Failing to configure router

Changing TCP/IP settings Win 7 TCP/IP defines how your computer communicates with other computers.
To make it easier to manage TCP/IP settings, we recommend using automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network, if your network supports it. If you use DHCP, then you don't have to change your TCP/IP settings if you move your computer to another location, and DHCP doesn't require you to manually configure TCP/IP settings, such as Domain Name System (DNS) and Windows Internet Name Service (WINS). To enable DHCP or change other TCP/IP settings, follow these steps:

1. Open Network Connections by clicking the Start button , and then clicking Control Panel. In the search box, typeadapter, and then, under Network and Sharing Center, click View network connections.
2. Right-click the connection that you want to change, and then click Properties. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click the Networking tab. Under This connection uses the following items, click either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click Properties. The Network Connection Properties dialog box
4. To specify IPv4 IP address settings, do one of the following:
   • To get IP settings automatically using DHCP, click Obtain an IP address automatically, and then click OK.
   • To specify an IP address, click Use the following IP address, and then, in the IP address, Subnet mask, and Default gateway boxes, type the IP address settings.
5. To specify IPv6 IP address settings, do one of the following:
   • To get IP settings automatically using DHCP, click Obtain an IPv6 address automatically, and then click OK.
   • To specify an IP address, click Use the following IPv6 address, and then, in the IPv6 address, Subnet prefix length, and Default gateway boxes, type the IP address settings.
6. To specify DNS server address settings, do one of the following:
   • To get a DNS server address automatically using DHCP, click Obtain DNS server address automatically, and then click OK.
   • To specify a DNS server address, click Use the following DNS server addresses, and then, in the Preferred DNS server and Alternate DNS server boxes, type the addresses of the primary and secondary DNS servers.
   The Internet Protocol Version 4 (TCP/IPv4)Properties dialog box
7. To change advanced DNS, WINS, and IP settings, click Advanced.

The Linksys Wireless router is fine, but your latop is not configured for DHCP (Dynamic Host Configuration Protocol). The computer is connected to the router at layer 2, whereas HTTP (Hypertext Transfer Protocol), sits
atop the TCP/IP (Transmission Control Protocol/Internet Protocol) layer, and seems to be trying to
query the ISP's (Internet Service Provider) network for a nameserver (via DNS (Dynamic Name Service) protocol) that doesn't exist on the ISP's network. Configuring the laptop for DHCP and specifying no nameserver will fix this (the ISP's network will dynamically assign a DNS).

Its also possible (though a remote possibility) that your Linksys wifi router may be configured to disallow TCP/IP virtual circuits to/from your computer's IP address - but this is a really advanced
capability of your Linksys wifi router - few know this capability even exists.

Connecting multiple wifi devices to the Linksys router should be no problem, just configure them all to interact with the router using DHCP.

Chapter 1: Connecting the Wireless-G Broadband Router

Hardware Installation

1. Locate an optimum location for the Broadband Router. The best place for the Broadband Router is usually at
the center of your wireless network, with line of sight to all of your mobile stations.
2. Fix the direction of the antenna. Try to place it in a position that will best cover your wireless network.
Normally, the higher you place the antenna, the better the performance will be. The antenna's position
enhances the receiving sensitivity.
3. Connect a standard Ethernet network cable to the Broadband Router’s Internet port. Then, connect the other
end of the Ethernet cable to your Cable or DSL Broadband modem.

4. Connect your network PCs or Ethernet devices to one of the Broadband Router’s numbered ports with a
standard Ethernet network cable.

5. Connect the AC Power Adapter to the Broadband Router's Power Socket and the other end into an electrical
outlet. Only use the power adapter supplied with the Broadband Router. Use of a different adapter may result
in product damage.


Chapter 2: Configuring the PCs

Overview
The instructions in this chapter will help you configure each of your computers to be able to communicate with
the Router.
To do this, you need to configure your PC’s network settings to obtain an IP (or TCP/IP) address automatically, so
your PC can function as a DHCP client. Computers use IP addresses to communicate with the Router and each
other across a network, such as the Internet.
First, find out which Windows operating system your computer is running. You can find out by clicking the Start
button. Read the side panel of the Start menu to find out which operating system your PC is running.
You may need to do this for each computer you are connecting to the Router.
The next few pages tell you, step by step, how to configure your network settings based on the type of Windows
operating system you are using. Make sure that an Ethernet or wireless adapter (also known as a network
adapter) has been successfully installed in each PC you will configure.

Configuring Windows 98 and Millennium PCs

1. Click the Start button. Select Settings and click the Control Panel icon. Double-click the Network icon.
2. On the Configuration tab, select the TCP/IP line for the applicable Ethernet adapter.
Do not choose a TCP/IP entry whose name mentions DUN, PPPoE, VPN, or AOL. If the word TCP/IP appears by
itself, select that line. Click the Properties button.
3. Click the IP Address tab. Select Obtain an IP address automatically.
4. Now click the Gateway tab, and verify that the Installed Gateway field is blank. Click the OK button.
5. Click the OK button again. Windows may ask you for the original Windows installation disk or additional files.
Check for the files at c:\windows\options\cabs, or insert your Windows CD-ROM into your CD-ROM drive and
check the correct file location, e.g., D:\win98, D:\win9x, etc. (if “D” is the letter of your CD-ROM drive).
6. Windows may ask you to restart your PC. Click the Yes button. If Windows does not ask you to restart, restart
your computer anyway.

Configuring Windows 2000 PCs

1. Click the Start button. Select Settings and click the Control Panel icon. Double-click the Network and Dialup

2. Select the Local Area Connection icon for the applicable Ethernet adapter (usually it is the first Local Area
Connection listed). Double-click the Local Area Connection. Click the Properties button.
3. Make sure the box next to Internet Protocol (TCP/IP) is checked. Highlight Internet Protocol (TCP/IP), and click
the Properties button.
4. Select Obtain an IP address automatically. Once the new window appears, click the OK button. Click the
OK button again to complete the PC configuration.
5. Restart your computer.
