Telnet CLI Does Not Work
1. Make sure you have the proper IP Address. Enter your AP IP address in the Telnet connection dialog, from a DOS
prompt, type:
C:\> telnet <AP IP Address>
2. Use the CLI over the serial port to check the IP Access Table, which can be restricting access to Telnet and HTTP.
TFTP Server Does Not Work
1. Make sure the TFTP Server has been started.
2. Verify the IP address of the TFTP Server. The server may be local or remote, so long as it has a valid IP address.
3. Configure the TFTP Server to “point” to the folder containing the file to be downloaded (or to the folder in which the file
is to be uploaded).
4. Verify that you have entered the proper AP Image file name (including the file extension) and directory path (if
needed).
5. If you have a problem uploading a file, verify that the TFTP server is configured to allow uploads (typically the default
setting is to allow only downloads).
Client Connection Problems
Client Software Finds No Connection
Make sure you have configured your client software with the proper Network Name and Security settings. Network
Names and WEP Keys are typically allocated and maintained by your network administrator.
Client PC Card Does Not Work
1. Make sure you are using the latest PC Card driver software.
2. Download and install the latest ORiNOCO client software from http://support.proxim.com.
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. If using PoE, 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 Mesh and Access Point Module supports 16 VLAN/SSID pairs per wireless interface, each with a configured
security profile.
