• Open a command prompt window and type the Ping command along with the IP
address of the device.
For example, ping 10.0.0.1. If the device does not respond, check if you have the
correct IP address. If the device responds then it means the ethernet connection is
working properly.
• Double-check the physical network connections. Use a well-known device to ensure
the network connection is functioning properly.
• Ensure that you are using Microsoft Internet Explorer 7.0 (or later) or Mozilla Firefox
3.0 (or later).
• Ensure that you are not using a proxy server for the network connection with your
Web browser.
• Use CLI, to check the IP Access Table which can restrict access to Telnet and HTTP.
• Ensure that you have not exceeded the maximum number CLI sessions.
• Troubleshoot the network infrastructure (check switches, routers, and so on).
• Also, ensure that the Management VLAN ID is enabled. Refer Virtual Local Area
Network (VLAN)
: At any point of time, if your device is unable to connect to your network, reset the
device by unplugging and plugging the cables from the PoE (if using a PoE).
Connection to the
host is lost
When you try to access the AP Device through HTTP interface (169.254.128.132) during its
initialization, you might receive an error saying “Could not open connection to the host, on
port 23: Connect failed”
Hence, it is recommended to wait for two minutes, until the device is completely initialized
and then try to access the device through HTTP interface.
