1 Make sure the NWD-270N is properly inserted and the LEDs are on. Refer to the Quick 

Start Guide for information on how to properly connect the NWD-270N.

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 NWD-270N under Network Adapter (steps may vary depending on the version 
of Windows). 

3 Install the NWD-270N on another computer.
4 If the error persists, you may have a hardware problem. In this case, you should contact 

your vendor.

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.

The computer with the NWD-270N 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 NWD-270N computer and the associated AP use the same SSID.
