Installing the access point
To install the access point, follow these steps:
Step 1:
Connect using a LAN connection or a direct-cable connection.
Option 1
To use a LAN connection, connect an Ethernet cable to either Port 1 or Port 2 of the access point and the other end to the same network where your computer is connected.
QUICK TIP:  If you are using a PoE switch, you must use Port1.  The hub or switch you use must permit broadcast signals from the access point to reach all other devices on the network.

Option 2
To use a direct-cable connection, connect one (1) end of an Ethernet straight-through or crossover cable to the network port on the access point and the other end of the cable to the Ethernet port on the computer.
For initial configuration with a direct Ethernet connection and no DHCP server, be sure to set your computer to a static IP address in the same subnet as the default IP address on the access point. 
NOTE:  The default IP address for the access point is when AP does not detect a DHCP server.
If you use this method, you will need to reconfigure the cabling for subsequent startup and deployment of the access point, so that the access point is no longer connected directly to the computer but instead is connected to the LAN (either by using a hub or directly).
NOTE:  It is possible to detect access points on the network with a wireless connection. However, it is strongly advised not to use this method.  In most environments, you may have no way of knowing whether you are actually connecting to the intended access point.  Also, many of the initial configuration changes required will cause you to lose connectivity with the access point over a wireless connection.
QUICK TIP:  Ethernet Port 1 and Port 2 can be used together in Link Aggregation Mode when supported by the connected devices.
Step 2:
Connect the power adapter to the power port on the back of the access point, and then plug the other end of the power cord into a power outlet.  
NOTE:  If you are using a PoE switch, you won’t need to use Power adapter.
Step 3:
Use your web browser to log in to the access point’s web-based setup page.
NOTE:  By default the AP is a DHCP client, you may need to look up the IP address in your network.  If the AP does not detect a DHCP server, the access point’s default IP address is
Step 4:
When prompted, enter “admin” for the Username and Password then click Log In.
When you first log in, the System Summary page for access point administration is displayed.

Step 5:
Verify the settings on the System Summary page and review access point description.   
  • If you do not have a DHCP server on the management network and do not plan to use one, you must change the Connection Type from DHCP to Static IP.
You can either assign a new Static IP address to the access point or continue using the default address.  It is recommended to assign a new Static IP address so that if you bring up another access point on the same network, the IP address for each access point will be unique.  To know how to change the connection type and assign a static IP address, click here.
  • If your network uses VLANs, you might need to configure the management VLAN ID or untagged VLAN ID on the access point in order for it to work with your network.
For information about how to configure VLAN, click here.
  • If your network uses IEEE 802.1X port security for network access control, you must configure the 802.1X supplicant information on the access point.
For instructions on how to configure the 802.1X username and password, click here.
Configuring the Ethernet settings
The default Ethernet settings, which include DHCP and VLAN information, might not work for all networks.  By default, the DHCP client on the access point automatically broadcasts requests for network information.  If you want to use a static IP address, you must disable the DHCP client and manually configure the IP address and other network information.
The management VLAN is VLAN 1 by default.  This VLAN is also the default untagged VLAN.  If you already have a management VLAN configured on your network with a different VLAN ID, you must change the VLAN ID of the management VLAN on the access point.
For information about using the web-based setup page to configure the Ethernet settings, click here.
Configuring IEEE 802.1X authentication
On networks that use IEEE 802.1X, port-based network access control, a supplicant (client) 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.
For instructions on how to configure the 802.1X username and password, click here.
Verifying the installation
Make sure the access point is connected to the LAN and associate some wireless clients with the network.  Once you have tested the basics of your wireless network, you can enable more security and fine-tune the access point by modifying advanced configuration features.
Step 1:
Connect the access point to the LAN.
  •  If you configured the access point and admin computer by connecting both into a network, then your access point is already connected to the LAN.  The next step is to test some wireless clients.
  • If you configured the access point by using a direct cable connection from your computer to the access point, do the following procedures:
i. Disconnect the cable from the computer and the access point.
ii. Connect an Ethernet cable from the access point to the LAN.
iii. Connect your computer to the LAN by using an Ethernet cable or a wireless card.
Step 2:
Test LAN connectivity with wireless clients.
QUICK TIP:  You can test the access point by trying to detect it and associate with it from some wireless client devices.  For information about requirements for these clients, click here.
Step 3:
Secure and configure the access point by using advanced features.  Once the wireless network is up and you can connect to the access point with some wireless clients, you can add in layers of security, create multiple virtual access points (VAPs), and configure performance settings.
NOTE:  The WLAN AP is not designed for multiple, simultaneous configuration changes.  If more than one (1) administrator is logged onto the web-based setup page and making changes to the configuration, there is no guarantee that all configuration changes specified by multiple users will be applied.
By default, no wireless security is in place on the access point, so any wireless client can associate with it and access your LAN.  To know how to configure the security settings on each VAP, click here.
Configuring security
You configure secure wireless client access by configuring security for each virtual access point (VAP) that you enable.  You can configure up to 8 VAPs per radio that simulate multiple access points in one (1) physical access point.  By default, only one (1) VAP is enabled.  For each VAP, you can configure a unique security mode to control wireless client access.
Each radio has 8 VAPs, with VAP IDs from 0-7.  By default, only VAP 0 on each radio is enabled.  VAP 0 has the following default settings:
  • VLAN ID:  1
  • Broadcast SSID:  Enabled
  • Default SSIDs:  LinksysSMB24G for Radio 1 (2.4GHz), and LinksysSMB5G for Radio 2 (5GHz)
  • Security:  None
  • MAC Authentication Type:  None
All other VAPs are disabled by default.  The default SSID for VAPs 1–7 is Virtual Access Point x where x is the VAP ID.  To prevent unauthorized access to the access point, it is recommended that you select and configure a security option other than None for the default VAP and for each VAP that you enable.
