Assigning a Static IP Address in Windows XP/2000
Note: Many broadband routers will automatically assign IP addresses to the com-
puters on the network, using DHCP (Dynamic Host Configuration Protocol) tech-
nology. 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:

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

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 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 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- 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 your
network) and the DWL-G120 are exactly the same. If they are not, wire-
less connection will not be established. The default SSID is default.

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

1-Year Limited Warranty for the Product(s) is defined as follows:
•Hardware (excluding 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.

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

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.

of D-Link’s products will not be applied to and does not cover any refurbished product and any product
purchased through the inventory clearance or liquidation sale or other sales in which D-Link, the sellers,
