Dell 2300 Wireless Broadband Router - Manual (Page 13)

The computer's subnet mask should be the same as the access point's subnet mask.
The computer's gateway IP address should match the IP Address for the access point.
Make sure the IP address assigned by your ISP matches the DNS IP address for your computer.
For dynamic IP addresses:
Make sure your computer has successfully acquired an IP address from the DHCP server. Open a DOS command
prompt, type ipconfig, and the press <Enter>.
Compare the network portion of the address for the computer with that of the access point. The computer's IP address
begins with 192.168.2. To find the current IP address for the access point, start the web-based configuration tool. Click
the Device Status tab.
NOTE: It is recommendable to configure the devices connected to the WLAN to acquire their IP settings from
the DHCP server dynamically.
If I do not have a broadband connection, what do I do?
It's recommended that you subscribe to a Broadband service from your local ISP for Internet connectivity and then try the
setup again. However, if your need is to connect additional wireless or wired computers to the existing local network or to
create a new isolated local network, you can configure your TM 2300 router as an access point. To configure the router as an
access point, refer to the
How to switch to an Access Point mode section in the User's Guide.
