Section 1: Getting Started
The LAPAC1750PRO Access Point provides continuous, high-speed access
between wireless devices and Ethernet devices. It is an advanced, standards-
based solution for wireless networking in businesses of any size. The access point
(AP) enables wireless local area network (WLAN) deployment while providing
state-of-the-art wireless networking features.
The access point works in Standalone Mode, which means it is an individual
access point in your network. You manage the device through a Web-based user
interface (UI) or SNMP (Simple Network Management Protocol.
This document describes how to perform the setup, management, and
maintenance of the access point in Standalone Mode.
Before you power on a new access point, review the following sections to
check required hardware and software components, client configurations, and
compatibility issues. Make sure you have everything you need for a successful
launch and test of your new or extended wireless network.
This section contains the following topics:
• Administrator’s Computer Requirements
• Wireless Client Requirements
• Online Help, Supported Browsers, and Limitations
• Dynamic and Static IP Addressing
• Installing the Access Point
• Configuring the Ethernet Settings
• Configuring IEEE 802.1X Authentication
• Configuring Security on the Access Point
To manage the access point by using the Web interface, the AP needs an IP
address. If you use VLANs or IEEE 802.1X Authentication (port security) on your
network, you might need to configure additional settings on the AP before it can
connect to the network.
NOTE:
The access point is not designed to function as a gateway to the Internet.
To connect your WLAN to other LANs or the Internet, you need a gateway
device.
Administrator’s Computer Requirements
The following table describes the minimum requirements for the administrator’s
computer for configuration and administration of the access point through a
Web-based user interface (UI).
Table 1: Requirements for the Administrator’s Computer
Required Software or
Component
Description
Ethernet Connection to
the Access Point
The computer used to configure the first access
point must be connected to the access point by
an Ethernet cable.
Wireless Connection to
the Network
After initial configuration and launch of the first
access point on your new wireless network, you
can make subsequent configuration changes
through the Administration Web pages using a
wireless connection to the internal network. For
wireless connection to the access point, your
administration device will need Wi-Fi capability
similar to that of any wireless client: a portable
or built-in Wi-Fi client adapter that supports one
or more of the IEEE 802.11 modes in which you
plan to run the access point.

Section 1: Getting Started
LAPAC1750PRO Access Point Software User Manual
Web Browser and
Operating System
Configuration and administration of the
access point is provided through a Web-based
user interface hosted on the access point.
We recommend using one of the following
supported Web browsers to access the access
point Administration Web pages:
• Microsoft® Internet Explorer® version 9.x or
11.x (with up-to-date patch level for either major
version)
• Mozilla Firefox version 26.x
• Google Chrome version 32.x
• Safari version 5.x
The administration Web browser must have
JavaScript™ enabled to support the interactive
features of the administration interface.
Security Settings Ensure that security is disabled on the wireless
client used to initially configure the access point.
Wireless Client Requirements
The access point provides wireless access to any client with a properly configured
Wi-Fi client adapter for the 802.11 mode in which the access point is running. The
access point supports multiple client operating systems. Clients can be laptop
or desktop computers, personal digital assistants (PDAs), or any other handheld,
portable or stationary device equipped with a Wi-Fi adapter and supporting
drivers.
In order to connect to the access point, wireless clients need the software and
hardware described in the following table.
Table 2: Requirements for Wireless Clients
Required Component Description
Wi-Fi Client Adapter Portable or built-in Wi-Fi client adapter that
supports one or more of the IEEE 802.11 modes
in which you plan to run the access point. (IEEE
802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac
modes are supported.)
Wireless Client
Software
Client software, such as Microsoft Windows
Supplicant, configured to associate with the access
point.
Client Security
Settings
Security should be disabled on the client used to
do initial configuration of the access point.
If the Security Mode on the access point is set to
anything other than plain text, wireless clients
will need to set a profile to the authentication
mode used by the access point and provide a valid
username and password, certificate, or similar user
identity proof. Security modes are Static WEP, IEEE
802.1X, WPA with RADIUS server, and WPA-PSK.
For information about configuring security on the
access point, see ”Virtual Access Point (VAP).”
Online Help, Supported Browsers, and
Limitations

