How To Enable UPnP On Spectrum Router?

The UPnP (Universal Plug and Play) protocol is enabled by default on most routers. However, UPnP is somewhat dangerous when it comes to security, and that’s why it’s disabled by default on many Spectrum routers.

It can also be very useful when you want to integrate a new device into your network without the extra configuration. So, this article covers what UPnP is, how to enable UPnP on Spectrum Routers, and other useful information regarding the topic.

How To Enable UPnP On Spectrum Router

What Is UPnP?

Plug and play technology allows us to connect a gadget to our devices, such as a USB mouse or keyboard, and immediately use it. The UPnP is an extension of plug and play, and it’s a group of protocols that helps residential and small business networks.

Once you connect any device such as a printer, scanner, or something similar, the UPnP allows the device to create a working configuration to connect to all other devices. That’s the beauty of UPnP, but it’s also something that makes it insecure. So, how does it work?

How Does UPnP Work?

The UPnP uses a group of protocols that our devices normally use to connect, stay connected, and transfer data over the network. So, the UPnP automatically provides the ID data to the device connected to a network.

This means that the device gets an IP address, and it’s now visible to the rest of the network, but we also see what the device does, if it’s a printer, an IP camera, a scanner, etc. It also gives us control over the device, e.g. record a video, stop recording, pause, etc. So, it gives us ease of access to our devices. This is why we might want to enable it, and let’s see how.
