For additional help, refer to the users guide for the computer you are using.
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).

priority).

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:
- Edit the CONFIG.SYS file supplied on the IBM Wireless LAN Utilities diskette.
- 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:
Modern buildings having metallic partitions are very common. IBM suggests that you install the base radio modules in the ceiling
of corridors. Radio waves used by the IBM Wireless LAN are reflecting along these partitions, and enter
into offices through the doors or glass parts.
Error Management Overview:
The IBM Wireless LAN software processes the events occurring in each base, such as:
Allthese events are listed in the manual, Installing and Operating Your Network delivered with the product.
The most critical events are reported to the network management system through simple network
management protocol (SNMP) traps, and can be displayed on the network management station.
Using a network management system such as NetView/6000 or
NetWare Management system (NSM) allows to manage the network from a single point.
Running Adapter Diagnostics:
To run the adapter diagnostics, do the following:
- 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).
- 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
- Select Diagnostics Utilities from the main menu.
- Wait for the diagnostics to complete and follow the recommended action.
NOTE: If a hardware problem is not identified, see the Installing and Operating Your Network manual
(part number 54G2072 ) for further information on troubleshooting.
If the problem persists:
- Note the resulting diagnostic message and code.
- Go to 'Problem Resolution Worksheet' print and fill in the information on the worksheet.
- Then call the IBM service representative or the dealer.
PCMCIA Credit Card Problems:
NOTE: The following applies only to PCMCIA Type II slot DOS and Windows wireless workstations in a Netware environment.
If the PCMCIA Credit Card is not detected when you start the computer do the following.
- 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.
NOTE: If you are using only Socket Services you can edit the CONFIG.SYS file and add the Card Services device statement.
Interrupt Level or I/O Address Conflicts
NOTE: The following applies only to PCMCIA Type II slot wireless workstations.
Interrupt levels or I/O address conflicts may occur after you install the IBM Wireless LAN software on a workstation.
If this happens, you can resolve the conflict by changing the value of the interrupt level or the I/O address used by the IBM Wireless LAN adapter. To do so, refer to the following procedures:
- 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.
Checking the Base Configuration (OS/2 Environment)
To verify that all prerequisites have been installed as defined by the configuration for the base, refer to Table 10.
If all the prerequisites have been installed, access (LAPS) MPTS and verify the options, binds and parameters that were selected during installation.
If they are correct, you must re-install.

NOTE:
- Install and bind TCP/IP with the device driver depending on the backbone adapter. If you have a
problem, check the IP connection. To do so, type ping xxxxx at the OS/2 prompt.
- Bind IBM IEEE 802.2 with the device driver of your wireless adapter.
- Bridged configuration:
- MPTS (LAPS)
- Select the IBM Wireless Network Adapter for Base with bridge from the adapter list. Bind with the IBM Wireless LAN Bridge.
- Bind the IBM Wireless Network Adapter with IBM IEEE 802.2
- Select the IBM Token Ring Network Adapter from the adapter list. Bind with the IBM Wireless LAN Bridge.
- Supervisor Bridge option enabled.
IBM Wireless LAN bridge can NOT be installedon the same computer as
Routexpander/2 or Source Routing Bridge.
LAPS Installation Problem:
If you cannot run the IBM Wireless LAN because LAPS aborted during installation, do NOT reboot the computer when prompted by
the instructions displayed on the screen. Go to the OS/2 Install directory and erase the file IBMLANLK.LST, then restart the
workstation.
