If this is not too imposing, could you perhaps also send a copy of the installation of the Intel 2200BG  card to me? I would much appreciate it!


I hope the others on this list will forgive me, but I'll post the details here (now with the correction from Neil - thanks for spotting that about the 1802 fix), so that Lothar (and perhaps others) may get some use out of this.

A couple of addendum to the original instructions at the bottom of this
note (I'll have to merge these and reformat this to be more readable at
some point).

 If you are using a Centrino chipset based Thinkpad laptop,  or one
that has the Intel Speedstep technology (I think this is only the
Centrino systems but I could be wrong), Turn off this feature in the
BIOS. If you don't the WiFi card will work when connected to AC but not
when on battery !

Process for a T42 is as follows - other models may be similar:

Power on T42,

Press F1 to enter BIOS

enter hardware admin password to the first prompt
and HD password to the second prompt (if you have these set).

press enter when on "Config"

move the cursor down and press enter when on "power"

You can set all values on this screen as follows (you have to scroll
down for about the last 30% as they're off the bottom of the screen):

Power Mode for AC                      Maximum Performance
Power Mode for Battery                 Maximum Performance
Processor Speed                        Fixed Max
Suspend timer                          Disabled
LCD off timer                          Disabled
HDD off timer                          Disabled
Hibernate by timer                     Disabled
Timer Wake with Battery Operation      Disabled
Low Battery Action                     Suspend
Suspend when LCD is closed             No Suspend
Suspend/Hibernate while docked         Disabled
RediSafe                               Disabled
Resume on time                         Disabled
  Resume Time                          00:00:00
  Resume Date                          00/00/0000
Resume on Modem Ring                   Disabled
Intel (R) SpeedStep technology         Disabled
  Mode for AC      (Grayed out)        Automatic
  Mode for Battery (Grayed out)        Battery Optimized
Screen Blanking                        Disabled
Power Switch Mode                      On/Off
Suspend to hibernation                 Disabled
CDROM Speed                            Normal
CPU Power Management                   Disable
PCI Bus Power Management               Disable

F10 to save and exit

This instruction turns of ALL power saving components however of all of
these settings we have found that the relevant ones are the Intel
Speedstep and CPU Power Management settings.

We are further investigating this problem as having power management
turned off on a laptop while on battery is not ideal. It is possible
that with a more "speedstep friendly" version of the OS/2 Kernel, the
2200BG card could work with the power saving settings turned on.


Please read this as an addendum to my previous documentation.

In that documentation, I suggested that you let WLANMON configure the
TCPIP port rather than using TCPCFG2 - this is also what the readme for
WLANMON says is more reliable.

My findings are in fact the opposite.

Configure the TCPIP port for your WifI and your cabled connection in
TCPCFG2. Note: you can only assign DHCP to one port using this program,
so you will need to assign a static address to either your LAN cabled
connection or your WiFi connection (we were doing this via WLANMON
anyway, so we really only doing this in another place).

 It would be nice to have DHCP running on both ports - "watch this
space" I believe it will be possible by simply editing SETUP.CMD - but
lets leave that one for now ...

 Once you have enabled lan1 in TCPCFG2 and given it an IP address and
subnet mask, go to the WLANMON ICON - RMB and select ADD/EDIT profile,
make sure your profile is highlighted - I guess you only have one at
this point in time, so it will probably be highlighted already, press Edit,
On the Connection TAB - unclick the Create a network if one is found.
On the TCP/IP TAB - click on don't configure.
Leave the security tab as is.

Close this properties book.

Press close on the "select a profile" panel.

RMB on the ICON and exit.

Close down and restart your system.

Click on Wireless LAN Monitor and hopefully she'll turn Green every time
from now on !


Now that I have got this working, here is the documentation that I promised:

NOTE: This process is not perfect !

 I wanted to ensure the process was repeatable - it's not 100%, however
as it has worked and proved that both the hardware and the GenMac driver
appear to work as expected (the issues are around TCPIP configuration
and how it interfaces to WlanMon as far as I can see), I wanted to pass
this information on.

Since others have said they haven't been able to even get their cards
working at all, I felt this process may be of use to them. Also the more
people testing, will isolate the issues affecting operation that much

The first time this process was followed it worked perfectly, the second
time, it failed until I removed TCPBEUI (which had worked previously),
the third time no matter what I did in the TCPIP and WlanMon
configurations, I could not get it to work, the forth time, it worked
correctly again.



