UPDATE 3: Here is the official Comcast information regarding the new speed tiers. Note that, according to the site, PowerBoost has upper limits depending on the speed tier you’re using. Comcast has deployed these limits in some ares, however they aren’t here in Denver yet. When they are, I’ll report/moan/whine/complain about them in typical blogger style.

UPDATE 2: According to other Denver-area folks, the DOCSIS 3 upgrade does not require a truck roll, as I suspected. Just go to your local Comcast store (the closest one to Golden is in Wheat Ridge, 11501 W 44th Ave), make the upgrade and pick up a modem if you want to rent one.

UPDATE: Apparently DOCSIS 3.0 in Golden went mere hours ago (this morning, to be exact). So if Comcast representatives don’t seem to know what they’re talking about yet, try to forgive them; the northern part of the Denver metro doesn’t even have DOCSIS 3 turned on yet. Some places aren’t even on DOCSIS 2.

Also, if you want to get a Motorola SurfBoard 6120 modem to take advantage of DOCSIS 3 speeds (or channel-bonding PowerBoost, which from what I hear works even on lower tiers) they can be had at Amazon for about $93. On the flip side, that’s 29 months worth of modem rental fees, and prices will go down for the modems as time goes on. On the other hand, if you plan on sticking with a non-DOCSIS 3.0 Comcast tier, looking around for a cheap modem could put you out ahead of rental fee costs in under a year.

Finally, for those wondering where Qwest’s service falls in relation to Comcast’s in terms of speed, Comcast trumps both Qwest tiers available here unless you guy the Economy tier on Comcast. On the other hand, Qwest costs less than Comcast when not on promotion…


Sometime in the past couple of days, Comcast has gone live with their DOCSIS 3.0 service in the Denver area, just in time for school. Below are current speed tiers and prices based on what I was able to gather from a Comcast rep online. The two highest-end tiers require a new channel-bonding DOCSIS 3.0 modem like the Motorola SurfBoard 6120 (or you can get whatever Comcast has in stock, which might be a Cisco model instead). According to the representative, upgrades to a DOCSIS 3.0 tier will require a $99 installation charge, though I believe have confirmed this information to be incorrect. New internet installations on the other hand do require this fee if you don’t already have cable TV with the company.

The prices below reflect internet-only service without promotions. If you want to rent a modem from Comcast, add $3 + tax ($3.22 or so) to the monthly price. If you’re on a promotion or are bundling Comcast service with something else, prices will be less. There’s no contract on any of Comcast’s services unless you are buying a “triple play” bundle and don’t want your second-year price to skyrocket. All tiers have Comcast’s 250GB “soft cap”; usage above the cap will get you a warning, then a disconnection for one year. Comcast also has traffic management software in place to throttle down heavy users during peak periods, however the protocol is relatively benign.

  1. Economy – 1 Mbps down / 384 Kbps up – $34.95
    No PowerBoost, not heavily advertised
  2. Performance – 12 Mbps down / 2 Mbps up – $54.95
    PowerBoost, probably the best value for your money, default tier
  3. Blast! – 16 Mbps down / 2 Mbps up – $64.95
    PowerBoost, highest-speed non-DOCSIS 3.0 tier
  4. Ultra – 22 Mbps down / 5 Mbps up – $74.95
    DOCSIS 3.0, PowerBoost, best tier for power users in my opinion
  5. Extreme – 50 Mbps down / 10 Mbps up – $116.95
    DOCSIS 3.0, no PowerBoost, fastest tier, faster downloads than Qwest VDSL2

If you’re wondering whether Ultra could conceivably outpace Extreme while PowerBoost is active, the answer is a resounding “yes.” In fact, in most cases the Performance tier can match or exceed Ultra’s “regular” speeds while on PowerBoost; due to DOCSIS 2.0-sized upload channels (a must-have for DOCSIS 3) PowerBoosted upload speeds for every tier but Economy will many times reach 9, 10 or even 11 Mbps. That said, for longer downloads and uploads PowerBoost will wear off and you’ll get the speeds you pay for.

One final note: promotions are easy to get; just ask for them. I’m locked in for six months at a rate roughly $23 below Comcast’s regular structure simply because I walked into the omcast store and hinted at downgrading due to my then-$65 internet bill. That said, I had been paying full price for a few months prior to the office visit, and I’ve now been using the company’s internet service for a year or so.
