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.
Table "LED Activity" provides an overview of the various modes of operation and the associated LED activity. Table "LED Activity" also includes a number of troubleshooting hints, if required, that may help you solve the problem.
Card is powered on, but set to power saving mode, to conserve battery life.
Flashes indicates that the card wakes up at regular intervals to verify if there is
wireless data addressed to your computer.
Both LEDs blink once every 10 seconds
The PC Card works fine, but did not yet succeed establishing a
wireless connection with the wireless Infrastructure.
Actions:
Check Network Name and Encryption Key
Check your AP1100
Off
Off
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.
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 Windows system tray 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.
Computers seem to be communicating, but don't appear in the My Computer
window or in the Network Neighborhood window
Check that File and Printer Sharing is enabled on all the computers on
your network. On each computer's Start menu, select Settings and click Control Panel. In
the Control Panel window, double-click the Network icon. In the Network window, click the
Configuration tab. You should see File and Printer Sharing at the bottom of the window. If
File and Printer Sharing is not there, click Add, click Service, select Microsoft, and
double-click File and printer sharing for Microsoft Networks. Next, click the File and
Print Sharing button in the Network window. Select both check boxes in the File and Print
Sharing window and click OK. File and Printer Sharing should appear in the Configuration
window list.
Check that the NetBEUI protocol is installed and set up correctly on all
the computers on your network. On each computer's Start menu, select Settings and click
Control Panel. In the Control Panel window, double-click the Network icon. In the Network
window, click the Configuration tab. You should see the NetBEUI protocol. If the NetBEUI
protocol is not there, click Add, click Protocol, select Microsoft, and double-click
NetBEUI. NetBEUI should appear in the Configuration window.
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 an AP1100, check all cables and make sure the power
LED on the front of the AP1100 is green.
