Assigning an IP address to a computer

A DHCP Reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client.
You can configure a DHCP reservation in your DHCP server when you need to reserve a permanent IP address assignment. You can use these reservations for DHCP-enabled devices like print and file servers or other application servers which always have the fixed IP address on a network.
To configure a DHCP reservation, follow the steps provided below:

Step 1:
Access the router's web-based setup page. For instructions, click here.

Check this tip out from Linksys. It is for a G VPN Router but you could use the same steps to troubleshoot. Title: Resolving Blinking Power or Diag LED on a Linksys Wireless-G VPN Router Article ID: 4982 If the Power LED on your Linksys router is blinking, this means the device is not ready. It should go off once the router completes its diagnostic test. If the Power LED won?t go off, it indicates that there?s a possible hardware problem with the router. To resolve this, you will need to perform five steps: Resetting the Router Assigning Static IP to the Computer Pinging the Router Accessing the Router?s Web-based Setup Page Updating the Router?s Firmware For instructions on how to reset the router, follow the steps below. Resetting the Router Hold in the RESET button at the back of the router for 30 seconds. Unplug the power to the router then plug it back in. If after resetting the router and the Power LED is still blinking, try resetting the router again for another 30 seconds. Then proceed with assigning a static IP address on the PC. For instructions, follow the steps below. Assigning a Static IP Address on Your Computer Most of the time, if the power LED on the router is blinking it loses its ability to assign IP addresses to the PCs connected to it, which is why you need to assign the computer a static IP address. After assigning a static IP address on the computer, check if the computer is still communicating to the router by performing a ping test. To ping the router, follow the steps below. Pinging the Router Ping test helps trace the communication between the computer and the router. The computer sends packets to the router and in return the router sends out replies to validate the connection. In this example, our router IP address is 192.168.1.1. NOTE: If you?re using Windows 98 or ME, click here. Windows 2000/XP Step 1: Click Start, then Run. Step 2: When the Run window opens, type ?cmd? in the Open field, then click OK. Step 3: When the MS DOS Prompt appears, type ?ping 192.168.1.1? and press [Enter]. Step 4: Check the ping statistics. You should get Packets: Sent =4, Received =4, Lost = 0 (0% loss). NOTE: If you?re not getting good replies from the router, it means the router is not communicating properly with the computer anymore. You can already consider the device defective. Windows 98/ME Step 1: Click Start, then Run. A window similar to Step 2 will appear. Step 2: When the Run window appears, type ?command? in the Open field, then click OK. Step 3: When the MS DOS Prompt appears, type ?ping 192.168.1.1? and press [Enter]. Step 4: Check the ping statistics. You should get Packets: Sent =4, Received =4, Lost = 0 (0% loss). NOTE: If you?re not getting good replies from the router, it means the router is not communicating properly with the computer anymore. You can already consider the device defective. If you get good responses from the router, access the router?s web-based setup page to see if a firmware update is possible. For instructions, follow the steps below. Accessing the Router?s Web-based Setup Page In order to perform a firmware update, you should be able to access the router?s web-based setup page. Updating the firmware is one way of resolving the blinking power light on the Linksys router. To access the router?s web-based setup page, click here. NOTE: If you?re having difficulties accessing the router?s web-based setup page, the router is considered defective. If you?re able to access the router?s web-based setup page, proceed in updating the firmware upgrade.

Sounds to me that you dont have a router, you have a hub. If its a real router it would be assigning IP addresses to each computer. Sounds as if you are assigned the same IP to each computer (possibly). Make sure you have your computer set to dynamic IP not static. Instructions here. Other possible issue is the router is set not to manage IP in that case you need to access the router and change it to manage IP. To figure this out Google the make and model of your router to find manual.

Just to verify its an IP issue, turn off the computer that has access and reboot the other one and see if the one your rebooted gets a connection then. If so its a IP issue, if not check the cable connection and drivers for the NIC.

When you connected your PC directly to the modem, were you able to get the internet working automatically or did you have to run a dialup-like connection?

If it worked automatically, try this:
1. Connect a PC to a numbered port of the Dlink router (don't connect the modem to the router nor the PC)
2. Open Internet Explorer and enter http://192.168.0.1 on the address bar. This should then ask you to login. (restart the router and the PC if nothing happened then try again)
3. Enter admin for the username and blank for the password
4. Once you're on the Dlink Setup page, click on Network Settings on the left panel.
5. Change the Router IP address to 192.168.2.1 then hit Save Settings
6. Now, connect a cable from the Speedstream modem to the WAN port of the Dlink router then check if your internet is working from the wired PC.

If its still not working, turn off the modem and the router and then power the modem first (wait for the lights to be stable) then plug the router.

Hope this works for you. Goodluck!

disabling WEP security is not a great idea, unless you plan on replacing it with WPA. As for your request, please open a Browser and enter 182.168.1.1 into your address bar and hit enter. I can't seem to recall exactly where the setting is, but you will come across it if you look through the router admin page. Hope this helps.

First you will need to open up your internet browser (Internet Explorer/Netscape) and go to http://192.168.1.1. You will be prompted for a username and password. By default there is no username and the password is admin. Once you arrive at the routers setup page click on the Advanced tab. Once the page finishes loading, you'll find you will be on the "Filters" tab. Look down and make sure that there are no numbers other than 0 in the boxes on that page. If there are, then you will need to replace them with 0's and click Apply, then Continue. Once you've done that, you're going to want to look for Dynamic Routing at the top, and then click on it. Once that page finishes loading, make sure that the "Working Mode" is set to Gateway, not ?Router?, and that tx and rx are set to Disable not RIP-1 or RIP-2. If a static IP address has been set on the computer, verify the gateways matches the Router's LAN IP Address. If there aren't any installed gateways, add the Router's LAN IP Address. When setting static IP Addresses, you must also input the DNS servers. For more information on assigning static IP addresses, please see the related article on assigning static IP addresses.
