Chapter 6 Troubleshooting

This chapter provides solutions to problems usually encountered during the installation and operation of the WAP-4000.

The WAP-4000 cannot power up.

Use an electrical test meter to determine the output voltage of the power supply. Check if it matched the specification of WAP-4000.

Cannot communicate with WAP-4000 through a wired LAN computer.

Check the following:

wWAP-4000 is properly installed, LAN connections are OK, and it is powered ON.

wEnsure that your PC and WAP-4000 are on the same network segment.

wIf your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it.

wIf your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.1.2 to 192.168.1.254 and thus compatible with WAP-4000's default IP Address of 192.168.1.1.

Also, the Network Mask should be set to 255.255.255.0 to match WAP-4000.

In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol.

My wireless client cannot associate with WAP-4000.

Check the following:

wMake sure the wireless adapter is compatible with IEEE 802.11b or 802.11g.

wMove the wireless client closer to WAP-4000.

wEnsure WAP-4000 and the wireless client have the same SSID.

wEnsure WAP-4000 and the wireless client have the same WEP encryption settings, if enabled.

wConfirm the WLAN LED of WAP-4000 is on.

wIf the MAC filter is enabled, please make sure the wireless client is allowed to build the link.

wEnsure the operating mode is in “AP” mode.

The throughput rate is slow.

Check the following:

wVerify the antenna, connector, and cabling are well connected.

wAdjust the antenna, and make sure the antenna is not behind metal or any obstacle. If the throughput increases after you move the client closer to WAP-4000, please consider to add additional WAP-4000 and implement roaming.

wVerify the network traffic does not exceed 37% of bandwidth.

wLower the broadcast rate of wired network to no more than 10 broadcast messages per second

wVerify wired network topology and configuration.
