TROUBLESHOOTING
5.1 Unable to Connect or Establish a Session with Unit
If you see the screen as in Figure 5.1 while trying to establish a session with
WiJET.Video, the possible causes are listed below.
Figure 5.1: Target Not Found
1) The SSID of the PC wireless adapter is not set up to be the same as the
unit.
2) The computer’s Wi-Fi Adapter is not set to Infrastructure mode.
3) The computer’s Wi-Fi Adapter is not set to use the same encryption
settings as WiJET.Video once the unit’s default encryption settings were
changed.
4) The unit is somehow not receiving the wireless signal, power-cycle the
WiJET.Video.
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.Video 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.Video and the
computer to take longer. Simply click “Retry” as you see on Figure 27
and let the Connect Status screen show up again. If the “Target Not
Found” window appears again, there probably is no link established
between the WiJET.Video and the computer.
5.2 The Presentation screen appears frozen during a presentation
This indicates that WiJET.Video unit has detected a link-loss. WiJET.Video and 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, The 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.
