ISA Bus Switch Settings:

To install the adapter in a computer with an ISA bus, set the DIP switches as shown below.

Table 5 ISA Dip Switch Setting  (Switch 1-8)

 Switch       1    2    3    4    5    6    7    8
 Position    Off  Off  Off  Off  Off  Off  Off   ON


  Refer to the values shown on the ISA adapter, DO NOT use the values shown on the switch.

The settings shown in Table 5 apply to most computer configurations. The interrupt level used by the IBM Wireless LAN adapter is determining by the position of switches 5 and 6.

The IBM Wireless LAN adapter does not support interrupt level sharing. Therefore, make sure that no other adapter in the computer uses the same interrupt level. If necessary, change the interrupt level of the IBM Wireless LAN adapter.

If you want to use interrupt level 9 for the IBM Wireless LAN adapter, make sure that no other adapter in the computer uses interrupt level 2.

ISA Mode Operations Parameters:

The following provides the possible values for ISA mode operation parameters that you can select according to the system configuration.

•  Input / Output (I/O) base address (this is used by the computer to identify and  communicate with each individual adapter).

Switch Positions 1 2 3	I/O Base Address
0 0 0	86A0
1 0 0	96A0
0 1 0	A6A0
1 1 0	B6A0
0 0 1	C6A0
1 0 1	D6A0
0 1 1	E6A0
1 1 1	F6A0

•  RPL memory enable (this allows to enable or disable the RPL memory).

Switch Position 4	RPL Memory
0	Disabled
1	Enabled

•  Interrupt level (this establishes the priority by which the adapter can  interrupt the computer. The lowest value is given the highest priority).

   To use interrupt level 9 for the IBM Wireless LAN adapter, make sure that no other adapter in your computer uses  interrupt level 2.

Switch Positions 5 6	Interrupt Level
0 0	9
1 0	10
0 1	11
1 1	15

•  Direct Memory Access (DMA) arbitration level (this establishes the priority  by which the adapter can access the computer memory. The lowest value is given the highest  priority).

Switch Positions 7 8	ISA DMA Level
0 0	0
1 0	1
0 1	3
1 1	Invalid

Wireless LAN Utilities Diskette:

To use the utilities stored on the IBM Wireless LAN Utilities Diskette, you must add for lines to the CONFIG.SYS  file on the diskette. To do so, take the following steps:

1.  Edit the CONFIG.SYS file supplied on the IBM Wireless LAN Utilities diskette.
2.  Copy the four lines of Card and Socket Services DEVICE statements. These statements are  determined by the type of ThinkPad and are supplied on the ThinkPad utilities diskette.

    For example, in the DOS environment for an IBM ThinkPad 720 computer, the four lines to copy might be:

   DEVICE=C:\IBMDSS02.SYS
   DEVICE=C:\IBMDOSCS.SYS
   DEVICE=C:\DICRMU02.SYS
   DEVICE=C:\$ICPMDOS.SYS

Placement of Radio Modules:

The IBM Wireless LAN Adapter consits of an external unit and a controller card or a PCMCIA Credit Card. The external unit is called Radio Module

The radio module contains the antenna. It is connected by cable to the controller card or the PCMCIA Credit Card.

Considering that each base must be located at the center of the cell it controls, cells should be arranged in a manner to cover the site. The following guidelines for radio module placement ensure reliable operation of the wireless network.

Place the radio modules:

•  So that they are not hidden by metallic objects
•  Far from moving objects such as fans or metallic doors
•  Away from radiation sources that emit in the 2.4GHz frequency band such as  microwave ovens.

   In addition, place the base radio modules:

•  Above the average furniture height, at least 1.5m (5 ft.) above the floor.
•  Above dividing panels, shelves and so on
•  At the center of the ceiling of a large room or corridor, or at the intersection of two corridors.

•  Hardware errors on Wireless LAN controller cards
•  Software errors during data transfer
•  Significant events such as adapter load completion

   These events are logged in two files:

•  IBMWLERL.LOG, which contains the most recent events.
•  IBMWLERL.BAK, which contains older events.

   In an OS/2  environment there is an additional file:

•  LANTRAN.LOG

1.  Insert the IBM Wireless LAN Utilities  diskette in drive A.

   NOTE: If the workstation has a PCMCIA Type II slot, make sure that  you have correctly set up the IBM Wireless LAN Utilities diskette (as decribed above).

2.  Restart the workstation as follows:
   •  For an ISA computer, power-off the computer then power-on the computer
       - or -
     
   •  For Micro Channel or computers with the PCMCIA Type II slot, pressCtrl+Alt+Del

3.  Select Diagnostics Utilities from the main menu.
4.  Wait for the diagnostics to complete and follow the recommended action.

1.  Note the resulting diagnostic message and code.
2.  Go to 'Problem Resolution Worksheet' print and fill in the information on the worksheet.
3.  Then call the IBM service representative or the dealer.

•  If you use Card and Socket Services or only Socket services, you can edit the CONFIG.SYS file and comment out the Card and Socket device statements  (these statements are determined by the type of computer).

   Then press Ctrl+Alt+Del to restart the computer.
   If the problem persists, refer to the following procedure:

•  If you use neither Card or Socket Services, edit the NET.CFG file and add:

  /R :C000
   to the following statement:
  Enabler c:\xxxx\IBMWLENA.EXE
   where C000 is a memory zone between C000 to EF00 in multiples of 100 and xxxx is the directory where the IBM Wireless LAN has been installed,  for example, NWCLIENT.

   Then press Ctrl+Alt+Del to restart the computer.

•  In a Network environment for DOS and Windows workstations, edit the NET.CFG file and specify the following statements:
  •  For interrupt level
    int n
     (n can be 3, 4, 5, 7, 9, 10, 11, 12 or 15).
  •  For I/O Address
    port xxxx
     (xxxx can be from 200 to 2F0, from 300 to 360 or from 400 to FFE0 in multiples of 10).
•  In an OS/2 environment, for DOS and Windows workstations, change these wireless adapter parameters through the LAN Support Program diskette.
