Comcast vs Fiber

I recently hooked up internet in a location without Fiber and had to go to Comcast. It’s the first time I’ve used their service since I was in high school so I was hoping it had improved.

Surprisingly they said I could get 20 Mbit fiber which was awesome. My fiber was only 15 Mbit. So I got everything setup and quickly ran a speed test

Comcast 20/5

Advertised: 20/5
Actual: 5/2

Strangely I only got 5 Mbit. I thought it might be the server so I hoped on my old fiber connection and ran the same test:

BroadWeave 15/15

Advertised: 15/15
Actual: 13/10

Traffic Shaping

I was disappointed by the big loss of speed from Comcast. I expected them to fall short of advertised (everyone does) but to fall all the way down to 5? I lost 75% of my speed while fiber sat around 15% loss. That’s awful but at least I should be able to stream video.

I connected to my file server which is where I store my legally obtained digital content and started streaming. Uh-oh, even though the server can pump out 1500 KB/s I can only get 125 KB/s when going through Comcast. I checked from a few other locations and got stellar speeds which means Comcast is traffic shaping. Other locations give me quite a bit better speed, in the 1500 KB/s range but when I hit my server all of the sudden traffic shaping kicks in and my speed tanks.

Monopoly

Enjoy your monopoly now Comcast, or should I say Xfinity, because as soon as anyone has choice it will quickly become apparent that your internet offering is subpar. I don’t need a company deciding what traffic of mine is worth my bandwidth, that’s my business. Further, I think I ought to make a complaint to the BBB about your outrageous speed discrepancies.

I was apparently the first person in Salt Lake City to sign up for Comcast's last mile fiber 50Mbps connection. It cost twice as much as what I had on Utopia and only offered a fraction of the upload speed. The most I could pull out of it was 25Mbps so I called Comcast and asked what was up. About 5 technicians, including the guy who designed the network for SLC came out to my house to try to figure it out. After a day of tinkering they finally threw their arms up and said "I guess we weren't ready to roll this out."

Now I get decent speeds on and off, but some things are constantly giving me trouble. Pulling content from the server, for example, and youtube for some reason. Comcast SUCKS at youtube and it often takes 30 or more minutes to buffer a 2 minute video. Pulling it up through a proxy results in no problems. They deny they are traffic shaping, and I'm inclined to believe them, I just think they actually suck that bad.

absolutely. You should be on the phone with Comcast getting them to come fix it (not now, obviously...it's 5:19am). Absolutely submit to the BBB if they can't fix. That's serious junk. I have Comcast, and I get very close to advertised, but it's 6/2.
