TROUBLESHOOTING 
 
5.1  Unable to Connect or Establish a Session with WiJET-G 
If you see the screen as in Figure 5.1 while trying to establish a session with WiJET-
G(s), the possible causes are listed below.   
 
 
Figure 5.1: Target Not Found 
 
 
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 Ad-Hoc or Peer-to-Peer 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 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-G and the computer. 
 
5.2  The 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
