  ”Connection Failed”

  The computer and other devices are able to communicate on the wireless network; however, you cannot setup or install the printer.

  IMPORTANT! A computer connected via an Ethernet wired connection is different from a computer communicating over a wireless network. Hence, you must verify what other wireless devices are communicating with your router; e.g., any 802.11 g/b/n-equipped laptop, e-reader, smartphone, television, or other device.

  Before you begin

  If you receive this error at the time of initial setup and you are configuring the printer with a USB cable and the Lexmark Wireless Setup Utility, you will not be able to proceed until you know your router’s configured security parameters.



  User-assigned KEY or PASSPHRASE

  See the checklist below for more information. You will obtain these values from your router. NOTE: Lexmark is not responsible for supplying these values.

  Router Configuration Setting Checklist

  Possible “Connection Failure” causes

  Possible actions

  Incorrect SSID (Network Name) selected

  Note: You or someone that configured your network should know this name. Otherwise, a default service set identifier (SSID) or network name was provided by the router manufacturer.

  During software installation, an incorrect network name or a duplicate name (SSID) was selected.

  Try selecting the correct network name, or select a different duplicate network name.

  Hint! You may want to consider the Wireless Setup Utility’s displayed signal strength in your determination.

  Warning! The strongest signal is not always your network(name). Be careful when selecting your network name, especially in congested areas.

  Incorrect Security Type (Manual entry cases only)

  Make sure you know if you are using WEP, WPA, or WPA2. See router’s configuration web page or software configuration utility.

  2007 Printer/All-In-One note: Only if using an older printer should you have to be concerned about TKIP vs. AES. It is suggested that the router/WSU setting (TKIP + AES) not be selected. Choose AES if using WPA2 and use TKIP is using WPA.

  Incorrect entry of security key or passphrase

  Re-enter the proper passphrase.

  Note: Remember that entry of passphrases are sensitive to:




  Special characters, and

  The number and types of characters.

  For example: Test_1(space)2009@home

  Verify passphrase character length per security encryption type via router:

  Hints! Watch out for extra spaces. You may be one character under, or one character over, the acceptable limit.

  Check your router configuration software or web configuration page for exact passphrase value.

  WEP – Exactly 5 or 13 keyboard characters, or exactly 10 to 26 hexadecimal digits using a combination of A-F and 0-9. Hint! 13 characters yields 26 hex digits.

  WPA or WPA2 – 8 to 63 characters

  Warning! If you cannot resolve the correct key or passphrase, you will have to perform a complete restore/reset of the router’s factory defaults, and you may have to reconfigure more than one wireless device on your network.

  Other Router/Access Point Considerations

  Note: For the following, you may have to contact or reference your router manufacturer’s different support options.

  DHCP (off)

  Turn on the DHCP router setting. DHCP(off) will prevent the printer from obtaining an IP address.

  Media Access Control (MAC) address filtering (on)

  Note: Router naming convention for this feature varies.

  This additional security measure on the router will have to include the printer’s MAC/UAA 12-digit address be set to NOT BLOCKED.

  Router running on the 5 GHz band

  Make sure the router is using the 2.4 GHz band.

  Other considerations


  Firewall blocking communication

  Firewalls or security software applications often create the majority of communication issues. They come in many forms:

  Third party software firewall or security applications

  BIOS or system firewalls

  Router firewalls

  Operating system firewalls

  Create exceptions, or select Allow always if prompted with a balloon pop-up window that references some form of a (Lx…exe) process, or

  Click here for firewall, processes, and port information which may help resolve this communication problem.

  Contact your firewall manufacturer if you are unsure how to manage your firewall’s allow/exceptions list.

  Virtual Private Networks (VPN) (“Connection failed” or “Communication Failure” may result)

  Disconnect from your VPN when configuring the printer. Consider VPN split tunneling options with your workplace network administration or IT departments.

  Distance and interference

  Reposition printer closer to the router, or

  Readjust router or printer antennas (if equipped with antennas).

  Remedy steps




  Turn off ALL security software applications and firewalls and run the wireless setup utility again. You can find the WSU under Lexmark Printer Home or in your Lexmark program group items.


  Click here to access additional “firewall” and “Connection Failed” related topics.


  Make sure the processes required by the printer to communicate are located in your firewall’s exception list.


  Also, locate the following processes and select “grant full access”, or “grant always”.

  NOTE: Click here for more information on processes and executables utilized by the Inkjet Products. The differs by printer model. For example, a Lexmark Pro205 will have a prefix of , so the name for the communications process will appear as Lxebcoms.exe.

  IMPORTANT! Any blocked process will prevent communication to the printer. Contact your firewall manufacturer’s technical support resources if you are unsure how to create exceptions or grant access to these processes.

  Communication Failure

  The more common reasons for this error all result in a loss of printer communication.

  Your computer is also not communicating over your network.

  You received a new printer. See solid orange recommendations.

  You purchased a new or different wireless router.

  You performed a full reset of the router because you forgot the security key/passphrase.

  You performed a full reset of the router because you forgot the password to the router’s web interface.

  You moved the printer to a new or different network.

  Firewalls. See above topics under Connection Failed.

  You intentionally changed your router’s SSID or security parameters (Network Name – SSID; Encryption-security type; key or passphrase).

  If any of the above statements are true, then run the Wireless Setup Utility to re-join the network. NOTE: This is found under Lexmark Printer Home for current printers.

