Some of the DELL TrueMobile 1150 Series PC cards floating around
out there contain different vendor IDs which; is causing "failure
to locate driver" and making quite a panic when reinstalling
this PCMCIA card into a new or updated windows xp laptop or just
want to use it on another pc.
This is just a simple way to get the
11Mbps Dell TrueMobile 1150 PCMCIA Wireless LAN Adapter to work
in windows XP. Its a little fix that should make the adapter
perform like intended. These DELL labeled cards were made for
Agere Systems and a couple others. The drivers might work on
Windows 2000 or Me with little changes or you can get earlier
versions of these drivers (1100, 1050, etc) as a free download
from Dell's Support site.
What You"ll Need: Download the file(s): R69901 (drivers) and R69923 (client manager)
from the Dell Support website. You'll only need the drivers
(R69901) if you just want to use this card on your laptop as
normal, and not as a server/monitor.
NOTE: Do not attempt to install this file just yet, you'll
need to modify an information and setup file first. Click or
run the R69901.EXE file and let it place the needed files into
a "Dell/drivers/R69901" folder (or your choice) on
your hard drive. Once you click on the file; it will create the
files needed, and may open the html user file and show you how
to install the drivers for XP but it wont work until you modify
the INF file with your card's ID code. Now open the file "WLDEL48B.INF"
with notepad or some other DOS/TEXT editor make the needed changes
to the device ID line in the file. Be sure it's correct, then
save the file as is. (don't change
the name or the format of the file, or it won't work)...see image below
The information you need to change this
file will come from your windows XP Device Manager . (if no driver
was found or loaded for this device when you first plugged it
in, then it will show as USB "unknown device")
Use the RUN command in your [Start]
window folder and type "devmgmt.msc" and press OK.
double click on the USB device (unknown) and in the Properties
Tab "Details" you'll get the device's ID. there
are several other numbers and stuff, but all you need is the
top one. (four digits).
Thats's all there is. It should now
find your wifi card next time you plug it in, if not point your
"device wizard" or "update driver" to the
dell R69901 folder (or wherever it is) with the INF file you
This is a great little card, and can serve you many more years
of service just remember to save the new driver folder if you
intend to have this for later.
