ZyAIR G-3000 Quick Start Guide
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 should
contact your vendor.
If the LED is off then maybe the ZyAIR is set up to communicate in Access Point
mode and is not in AP+Bridge mode or Bridge/Repeater mode.
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.
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.
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.
Check the wired connection between the ZyAIR ETHERNET port and your computer
or hub.
Make sure your computer's network card is working properly.
