I have been using DSL for a couple years now and it has worked well, though peak download speeds are limited to 1.5mbit/sec. I activated 6mbit cable modem service today and was surprised that speed tests were around 1mbit!
I decided to take the router out of the picture and was SHOCKED to see speeds ranging from 4-6mbit/sec!
I turned off QoS and my speeds went up to 3mbit or so, though this is only half the speed I should be getting.
I am running DD-WRT v23 SP1 Final (05/16/06) mini with default settings for everything except wireless, though that shouldn't matter since all tests were run using a wired connection.
What on earth would cause this sort of performance hit?
I have tried tweaking MTU, using values from 1200-1500, as well as auto. Anything below 1500 just slowed things down. Is there anything else I can try?

not running any p2p programs?
is this a fresh dd-wrt install?
are you wireless or wired?
The problem isn't the desktop... it's the router. When I take the router out of the loop, speeds skyrocket. Is this a setting I can tweak in the router itself?
Or will the RWIN make a difference when connected to the router?
Are your router and modem close together? On another site I read that electrical interference was the problem, his case was just like that. If they are, move them further apart.
I don't think electrical interference would cause this sort of problem with a wired connection. I have also noticed occasional stalls since upgrading to the cable modem, which leads me to believe that there's an issue with the software on the router.
I may try downgrading to the vanilla Linksys firmware and see what happens.