LAPAC1750PRO Access Point Software User Manual
Figure 1: Administrator UI Online Help
Dynamic and Static IP Addressing on the AP
When you power on the access point, the built-in DHCP client searches for a
DHCP server on the network in order to obtain an IP address and other network
information. If the AP does not find a DHCP server on the network, the AP
continues to use its default Static IP Address (192.168.1.252) until you reassign it
a new static IP address (and specify a static IP addressing policy) or until the AP
successfully receives network information from a DHCP server.
To change the connection type and assign a static IP address by using the Web
UI, see “VLAN and IPv4 Address” on page 29.
NOTE:
If you do not have a DHCP server on your internal network, and do
not plan to use one, the first thing you must do after powering on the
access point is change the connection type from DHCP to static IP. You
can either assign a new static IP address to the AP or continue using the
default address. We recommend assigning a new static IP address so that
if you bring up another WLAN AP on the same network, the IP address for
each AP will be unique.
Recovering an IP Address
If you experience trouble communicating with the access point, you can recover
a static IP address by resetting the AP configuration to the factory defaults (see
“Restoring Configuration” on page 114 and “To Restore the Factory Default
Configuration” on page 114), or you can get a dynamically assigned address by
connecting the AP to a network that has a DHCP server.
Discovering a Dynamically Assigned IP
Address
If you have access to the DHCP server on your network and know the MAC
address of your AP, you can view the new IP address associated with the MAC
address of the AP.
NOTE:
The MAC address of access point is shown on product label and brown
box label.
Installing the Access Point
To access the Administration Web UI, you enter the IP address of the AP into a
Web browser. You can use the default IP address of the AP (192.168.1.252) to log
on to the AP and assign a static IP address, or you can use a DHCP server on you
network to assign network information to the AP. The DHCP client on the AP is
enabled by default.
To install the access point, use the following steps:
1. Connect the AP to an administrative PC by using a LAN connection or a
direct-cable connection.

4
Section 1: Getting Started
LAPAC1750PRO Access Point Software User Manual
•To use a LAN connection, connect one end of an Ethernet cable to the
network port on the access point and the other end to the same hub where
your PC is connected, as shown in the following figure.
The hub or switch you use must permit broadcast signals from the access point
to reach all other devices on the network.
•To use a direct-cable connection, connect one 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 PC, as shown in the
following figure. You can also use a serial cable to connect the serial port
on the AP to a serial port on the administrative computer.
For initial configuration with a direct Ethernet connection and no DHCP server,
be sure to set your PC to a static IP address in the same subnet as the default
IP address on the access point. (The default IP address for the access point is
192.168.1.252.)
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 PC 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, we strongly advise against using this method.
In most environments you may have no way of knowing whether you
are actually connecting to the intended AP. Also, many of the initial
configuration changes required will cause you to lose connectivity with
the AP over a wireless connection.
NOTE:
Ethernet Port 1 and Port 2 can be used together in Link Aggregation
Mode when supported by the connected devices.
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.
3. Use your Web browser to log on to the access point Administration Web
pages.
•If the AP did not acquire an IP address from a DHCP server on your network,
enter 192.168.1.252 , the default IP address of the AP, in the address field of
your browser.
•If you used a DHCP server on your network to automatically configure
network information for the AP, enter the new IP address of the AP into the
Web browser.
4. When prompted, enter admin for the user name and admin for the
password, then click Log In.
•When you first log in, the System Summary page for access point
administration is displayed, as the following figure shows.

5
Section 1: Getting Started
LAPAC1750PRO Access Point Software User Manual
Figure 2: System Summary Page
5. Verify the settings on the System Summary page.
•Review access point description.
For information about the fields on the System Summary page, see “System
Summary” on page 7.
6. 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 AP or continue using
the default address. We recommend assigning a new Static IP address
so that if you bring up another access point on the same network, the IP
address for each AP will be unique. To change the connection type and
assign a static IP address, see“VLAN and IPv4 Address”on page 29.
7. 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 information, see“VLAN
and IPv4 Address” on page 29.
8. If your network uses IEEE 802.1X port security for network access control,
you must configure the 802.1X supplicant information on the AP.
For information about how to configure the 802.1X user name and
password, see “802.1X Supplicant” on page 65.
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 interface to configure the Ethernet
settings, see “VLAN and IPv4 Address” on page 29.

