  1. You should be able to change your computer network settings to obtain an IP address -- go into your network settings control panel, change adapter settings, select Internet Protocol v4 and double left click, set it to obtain network address automatically and DNS automatically. Then you may need to open the command prompt window and type ipconfig /release and then ipconfig /renew.
