    My Dell Inspiron laptop running Windows 8.1 will no longer connect to our home network, and diagnostics produce the error "Wi-Fi doesn't have a valid IP configuration". All our other devices are able to communicate with the network and my laptop will communicate with it if booted using ubuntu, so it appears to be a Windows issue.

    I have: rebooted the router, performed a clean boot of the laptop, reset winsock and TCP/IP using netsh, set the laptop to not turn off anything in an effort to save power, released and renewed the laptop's ip address, manually assigned an ip address to the laptop and checked to see if Bonjour was installed (someone posted that removing it fixed their problem, but it already wasn't installed on my computer). Have you run into this before, or do you see something "obviously" wrong with the configuration results below?

    Thanks,
    Laura

    Resetting all firewall properties on the laptop to their default values solved the problem. Obviously there are many possible causes, but hope this post helps someone else solve their issue.
