Physical Details
There is one LED.
LED behavior
LED Color Activity Status
Green Blinking System is booting.
Solid System is normal; no wireless devices connected.
Blue Blinking Software upgrade in process.
Solid
System is normal; at least one wireless device connected.
Red Solid Booting process or update failed; hard reset or service
required.
Ports and Button
Power Port—Connect the AC power adapter to this port.
Note—Use only the adapter that came with your access point.
4

Ethernet Port—Connect a wired network device to this port. This port supports PoE (Power over
Ethernet) with a PoE switch or PoE injector. LAPAC1750 can be powered on from an 802.3at
(PoE+) compliance source. Using CAT5e or better cable is highly recommended.
Note—When both PoE and AC power adapter are connected to access point, device will get
power from PoE as higher precedence.
Reset Button—Press and hold this button for less than 15 seconds to power cycle device. Press
and hold for longer than 15 seconds to reset the device to factory default settings.
Mounting Guide
To avoid overheating, do not install your access point if ambient temperatures exceed 104°F
(40°C). Install on a flat, stable surface, near the center of your wireless coverage area making
sure not to block vents on the sides of the device enclosure.
Wall Installation
1. Position drilling layout template at the desired location.
2. Drill four screw holes on the mounting surface. If your Ethernet cable is routed behind the
wall, mark Ethernet cable hole as well.
3. Secure the mounting bracket on the wall with anchors and screws.
4. If your Ethernet cable is routed behind the wall, cut or drill the Ethernet cable hole you
marked in Step 2. Feed the Ethernet cable through the hole.
5. Connect the Ethernet cable and/or AC power adapter to your device.
6. Slide the device into the bracket. Turn clockwise until it locks into place.
Ceiling Installation
1. Select ceiling tile for mounting and remove tile.
2. Position drilling layout template at the desired location.
3. Drill four screw holes and Ethernet cable hole on the surface of ceiling tile.
4. Place back plate on the opposite side of ceiling tile. Secure mounting bracket to the ceiling
tile with flathead screw and nut. Route the Ethernet cable through the Ethernet cable
hole.
5

5. Replace tile in ceiling.
6. Connect the Ethernet cable and/or AC power adapter to your device
7. Slide the device into the bracket. Turn access point clockwise until it locks.
IMPORTANT—Improper or insecure mounting could result in damage to the device or personal
injury. Linksys is not responsible for damages caused by improper mounting.

Chapter 2 - -- Quick Start
Overview
This chapter describes the setup procedure to connect the wireless access point to your LAN, and
configure it as an access point for your wireless stations.
Wireless stations may also require configuration. For details, see Appendix C - Wireless Station
Configuration (p. 104).
The wireless access point can be configured using a web browser.
Setup using a web browser
Your browser must support JavaScript. The configuration program has been tested on the
following browsers:
•Firefox 3.5 or later, Chrome 8 or later, Safari 5 or later
•Internet Explorer 8 or later
Setup Procedure
Make sure device is powered on before you continue setup. If LED light is off, check that AC
power adapter, or PoE cable, is properly connected on both ends.
Access device’s browser-based setup:
1. Use the included cable to connect the access point to your network via a network switch
or router.
2. Open a web browser on a computer connected to your network. Enter the IP address of
your access point. By factory default, the IP address will be assigned by a DHCP server
(usually the network router). If there is no DHCP server on your network, the default IP
address is 192.168.1.252/255.255.255.0.
Note—Use a computer hardwired to the same network as your access point for browser-based
setup access. Access to browser-based setup via Wi-Fi is disabled by default.
3. Type in default username: “admin”, and password: “admin”.
4. Click Log in to launch the browser-based setup and follow the on-screen instructions.
7

If you can't connect:
It is likely that your PC’s IP address is incompatible with the wireless access point’s IP address.
This can happen if your LAN does not have a DHCP Server. If there is no DHCP server in your
network, the access point will fall back to its default IP address: 192.168.1.252, with a network
mask of 255.255.255.0.
Or, if your PC’s IP address is not compatible with this, you must change your PC’s IP address to an
unused value in the range 192.168.1.1 ~ 192.168.1.254, with a network mask of
255.255.255.0. See Appendix A - Windows TCP/IP (p. 98) for details for this procedure.
Setup Wizard
If you are setting up the access point as a standalone device, run the Setup Wizard. If the access
point will be part of a cluster – master or slave - go to Configuration > Cluster > Settings & Status
page instead.
1. Click the Quick Start tab on the main menu.
8

2. On the first screen, click Launch...
3. Set the password on the Device Password screen, if desired.
4. Configure the time zone, date and time for the device on System Settings screen.
5. On the IPv4 Address screen configure the IP address of the device (
Static or Automatic )
then click Next.
9

6. Set the SSID information on the Wireless Network screen. Click Next. If you want to
configure more than four SSIDs, go to Configuration > Wireless > Basic Settings. The
access point supports up to eight SSIDs per radio.
7. On the Wireless Security Screen, configure the wireless security settings for the device.
Click Next. If you are looking for security options that are not available in the wizard, go to
Configuration > Wireless Security page. The access point supports more sophisticated
security options there.
10

8. On the Summary screen, check the data to make sure they are correct and then click
Submit to save the changes.
9. Click Finish to leave the wizard.
