What variables may cause my wireless products to lose reception?
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.
5.
Why does my wireless connection keep dropping?
Antenna Orientation- Try different antenna orientations for the DI-784. 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 secu-
rity systems, ceiling fans, and lights, your wireless connection will degrade dra-
matically or drop altogether. Try changing the Channel on your Router, Access
Point and Wireless adapter to a different Channel 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.
Make sure that the SSID on the Router and the Wireless Client are exactly the same. If
they are not, wireless connection will not be established. Please note that there are two
separate SSIDs for 802.11a and 802.11g. The default SSID for both 802.11a and 802.11g
is
default
.

Why can’t I get a wireless connection?
To establish a wireless connection, while enabling Encryption on the DI-784, you must
also enable encryption on the wireless client.
For 802.11a, the Encryption settings are: 64, 128 or 152 bit. Make sure that the
encryption bit level is the same on the Router and the Wireless Client.
For 802.11g, the Encryption settings are: 64, 128, or 152 bit. Make sure that the
encryption bit level is the same on the Router and the Wireless Client.
