wireless network connection does not have valid ip configuration

    Question

  • I've tried lot's of things.

    I've tried uninstalling and reinstalling network adapters. When I restart my computer after I've tried to uninstall, I can't reinstall because the adapters are already there.

    I've tried resetting TCP/IPv4... whatever that means. But nothing happens.

    I don't know what to do.

    Also, I'm unable to do system restores.

  • Other than not having a valid IP configuration, are you able to connect to the net or get a valid IP if you're connecting through ethernet cable? Care to share how you connect through wireless? Is it through a router & modem?

  • Well, the problems STARTED when I tried connecting to a modem via ethernet cable to Comcast's Xfinity. I couldn't connect to that internet either, but Comcast thought it was a problem with the cables, not my computer. I thought so too because up until that point, I'd been able to connect to the public library's wifi.

    I have no other way to check to see if I can connect to the internet via an ethernet cable.

    I don't know how the wifi at the library or my office works. I think it's through a router or modem, but I can't be sure which.

    Hi,


    Please check whether you could connect Internet in other network environment to determine the root cause.
