I recieved a couple of windows updates yesterday and have been unable to connect to wifi ever since. I have tried system restore, and removing the network drivers and reinstalling them but no luck. This happened before and if I recall correctly I had to go into regedit and change something. I cannot find the post on the forum where that correction was a vailable? Anythought on what might be up here.

No wifi showing in network sharing and is not even an option.
Your LAN adapter is also showing disconnected, are both wired and wireless affected?
Please try the following suggestions:Ethernet adapter Local Area Connection:
Media State . . . . . . . . . . . : Media disconnected
If it's just a wireless issue and you're using a laptop or Netbook, look for a physical wireless switch or button if it's ON or OFF.
Check your computer's Bios setting, navigate around and try to locate the integrated ethernet controller and make sure that ethernet controllers (also Wi-Fi) is/are enabled.
How to enter the BIOS or CMOS setup.
Click on Start and right click Computer, choose Manage, go to Device Manager, expand network adapters, do you see your Network adapters?
Also, Temporarily disable Norton for now and see if this helps. Enable it back after the debugging process.
Please repeat and post another ipconfig /all output on your next post. Your initial output was missing /all.

So the wifi switch is on as it controls my bluetooth as well and that is working. In the BIOS it shows the ethernet controls as enabled. Yes the ntetwork adapters show up in the device manager. This has happened before and the reinstalling of the original network driver usually fixed it. I am traveling and do not have access to a lan connection but seeing as it actually shows up as an option in the network and sharing centre (wife does not) and has always worked in the past in this situation I have to assume this would be the case again.
The last time I did this was a couple of years ago and it finally took changing something in regedit to solve the problem.

Thanks for the output, it is correct this time.
I'd suggest for you to uninstall Norton for now by using this Removal Tool, this 'might' be the culprit. You may reinstall it back if you wish as soon as your issue has been resolved or replace Norton with other great free software such as MSE, AVG, Avast or Panda Cloud Anti Virus.
Please test your connection after and another update of your progress will be nice.Norton 2012 is the security software
So Norton is uninstalled and still no wifi. I have contacted Panasonic and they tell me it is windows issue.
Next tasks to do:
Run sfc/scannow:
Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
Brink's Tutorial on how to run chkdsk:
Disk Check
So I ran system file checker and there were no integrity violations. Ran scan disk and that also had no issues arise. Still no wifi.
I reset the bios to default and that had no effect either.
Next tasks:
Click on Start=> All Programs => Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.
Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log press enter
Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log press enter
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog press enter
Restart the computer after.
From the troublesome computer verify that all your network services are Started from Control Panel=> Admin Tools=> Services:
• 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
• WLAN AutoConfig ( Vista wireless configurations only)
• Workstation
Let's pause here for now and please report back.
