Exclamation ipv4 & ipv6 not connected - no internet connection
All of a sudden I cannot connect to the internet on my laptop using the ethernet or wireless. My desktop computer is fine.

It says that there is no connection on ipv4 and ipv6 and that my connection is limited (even though there is no connection.

I have followed everything I could in the following thread with no improvements.

http://forums.techguy.org/networking...ss-but-no.html

I am on Vista and have had no problems with connectivity until today.

Is there any way someone could help me? Thanks.

We need to have information on make and models of all your the equipment please.

PC/Laptop
Router/Modem
Who is the ISP (Internet Service Provider)
The desktop machines that is working - is that cable or wireless ?

-> firewall blocking - what firewall / secruity program do you have ?
-> wireless Encryption - Remove any wireless encryption from the router, and try to connect - post back results

You will nedd to save these and copy onto the desktop - using a thumbdrive or CD-rw
{ipconfig /all}
We would like to see the results from ipconfig /all

-> Start > run {search bar in Vista} > cmd > ipconfig /all
post back the results here


TWO Methods to do that - if you cannot access the internet with PC, then use method 2 to copy onto a machine that can access the internet and post results here

Method ONE -------------------------------------------------------------
start > run {search bar in Vista} > cmd > ipconfig /all

rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Method TWO -------------------------------------------------------------

Start> Run {search bar in Vista}> CMD to open a DOS window and type:

IPCONFIG /ALL >C:\RESULT.TXT

Open C:\RESULT.TXT with Notepad and copy/paste the entire results here.

----------------------------------------------------------------------------

{Ping Tests}
Start> Run {search bar in Vista}> CMD to open a DOS window and type:

Ping the default gateway shown in above ipconfig /all
Post back the results

Ping google.com
Post back the results

rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Ping 209.191.93.53
post back results

----------------------------------------------------------------------------

{Device Manager}
Post back the results in device manager
Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} > network adaptors, click on the + > post back the devices listed there
are there any ! ? or X
----------------------------------------------------------------------------
----------------------------------------------------------------------------
Download, copy to PC and install
http://www.xirrus.com/library/wifitools.php

Then run the program and post a screen shot of the program running
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.

You have no network hardware that is recognized by Windows Networking.


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?

JohnWill -

Thank you for your reply. I attached a screenshot of my network adapters above. Why would the network hardware stop being recognized all of a sudden?

strange the wireless tool can see the wireless signal and so can the adapter but not connect

a few ideas

(From a JohnWill post)

TCP/IP stack repair options for use with Vista.

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

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.

From a Johnwill post

Check your Services are Started on all PCs:
  • COM+ Event System (for WZC issues)
  • Computer Browser
  • DHCP Client
  • DNS Client
  • Network Connections
  • Network Location Awareness
  • Remote Procedure Call (RPC)
  • Server
  • TCP/IP Netbios helper
  • Wireless Zero Configuration (XP wireless configurations only)
  • WLAN AutoConfig (Vista wireless configurations only)
  • 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 (or perhaps manual).

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.

Done

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
This is what I go when trying this command. I even rebooted and tried again with the same result:

Reseting Echo Request, failed.
Access is denied.

There's no user specified settings to be reset.

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
This is what I go when trying this command. I even rebooted and tried again with the same result:

So far no change in connectivity.

After you run the repair suggested by Terry, post another IPCONFIG /ALL again.
