Assigning a Static IP Address in Windows XP/2000
Note:  Many broadband routers will automatically assign IP addresses to the 
computers  on  the  network,  using  DHCP  (Dynamic  Host  Configuration  Protocol) 
technology. If you are using a DHCP-capable router you will not need to 
assign static IP addresses.
If you are not using a DHCP capable router, or you need to assign a static IP address, 
please follow these instructions:

Input your IP address and subnet mask. (The IP addresses on your network must be 
within the same range. For example, if one computer has an IP address of 192.168.0.2, 
the other computers should have IP addresses that are sequential, like 192.168.0.3 
and 192.168.0.4. The  subnet  mask  must be the same for all the computers on the 
network.)
Input your DNS server addresses. (Note: If you are entering a DNS server, you must 
enter the IP address of the Default Gateway.)
The DNS server information will be supplied by your ISP (Internet Service Provider.)

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 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.
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-G650M, you must also enable 
encryption  on  all  wireless  devices  in  the  network  in  order  to  establish  a  wireless 
connection.
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 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.
The encryption settings are: 64-,128- bit. Make sure that the 
encryption bit level is the same on the router and the DWL-G650M.
Make sure that the SSID on the wireless router (if you have one in your network) 
and the DWL-G650M are exactly the same. If they are not, 
wireless connection will not be established. The default SSID is default.

Warranty 
Subject to the terms and conditions set forth herein, D-Link Systems, Inc. (“D-Link”) provides this Limited 
warranty for its product only to the person or entity that originally purchased the product from:
·  D-Link or its authorized reseller or distributor and
·  Products purchased  and  delivered within  the  fifty  states  of  the  United  States, the  District of 
Columbia,  U.S.  Possessions  or  Protectorates,  U.S.  Military  Installations,  addresses  with  an  APO  or 
FPO. 
Limited Warranty:  D-Link warrants that the hardware portion of the D-Link products described below 
will be free from material defects in workmanship and materials from the date of original retail purchase 
of the product, for the period set forth below applicable to the product type (“Warranty Period”), except 
as otherwise stated herein. 
1-Year Limited Warranty for the Product(s) is defined as follows:
·  Hardware (excluding power supplies and fans) One (1) Year
·  Power Supplies and Fans One (1) Year
·  Spare parts and spare kits Ninety (90) days
D-Link’s sole obligation shall be to repair or replace the defective Hardware during the Warranty Period 
at no charge to the original owner or to refund at D-Link’s sole discretion.  Such repair or replacement 
will be rendered by D-Link at an Authorized D-Link Service Office.  The replacement Hardware need not 
be new or have an identical make, model or part.  D-Link may in its sole discretion replace the defective 
Hardware (or any part thereof) with any reconditioned product that D-Link reasonably determines is 
substantially equivalent (or superior) in all material respects to the defective Hardware.  Repaired or 
replacement Hardware will be warranted for the remainder of the original Warranty Period from the date 
of original retail purchase.  If a material defect is incapable of correction, or if D-Link determines in its 
sole discretion that it is not practical to repair or replace the defective Hardware, the price paid by the 
original purchaser for the defective Hardware will be refunded by D-Link upon return to D-Link of the 
defective Hardware.  All Hardware (or part thereof) that is replaced by D-Link, or for which the purchase 
price is refunded, shall become the property of D-Link upon replacement or refund.
Limited Software Warranty:  D-Link warrants that the software portion of the product (“Software”) will 
substantially conform to D-Link’s then current functional specifications for the Software, as set forth in the 
applicable documentation, from the date of original retail purchase of the Software for a period of ninety 
(90) days (“Warranty Period”), provided that the Software is properly installed on approved hardware 
and operated as contemplated in its documentation. D-Link further warrants that, during the Warranty 
Period, the magnetic media on which D-Link delivers the Software will be free of physical defects.  D-
Link’s sole obligation shall be to replace the non-conforming Software (or defective media) with software 
that substantially conforms to D-Link’s functional specifications for the Software or to refund at D-Link’s 
sole discretion.  Except as otherwise agreed by D-Link in writing, the replacement Software is provided 
only to the original licensee, and is subject to the terms and conditions of the license granted by D-Link 
for the Software.  Software will be warranted for the remainder of the original Warranty Period from the 
date or original retail purchase.  If a material non-conformance is incapable of correction, or if D-Link 
determines in its sole discretion that it is not practical to replace the non-conforming Software, the price 
paid by the original licensee for the non-conforming Software will be refunded by D-Link; provided that 
the non-conforming Software (and all copies thereof) is first returned to D-Link.  The license granted 
respecting any Software for which a refund is given automatically terminates.
Non-Applicability of Warranty:  The Limited Warranty provided hereunder for hardware and software 
of D-Link’s products will not be applied to and does not cover any refurbished product and any product
