"We've built HSI from the ground up to make it easy, fast, and most of all helpful for you. It's our goal to make sure you get the best internet service, wherever you are." - Tanner Christensen, HSI Strategist
Serving high speed Internet customers in 39 states, Comcast Corporation offers broadband connectivity through its cable infrastructure. Because Xfinity already has existing cable lines into many residences and businesses, all the consumer needs to do is to purchase or lease the cable modem; the company offers the consumer the option of a Do-It-Yourself kit for the home installation or sends a trained technician do the work.
Connections speeds vary, with downloading or downstream (from the Internet to the consumer's computer) speeds being faster, typically, than the uploading or upstream (from the user's computer to the Internet) speeds. Xfinity offers PowerBoost® which provides bursts of speed in the initial connection. Like most high speed Internet providers, Xfinity has multiple speed / pricing tiers available for the consumer, so that the consumer can determine which is best for his or her needs.
Performance Tier – With this tier, the maximum download speed is 12 megabits per second (Mbps) and the upload speed tops out at 2 Mbps. Using PowerBoost®, those speeds are up to 15 Mbps for upload and 3 Mbps for download.
Blast! ® Tier – Downloads speeds up to 20 Mbps with PowerBoost®. It has super fast speeds so you can download TV shows, stream HD movies, and more.
Compare your Internet speed to the tiers offered by Xfinity using our Internet speed test.

May 17, 2012Great for gaming and solid upload/download speeds
"I have had DSL and Cable internet and cable clearly is the choice if you want a reliable download speed. I consistently pull 15+mbps down and 6+mbps up. We don't have the option of fiber optics in Salt Lake City. But the price of cable is hard to beat for the speed. "

April 26, 2012Comcast is pretty good
"All in all, Comcast is pretty good. We have digital cable and phone via Comcast as well and we have less complaints than Verizon users seem to have. It can be expensive, but so is Verizon."
Disappointing

"Comcast's speed is OK, unless its the evening or the weekend and then its really lagging. For the price its pretty bad. They are the only internet provider in our area so there isn't much else available. If you have the option to get them and someone else, pick someone else!"

April 25, 2012Comcast. The best Internet Service Provider
"I have Comcast , wich i think is great because the speed , the service and price are so accesibile for everyone. I am very happy with this company. One more thing, if you have trouble with your internet they can fix it right away by phone or sending someone real quick. Thank you Comcast."

April 25, 2012My experience with Comcast
"I really like my internet provider. The speed is really fast since its cable internet and not DSL. They also have really good customer service. The man who set up the internet did it really fast and was done within an hour. They are also reasonably priced too. I think I will recommend them to my family and friends who are looking into changing service providers. Hopefully they will choose Comcast. The only problem though that I have found with them is that sometimes the internet cuts out, but that really isn't a very big deal since it can be fixed quite easily."

April 24, 2012Overall Ok
"I am for the most part pretty happy with the service we receive from Comcast but I really do feel that we don't get what we pay for. The prices are really high. We do get some outages and speed drops which makes streaming tough at times but not for long. I have considered switching but only to find they have a monopoly on my area so there are no other options. Customer service is pretty great though, they have helped troubleshoot problems that aren't even related to their service or equipment. Like I said, the prices could/should be better."
So, so

"Comcast is generally fast and reliable. I had one problem where some lines went down and comcast came out within 24 hours and repaired the problem. It's a little pricey, but worth it to have 25+ Mbps."
Not Good

April 21, 2012Not Worth It
"The service is pretty dicey and it costs much more than it is worth. Every once in a while I have a problem so bad that someone has to come out and repair things."
Great

April 20, 2012Fast, but...
"The service we upgraded to is incredibly fast. I think we're doing 30MB/s now. The only problem was that with the basic package, during peak hours, the internet would get very slow. The pricing is average for our area. Have only had one outage in almost a year."
Good

April 20, 2012Great Interent
"I've never had any real problems with my service from Comcast. It's gone out twice in the last 3 years, but only for a couple hours and they fix it right away. And every time I've called, they give me a window when the problem will be fixed and it's usually faster than they predict. It's a little pricey, but the speeds I get are great and Comcast is easy to deal with."
