44D-Link DWA-140 User Manual
Section 5 - Troubleshooting
Make sure that the DWA-140 Wireless Adapter is properly seated in the computer’s USB port.
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-140 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 rmly 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 Identier (SSID) is specied on the settings
for the wireless clients and access points. The SSID factory default setting for D-Link products is default.
(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 briey 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-140 installed is unable to connect to the wireless network and/or the Internet.