  Without any card installed in the MINI-PCI slot - 1802 Bios fix run to allow the IBM hardware to accept this Toshiba branded Mini_PCI card. (The patch removes the hardware check).

  Intel 2200BG MINI-PCI Card Installed.

  CMOS (BIOS) Settings - no changes - default settings.

1. Download the required software;

   GENMAC Wrapper Version 1.00 and v 1.6 upgrade package.

   WLANMON v 2.12

   (There are later versions - use at your own risk - this process used
    these versions).

2.  Clean-up Stage (Skip this if this is your first install attempt).

    MPTS - Remove protocols from 2200BG card
         - Remove any SVista or VPC virtual network protocol drivers
           (on any card)
         - Remove NIC definition for 2200BG card.
         - Adjust any remaining card to be the first adapter.

    CONFIG.SYS - Rem out all Uniaud lines.
               - Rem out all virtualPC lines.
               - Delete the Run Helperw.exe line

    OS2.INI - Using either REGEDIT2 or inimaint (or similar INI editor),
              Delete the following four keys from
                  Wireless Lan monitor:Networks
                  Wireless Lan monitor:Profiles
                  Wireless Lan monitor:Properties
                  Wireless Lan monitor:Stream Profiles
       (these should be the only "wireless" entries that are present).

    DESKTOP - Delete Wireless LAN Monitor folder and any shadows or
              copies you made of it or its contained objects.
              (if you installed Wlanmon as a Widget previously -
                delete the widget).

    --  REBOOT the system --

    DISK - Delete the complete GENMAC directory tree - normally written
           to the system root drive.
         - Delete any directories you created to install (x)wlanmon into

3. Check Status.

   Make sure your other (Non WLAN) network connection is working

     Check configuration in MPTS
     Check condiguration in TCPCFG2
     Check configuration in LANINST

   Note: You should have LAN interface zero and the loopback interface
         configured normally in TCPCFG2 - we will not configure the WLAN
         interface here, rather we let WLANMON do this for us.

    -- COLD RESTART --

    Check no errors are indicated on boot up and that communication is
    working on your non-WLAN NIC.

4. Install GENMAC driver.

   Go to the temporary directory where you downloaded the code into and
   create a sub-directory for GENMAC. e.g. if you downnloaded to E:\TEMP
   create E:\TEMP\GENMAC

   Unzip the GENMAC v 1.00 Zip file into this new subdirectory.
   Unzip the GENMAC v 1.6 zip package into the SAME subdirectory.

   Go into the subdirectory and execute the INSTALL.CMD file. This will
   create a directory tree called \GENMAC off the system root, load
   the required NIF and MAC files into \IBMCOM\MACS and add a line to
   the start of CONFIG.SYS for the HELPERW.EXE program.

   Run MPTS and select and add the INTEL WLAN 2200BG as the next NIC in
   the configuration (i.e. if your onboard ethernet connection is the
   first NIC, make this the second NIC.)

   Now add ONLY the TCPIP protocol to the 2200BG NIC (if you need
   additional protocols, add them once the card is working - often TCPIP
   is all you need). Check the protocol number allocated to the TCPIP
   protocol does not conflict with any existing number - normally it
   would have a protocol number of 1. If there is a conflict adjust to
   avoid this by using the "change number" button.

   Still from within MPTS, edit the 2200BG card settings:
    Make Network Name (SSID) either blank or the name of your access
     point (this field is case sensitive).
    Change Debug Level from "NO" to "NONE".
    Change Wrapper Options from "NO" to "STACK32".

   Exit MPTS and save everything, letting CONFIG.SYS be updated.

   -- SHUT DOWN and COLD BOOT the system --

   On reboot - check that the card is indicated as having it's driver
   loaded, this text is in red and must also indicate that it is version
   1.6. - Should say "loaded for device ....".

   (Note: If you find that you have the wrong version of GENMAC, you
          cannot simply copy over HELPERW.EXE and GENM32W.OS2 - the
          copy will not give an error, but the file will not change as
          it is locked - you will need to run the "Unlock" program (in
          the GENMAC package, in the \BIN subdirectory) first and then
          replace these files.

   If the driver does not load at this point, this could suggest a
   faulty card.

5. Install WLANMON.

   Firstly it is important to note that we will install the EXE version
   and NOT the widget.

