wifi doesn’t have a valid ip configuration (Limited)

Hi,

I have a relatively new HP Envy (H8-1485ea), with no modifications made, running windows 8. I have had the been using it with a wired connection at university with no problems and on return home connected wirelessly. Initially I encountered no issues, however after about 2 days the status of the connection went to limited and has remained that way since.

On running the windows troubleshooter it stated that the “wifi doesn’t have a valid ip configuration”.

I searched this forum and found the suggestion to run the commands which resolved similar problems:
netsh winsock reset catalog
netsh int ip reset rest.log hit

However as shown in the attached image for the second command resetting failed. I am not sure if this is where I am going wrong or if there is another issue.

I have also attached my ip configuration.

Any suggestions on how to resolve this problem would be much appreciated, Thanks.
