Make sure you are using the correct power adaptor and the power adaptor is plugged
into an adequate power supply.
Turn the ZyAIR off and on. If the error persists, you may have a hardware problem. In
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 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.
