- New here... with a problem of course.

I am not very smart when it comes to all the tech talk involved in ISP.
I have a Motorola SB5100 and my service provider is Adelphia. M
connection is good for a while when I am connected, but then the spee
drops severely for a few seconds. This isn't a big deal when I am o
the internet, but it kills me when i am on XBOX live. I get kicked ou
of games because my speed drops. It is really frustrating. I have ha
the cable service for about 4 months, and during the first 2 nothin
like this happened. Could it be the modem? I can give you mor
information if you need it. Thanks for the help

Since your provider is set to become either Comcast or Time Warner on the
horizon, and Adelphia is not in super helpful mode leading up to the sale,
you may have to wait and hope. Not sure about the actual problem, sorry.

Strange. If the modem power is connected to a surge protector, connect
direct to the wall outlet. Reboot the modem (it will reboot on resuming
power when changing the outlet; otherwise remove and then restore the
power adapter to reboot). Have a look at the modem information web page
http://192.168.100.1 and post back the upstream and downstream power,
signal to noise ratio, etc. You can consult the cable modem faq at
www.broadbandreports.com for additional information. You also might
post to the Adelphia broadband forum for specific help. You should have
the power information when posting there.
Do you directly connect, i.e., no router? What is your firewall and
anti-virus (hopefully you have both)? If there is no router, do you
reboot the modem before connecting the xbox?

Frankly, DSL is better for gamers.

ADSL is also shared. Only the copper pair between the subscriber and DSLAM
isn't shared. I was recently working on some ADSL systems. On them, 2
DS3s where shared among 448 subscribers, each configured for 3 MB down.
That works out to 2 * 45 Mb / 448, less ~15% ATM overhead or about
170Kb/s, if every subscriber were trying to download large files at the
same time.

it sounds like your node maybe over populated.
The node is where all the connections in your area go
before connection to the sever. Hey, it could be the sever also.

What are you basing that on? My observations are from actually working on
the DSLAM shelves. The equipment I was running acceptance tests on , only
supports a maximum of 4 DS3 connections, which at 45 Mb/s each, means the
system is capable of a maximum of 180 Mb. So, even with all 4 DS3s in use,
if each users was doing a lot of downloads, they'd only get about 340K b/s.
Since in these installations, they were only using 2 DS3s, that works out
to 90 Mb/s total or 170K, should everyone be downloading at once.

lines, before 100 or so customers are online. If the cable provider
doesn't overload a node (some don't), there is little problem.
Nevertheless, cable is usually subject to more fluctuation of bandwidth,
and latency, than DSL. Most gamers are more concerned with response
than massive data flow.

If you look at bandwidth/users, I think you'll find similar numbers either
way. As for latency, that's one of the things we measured in the
acceptance tests using ping. The spec called for 16 - 18 mS to the router.
A quick test to my cable ISPs router shows about 6 - 8 mS, so the latency,
(here anyway) is less for cable.
Has anyone actually performed comparison tests, between ADSL and cable? Of
course to be accurate, you'd have to do the tests multiple times and on
multiple ISPs. Bear in mind that how the ISP has configured the network
(including bandwidth/user) will have a great impact on performance,
regardless of the technology used.
