Troubleshooting (continued)
6. The computer with the DWL-520 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-LinkAir and AirPlus 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.
