In order to demonstrate a product connected to my wireless router I need to set up a static IP address so that I can "see" - log onto - the product from anywhere on the internet and from a table or a smart phone.
How can I set up a static IP address for my wireless router? Router is a Asus RT-AC68U.
In order to access your network from anywhere on the Internet, your external address needs to be static. For the most part, this isn't too much of an issue as your ISP usually does not change your external IP address that often. However, if you need to be able to connect regardless of whether your external IP Address has changed, you need to find a free DNS service that maintains updates to your external IP Address.
Of course, an easier option would be to upgrade your service through your ISP to a static (usually business) IP Address.
