this case, you should contact your vendor.
Check the cable connection to the ZyAIR LAN port.
Make sure your computer’s network card is working properly.
Turn the ZyAIR off and on. If the error persists, you may have a hardware problem. In
this case, you should contact your vendor.
Make sure that the access point and the associated computers are turned on and
working properly.
Move your computer closer to the access point or the peer computer(s) within the
transmission range.
There is too much radio interference (for example microwave or another access
point) around your wireless network. Relocate or reduce the radio interference.
Optimize the performance of the WLAN by ensuring that the distance between
access points is not too far. In most buildings, most WLAN adapters operate within a
range of 100 ~ 300 feet, depending on the thickness and structure of the walls.
Radio waves can pass through walls and glass but not metal. If there is interference
in transmitting through a wall, it may be that the wall has reinforcing metal in its
structure. Install another access point to circumvent this problem.
Floors usually have metal girders and metal reinforcing struts that interfere with
WLAN transmission.

ZyAIR G-2000 Plus Quick Start Guide
PROBLEM CORRECTIVE ACTION
I cannot access the
web configurator.
I cannot ping any
computer on the
LAN.
I cannot get a WAN
IP address from the
ISP.
I cannot access the
Internet.
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
192.168.1.2 ~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.
If all of the LAN LEDs are 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
on the same IP address range.
The WAN IP is provided after the ISP verifies the MAC address, host name or user
ID.
Find out the verification method used by your ISP and configure the corresponding
fields.
Make sure the ZyAIR is turned on and connected to the network.
Make sure you entered your username correctly. A username may be case-sensitive.
