Access Point then try initiating a search manually if the client software 
supports this feature or manually set the channel on your wireless 
computer to correspond to the Access Point channel number. Please 
refer to your Wireless computer adapter documentation and vendor 
to do this.

Speed of connection: The 802.11b standard will automatically choose 
the best speed depending on the quality of your connection. As the 
signal quality weakens then the speed falls back to a lower speed. The 
speeds are 11Mbps, 5.5Mbps, 2Mbps and 1Mbps. In general the 
closer you are to the Access Point the better the speed. If you are not 
achieving the speed you had anticipated then try moving the antenna 
on the Access Point or moving the Wireless computer closer to the 
Access Point. In an ideal network the Access Point should be located 
in the centre of the network with Wireless computers distributed 
around it. Applications are generally available with the computer 
wireless card to carry out a site survey. Use this application to find the 
optimal siting for your wireless computer. Consult your Wireless Card 
documentation and vendor for more details.

The Alert LED will flash when the Access Point unit is first powered up 
while the system software checks the hardware for proper operation. 
Once the Access Point has started normal operation, the Alert LED will go 
out.

■

If the Alert LED does not go out following start up, but illuminates 
continuously, this indicates that the software has detected a possible 
fault with the hardware. Remove power from the Access Point, wait 
10 seconds and then re-apply power. If the Alert LED comes on 
continuously again, then a fault has been detected. Locate the copy of 
the Access Point software on the accompanying CD-ROM or 3Com 
web site (

) and upload it to the Access Point to 

see if this clears the fault (refer to “Recovering from Corrupted 
Software” below). If this does not fix the problem, contact your 
supplier for further advice.

If the Alert LED remains permanently on following power-up, it is possible 
that the system software has become corrupted. In this condition, the 
Access Point will enter a “recovery” state; DHCP is disabled, and the LAN 
IP address is set to 192.168.1.1. Follow the instructions below to upload 
a new copy of the system software to a Access Point unit in this state.
