Win 7 Netbook Wifi gone and won't come back.....

Ok so some progress.

Following some info from these posts
Unable to connect to adhoc wireless networks :(
and this
How do I block a disruptive, unwanted wireless signal in Windows - Microsoft Community

I entered the command netsh wlan show filter
and then the command

netsh wlan set blockednetworks display=show

And now I find that I can see wifi networks although they are all prevented from connection due to the following error
"Your network administrator has blocked you from connecting to this network"

Ok so not much of an update but here is where I am at.

I have been able to have the wifi show networks in my area including my own,
I am able to connect to my network.

However......

I have limited access and cannot access the internet. I have a yellow exclamation against the wifi icon.

Looking at some of the troubleshooting details it doesn't appear that I am getting an IP address.

Any thoughts?

Yes wired not working now either.... (sent via Linux)

Its now the same for the wired as it is for the wireless, limited access and no Internet access.
