Troubleshooting (continued)
6. The computer with the DWL-AG660 installed is unable to connect
to the wireless network and/or the Internet.
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 the 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 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.
A. Under Tools> select Folder Options...> select View >
under Hidden files and folders > select Show hidden

B. Uncheck Hide extension for known file types > click
on Apply.
C. Search for previously loaded driver files. Remove these
files from the INF and SYSTEM32 (DRIVERS) folders in
the Windows directory. Note: Windows XP and Windows
2000 will rename .inf files that have not received WHQL
certification into oem.inf files (e.g., oem1.inf).