Section 1: Getting Started
LAPAC1750PRO Access Point Software User Manual
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 AP can supply to the authenticator.
If your network uses IEEE 802.1X see “802.1X Supplicant” on page 65 for
information about how to configure 802.1X by using the Web interface.
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 AP by modifying
advanced configuration features.
1. Connect the access point to the LAN.
•If you configured the access point and administrator PC by connecting
both into a network hub, 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:
a. Disconnect the cable from the computer and the access point.
b. Connect an Ethernet cable from the access point to the LAN.
c. Connect your computer to the LAN by using an Ethernet cable or a
wireless card.
2. Test LAN connectivity with wireless clients.
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, see“Wireless Client Requirements” on page 2.
3. Secure and configure the access point by using advanced features.
Once the wireless network is up and you can connect to the AP 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 administrator is logged onto the
Administration Web pages and making changes to the configuration,
there is no guarantee that all configuration changes specified by multiple
users will be applied.
By default, no security is in place on the access point, so any wireless client
can associate with it and access your LAN. An important next step is to
configure security, as described in “Virtual Access Point (VAP)”on page 43.
Configuring Security on the Wireless
Access Point
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 APs in one physical access point. By default, only
one 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. VAP0 has the following default settings:
•VLAN ID: 1
•Broadcast SSID: Enabled
•SSID: LinksysSMB24G for Radio 1 (2.4GHz), and LinksysSMB5G for Radio 2
(5GHz)
•Security: None
•MAC Authentication Type: None
•Redirect Mode: 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, we recommend that you
select and configure a security option other than None for the default VAP and
for each VAP that you enable.
For information about how to configure the security settings on each VAP, see
“Virtual Access Point (VAP)” on page 43.

Section 2: Viewing Access Point System Status

Status The Authenticated and Associated Status shows the
underlying IEEE 802.11 authentication and association
status, which is present no matter which type of security
the client uses to connect to the AP. This status does not
show other (IEEE 802.1X) authentication or association
status.
Some points to keep in mind with regard to this field are:
•If the AP security mode is None or Static WEP, the
authentication and association status of clients
showing on the Client Associations tab will be in
line with what is expected; that is, if a client shows
as authenticated to the AP, it will be able to transmit
and receive data. (This is because Static WEP uses
only IEEE 802.11 authentication.)
•If the AP uses IEEE 802.1X or WPA security, however,
it is possible for a client association to show on this
tab as authenticated (via the IEEE 802.11 security)
but actually not be authenticated to the AP via the
second layer of security.
From Station
These fields report information about traffic sent from a wireless client to
the AP.
Packets The number of packets received from the wireless client.
Bytes The number of bytes received from the wireless client.
Drop Packets The number of packets that were dropped after being
received.
Drop Bytes The number of bytes that were dropped after being
received.
TS Violate
Packets
The number of packets sent from a wireless client to the
AP in excess of its active TS uplink bandwidth, or for an
access category requiring admission control to which
the wireless client has not been admitted.
To Station
These fields report information about traffic sent from the AP to a wireless
client.
Packets The number of packets sent from the AP to the wireless
client.
Bytes The number of bytes sent from the AP to the wireless
client.
Drop Packets The number of packets that the AP attempted to send to
the wireless client but were dropped.
Drop Bytes The number of bytes that the AP attempted to send to
the wireless client but were dropped.
TS Violate
Packets
The number of packets sent from the AP to a wireless
client in excess of its active TS downlink bandwidth, or
for an access category requiring admission control to
which the wireless client has not been admitted.
Link Integrity Monitoring
The access point provides link integrity monitoring to continually verify its
connection to each associated client. To do this, the AP sends data packets to
clients every few seconds when no other traffic is passing. This allows the AP to
detect when a client goes out of range, even during periods when no normal
traffic is exchanged. The client connection drops off the list within 300 seconds
if these data packets are not acknowledged, even if no disassociation message
is received.

TSPEC Client Associations
The TSPEC Client Association Status and Statistics page provides information
about the TSPEC client data transmitted and received by this access point. Table
10 shows voice and video packets transmitted and received by the association,
along with status information.
The page shows a real-time display of transmit and receive statistics for the
TSPEC clients. All transmit and receive statistics shown are totals since the client
association started.
A TSPEC is a traffic specification that is sent from a QoS-capable wireless client
to an AP requesting a certain amount of network access for the traffic stream
(TS) it represents. A traffic stream is a collection of data packets identified by
the wireless client as belonging to a particular user priority. An example of a
voice traffic stream is a Wi-Fi-certified™ telephone handset that marks its codec-
generated data packets as voice priority traffic. An example of a video traffic
stream is a video player application on a wireless laptop that prioritizes a video
conference feed from a corporate server.
To view TSPEC Client Association statistics, click the System Status > TSPEC Client
Associations tab.
