No Internet Access, but wired to router

Looking for some help...please! I have been having an issue with a desktop computer I have at home. I can access my router, but I can't get on the internet. I have a laptop, Android and iphone that connect to the router wirelessly and have no issues connecting to the internet, but the desktop won't connect. The desktop is connected to the router with an ethernet cable. My desktop is a Dell, Pentium (R) 4 CPU 3.00Ghz, Windows XP Media Center Edition SP3. It is connected to a Linksys Wireless-N Gigabit router. I'm not a computer expert, so I need baby steps. I've looked around the internet quite a bit, but haven't found my exact issue. I've typed in ipconfig /all and this is what I have listed:

WINDOWS IP CONFIGURATION
Host Name RublesDell
Primary Dns Suffix (nothing here)
Node Type Hybrid
IP Routing Enabled No
WINS Proxy Enabled No
DNS Suffix Search List vincinaa.cinergymetronet.net

ETHERNET ADAPTER LOCAL AREA CONTROLLER
Connection-specific DNS Suffix (nothing here)
Description Intel(R) PRO/100 VE Network Connection
Physical Address 00-13-20-93-7E-FD
Dhcp Enabled No
IP Address 169.254.236.85
Subnet Mask 255.255.255.0
Default Gateway 192.168.1.1
DNS Servers 216.135.0.10
216.135.1.10

I manually entered the Default Gateway and DNS Servers because they were missing and I just copied what was on my laptop.
When I try to ipconfig /renew, everything turns to blanks or 0.0.0.0

Any help is very much appreciated!

 

The IP address you have (169.254.236.85) is not a good IP address for your network. XP provides this IP address when one is not received from a DHCP server, in your case your router. One interesting thing to me is that your laptop has a DNS other than the router gateway address of 192.168.1.1.

Questions:

Do the machines that work have static IP addresses, or do they get their IP addresses automatically? Go to a working XP machine and go to CONTROL PANEL > NETWORK CONNECTIONS. Right click on your LAN connection and click PROPERTIES. Click on INTERNET PROTOCOL TCP/IP and click PROPERTIES. Do your settings match what I have attached? If not, please report what they are.

 

The other machines have automatic IP addressing. The desktop used to, but when the internet quit working I did a ipconfig /release and ipconfig /renew, but the address was 0.0.0.0. At some point, it changed to 169.254.236.85. With that address, it seems to connect to the router, but not the internet.

 

That address will not work. I suspect that there is something wrong with the driver, but first lets try something. Configure your connection with static IP address of 192.168.1.250, gateway of 192.168.1.1 and a DNS of 216.135.0.10.

Let's see how that works.

 

I changed the addresses as you advised. I seem to still be able to connect to the router, just not the internet. My LAN on "Network Connections" shows "Connected, Firewalled". I have some software called "Linksys Easylink Advisor" that came with the router. I can connect to the router and see all the devices that are connected to it (wired or wireless) and their IP addresses. Just the desktop won't connect to the internet, the others do.

 

Pretty much what I expected. Do you have the drivers for the network card? Have you tried changing the cable?

When you go tO NETWORK CONNECTIONS what kind of network card is in the machine?

 

Can you ping 192.168.1.1?????
Can you ping www.complete-cs.com?

 

No, I cannot ping 192.168.1.1. I thought I was connecting to the router, but if I can't ping it, I assume I'm not connecting. Pinging www.complete-cs.com doesn't work either. 4 packets sent and 4 packets lost.
I have an Intel PRO/100 VE Network Connection card (if I'm reading this right, I found it under the Local Area Connection Properties "General" tab. Under "Connect using"). I went on Intel's site with my laptop and downloaded the latest driver version. I installed it on the desktop, but I still can't access the internet.
I haven't tried another cable. I'll have to find one.

 

Very good. Try the cable first. If that doesn't work go to device manager and delete the PRO/100 network card. Reboot the machine and let windows reinstall the network card drivers and rebuild TCP/IP. If windows can' t find the driver, reinstall it manually from the file you downloaded.

 

Sorry for the delay....I had to go to a wedding. I picked up 2 new ethernet cables at my workplace. No luck yet. I removed the network drivers and restarted my computer. By defualt, the "obtain an IP address automatically" and "obtain DNS server address automatically" is selected. Initially, the IP address and subnet mask were 0.0.0.0. After a couple of minutes, the IP address changed to 169.254.117.80 and the subnet mask changed to 255.255.0.0. Shows "limited or no connectivity". Default Gateway, DNS server and WINS server are all blank.
I manually changed the IP address to 192.168.1.250, subnet mask to 255.255.255.0, default gateway to 192.168.1.1, and DNS server to 216.135.0.10. Now it says "connected, firewalled" but still can't connect to the internet. Tried to pind 192.168.1.1, but showed "request timed out" all 4 times. I can ping 192.168.1.250 and the response is OK. 4 sent, 4 received.

 

Interesting. Take one of the other machines with its wireless disabled and connect it to the router with a wire. Lets make sure the router's wired ports are working correctly.

Again, the 169.254.117.80 IP address means that the machine CAN NOT get an IP address from the router.

You may also want to turn off the windows firwall.

 

OK, I took my laptop, turned off the Wifi and plugged the cable into it from the router. The laptop instantly picked up the signal and attached to the "Local Area Connection". So it appears the router and the cable are OK. I don't know what the DNS server number does, but the number I entered in the desktop is just a number I copied off the laptop. Is that a problem or not?

 

Very good. Copying the DNS address from the laptop is no problem. Generally when an IP address is obtained from the router the DNS is the routers IP address. In your case it would be (192.168.1.1). Either way will work.

We are running out of options. Can you turn off the firewall and give it a go?

 

I turned off the firewall and restarted the desktop. I typed in ipconfig /all and saw that all the settings were still the same, so that was good. Still can't get on the internet and tried to ping 192.168.1.1 with no luck. Could this be a hardware issue? This Dell desktop does not have a LAN "card", it's built into the mother board. Should I buy a PCI LAN card and install it? If so, how would I disable the current systme on the motherboard?

 

Installing a new network card would be my next suggestion.
