Your Internet 2go Service Performance
Comcast provides the Internet 2go service (the "Service") using state-of-the-art networks that are operated and managed by third parties that Comcast works with to provide access to the Service and to deliver the best possible mobile Internet experience to all customers. In light of the particular technical and operational circumstances regarding mobile wireless networks, however, no mobile wireless Internet Service Provider ("ISP") can guarantee a particular speed at all times to a customer. The "actual" speed that a customer will experience while using the Service depends upon a variety of conditions and factors, many of which are beyond Comcast’s control. These conditions include:
- Performance of a customer's computer, including its age, processing capability, operating system, the number of applications running simultaneously, and the presence of any adware and viruses.
- Coverage and network signal quality, which can be affected by any number of factors outside the control of the network operator. For example, factors such as terrain and foliage, weather conditions, the presence and composition of buildings and other man-made objects, and the number of users simultaneously trying to connect to the network all can affect the performance that customers may experience at any moment in time.
- The distance packets travel (round trip time of packets) between a customer's computer and their final destination on the Internet, including the number and quality of the networks of various operators in the transmission path. The Internet is a "network of networks." A customer's Internet traffic may traverse the networks of multiple providers before reaching its destination, and the limitations of those networks will most likely affect the overall speed of that Internet connection.
- Congestion or high usage levels at the website or destination. When you access a site or particular destination that is being visited by others at the same time, you may experience a slower connection if the site or destination does not have sufficient capacity to serve all of the visitors efficiently at the same time.
- Gating of speeds or access by the website or destination. To control traffic or performance, many websites limit the speeds at which a visitor can download from their site. Those limitations will carry through to a customer's connection.
- The performance of the mobile broadband device you are using. Comcast provides you with the mobile broadband device to use with the service, but, like all electronic devices, this device is susceptible to degradation over time caused by any number of factors outside of Comcast's control. If the device is not working at its optimal levels, you may not experience the highest-quality performance.
Specific Speed and Latency Information
Service speed is one of the means by which customers and providers alike measure the performance of a broadband Internet connection. As discussed above, however, any number of factors can affect the speed of the service. Because third-party providers, not Comcast, operate and manage the Internet 2go networks, Comcast does not presently have accurate and reliable speed test data for the Internet 2go service. Comcast will update this section and post the speed test data from the third parties that operate and manage the Internet 2go network when that data becomes available to Comcast. However, you can test your speeds yourself. Comcast offers its customers the ability to test the speeds that they are receiving on Comcast's network – from the customer's computer to test sites located throughout Comcast's network. Simply go to http://speedtest.comcast.net to test your connection. These tests are heavily dependent on many of the factors outlined above, however, and therefore do not necessarily reflect the performance of the Internet 2go networks.
There are other speed tests that measure Internet performance. We have provided links to a few of these sites below for your reference. Please note, however, that all speed tests have biases and flaws. Each of these tests measures limited aspects of an ISP's speed and therefore must be seen as a guide rather than definitive measurements of performance.
Latency is another measurement of Internet performance. Latency is the time delay in transmitting or receiving packets on a network. Latency is primarily a function of the distance between two points of transmission, but also can be affected by the number and quality of the network or networks used in transmission. Latency is typically measured in milliseconds, and generally has no significant impact on typical everyday Internet usage such as reading an email, viewing a webpage, or downloading photos. As latency varies based on any number of factors, most importantly the distance between a customer's computer and the ultimate Internet destination, it is not possible to provide customers with a single figure that will define latency as part of a user experience. Because third-party providers, not Comcast, operate and manage the Internet 2go networks, Comcast does not presently have accurate and reliable latency data for the Internet 2go service. Comcast will update this section and post the latency data from the third parties that operate and manage the Internet 2go network when that data becomes available to Comcast.
When You're Roaming
From time to time, when you are outside the Internet 2go coverage area or otherwise unable to get a signal from the Service, you may be able to "roam" on another provider’s network. Regardless of whether you are roaming or using the Comcast Internet 2go networks, many of the above-mentioned factors will affect the performance of the service. However, when you are roaming, Comcast has no control over the level of performance of the service you are receiving.
