How many of you own your own Cable Modem?

If you do, what kind do you have? I'm thinking about buying one insead of renting it for $5.00 a month and then going to a faster speed.

I bought mine. Bought it couple of years ago...and they have replaced it twice.

Mine is this gray shark-fin looking one.

Thinking of the same thing Gary... I can buy mine, get $5 knocked off the monthly cable bill and a 5 year warranty.

Mine's a Motorola Cybersurfer FWIW. I'm just renting it right now... just wondering if one buys a brand new one other than the one the cable company has here gets me 5 yrs. warranty too and how much they are. I can have this one for $60.

Gary, I have a Toshiba PCX1100, which I bought three years ago for $200!!!  sad.gif Needless, to say, they've gotten much cheaper since then...) I've had absolutely no problems with it though. smile.gif

It's a 10BaseT modem - newer ones are faster, I suppose. (Anyone noticed if this makes any appreciable difference??)

Toshiba also now have cable modems with routers and wireless routers built in, so you may want to consider that option too.

I bought my own at a Swapmet and got it for 30.00, it sells for 79.99 at Fry's, but i would rather have my own then give the extra $ to the cable company...

Check ot eBay or Yahoo and find one cheap...

I bought my DoxPort COM 21 when I first got hooked up to cable. It's too long ago to remember the cost. blush-anim-cl.gif Or, maybe my age has something to do with it.  huh.gif

I believe it transfers data as fast as anything sold today. When the cable was first hooked up here, the cable company didn't reign in the speed limit. I used to get better than 2 Mbps downstream! The cable company wised up and now I get closer to the advertised 1 Mbps downstream.

Paddy,

Staples has a Toshiba fo $89.00. I looked at it yesterday.

I got into this because I saw a commercial on TV from Charter cable, my ISP provider, saying that new subscribers get a FREE modem if they sign up now. So I called them and they said I would have to cancel their service for a month, pay the disconnect fees and the new connect fees to be eligable!.......the modem isn't free anyways but it's a free rental.

What a joke. wacko.gif

My modem is a  Surfboard SB4100 and works great (but I do wish it had a reset switch on it) and is owned by my ISP-Comcast.

Formerly, the rent was $5.00 per month. Comcast apparently concluded that too many customers were buying their own modems, so they reduced the rent to $3.00 per month. And oh yeah, at the same time they increased the service cost by $2.00. doh.gif  eek2.gif  taped.gif

Sounds/reads like your ISP considers you as a number in their data banks .. period .. Gary.
The days when you're asked for your name so they can look up your account from the other end of a phone conversation are fading fast.

Now that Costco (fairly large shopping center) will be built close by, Comcast is coming out of the wood works with flyers to join their data banks. They just bought the cable company here. Same employees, equipment, trucks from the last company. Just changed the logo on their trucks and handed the drivers new shirts.
Guess I should check what they have to offer.

My cable modem comes with my internet package.  When I'm done with their service they will pick it up.  Whenever that may be.

Motorola SB3100....

I should find out if they would break me a better price if I supply my own modem.  Mine is pretty old already.  Any advantages if I were to get a newer model?

I just went to Best Buy and bought a Motorola Surfboard Model SB 5100. $79.00 with a $20.00 rebate....so $50.00. smile.gif
 
It's nice. It had a standby switch so you can disable it...doubt if I'll use it.

Called Charter and upped my service to the Gold package instead of the Silver package for $5.00 exculding the old modem rental. So now I'm at 768bps instead of 256bps. I was going to go for the 1.5bps but I thought twice.thumbup.gif

Well, I ran some tests and it's working at around 947bps. WOW.gif

Better check with your ISP to see which modems will work with their system. I am  happy with my Surfboard 3100, no problems. There should be a  list of acceptable modems on the ISP's web site. Cox Cable, here in Kansas, has such a list--or at least they did when I bought mine.

It works with my cable company. all they required was that it be Docsis compliant.

"Docsis compliant."
I'll bite.?.
What is that? <g>

Bbob offers good advice.

I am a Cox subcriber and they gave me (as part of a promotional deal) a Surfboard 3100 to access their service. It works very well, and I own it free and clear. Unless it's a very proprietary or expensive device, I would never consider renting.

Bill,

Docsis compliant... I don't have a clue. biggrin.gif I think it has something to do with termination.

DOCSIS means "Data Over Cable Service Interface Specification".

The AD8326 and AD8327 DOCSIS-complaint line drivers are engineered for cable modem and set-top box applications. The AD8326 is a differential output five-step line driver that can perform complicated design modulation techniques, such as 128 QAM upstream, offers a step size of 0.75 dB, and features a harmonic distortion figure of --51 dBc at 65 MHz. The AD8327 is a single-ended coarse step driver with distortion performance of --57 dBc at 65 MHz. Additionally, this IC features a step size of 6 dB, making it well suited to work with chip sets that have a built-in fine step attenuator function. The AD8326 is housed in a 28-lead TSSOP while the AD8327 is supplied in a 28-lead PSOP.

wink.gif Well...that might as well have been Chinese...(would ask the resident EE, but he's upstairs snoring right now...)

Perhaps the Webopedia definition will prove a tad less, um, oblique, to those of us who don't have PhD's in EE.

"Developed by CableLabs and approved by the ITU in March 1998,  Data Over Cable Service Interface Specification  defines interface standards for cable modems and supporting equipment.

With certification from CableLabs, manufacturers will be able to produce cable modems for retail, so consumers no longer have to depend on leased cable modems from their cable providers.  

Other devices that recognize and support the DOCSIS standard include HDTVs and Web enabled set-top boxes for regular televisions.

DOCSIS specifies downstream traffic transfer rates between 27 and 36 Mbps over a radio frequency (RF) path in the 50 MHz to 750+ MHz range, and upstream traffic tranfer rates between 320 Kbps and 10 Mbps over a RF path between 5 and 42 MHz. But, because data over cable travels on a shared loop, individuals will see tranfer rates drop as more users gain access.

In 1998, there were 1.2 million cable modems installed across the United States with an average price of $245 per unit, and by 2004, research reports predict there will be 24.3 million units installed across the US with an average price of $50 per unit."

There are also two DOCSIS standards - 1.0 and 2.0. From castlenet.com (an ISP who coincidentally happen to use an iBook as an illustration on their homepage! biggrin.gif):

"The DOCSIS 2.0 Compliant Cable Modem is specially designed to enhance the bandwidth of the upstream up to 30Mbps. And it still works with all existing DOCSIS 1.0/1.1 compliant head-end equipment (CMTS) and Multiple Service Operator (MSO) networks.
