Solution

Overview 

This article explains how you can avoid having to run the Wireless Configuration Utility or Wireless Setup Assistant (Macintosh) after making changes to the router's security settings. The need to change these settings can arise if users forget their network key/passphrase or router web server password or if you have security concerns.   

Printer response to security settings changes

The printer will respond with a flashing orange () Wi-Fi indicator light after the following actions are performed on the network or router/access point (AP):

  • -A change to the Service Set Identifier (SSID) or network name.

  • -A change to the security type (none, WEP, WPA, or WPA2 personal).

  • -A change to the security network key/passphrase.

  • -A hard reset of the router followed by entry of security values that are different from the original values. 

  • -The printer is moved to a network (AP) that has different security values but already has installed drivers and created ports.  NOTE: Port reconfiguration may be required in this case. Click here for instructions.  

In order to rejoin (associate and authenticate) the wireless network (WLAN), the wireless client (printer) has to be reconfigured with the router's new SSID, security type, and network key. This requires connecting the USB configuration cable to the host computer and running the Wireless Configuration Utility or Wireless Setup Assistant to apply the new security settings on the printer's wireless network adapter.  

Solution:  Change the printer settings first

Change the security settings on the printer while it is still communicating on the network before making the changes on the router. Understand that this will cause a temporary change in the Wi-Fi indicator light from   to .  After you have made equivalent changes on the router, the printer's Wi-Fi indicator light will return to .  

Procedure: How to change security settings via the embedded web server 

If you change your AP security settings frequently, this procedure is for you.  

  1. Open your web browser application and enter the printer IP address into the web address field, i.e. http://ip_address.

  2. Click on Configuration.  

  3. Click on Wireless.  

  4. Enter the SSID, security type/encryption, and network key that will be used to configure the router.   

  5. Click Submit.
