Search and connect to another AP with a better link quality using the Site Survey screen. Move your computer closer to the AP or the peer computer(s) within the transmission range. There may be too much radio interference (for example microwave or another AP using the same channel) around your wireless network. Lower the output power of each AP. Make sure there are not too many wireless stations connected to a wireless network. 8.4 Problems Communicating With Other Computers Table 21 Troubleshooting the Ethernet Interface PROBLEM The computer with the ZyXEL Device installed cannot communicate with the other computer(s). CORRECTIVE ACTION In Infrastructure Mode • Make sure that the AP and the associated computers are turned on and working properly. • Make sure the ZyXEL Device 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. • Make sure that the computer and the AP share the same security option and key. Verify the settings in the Profile Security Settings screen. • If you are using WPA(2) or WPA(2)-PSK security, try changing your encryption type from TKIP to AES or vice versa. 76 Chapter 8 Troubleshooting
