Ok, I'm getting ready to move to a location that offers cable modem access through Comcast@home. They claim that it is 100 times faster than a 28.8 connection. In theory 28.8Kbits/sec is 3.6 KBYTES/sec. So does that mean you can d/l stuff at 360 KBYTES/sec? I know that you can only d/l stuff as fast as the server you are connected to will allow, but has anyone ever seen speeds on their cable modem connection even remotely that fast, say 200 KBYTES/sec? Just wondering.

Feel free to post your fastest speeds as well as the speed you most often get, on average.

Thanks.

My cable modem is not Comcast, but when it works right I get anywhere from 15 k/sec all the way up to about 90 k/sec. Average is around 30k/sec.

Bear in mind that my cable company, when it first started this, had no clue. They have been bought out by Charter Communications and when the internet service is switched over, I expect those numbers to improve.

Even if they don't, it beats a dialup.

i've maxed out at 210 KB/sec from some fast servers. My typical performance is under 150 KB/sec, but 99% of it does depend on how fast the server is.

btw-I'm on Charter@home in GA, running a yikes! G4.

My cable is Bresnan@home, which was just bought by Charter...

If I mark my speed by using this page: http://computingcentral.msn.com/topi...eedtest500.asp , I am consistently 14000-19000 kbps, 150 Kbytes per second. Is this speed real? I dunno. When I use Anarchie, I regularly see speeds around 79 k/sec... I downloaded the full install of Outlook Express in less than 90 seconds. So I guess, it depends.

The downside? Cable is "out" of service a lot more often than my old ISPs combined. We have been "out" for up to 6 or 7 hours at a time, and in 6 weeks, we've been out *at least* part of one day a week--and it's not always during the graveyard shift, either. And it's more expensive than most dialups--$50 here if you don't have cable TV, plus $10 for my husband to have his own email account/IP address.

Plus side? Static IP address, so no DHCP stall trouble. Superfast downloads and uploads when the system's working. And it's always on. It's really, really cool.

I'd be hard-pressed to go back to dialup.

I have Road Runner, and just checked the speed using MSN's Bandwidth speed test ( http://computingcentral.msn.com/topi.../speedtest.asp ), and I currently have about 1.6Mbps which is about 200KBps...

hope this helps!

My Cable modem speed is:

568.4 Kbps/sec

or

69.7 Kbytes/sec

I average from 40-100KB/sec on the @home network (when it's not down).

42 dollars but still worth it!

I just tried the link for the cable modem test and I got 774.8 Kbps or 94.9 Kbytes/sec. I have tried this before and have gotten faster speeds. When I get online late on a weekday night I can download a 11 Mb file in less than a minute. I am on the @home network and my city just had the cable service upgraded and replaced just before AT&T took over. There is [b]NO<b/> way that I would ever give this up. If I use Anarchie to download big files, I can average about 300 Kbytes/sec on a fast server. If you don't have cable modem and it is available; GET IT!! The pros out weigh the cons.

Just tried the speed test and got 46k and 67 k/sec. And I wouldn't go back to dialup either, even though there are problems. The service is still less than two years old. I wonder how bad TV service was two years after its inception?

Using the Netvigator service here in HK, I get constant speeds of approx. 180k/sec for local servers and up to 120k/sec for overseas servers.

Well, don't know about you, but the cable modems here I've seen max out at 1MB/s... cable here is somewhat new though, explains it, and we are not in an extremely populated town.

Cable modems share bandwidth with the other people on your part of town. So if you live in the getto and are the only person around with a computer, your cable will haul. If you live and in area with lots or apartments etc you probably won't get such great performance...but it will still probably beat the pants off of a modem.

Some cable modem providers offer different speeds too, that could explain some of the different results you are getting. For example where I live you can either get a 64Kb/64Kb or a 1Mb/128Kb modem. Where the first number is the down side (stuff from the net) and the second is the up side (stuff you send to the net).

Also I don't think that a KB (kilobyte) and a Kb(kilobit) are the same thing...just to clear up any confusion. A KB is 1000 bytes. One byte is 8 bits. One Kb is 1000 bits. Usually network bandwidth is measured in Kb/s (kilobits per second) so a 56K modem would be 56000 kilobits/sec. This translates to 7 KB/s. A 1Mb cable modem could bring down 1,000,000 bits/s which is about 125 KB/s. Of course all these are the theoretical maximums so your results may be somewhat different.
