Configuring the Linksys LAPAC1750PRO Access Point as 802.1X Supplicant

The 802.1X Supplicant settings allow the access point to gain access to a secured wired network.  You can use these settings to enable the access point as an 802.1X supplicant (client) on the wired network.  An MD5 username and password can be configured to allow the access point to authenticate via 802.1X.
On networks that use IEEE 802.1X, port-based network access control, a supplicant cannot gain access to the network until the 802.1X authenticator grants access.  If your network uses 802.1X, you must configure 802.1X authentication information that the access point can supply to the authenticator.
Step 1:
Access the LAPAC1750PRO access point’s web-based setup page.  For instructions, click here.
Step 2:
Click Configuration > Security > 802.1X Supplicant tab.
Step 3:
Click Enabled to enable the Administrative status of the 802.1X Supplicant.
Step 4:
Select the algorithm to be used for encrypting authentication user names and passwords.  The options are as follows:
  • MD5 — A hash function defined in RFC 3748 that provides basic security.
  • PEAPProtected Extensible Authentication Protocol provides a higher level of security than MD5 by encapsulating it within a TLS tunnel.
  • TLSTransport Layer Security, as defined in RFC 5216, is an open standard that provides a high level of security.
Step 5:
Enter the MD5 Username and Password that the access point will use when responding to requests from an 802.1X authenticator.
NOTE:  The username and password can be up to 64 characters each.  ASCII printable characters are allowed which include upper and lower case alphabet letters, numeric digits, and special symbols such as @ and #.
Step 6:
Select the method to use when uploading a certificate file to the access point, which is either HTTP/HTTPS (upload by web browser) or TFTP (upload by TFTP server).
Step 7:
Specify the path and filename of the certificate file:
  • For HTTP uploads, click Browse to find the location where the certificate file is stored.  Select the file to upload to the access point.  Click Upload to initiate the file transfer.
  • For TFTP uploads, enter the filename, including the path of the certificate.
NOTE:  The Server IP can be the IPv4 or IPv6 address of the TFTP server where the file is located.  The default value is  After you specify the filename and server IP, click Upload to initiate the file transfer.
Step 8:
After you configure the settings on the 802.1X Supplicant page, click  to apply the changes.  
IMPORTANT:  Changing some settings might cause the access point to stop and restart system processes.  If this happens, wireless clients will temporarily lose connectivity.  It is recommended that you change your access point settings when WLAN traffic is low.
