It's not a pile of junk and it probably isn't broken. Turn off all
connections and then ping the gateway and see what you have.

   The Surfboard is an excellent quality modem. If you have upwards of
15 Gnutella connections open at one time, you will have problems with
any connection. That is a very large amount of bandwidth you are talking
about using at one time, so of course your pings will be poor. With that
any open connections, you are probably overtaxing your PC as much as
your connection. I have used Napster and Bearshare in the past and had 2
or 3 downloads going simultaneously, but at that I saw a slight
difference in speed as I started each download. I imagine at 15 it would
have been crawling and I know I have a good connection, as well as a
1.4Ghz system.

Just to clarify - The gnutella connections have at most 2 or 3 KB/s 
going across each of them - just queries from the network about what 
files are in my database.  I tend to think it isn't a problem with my 
bandwidth being used because the problem starts to occur very sharply 
when more than a certain number of connections are open.  Pings will 
jump from 80ms with 10 hosts, to 3000 ms with 15.  Not exactly a linear 
trend...

Some more info:

When the problem is occuring and I ping the modem itself 
(192.168.100.1), response time is fine, <2 ms.  When I ping my gateway, 
the problem is evident, large packet loss and several second ping times. 
  If I turn off gnutella, wait a moment, and try the same thing, all 
pings are <10 ms.

This should tell you that 15 connections are killing the connection. Ping the
gateway with 5 connections and see if it works reasonably. Be happy with what
you can do, not what you want to do. Pretty apparent that 15 connections is
excessive.

I'm willing to bet your problem is limited upstream bandwidth.  Even
though you are mainly downloading, you must send the servers a bit of
data to confirm that you are still there and are getting the data.  If
those packets don't make it, the server assumes it's drowning you with
data and cuts back.  If you have a tool to watch your upstream bandwidth,
I'll bet it's approaching that magical (terrible) 128 kb/s figure.

   Arg, you seem to be entirely correct... I downed the response limit 
from 30 results to 1 and I can easily maintain 25 connections without 
problems.  Checking the bandwidth usage, things start to fall apart 
right around the 14 - 20 kilobyte / second upstream rate... That sucks. 
  Guess I'll be looking into DSL ;)  Many thanks for the assist..

that is amazing!  A real person who likes doing 50 things at one time.
That's too much like work for me, but I'm glad you got things worked out.
Merry Christmas and Happy Holidays.
