If you encounter difficulty using and/or installing your
TrueMobile 1150 product, the error may be related to
various causes:
Out-of range situation, which prevents the
TrueMobile 1150 PC Card from establishing a
wireless connection with the network.
Configuration mismatch, which prevents the
TrueMobile 1150 PC Card from establishing a
wireless connection with the (correct) network.
Absence of, or conflict of the TrueMobile 1150
Driver.
A problem or conflict with the PC Card slot which
prevents the PC Card from powering on.
A conflict of the TrueMobile 1150 hardware with another
device.
The starting point to troubleshoot problems with your TrueMobile 1150 PC Card is looking at the LED activity of
the TrueMobile 1150 PC Card.
LED Activity Table provides an
overview of the various modes of operation and the associated LED activity and
includes a number of troubleshooting hints.

Card is not powered on, so it can not transmit/receive
data.
The cause may either be:
No Driver loaded/installed
Card - Driver mismatch which prevented the driver
from loading
Device conflict which prevented the driver from
loading
Actions:
Verify if a driver has been installed, if not install
the driver.
Verify the device settings of the PC Card to
determine the occurrence of a conflict with another
device. If so, change the settings of either your
PC Card or the conflicting device to resolve the
problem.
Verify the versions of the driver, and the embedded
software in the PC Card (also referred to as Station
firmware).
Cannot Connect To The Network
If your PC Card seems to be working fine, but you are not
able to connect to the network, this error might be due to a
configuration mismatch.
For example if both LEDs of your PC Card blink once every ten
seconds, the problem is likely to be caused by a configuration
mismatch of:
Network Name
Encryption Key
The TrueMobile 1150 Network Name and Encryption Keys are case-sensitive. Be sure that these values are exactly the same on all computers.
LEDs Work But Cannot Connect to Network
If you cannot connect to the network while the LEDs indicate that
the network is working properly (Power LED is on, Transmit Receive
LED blinks) probably the TCP/IP settings of your network are not
properly set.
Changing TCP/IP Settings
To change the TCP/IP Settings:
On the Microsoft® Windows® task bar click the Start button.
Select Settings and then select Control
Panel.
On the Control Panel window, double click on the
Network icon to view the Network Properties.
From the list of installed components, check if the TCP/IP
-> TrueMobile 1150 PC Card protocol is
installed.
If this protocol is not yet installed, click the Add
button and select the TCP/IP protocol from the list. Refer
to the Windows Help for more information
When prompted, restart your computer.

Data transfer
is sometimes very slow
Microwave ovens
and some cordless phones operate at the same radio frequency
as the Dell TrueMobile 1150 Series LAN cards. When the
microwave or cordless phone is in use, it interferes with
the Wireless Network. Keep computers with TrueMobile 1150
Series cards at least 20 feet away from your microwave oven
and any cordless telephone that operates at a frequency of
2.4 GHz.
Data transfer
is always very slow
Some homes and
most offices are built with steel. The steel in your
building may be interfering with your network's radio
signals. Try moving your computers to different locations to
improve performance.
Computers won't
communicate with the network
If your network
has a Residential Gateway, an access point or, a wireless base station, check all cables and make sure the power LED
on the front of the device is Green.