  Biggest culprits include:

  Obstructions such as any object that absorbs, reflects, refracts, diffuses, blocks or scatters radio waves

  Distance; e.g., average range is ~70-150 feet or ~21-48 meters.

  RF Interference; e.g., any wireless device running in the 2.4GHz wavelength frequency spectrum

  Antenna placement: recommendation: horizontal antenna placement for printers above and below router, or vertical/angled antenna if printer sits on the same plane as the router

  Printer placement; e.g., closet

  Proprietary speed boost modes on routers; see router manufacturer for 802.11b/g/n mixed mode compliancy

  Router’s radio switched to 5GHz band; Lexmark printers currently only accept the 2.4GHz band.

  Alternate Actions




  See Steps listed above for a “connection failed” error, or look for a network related communication problem. See other “Communication not Available” topics in the Installation and Networking Troubleshooting Table of Contents.


  Continue to investigate the Trouble code or possible reasons for sacrificed wireless signal strength.


  See Router/Network Configuration Setting Checklist above for additional reference.

  ”Test and Actions” Decision Table



  Yes, you can ping the printer’s TCP/IP address…

  Perform operating system checks to see other possible solutions.

  Try to recreate the printer port. Click here for Microsoft Windows instructions. See Related Information for possible additional topics that pertain to port selection.

  See Table of Contents for firewall.

  Duplicate IP address – This condition is rare; however, if you are still able to ping the IP address with the printer powered off, then another device on your network has an identical IP address.

  No, you cannot ping the IP address…

  Possibilities may include the following:

  The printer is on a different network from the computer.

  Action! See “No, you cannot ping the printer’s network gateway address” below.

  MAC filtering or other router setting is preventing success.

  Action! Consult with router manufacturer.

  Interference or over saturation of wireless signals on a wireless local area network.


  Adjust the router’s access point radio channel; e.g., 1 instead of 6.

  Look into bandwidth throttling, or other settings available to maximize signal. Important! Remember that certain router speed boost proprietary modes may not be compatible with the printer’s wireless adapter.

  Consult with router manufacturer.

  Relocate printer, router, or other obstructions, which may be a source of interference or signal loss.

  Timeout condition due to marginally acceptable wireless signal.

  Action! Relocate printer or adjust antenna position(s) on router or printer, if available.

  Click here for an article which describes other communication failures despite a green Wi-Fi indicator light.

  No, you cannot ping the printer’s network gateway address…

  Ask these questions:

  Is the computer connected to the router with a wired connection?

  Is the computer connected to the router with using a wirelessconnection?

  If wired, does any other wireless device communicate with the router? Action: If no, your printer may be connected to a different network. Try to run the Wireless Setup Utility.

  Note: This is found under Lexmark Printer Home for 2009 products and is called Wireless Setup Assistant on a Macintosh computer.

  Is the printer’s IP gateway address the same as the router’s IP address? It should be the same in most situations.

  Explanation example: A printer’s gateway address of should be equal to the same gateway address found under the computer’s ipconfig test. Moreover, this same address provides access to the router’s web page.

  Think of it this way, printer IP gateway address = computer IP gateway address = router IP address.

  Table Key

  AP – In most cases, the access point (AP) refers to the wireless (radio) portion of your router.

   – Lost AP-to-printer radio communication due to router security settings, interference, distance, or placement

  Post – This light-off condition refers to the printer or All-In-one (AIO) going to a Ready state. Therefore, the printer’s wireless adapter is not yet Ready.

  Configured/Connected – Proper network and security type was selected and proper security encryption key or password was properly entered to allow the printer to join the network.

  Network dropped – Lost signal or communication with wireless router or access point (AP)

  Ad-hoc – Refers to a wireless environment in which there is no AP. This would also be called a direct wireless computer-to-printer connection.

  Remember, in order to successfully connect:

  Proper network name (SSID)

  Proper security type (WEP, WPA [TKIP]), or WPA2 (TKIP or AES)), and

  Proper security key or passphrase must all be accurately selected or entered via the Wireless Setup Utility (WSU).

  NOTE: The WSU equivalent in Macintosh environments is called the Wireless Setup Assistant (WSA). This Macintosh assistant can run from the installation CD.

  Wi-Fi protected setup suggestions

  If experiencing problems connecting or joining the network, try the following:




  After the router resets, press and hold down the WPS button on the router again.

  Important! Hold down the button for at least five to ten seconds, or as instructed by the router’s User’s Guide or quick setup guide.


  Allow no more than 50 seconds to reach the printer and then press Connect or OK.

  Why? Two minutes are allowed; however, this is the total time for all required configuration tasks to take place.


  Try initiating the WPS (PBC) method from the printer’s Network Setup > Wireless Networking > Wi-Fi Protected Setup menu instead of the router or printer software.


  Try the WPS personal identification number (PIN) method if the push button control is not working.


  Make sure that Auto Detect is enabled. This setting, present on certain models, is found under Network Setup > Wireless Networking > Wi-Fi Protected Setup.


  Connect the USB cable and run the Wireless Setup Utility.

  Note: This is found under Lexmark Printer Home for printers introduced in 2009. You will need the name of your network name (SSID) and security parameters.

  Hint! Reference the router’s configuration web page to determine the security type (WEP,WPA(TKIP), WPA2(TKIP & AES)), and affiliated key or passphrase.
