6.2 Accessing the ZyXEL Utility
I cannot access the ZyXEL Utility
1 Make sure the NWD2705 is properly inserted and the LEDs are on. Refer to the Quick Start Guide
for information on how to properly connect the NWD2705.
2 Use the Device Manager to check for possible hardware conflicts. Click Start > Settings >
Control Panel > System > Hardware > Device Manager. Verify the status of the NWD2705
under Network Adapter (steps may vary depending on the version of Windows).
3 Install the NWD2705 on another computer.
4 If the error persists, you may have a hardware problem. In this case, you should contact your
vendor.
6.3 Link Quality
The link quality and/or signal strength is poor.
1 Scan for and connect to another AP with a better link quality using the Site Survey screen.
2 Move your computer closer to the AP or the peer computer(s) within the transmission range.
3 There may be too much radio interference (for example from a microwave oven, or another AP
using the same channel) around your wireless network. Lower the output power of each AP.
4 Make sure there are not too many wireless stations connected to a wireless network.
6.4 Problems Communicating with Other Computers
The computer with the NWD2705 installed cannot communicate with the other computer(s).
In Infrastructure Mode
• Make sure that the AP and the associated computers are turned on and working properly.
• Make sure the NWD2705 computer and the associated AP use the same SSID.
• Change the AP and the associated wireless clients to use another radio channel if interference is
high.
