Connection Problems; Ping To Test Lan Connectivity - D-Link DWC-1000 User Manual

Section 10 - Troubleshooting
When an access point is converted from standalone mode to managed mode, its static IP address changes to an
IP address that is issued by the DHCP server, either one in the network or one that is configured on the wireless
controller. This occurs to ensure that each managed access point has a unique IP address.
If there is no DHCP server or if the access point cannot reach the DHCP server, the access point remains in the
Connecting state as it tries to obtain an IP address. If there is no DHCP server in the network, configure one on the
wireless controller (see "Step #1: Enable DHCP Server (Optional)" on page 28). When a DHCP server becomes
available, the access point can transition from the Connecting state to the Connected state.
If you added a new SSID, but the SSID does not appear under Wi-Fi Networks within 5 minutes, use the following
procedure to reboot the Wireless Controller.
1. Click Maintenance > Firmware > Soft Reboot.
2. Click Soft Reboot.
Most TCP/IP terminal devices and firewalls contain a ping utility that sends an ICMP echo-request packet to the
designated device. The DWC responds with an echo reply. Troubleshooting a TCP/IP network is made very easy
by using the ping utility in your PC or workstation.
Procedure to test the LAN path from your PC to your controller:
• On the PC's Windows toolbar, Click Start, and click Run.
• Type ping <IP_address> where <IP_address> is the controller's IP address. Example: ping 192.168.10.1.
• Click OK.
• Observe the display:
• If the path is working, you see the following message sequence:
Pinging <IP address> with 32 bytes of data
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
• If the path is not working, you see the message sequence given below:
Pinging <IP address> with 32 bytes of data
Request timed out.
• If the path is not working, test the physical connections between PC and controller.
• If the LAN port LED is off, go to the "LED displays" section and follow instructions for "LAN or Internet port
LEDs are not lit. "
• Verify that the corresponding link LEDs are lit for your network interface card and for any hub ports that
are connected to your workstation and firewall.
• If the path is still not up, test the network configuration:
• Verify that the Ethernet card driver software and TCP/IP software are installed and configured on the PC.
• Verify that the IP address for the controller and PC are correct and on the same subnet.
