Comcast WinMX Bandwidth gone ... where did it go and how do I get it back? drscottlv 06-02-2005

Hi Group,
Interesting dilemma ... I have blazing fast Comcast download speed
shown by DSL reports.

Up until about three months ago I got download WinMx bandwidth between
200,000 B/s and 100,000 B/s. I could download 20 songs simultaneously.

Now my bandwidth averages less then 20,000 but spikes up to 200,000 for
as long as an hour and then settles back down to 20.000 to 30,000 where
I am lucky if I can get 1 or 2 downloads going. Feels like I have gone
from high speed to dial up for downloads!

I limit upload bandwidth to 30,000 B/s. My allocated bandwidth is 15
KB/s out 22.5 KB/s in. I have had 2 Comcast service techs come out
after I tried three different Linksys routers and three different
computers .. all with the same result. The first techie didn't have a
clue .. said he was going to have a supervisor call me and they never
did. The second tech came out and said:
>From Comcast tech
OK ive spoken to management and i got ahold of this lady in our
headend, had her runs some tests within our system she claims that
everything checks out but i wasnt satisfied with that so i spoke to
some techies within our company and they gave me a url to download from
thats within our system, its a server thats within our ring with a
40meg download. so i went with my lap top to varius places with in our
system including your corner of Dublin and i was able to download at a
rate of about a min and half or so to download that huge file.
so the conclusion ive come to is theres got to be a server thats just
outside of our system thats losing the bandwidth as you venture into
the world wide web. The downside to this is its not within our system
so as a company comcast wont track it down uless its within our
system. Like for example if someone in your neighberhood was breaking
our service agreement and was running a public server with thousands of
hits a day then it would effect your node but sucking up all the
bandwidth. But with extensive tests thats not happening. If i could
paint a picture of our system its like almost a circle and there is one
main junction that connects our system to the world and if that first
stop (server) on the www is losing bandwidth then it would effect you
and many others there for causing a wide spread mass of service calls
but thats not happening either. sry to say with all my extensive
research and pushing to all sorts of departments myself and many , many
others have not found any loss in our ring of the system. My supervisor
told me if you wanted to you could try out other types of connections
to the internet but he feels you would still be having the bandwidth
loss meaning that some company outside of the Tri Valley (server) is
screwing up the bandwidth on the internet.

Wish i could do more but ive hit a dead end my friend (which means
Comcast won't help)
*******************************************************

Virus scans, spy ware scans, ad aware scans and port scans show no
problem. I can find no background programs sucking bandwidth ... any
ideas?

Anyone else having this problem??? Please email response to

I was having a problem like this a while back. However my downloads
weren't going up high and then coming back down they just weren't
going stong for months and then didn't work at all. I'm hoping with
all the knowlegde it seems you have that you do infact have port
forwarding enabled through your router for both the TCP and UDP ports
and are making a primary connection to the network? Another question,
are you sharing any files for upload? Some people out there have apps
that can check to see if you're sharing anything or not berfore they
allow you to download from them. What error messages is WinMX
throwing up at the user level in your transfers screen?

Hi ringfinder
Yes I have port forwarding through my router .. if I didn't I don't
think I woukd get any bandwidth .. and yes, I am sharing over 750
files.

I just noticed that each download has a plus next to it and when I
click on the plus I see several people are downloading the same file as
I am .. I just hope not at the expense of my bandwidth...the mystery
continues. I have no error messages.

Many ISPs are starting to throttle the bandwdith used by common P2P
programs, they do this by limiting the bandwidth on certain port numbers
(ie. the default port numbers used by P2P programs).

The solution is to change the default ports. Pick a random number between
49152 - 65535 for the port number (this range is reserved for dynamic and
private ports).

There is equipment that detects P2P traffic regardless of which port
it's on. If the OP's ISP uses that kind of equipment, then things get
trickier because simply changing to a higher port won't help..
