    Reseat the temporary installation cable on both ends, see check #2, 'AP Wireless Router Settings', and refer to the instructions  for Infrastructure or Ad hoc installation.
    Settings and values of importance include: 

    • BSS type - Ad hoc or Infrastructure  

    • SSID - Network Name

    • Channel - 1-14 depending on geography

    • Security - Case-sensitive values (WEP, WPA, WPA2)

    • Wireless radio - Turned ON

    • Broadcast SSID - Disabled during configuration of the printer

    • MAC filtering - Disabled during configuration, or UAA address of printer should be added to the list of allowed MAC addresses.  Printer UAA = MAC address. 

    • AP firewall - Disabled during configuration of the printer.

    • Software firewall - Disabled during configuration, or make sure to select ALWAYS grant permissions during the configuration of the printer.

    Please refer to your wireless router documentation for detailed information on advanced AP settings. AP web-page settings differ in location and nomenclature based on the manufacturer.     
    NOTE:  It's important to verify that there is a solid green WiFi indicator light and a secure temporary installation cable connection during the configuration of this product.   
    Communication error message during configuration. 
    Reseat the temporary installation cable on both ends, see check #2, 'AP Wireless Router Settings', and refer to the instructions  for Infrastructure or Ad hoc installation. See also 'Printer adapter not found' above.

    Printer has never been configured.

    • For infrastructure mode, click here.

    • For ad hoc mode, click here.
    Access point out of range and other possibilities.  
    Move the printer closer to the access point.  See 'Signal Strength' and 'Quality' below.
    Post-configuration possibility: Interference caused by obstructions or other radio frequency (RF) devices in the vicinity of the printer or network.
    Other considerations include RF shadow: This phenomenon occurs when a physical obstruction is hindering the printer's ability to pick up a strong signal.  
    If moving the access point (AP) is not possible, consider changing channels on the AP or purchasing a higher gain antenna for the AP.   
    Network cable has become detached.  Wired Mode

    • Verify the status and activity lights  above the printer's Ethernet port.  View larger image

    • Try an alternative Ethernet cable.

    • Try alternative port on hub, router or switch.

    • Try a direct connection using a crossover cable. 

    • Follow the checks starting with 'Access Point Settings'.

     


    1. TCP/IP 


      • Address - This is the IP address of the printer.

      • Gateway - This value is usually the address of your wireless router, or the address used to access your wireless router's web page. 
         

    2. SSID -  This is the access point's network name as transferred from the access point to the printer during the installation process.
      NOTE:  Even if no security (WEP, WPA, WPA2) is implemented on the AP, you still have to confirm that the printer's SSID value is equivalent to the AP.  This setting may be at 'default', or 'linksys', or some other default value; however, it is still crucial to know what this value is. 
      AP = Access Point (Wireless Router)
       

    3. Signal Strength and Quality - Unacceptable or poor values for these settings could prevent the printer from communicating properly on the network.

Suggestions for low signal strength issue include

  • Reposition the antennas on the printer and the AP.

  • Change the location of the printer.

  • Change the transmit channel on the AP. 

  • Move or remove any possible physical obstruction.

  • Remove or turn off device causing possible RF interference.

  • If capable, adjust (increase or decrease) the power level on your AP.  

  • Purchase of high-gain antennas for the AP. 

See also  'Access Point out of range' above.   
NOTE:  A range of 100 - 150 feet is optimal; however, 300 feet is possible depending on location and level of interference (e.g. 2.4GHz cordless phones). 

2.  Access Point Settings
(wireless router)

 
Click here for instructions.
NOTE:  These instructions are intended as an example only; please refer to your wireless router documentation for detailed information.
 
 

Verify the access point values, and compare these values with the printer's network settings page.  
IMPORTANT! If the printer has already been configured, SSID and channel values should be identical and IP parameters should be almost identical.  If the printer has not been configured, see 'Reference: Default Wireless Settings' below.      
Settings and Values of importance include: 

  • BSS type - Ad hoc or Infrastructure  

  • SSID - Network Name

  • Channel - 1-14 depending on geography

  • Security Key - Case-sensitive values (WEP, WPA, WPA2) not shown on settings page, but value is critical to successful wireless communication. 

  • Address - Different but similar addresses should be observed.

  • Subnet - Identical values should be observed.

  • Gateway - AP gateway will be different.
    NOTE:  The printer's setting page gateway address value is also the IP address of the router in most installation scenarios.    

  • Wireless radio - Turned ON

Please refer to your wireless router documentation for detailed information on the advanced AP settings mentioned below. AP web-page settings differ in location and nomenclature based on manufacturer, model, and firmware revision.
Advanced AP Settings

  • Broadcast SSID - Disabled during printer setup and configuration.

  • MAC filtering - Disabled during printer setup and configuration, or UAA address of printer should be added to list of allowed MAC addresses.  Printer UAA = MAC address. 

  • AP firewall - Disabled during configuration of the printer.    

Questions of importance include:

  • Is the PC or workstation communicating wirelessly using a WiFi network adapter installed on the PC or workstation? 

If YES, an inability to access the access point web page could also answer your question as to why the printer is unable to communicate over the network.
If NO, your PC or workstation is connected to the access point (AP) via an Ethernet cable, and access to the AP web page is being performed over a wired connection.  It is recommended that you verify communication of other wireless devices. 
NOTE:  If NO, and you are connected via Ethernet cable to the AP, accessing the router's web page will not validate any form of wireless communication.   

3.  Computer's TCP/IP Settings
Click here for instructions.
 

Check your computer's IP parameters, and make sure the IP address is similar to, but not the same as, the wireless router's IP address and the printer's IP address.
parameters = address, netmask (subnet), and gateway.

4.  View Printer's Web Page
Click here for instructions.
Enter the printer's TCP/IP address into the web browser's address field (i.e. http://printer's_IP address, where <printer's_IP address> is the address under TCP/IP of the network settings page. 

5.  Ping Printer & Access Point
Click here for instructions. 
Ping the printer's IP address, and also ping the access point's IP address and gateway.
