Repost: Internet Access Problems

I have a D-Link 530 TX+ card with a Realtek 8139 chipset in it.
I’m getting really slow internet access. About 6 KB/s for about 2-3
seconds, when the page starts to load, then it drops to less than 1 KB/s
for a while then there will be the occasional spikes of speed every
20 seconds or so.

I was told to run nicinfo after a couple of hours after being online and
here is what it gave me.

Thanks for that information. Okay, so how are you connecting? Cable Modem
and RoadRunner? One thing you might try is lowering the MTU on the
interface. Try this as root…

slay -f io-net
io-net -drtl mtu=576 -pttcpip
netmanager


Now, I am not gonna say this will work for sure, but some people using
other OSes have had success with this approach.

Yes, I’m using the Road Runner service with a cable modem. I’ve tried
the above and now i’m up to about the speed of a 14.4 modem now. I’ve
tried various MTU settings.

Okay, here is where it gets fun. From your previous postings we are
not dropping any packets (or at least not seeing them get dropped). So
can you try the following…

traceroute ftp.cdrom.com

from your machine and post those results. I am curious to see where the
overhead is coming from. Also, if you ping your gateway do you ever
see any packet loss?

pinging my gateway causes no packet loss.
