Help, cable modem speeds are slooooow

[lost_wanderer]

I am at my wits end. I have kept ipv6 module from loading, tweaked
firefox, run sysctl -p and I have no Idea what to do. My windoze side
runs at 600 kps but my Ubuntu side would be lucky to hit 100 kbs. I have
run with firewalls up and down.
I am running a Motorola surfboard modem, Ethernet connected. Any hints or
direction

Thanks

Play around with the MTU settings for the ethernet connection.

Well, It turns out comcast had a few "issues". After I use the command
"sysctl -p" I am hitting 8000 kps on a consistent basis (And comcast
wanted me to pay extra for anything over 6000 kps. Thats sticking it to
the man!). If I don't use "sysctl -p" I will only hit 1200 kps. What
gives? Should I write a script to run "sysctl -p" at startup? I should be
able to tweak config file somewhere to preclude that. I am new to Ubuntu,
use to be a Mandrake fan (or Mandrivia now). Any direction would be
appreciated

Depends. What is it in /etc/sysctl.conf that made the drastic change in
your behavior? (running 'sysctl -p' with no parameters, by default loads
the file /etc/sysctl.conf and configures the kernel appropriately.)

Now I am really stumped, this is my sysctl.conf:
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

# increase linux autotuning TCP buffer limits
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216

# don't cache ssthresh from previous connection
net.ipv4.tcp_no_metrics_save = 1
# recommended to increase this for 1000 BT or higher
net.core.netdev_max_backlog = 2500

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_sack =1
net.ipv4.tcp_window_scaling = 1

nothing unusual here. Anywhere else I can look? Your right. Something
is setting my speeds to a default speed. But what config file is it?
Should sysctrl.conf be loading on startup?
