|You can find your router's DHCP address assignment range on its configuration WEB page. The router is your LAN's gateway to the Internet and it's LAN IP address is the same as your local computer's default gateway address.|
Since your Linux box is unable to connect, I will give direction specific to Windows XP:
Open Control Panel
Open the Network Connections dialog.
ALT+Click the Local Area Network icon and select Status in the resulting context menu.
In the Status dialog select the Details tab.
Your router's IP address is the same as the Default Gateway address. Write it down for the next step.
Close all open dialogs then open a WEB browser window.
In the address bar, enter the Default Gateway IP address in the following form:
http://xxx.xxx.xxx (xxx.xxx.xxx represents the Default Geteway IP address written down earlier)
A password dialog will usually open.
Your router's user manual should include the default user name and password unless you have reset this information.
Log into your router's WEB page. From there you can navigate to the DHCP server's configuration page.
Unfortunately each router uses a different arrangement for the configuration WEB page. You should be able to learn where to look in your routers user manual. If you do not have a printed user manual, you should be able to go to the manufacturer's WEB site and download one (usually in pdf format).
I suggest you first confirm that the router's DHCP server is configured to provide enough IP addresses. The usual default configuration on most routers should normally be set to support more than three, but I may be wrong since I have used only two brands. If not, then you may want to try configuring the Linux computer to use a static IP address.
Remember that if the Linux box uses a wireless connection, the issue may not be related to the router at all, but to the Linux box's wireless configuration
Again, more information may prove helpful,
