Owner's Manual

• Some homes and most offices are steel-framed structures. The steel in such buildings may interfere with your network
radio signals, thus causing a slowdown in the data transmission rate. Try moving your computer to different locations in
the building to see if performance improves.
The computers are not communicating with the network.
• Be sure that you follow all of the steps for connecting to a network (see
Connecting to a Basic Network or Creating an
Ad Hoc Network Using Windows WZC, Connecting to a Basic Network or Creating an Ad Hoc Network Using Wireless
Network Wizard, Connecting to an Advanced Network Using Windows WZC, or Connecting to an Advanced Network or
Creating an Ad Hoc Network Using DW WLAN Card Utility).
• Ensure that your computer is receiving a good signal from the wireless router/AP (see
Performing Network Tasks Using
DW WLAN Card Utility).
• You may have to disable or uninstall firewall software to be able to connect.
• Try changing the channel on the wireless router/AP to channel 1 and retest. If the problem persists, change the channel
to channel 11 and retest. If the problem persists, change the channel to channel 6 and retest.
• Move your computer or your wireless router/AP so that there is an unobstructed path between the two devices.
• Check the cable from the network port to the wireless router/AP and ensure that the power light on the front of the
wireless router/AP is on.
The signal strength of my wireless network connection is marginal or weak.
• Move your computer closer to the wireless router/AP.
• Microwave ovens and some cordless phones operate at the same radio frequency as the DW WLAN Card. When the
microwave oven or cordless phone is in use, it interferes with the wireless network. It is recommended that you keep
your computer at least 20 feet away from your microwave oven and any cordless telephone that operates at a
frequency of 2.4 GHz.
• Try changing the channel on the wireless router/AP to channel 1 and retest. If the problem persists, change the channel
to channel 11 and retest. If the problem persists, change the channel to channel 6 and retest.
• Move your computer or your wireless router/AP so that there is an unobstructed path between the two devices.
My wireless network connection is not receiving a signal on a previously-working network.
• The computer is trying to establish an initial connection but has not yet succeeded. Wait.
• You may have moved out of range of the wireless router/AP. Move closer to the wireless router/AP.
I am unable to connect to a network that uses a certificate.
• The certificate may be invalid. To obtain a new certificate, see
Obtaining Certificates.
• If the network uses a TPM certificate,
Trusted Platform Module (TPM) must be enabled for you to connect. Refer to the
TPM documentation that came with your computer for information about enabling TPM.
• The purpose of the Logon or identity box on the Client Identity tab in Wireless Network Connection Settings is
to override the default behavior when users opt to use their user name and password to log on. This capability can be
important with tunneling protocols such as TTLS and PEAP. Some AAA servers can be configured to require that the
outer tunnel have a different identity than that of the inner tunnel. If this is the case, users must supply the
information in the Logon or identity box.
Even after I insert my smart card, I am still prompted to insert the smart card.
