Q3: I am unable to access the Internet using the DWL-520+.
A1: Check that the LED indicators for the broadband modem are indicating normal
activity. If not, there may be a problem with the broadband connection.
A2: 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.
A3: Check that the IP address, subnet mask, gateway, and DNS settings is correctly
entered for the wireless adapter in that specific wireless network.
Q4: I forgot my Encryption key.
A: Reset the Access Point to its factory default settings and restore the DWL-520+
Wireless PCI Adapter to the factory default settings.

Once properly installed the DWL-520+ Wireless PCI Adapter will be able to connect
to other 802.11b wireless adapters, routers and access points. The DWL-520+ using
