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.  

 

This signals that the WiJET-G has detected a link-loss for an extended period of time or 
severe communication error. Since the WiJET-G is designed to support one 
presentation at a time, the WiJET-G cleans up the communication error and returns 
itself to the initial state (where displaying the banner page is a part) of being “available 
for connection” in order to prevent the WiJET-G from being locked up with one possibly 
malfunctioning user computer.  With the auto-reconnection feature, this rarely occurs. 

 

When this condition occurs, follow the steps below: 

1)  The current presenter should click “Establish a Session” to try to resume the 

presentation. If the presentation is successfully resumed, the abnormal 
condition is just temporary and no further action is required. 

2)  If the current presenter failed to resume presentation by clicking “Establish a 

Session”, another presenter should try to “Establish a Session”. If this new 
presenter can successfully start a presentation, the problem was localized on 
the previous presenter’s computer and/or its wireless card. Address that 
problem after the meeting. 

3)  If a second presenter also fails to “Establish a Session” to the WiJET-G, a 

persistent abnormal condition has to be identified. Follow other trouble-shooting 
tips in this chapter to identify the persistent abnormal condition. 

 

You may be able to eliminate RF interference by trying the following: 

• 

Find the “channel” used by the source of the interference and coordinate your 
network and the interference source to be on channels that are at least 20MHz, 
but preferably 30MHz, apart. 

• 

Reseat the WiJET-G to a location where the interference is minimized; in 
general, increase the distance between the wireless computers and the device 
causing radio interference. 

• 

Avoid using 2.4GHz cordless phone in the vicinity of the radio 

• 

Keep the computer with the WiJET-G away from the microwave oven and large 
metal objects. 

• 

Consult the dealer or an experienced radio technician for help.
