D-Link DWA-645 User Manual
Section 5 - Troubleshooting
Make sure that the DWA-645 Wireless Adapter is properly seated in the computer’s cardbus slot.
If Windows does not detect the hardware upon insertion of the adapter, make sure to completely remove drivers that
were previously loaded.
2. The computer does not recognize the DWA-645 Wireless Adapter.
• Check that the LED indicators for the broadband modem are indicating normal activity. If not, there may
be a problem with the broadband connection.
• Check that the LED indicators on the wireless router are functioning properly. If not, check that the AC
power and Ethernet cables are firmly connected.
• Check that the IP Address, subnet mask, gateway, and DNS settings are correctly entered for the
network
• In
Infrastructure
mode, make sure the same
Service Set Identifier
(SSID)
is specified on the settings
for the wireless clients and access points. The
SSID
factory default setting for D-Link products is
dlink.
(Double-click on the WLAN icon in the taskbar. The
Link Info
screen will display the SSID setting.)
• In
Ad-Hoc
mode, both wireless clients will need to have the same
SSID
. Please note that it might be
necessary to set up one client to establish a
BSS (Basic Service Set)
and wait briefly before setting
up other clients. This prevents several clients from trying to establish a
BSS
at the same time, which
can result in multiple singular
BSSs
being established, rather than a single
BSS
with multiple clients
associated to it.
3. The computer with the DWA-645 installed is unable to connect to the wireless network and/or the Internet.
