  1. We would need your computer specs to be able to help.
  2. it cannot connect to the router, giving you that default ipv4 address. using software will not help. make sure that its ethernet/wireless is working, and if it isn't, update the drivers from device manager(download new driver on other pc, transfer file, right click computer, manage, device manager, right click device, etc.)

    If it is working, get it connected, then open command prompt. type "ipconfig /release", hit enter, wait, then type "ipconfig /renew" and hit enter. this is to retrieve new info from the router.

    if it doesn't work, you might have a problem with your router, like only being able to connect "x" devices at a time.
  3. Download Reset TCP/IP
