	        NOTE: 	If you have previously installed an AirSurfer or an 
	        AirSurfer Plus PC Card on your computer please follow the 
	        instructions in the Network Driver Removal section in the 
	        manual before proceeding with the installation.

      into your PCMCIA Slot.

      then type in A: when prompted.
  9.  Select the "BayStack 650 or BayStack 660 Wireless LAN in 
      802.11 Mode Adapter" option, depending on which adapter you are using.
  10. When the BayStack 650 or BayStack 660 adapter configuration
      dialog box appears, select the appropriate values for your SSID
      (default = "Default SSID") and DS Preferred Channel (default =
      "1").  If you do not know which values to choose, contact your
      network administrator.  Improper values will result in a failure
      to communicate with the wireless LAN.
  11. Click OK. The appropriate files will then be copied to your laptop.
  12. Go to the Protocol tab. Add the appropriate protocol(s) for your network. 
      Contact your network administrator if you have any questions regarding

  13. Click "Yes" when prompted to restart your computer.
  14. When Windows NT restarts, the BayStack 650 or BayStack 660
      Adapter will be operational.  Look for the green link integrity
      LED on the BayStack 650 or BayStack 660 PC Card.  This indicates
      a connection with an 802.11 compliant Access Point (when setup in
      Infrastructure mode) or another 802.11 Wireless LAN Adapter (when
      setup in Ad Hoc/Independent BSS mode).

Note: 802.11 specificies two different RF modulation techniques as part
of the standard: Direct Sequence and Frequency Hopping.  These two
techniques are not compatible with each other, even if shipped from the
same vendor.  The BayStack 660 PC Card is a Direct Sequence card.  The
BayStack 650 is a Frequency Hopping card.
