28 D-Link Systems, Inc.
D-Link products let you access your network from virtually anywhere you want. However, the positioning of the products within your environment
will affect the wireless range. Please refer to Installation Considerations in the Wireless Basics section of this manual for further information
about the most advantageous placement of your D-Link wireless products.
9. Why can’t I connect the DGL-3420 to my network?
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 default.
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.
Check that the Network Connection for the wireless client is configured properly. Select Infrastructure when connecting to a wireless router
and select Ad-Hoc mode when connecting without an access point.
If security is enabled, make sure that the correct encryption key or passphrase is entered on both the DGL-3420 and the wireless router or Ad-Hoc
client.
10. What variables may cause my wireless products to lose reception?
11. Why does my wireless connection drop?
Antenna orientation – try different antenna orientations for the DGL-3420. Try to keep the antenna at least 6 inches away from the wall or other
objects.
If you are using 2.4GHz cordless phones, X-10 equipment or other home security systems, ceiling fans, and lights, your wireless connection
will degrade dramatically or drop altogether. Try changing the channel on your router, access point and all other devices on the network to avoid
interference.
Keep your product away (at least 3-6 feet) from electrical devices that generate RF noise, like microwaves, monitors, electric motors, etc.