   Create a directory to hold WLANMON e.g. E:\WLANMON and unzip the
   (v2.12) package from the temporary directory where you downloaded it
   to this new directory.

   Execute the INSTEXE.CMD file from this directory, it will install the
   program in its current location and create a folder on the desktop.

   Start the wireless Lan Monitor and you will see a welcome screen and
   a flashing small ICON.

   Press OK.

   Now drag the ICON to a better place on the desktop and right mouse
   button (RMB)click it. I don't like this small ICON so I always select
   Window and click on Large Window Size. Then again Window and "always
   stay on top".

   If you are happy with the small icon, these two actions are optional.

   Now we will set the overall properties, so RMB - Properties.

   Radio tab - Set activate radio on startup
   Connection scan tab - Set scan for connections on startup
                       - change interval and retries to something more
                         sensible - default is 2/3600, I use 4/15.
   Device tab -this must show "Genmac wrapper INTEL 2200WLAN [8086:4220]
               and version WIND32$ 1.06, if not either the card is
               faulty or you have missed/incorrectly actioned an
               instruction above.
   TCP/IP tab - click Execute LAN config on disconnect - on.
              - leave Conflict at "prompt user".
   Script tab - leave both options ON, even though the scripts don't
   Mouse Actions tab - Leave as set (next profile / Scan).
   Error handling tab - Leave all three options selected.
   Display tab 1 - Leave as set (system value / 0)
   Display tab 2 - Info only.
   Information tab - must indicate v 2.12.

   Exit properties and RMB on the ICON again
    - Select ADD/EDIT Profile then NEW ....
      Connection tab 1 - Enter a Profile name - e.g. HomeWiFi
                       - Leave Connect as Basic ......
                       - click on "create a network"
                       - click on "include in connection scan"
                       - enter the SSID of your access point in the
                         network name field.
      Connection tab 2 - is greyed out.
      Security tab 1 - Encryption - in my case this was WEP64
                       Enter the key number set to be used with
                       your access point(AP) (1,2,3 or 4) - check your
                       AP for what you set it to.
                       Either generate using a known passphrase or
                       enter all four keys manually.
      TCP/IP tab - Although most access points also work as DHCP servers
                   during this initial set up stage I prefer to give the
                   system a static IP address. To do this, click on
                   "configure manually", enter the IP address and subnet
                   mask, Click on "more TCP/IP options" and enter the
                   default gateway IP address.

      Close this new profile and then press close on "select a profile"

      RMB on the ICON again, click on "select profile" and then the
      profile you just created (this should be the only one available.

      RMB on the ICON and click on "scan for connection".

      RMB one last time on the ICON and select EXIT to close WLANMON.

      -- SHUT DOWN, POWER OFF and RESTART the laptop --

6. Testing

   If you are lucky, once the system has fully booted, if you click on
   WLANMON the icon will load and go green - you have connectivity !

   In this state the reset TCPIP configuration option in the ICON RMB
   menu will be selectable - this is grey until the connection is
   Also you will be able to do a scan of hotspots, set the type to all
   and you will see your access point and possibly others in your area

   If you do not get into a connected mode, you can try the following

    Remove TCPBEUI and Netbios from your onboard NIC and restart.

    Change WLANMON not to allocate a static IP address but rather to use

    Change Wrapper to be the first NIC and the onboard to be the second.

    Any and all TCP/IP configuration changes whether through TCPCFG2 or
    the profile in WLANMON REQUIRE you to do a reboot of the system
    before they will "settle in".

    Once you have the system working, a small change like adding in DNS
    addresses can stop the link working AND backing out the change
    DOES NOT return the link to operation ! The only way I have found
    around this is to delete the four OS2.INI entries and then re-
    configure WLANMON again.

    This lets me conclude that the area that is less than perfect is
    WLANMONs configuration of TCPIP and this stops the WiFi connection
    from working at all.

    It may be better to manually configure this TCPIP connection in
    TCPCFG2 and disable the "create a network" in connection tab 1 of
    the profile properties, however the notes with this software
    recommend not to do this.


Again, I would like to stress that this process is not 100% ! I am not
the developer of the driver or application and as such, I cannot do more
than document my findings. The key finding is that this hardware DOES
work under eCS 2.0B2. This hopefully is a good starting point to clarify
the last few variables to get the solution stable.
