Laptop has been connecting to internet for years. Originally using wireless Linksys router but wireless card in laptop stopped working. Have been connecting via Ethernet connection for over a year. All of a sudden, cannot connect to internet via Ethernet connection. Laptop connects fine using wireless mobile card (Verizon) with 75.x.x.x address.

Using same Ethernet connection, another laptop connects fine (69.x.x.x address)

Network status on "broken" laptop shows "Unidentified Network Access: Local Only

Ethernet adapter has 169.x.x.x address when connected to cable modem (Roadrunner) with no default gateway.

Tried to release/renew IP but get message "The requested operation requires elevation." I am running under admin account.

More info -- cmd from Gateway that won't connect.
Remembered how to Run as Admin for the ipconfig /release and ipconfig /renew commands.
Received "No operation can be performed on Local Area Connection* 15 while it has its media disconnected."

Checked network adapter status - 6TO4 Adapter has yellow triangle with !.
The Ethernet and Wireless adapters say they are running correctly.

Let's do the easy thing first.
Check for stack corruption.
Stack repair for XP and Vista.
Courtesy of Johnwill of the Networking forum.

TCP/IP stack repair options for use with Windows Vista.

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

And make sure all our I's are dotted and T's are crossed.
From a Johnwill postConfigure DHCP for Windows Vista.
1. Click on the Start menu, and select Control Panel.
2. Click on Network and Internet. (Skip this step if you do not see this Control Panel item.)
3. Click on Network and Sharing Center.
4. Click on Manage network connections.
5. Right click on Local Area Connection and choose Properties. If Windows say it needs your permission to continue, click Continue.
6. Select Internet Protocol Version 4(TCP/IPv4) and click Properties.
7. Select Obtain an IP address automatically.
8. Select Obtain DNS server address automatically.
9. Click OK to close the TCP/IP Properties window.
10. Click OK to close the Local Area Connection Properties window.
11. Click Close to close the Network Connections window.
12. Click Close to close the Control Panel window.
13. Restart your computer.

Thanks so much for quick response.

I reset as suggested and verified the settings (obtain IP and DNS automatically). Rebooted laptop.

Same status.

[pedroguy]

Just to clarify.Have you used a know working ethernet cable on this connection ?
Is the lan adapter light on ?
And when you direct connected to the modem,did you do a power on reset of the modem ?
Any changes? Hardware/software ?
Then let's see this .
Let’s take a look at the status of the network adapters

Device manager:

Hold the Windows key and press R, then type devmgmt.msc

Please respond to all the following steps.
1. Under Network adapters, please tell me all the devices listed.
2. Are there any devices under Network adapters that have a red x displayed?
3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?
4. should be enabled and working properly.
5. If error code,what is it ?

It would be best if you could post a screen shot of Device Manager with the Network adapters and Other devices sections expanded.

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.

And another I's dotted task.



Check your Services are Started on all PCs:
• COM+ Event System (for WZC issues)
• Computer Browser (computer browser will start when needed)
• DHCP Client
• DNS Client
• Network Connections
• Network Location Awareness
• Remote Procedure Call (RPC)
• Server
• TCP/IP Netbios helper
• Wireless Zero Configuration (XP wireless configurations)
• WLAN AutoConfig (Vista wireless configurations)
• Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic
If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.

Yes ... I can switch the Ethernet cable to another laptop and connect to the Internet with no problems.
There does not appear to be a light on the LAN port. Device manager says the adapter is working properly.
When I direct connected to the modem, I did power reset the modem.
No hardware or software changes to the laptop or modem since last time it was working .. same modem and cable were working with this laptop previously and work properly with another laptop.

There are no devices with RED X
There is one device with YELLOW ! displayed --6TO4 adapter, driver can't be loaded for this adapter, code 31

Screen shot of Device Manager is attached.

Didn't check logs as all services were started. Please let me know if I should check for errors in the logs.

There does not appear to be a light on the LAN port.

On the computer's port? Indicates ethernet card failure. Some PCs power down the ethernet to save power when it is not being used, so connect the cable before powering on the machine to make sure this is not what's happening.

[kymlord]

I removed the Ethernet cable, powered down the laptop, connected the Ethernet cable and powered up the laptop just to be sure that wasn't the problem. Still the same status.

Regarding the light on the Ethernet port, there isn't a light on the port -- nothing that can light up (or not light up).

On the cable modem, there are the same lights when either of the laptops are connected EXCEPT there is no RECEIVE when the Gateway is connected.
