39Troubleshooting (continued)2. 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 thewireless range. Please refer to Installation Considerations in the WirelessBasics section of this manual for further information about the most advanta-geous placement of your D-Link wireless products.3. Why does my wireless connection keep dropping?4. Why can’t I get a wireless connection?If you have enabled encryption on the DWL-G120, you must also enable en-cryption on all wireless devices in the network in order to establish a wirelessconnection.If you are using 2.4GHz cordless phones, X-10 equipment or other homesecurity systems, ceiling fans, and lights, your wireless connection willdegrade dramatically or drop altogether. Try changing the channel onyour router, access point and wireless adapter to a different channel toavoid interference.Keep your product away (at least 3-6 feet) from electrical devices thatgenerate RF noise, like microwaves, monitors, electric motors, etc.The encryption settings are: 64- or 128-bit. Make sure that the encryp-tion bit level is the same on the router and the DWL-G120.Make sure that the SSID on the wireless router (if you have one in yournetwork) and the DWL-G120 are exactly the same. If they are not, wire-less connection will not be established. The default SSID is default.
