3. Fill in the fields in the last wizard configuration screen.
Select Get automatically from DHCP to
have the ZyAIR obtain an IP address
from a DHCP server.
You must know the IP address assigned
to the ZyAIR (by the DHCP server) to
access the ZyAIR again.

to access the web configurator again.
4. Change the wireless parameter settings in the wireless stations to match those of the ZyAIR. Refer
to the user’s guide for your wireless adapter.
5 Hardware Mounting Installation
In general, the best location for the access point is at the center of your intended wireless coverage area. For
better performance, mount the ZyAIR high up free of obstructions.
Free-standing
Place your ZyAIR on a flat, level surface (on a desk or shelf) that is strong enough to support the weight of
the ZyAIR with connection cables.
Wall-mounted
Follow the steps to attach your ZyAIR to a wall.
1. Locate a high position on the wall that is free of obstructions.
2. Connect two screws (not included) in the wall 75mm apart. Use screws with 6mm ~ 8mm (0.24" ~
0.31") wide heads. Do not screw the screws all the way in to the wall. Leave a small gap between
the head of the screw and the wall. The gap must be big enough for the screw heads to slide into
the screw slots and the connection cables to run down the back of the ZyAIR.
Make sure the screws are securely fixed to the wall and strong enough to hold
the weight of the ZyAIR with the connection cables.

3. Adjust the cables.
a. Run the connection cables down the back of the ZyAIR.
OR:
b. Run the connection cables upward and along the edge of the ceiling.
4. Align the holes on the back of the ZyAIR with the screws on the wall. Hang the ZyAIR on the
screws.
6 Troubleshooting
PROBLEM CORRECTIVE ACTION
The PWR/SYS
LED is off.
Make sure you are using the correct power adaptor and the power adaptor is
plugged into an appropriate power supply.
Unplug the power adaptor and plug it in again. If the error persists, you may have a
hardware problem. In this case, you should contact your vendor.
The ETHN LED is
off.
Check the cable connection to the ZyAIR ETHERNET port.
Make sure your computer’s network card is working properly.
I cannot access
the web
configurator.
Make sure the IP addresses and subnet masks of the ZyAIR and the computer are
in the same IP address range. (For example, if the ZyAIR is using the default IP
address and subnet mask, check that the IP address of the computer is in the range
192.168.1.3 ~192.168.1.254 and the subnet mask is 255.255.255.0). Refer to the
Setting Up Your Computer’s IP Address section.
If you change the ZyAIR default IP address, then enter the new IP address as the
web site address.
The default password is “1234”. If you have changed the password and have now
forgotten it, you will need to reset the ZyAIR. Refer to the User’s Guide for how to
use the RESET button.
I cannot ping any
computer on the
wireless LAN.
If the ETHN LED is off, check the cables between the ZyAIR and your computer or
hub.
Verify that the IP address and the subnet mask of the ZyAIR and the computers are
in the same range.
