What is UPnP?
UPnP is an acronym for Universal Plug & Play. It is a collection of protocols that allow seamless connectivity and communication between different devices in the same network. It’s easy to use, does not require drivers and can be used with all types of connections and devices.
It can be used with Wi-Fi and Bluetooth as well as Firewire and InfraRed. It will work with any modern media that uses Internet Protocol. This flexibility and ease make UPnP a popular choice for SOHO applications (Small Office/Home Office).
Why do People Enable UPnP?
The primary reason that people enable UPnP on routers is for connectivity and ease-of-use. Mobile phones, tablets, smart TVs and other smart household devices can connect to the network via this feature. These devices can be connected to the home network so they can find each other and collaborate.
Gaming is another reason people want to enable UP&P on routers. For gaming consoles such as the PlayStation or Xbox, NAT type must be set to open/moderate in order to establish a connection to their game server. This is possible by automatically activating UPnP.

UPnP does not require authentication and thus presents a serious security risk. This is exactly why some AT&T routers do not support UPnP.
Is your AT&T router capable of supporting UPnP?
AT&T is both a phone company as well as an ISP (Internet Service Provider). AT&T provides internet services via phone lines (DSL) and fiber optic cables. You’re lucky if you have internet through a phone line. You can activate UPnP on your router if it supports it. AT&T does not allow this feature for fiber optic customers due to security concerns.
Don’t despair if you fall into this category. You can still make it work with a few key things.
We’ll show you how to skip to the fiber optics section.

Enter cmd into the search box. Right-click in the Command Prompt app and select ” Run As Administrator.” After the app opens, type ” Ipconfig” into the search bar.
The default gateway will have the router’s IP address written next to it. Enter the IP address (it should look something like 192.168.0.1) into your internet browser’s address box and hit Enter.
The login page will open. You will need administrator credentials. The default username and password, as well as your IP address, are printed on the sticker. However, if they have been changed by you or your ISP, simply enter the new ones to gain access to the router’s admin panel.
