Chapter 5: TROUBLESHOOTING
5.1Unable to Connect or Establish a Session with WiJET.G
If you could not establish a session with WiJET.G(s) and get a message box indicating no WiJET.G is available for connection or no WiJET.G is found, the possible causes are listed below.
1)The SSID of the wireless adapter is not set up to be the same as the WiJET.G’s.
2)The computer’s Wi-Fi Adapter is not set to Infrastructure Station mode.
3)The computer’s Wi-Fi Adapter is not set to use the same encryption settings as WiJET.G, if WiJET.G’s default encryption settings were changed.
4)The WiJET.G is somehow not receiving the wireless signal, power-cycle the WiJET.G.
5)Some DHCP-enabled wireless network connection client may take a while to obtain a valid OS-assigned IP address. You can use “ipconfig” command to see whether a valid IP address has been assigned or not to the corresponding network connection.
6)With certain brands of PCMCIA 802.11g Wi-Fi cards, it might take a bit longer to link up with the WiJET.G than with other brands of PCMCIA cards. The reason for this is that the drivers and features set of each brand might cause the link up time between the WiJET.G and the computer to take longer. Simply try to establish a session again. If the same issue persists, there probably is no link established between the WiJET.G and the computer.
5.2The Presentation screen appears frozen during a presentation
This indicates that WiJET.G has detected a link-loss. WiJET.G and WiJET.G PSM have an intelligent built-in mechanism to detect the link-loss and can automatically restore the connection by coordination. When a link-loss has been detected, WiJET.G PSM displays a message box and trying to automatically restore the connection. If the auto- reconnection attempt is successful, user does not need to do anything. In this case, the auto-reconnection is user transparent. However, if the cause to the link-loss is due to physical disconnection, for instance, the PCMCIA card was pulled out, user needs to restore the physical connection so that the auto-reconnection attempt can succeed. The presentation screen won’t be updated once the link is lost, unless a reconnection is re-established. However, if link-loss stays for an extended period, the WiJET.G will terminate the reconnection waiting state and display the banner page indicating that a fresh presentation session is ready for being established.
The default duration for a link-loss is 8 seconds. WiJET.G will retry 3 periods of this duration. If no re-connection is established before the reconnection time running out, WiJET.G returns itself to the banner page.
