See
on page
●
Use a wireless PC and its utilities to confirm the signal strength at the printer's location. The
detected signal strength should be similar for the print server, as indicated on the HP Jetdirect
configuration page.
