4.3 Accessing the ZyXEL Utility

I cannot access the ZyXEL Utility

1 Make sure the N220 is properly inserted and the LEDs are on.

2 Install the N220 on another computer.

3 If the error persists, you may have a hardware problem. In this case, you should

contact your vendor.

4.4 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.
