Why can't I update my iOS?
If you're having trouble updated your Apple devices to the latest iOS, look here.
Sign into your router’s web-based admin website (usually this is http://192.168.0.1 or http://192.168.1.1 If you are unable to access your routers admin page, please consult the Linksys support site for help. https://www.linksys.com/us/support/)
Find the DNS server settings in your router settings. This is usually in a setup menu. Often you will see two DNS fields (one primary and the other secondary. Your router may vary from the following image.)
Enter in the NetAngel DNS server address in the DNS field in your router.
Save the DNS settings in your router
