About Infrastructure Mode

Infrastructure Mode is the most common wireless network environment. This mode offers the fastest wireless data transfers and allows multiple secure wireless connections. Click here for a graphical representation.

Article overview

This article aims to provide you with a basic understanding of the concepts and critical values required for successful installation and setup of the Z4550  in an infrastructure wireless environment.
Common terms and associations:
Wireless Router: Access Point (AP)
SSID (= Service Set Identifier): network name
BSS (= Basic Service Set) Type: ad hoc or infrastructure
Security Type: WEP, WPA, WPA2
Security Key: network key, passphrase, password 
See the Wireless Glossary for an explanation of these terms.

Before you begin

Obtain the settings enumerated in the steps below.
Step 1. Wireless router/access point (AP) settings. 
Click here for instructions on how to access your AP web page to obtain WEP, WPA, or WPA2 settings. NOTE: This document serves as an example only; refer to your router's web page or user's guide for further information.
First make sure that the access point or wireless radio is turned ON or ENABLED. Click here for an illustration.
AP SettingSample Value
SSID (Service Set Identifier).
NOTE:   Every Wi-Fi device has a default SSID value; however, it is highly recommended that you change the default SSID name to a unique value to differentiate your AP from other APs in your area.   
Security Type (Authentication Type)WPA - PSK
NOTE: Knowing the channel can be important, as you will see in step 12a. 

Password, passphrase, security key or network key
Security key rules
WEP security keys

  • •Exactly 10 or 26 hexadecimal characters. (Hexadecimal characters are A–F and 0–9.)

  • • Exactly 5 or 13 ASCII characters. (ASCII characters are letters, numbers, and symbols found on a keyboard.)

WPA-PSK or WPA2-PSK security key

  • • Up to 64 hexadecimal characters. (Hexadecimal characters are A–F and 0–9.)

  • • Between 8 and 64 ASCII characters. (ASCII characters are letters, numbers, and symbols found on a keyboard.) 

IMPORTANT! Security keys are case-sensitive. Improper entry of lower- or upper-case letters will result in configuration failure.

Advanced security features

IMPORTANT! These AP features, if not set correctly, will cause configuration failure:

MAC Filtering - Verify that this is OFF, or create an exception using the printer's UAA (=MAC) address. 
DHCP enable -  Verify that this is ON.
Broadcast SSID - Verify that this is ON.
AP Firewall - Verify that this is OFF.

  • • Refer to your wireless router/access point documentation for further assistance. 

  • • The naming convention of these features may vary. Again, refer to your wireless router/access point documentation.

  • • French Telecom (Darty, Free, Alice, N9UF) box owners: click here for special instructions.

IMPORTANT! Software firewalls are the leading cause of configuration failure and, frequently, communication failure after installation. Select grant always pertaining to permissions or an equivalent message from the software firewall manufacturer. Click here for related articles on firewall issues. 
Step 2. Make sure your host computer is communicating with the network and the router.
Step 3. Print a network settings pageClick here for instructions. 
Although not necessary for first-time setup, if your listed default values are different from those in the table below, you may want to carry out the following checks:

  • • Check the Wi-Fi indicator light. It should be   (orange solid) after Step 6 for first-time setup.

  • • If the software is already installed on the computer and the Wi-Fi indicator is blinking orange, run the Wireless Setup Utility. See 'Related Articles' below. 

  • • If the Wi-Fi indicator light is in another state, click here for an article describing Wi-Fi indicator light possibilities and Printer Status

  • • If a gateway exists, ping the gateway. NOTE: The gateway value is often the IP address of the wireless router or access point. See 'Related Articles'.

  • • Perform an ipconfig  procedure on your host computer to see if the printer and computer netmask and gateway values match. See 'Related Articles'.

  • • (DHCP- Would indicate that the device was previously configured)

  • • (Auto IP- Would indicate that the device attempted to obtain an IP address but the wireless router acting as DHCP server failed to assign or send  the printer an address, leading to a 169.254.#.# address with a netmask.
BSS TypeAd hoc (this will change to Infrastructure by the end of the procedure)
SSID (network name)Print Server 02CD60
UAA - MAC address00200002CD60 (printer-unique)
Notice that the SSID uses the ending values of the MAC address. (The UAA/MAC address is also located on the back of the printer.)
NOTE: This six-digit alphanumeric value becomes part of the port name and helps to identify the correct port to capture should the need arise.
