Troubleshooting the AP-700 AP-700 User Guide
Symptoms and Solutions
125
Intermittent Loss of Connection
1. Make sure you are within range of an active AP.
2. You can check the signal strength using the signal strength gauge on your client software.
Client Does Not Receive an IP Address - Cannot Connect to Internet
1. If the AP is configured as a DHCP server, open the Web-browser Interface and select the Configure button and then the Network tab to
make sure the proper DHCP settings are being used.
2. If you are not using the DHCP server feature on the AP, then make sure that your local DHCP server is accessible from the Access Point’s
subnet.
3. From the client computer, use the “ping” network command to test the connection with the AP. If the AP responds, but you still cannot
connect to the Internet, there may be a physical network configuration problem (contact your network support staff).
4. If using Active Ethernet, make sure you are not using a crossover Ethernet cable between the AP and the hub.
VLAN Operation Issues
Verifying Proper Operation of the VLAN Feature
The correct VLAN configuration can be verified by “pinging” both wired and wireless hosts from both sides of the AP device and the network
switch. Traffic can be “sniffed” on both the wired (Ethernet) and wireless (WDS) backbones (if configured). Bridge frames generated by
wireless clients and viewed on one of the backbones should contain IEEE 802.1Q compliant VLAN headers or tags. The VLAN ID in the
headers should correspond to one of the VLAN User IDs configured for the AP.
NOTE
The AP-700 supports 16 VLAN/SSID pairs, each with a configured security profile.
VLAN Workgroups
The correct VLAN assignment can be verified by pinging the AP to ensure connectivity, by pinging the switch to ensure VLAN properties, and
by pinging hosts past the switch to confirm the switch is functional. Ultimately, traffic can be “sniffed” on the Ethernet or WDS interfaces (if
configured) using third-party packages. Most problems can be avoided by ensuring that 802.1Q compliant VLAN tags containing the proper
VLAN ID have been inserted in the bridged frames. The VLAN ID in the header should correspond to the user’s assigned network name.
What if network traffic is being directed to a nonexistent host?
• All sessions are disconnected, traffic is lost, and a manual override is necessary
• Workaround: you can configure the switch to mimic the nonexistent host
