UPnP Setup

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers access your network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on your network. 

  1. Log into the router. Click here for instructions
  2. Click the Advanced tab
  3. Click Advanced Setup
  4. Click UPnP

Select UPnP

  1. Select the Turn UPnP On checkbox
  2. Set your Advertisement Period and Time to Live preferences

Advertisement Period – The advertisement period is how often the router broadcasts its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations can compromise the freshness of the device status, but can significantly reduce network traffic.

Advertisement Time to Live – The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it might be necessary to increase this value.

  1. Click Apply to save your settings

Turn UPnP On

The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the router and which ports (internal and external) that device has opened. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address.

Charter does not provide technical support for the Universal Plug and Play (UPnP) feature of the router used by some Charter WiFi customers.

While Charter is able to support most advanced features of this router, the foregoing feature may require that you establish an individual relationship with vendors such as Netgear or dyndns.org, or require the use of a customer owned third-party device.  As a result, Charter does not have the visibility necessary to assist with setup or support for this service.  You may visit the vendor's websites for more information on setting up or troubleshooting this service.  Please be advised that these vendors may charge for support for this feature.
