Docsis 3.0 Cable Modem

Formally the Appleton area, now living in the Wausau area

I was just wondering if anyone is currently using a Docsis 3.0 cable modem with their service right now and if they have notice any changes in performance. Charter just sent me a notice about raising the cable modem lease fee so I decide to go out and just buy a modem instead. I know no one in Wisconsin is offering Docsis 3.0 services right now but I figured some day they will. I have read online about people who have done the same thing and they have seen the performance of their internet service get a bit better. So far it seems like my internet is a bit more snappy on the page loads.

I thought if anyone in

I thought if anyone in Wisconsin might implement DOCSIS 3.0, it'd be the lakeshore footprint of Comcast, because I thought they were starting to deploy it in other areas. Hard to tell what's in Time Warner's crystal ball these days, though I did see a page on their website talking about Road Runner Mobile coming soon (WiMAX?). Since they consolidated their websites nationwide, it's hard to tell what's local and what's not.

I know Comcast is in

I know Comcast is in Manitowoc. Not sure how much of the surrounding area they cover because Two Rivers is Charter. Last I had heard Comcast planned on having 20% of their territory in 2008 and between 65-80% in 2009. They were supposed to have 50% of their territory cover already in the first half of this year. I would imagine with the Wisconsin territory being so small they will be one of the last areas to go Docsis 3.0.

I know Time Warner has just begun to roll out Docsis 3.0 but I believe they are not in a rush with it and they are only concentrating on areas with competition from Verizon FIOS like NYC.

As for Charter which is dealing with bankruptcy, they were starting to deploy Docsis 3.0 late 2008/early 2009 in areas with competition from Verizon FIOS but I haven't heard anything lately. I guess the competition from Verizon in about 40% of their territory.

I know TDS recently launched a 50/20 Mbps fiber service in Monticello, Minnesota for $50. That was in response to the municipality building its own fiber network.

As for WiMAX:
Clearwire has it available in Eau Claire. They also have a lease agreement with the Milwaukee Public Schools, Milwaukee Area Technical College, and the University of Wisconsin-Milwaukee for use of their wireless frequencies but I am not sure if they have live service.

TDS is supposed to have a WiMax service available in Madison. I also read a vague reference to it being available in Appleton but I think it is referencing a slower speed service which would also be provided by many smaller wireless internet companies all over Wisconsin. I could name three of these companies just in the Wausau area.

I bought a Motorola

I bought a Motorola Surfboard SB6120 when my old Linksys began losing connections after several years. I decided last summer that if I was going to replace it, I may as well go all the way, so I bought the 6120 and mated it to a D-Link DIR-655 wireless gigabit router, with a D-Link DGS-2208 gigabit switch in between.

I rewired using CAT6 and noticed a small, but real difference. I had Charter 10Mb down and 756Kb up service. The change was not measurable at, but I could tell that the pages loaded quicker. My guess is that the old Linksys may have been bogging down internally in such a way that speedtest didn't pick it up?

Anyways, a month or so ago, they doubled my speed (FOR FREE!!!!) to 20Mb down/ 1.5MB up. They have what they call "turboboost". During the evenings, I now run about 12-15Mb down and 1Mb up, but late night or at 4 AM (when I get up!) I can run at 25Mb down and 2.2-2.5MB up. I have been wondering if the DOCSIS 3.0 modem is helping these numbers, but I have no way of knowing.

After the long winded response, my short answer is that yes, I noticed a small, but definite, page loading boost when I switched to the new equipment. I also noticed that with multiple connections, I get bogged down MUCH less than I did before. By multiple connections, I mean that there are a lot of times where I am on my desktop, one of my kids is on their laptop, my wife is on her laptop and the other kid is playing PS3 over the net (wirelessly) with his buddy across town.

I also have the Motorola

I also have the Motorola Surfboard SB6120 modem. I am using it with a Netgear Rangemax WPN824 v2 wireless router. I also have Charter. I am currently on the 10/2 speed which is also offering PowerBoost. When I used last night and today I average about 20 Mbps for about half of the tests I ran. Otherwise it was anywhere from 10-92 Mbps with it being in the 40-60 Mbps range most of the time. I always get just over 2 Mbps on the upload.

We have two laptops, Xbox 360, PS3 and a Wii all wireless connected but it is just my wife and I so we don't experience any congestion on our network.

Just ran a test on

Just ran a test on and got a 120/2. I wonder how accurate these tests are for me right now. Before I got this modem I got 10/2 90% of the time.

OOPS! I'll bet mine is 20Mb

OOPS! I'll bet mine is 20Mb down and 2Mb up also.

I would think these would be accurate as my speeds also fluctuate now. I am betting that Charter has some sort of system that now allows more bandwidth during times of less traffic. I used to be rock solid at the same speed, no matter what. Now I am up and down, and am blazing fast at 4 AM when I wake up. Even at slower times, I still run very close to 20/2, but there are times when my downloads are much faster.

Charter has done a very nice job with this free upgrade, in my opinion.

You should be at 2Mb upload

You should be at 2Mb upload now. Charter now lists packages 1Mb/128Kb, 5/1Mb, 10/2Mb, 20/2Mb with PowerBoost list as available on all speeds except 1Mb/128Kb. I just got a letter in the mail from Charter talking about the upload speed increases and the availability of PowerBoost about a week ago. I am guessing that they must have some restrictions on the PowerBoost for each speed level. Otherwise why would you pay for the higher speed levels when you could potentially get the higher speeds with PowerBoost.

In light of Time Warner's new "modem lease fee" for Road Runner, will you buy your own modem?:
