If anyone has set up QoS on the Dlink 2640U can they plz help me out. I bought this router to replace my old mega100 and lots of ppl online have posted about how the QoS is decent but I can't find anything to help me set it up!

Buggered it up...
I have this router, and am trying to configure QOS.
After playing with it for 30 minutes, it stopped working
I had to do a factory reset to undo my changes.
Have you been able to find a solution to this?

if you want real QoS get a mirkotik router, that stuff gets the job done.

I wonder where he read that! I've never had any success with QoS without actually limiting traffic too.
+1 to what hereticangel said! And even with the MikroTik router, you'll also have to specify hard limits to certain traffic if you want QoS to work properly for gaming.
Like for gaming, I typically reserve half of the bandwidth on a 4Mbps line for games. I haven't managed to set mine up so that it would allow the full amount of bandwidth when no one is gaming.

What software version you running? Under Device Info

I know it's off topic but what queue type are using?
I've had fairly good success using pfifo, just make sure you mark all the traffic and not just the gaming traffic.

I've tried many things.
I used pcq (src / dst IP address classified) & pfifo queue types - both with Simple Queues and Queue Tree.
At this very moment I rarely play games, so I'm just using Simple Queues (with pcq queue type) to give equal Internet bandwidth to each LAN IP address.
At my office we're using a Queue Tree with all the nodes having pcq (IP address classified) for their queue type. Upload shaping/prioritizing is really working well!

Would anyone like to shed some light what QoS is and what the point of using it is? I have a DSL-u2640u also, saw the QoS thing but have no idea what it is 
wikipedia doesn't give a simple answer.

QoS gives priority for certain packets, but on its own it will not keep your game's latencies low, because your bandwidth will be saturated by the other traffic.
The other issue with QoS is that you have to shape/prioritize the outgoing traffic too, because you have VERY little control over the shaping of the incoming traffic. The only way you can shape the incoming traffic is by adjusting the TCP window sizes and dropping TCP packets. So you have no real way of shaping incoming UDP traffic.
Unfortunately I'm not sure what the QoS on the D-Link modems do. It could be that they're just marking the DSCP flag of the packet, and then basically relying on the upstream router to shape the traffic. If this is the case, then it is utterly useless with our ADSL infrastructure.

Damn ... VERY old post you guys brought back to life here ... i'm sure the OP doesn't care any more.

Cool thanks Pada, guess I will just disable it on my router seeing now that it's actually enabled.
I took screenshots of the settings in my 2640u in an effort to help OP, his might be slightly different given the different types of firmware. Also I have edited the screenshots to show the options available from the drop down menus.
In order:
Quality of Service - 1
QoS - Queue Config - 2
QoS - Queue Configuration - 3
QoS - Classification - 4
QoS - Classification Add - 5
lol seeing that the OP doesn't need the help anymore I will leave this for anyone else who may need it to help someone else

Thank you for all the responses (I was actually caught by surprise) - I am going to mess around on my router this evening, get a few screenshots.
I have a 384k line - when my downloads are active, my wife complains that her facebook doesnt work anymore.
So, the first step, is to give port 80 preference over the torrent port.
As I said, when I tried this last week, none of my networked devices could even ping the router.

with a 384kbps line, giving priority to certain traffic has a very limited effect, unless of course you limit the other traffic to a near halt.

Here is what I was expecting:
I currently download torrents at 30-40 kb/s. I have this running 24*7.
When I try to facebook over this same line, it is unusably slow - this only happens for 30 minutes or so per day.
So when I facebook, I want my torrents to slow down to a crawl, and facebook to get the 30-40kb/s.
The issue is that I want my router to do this dynamically so that I do not need to turn the freaking torrents off and on all the time.
I thought that QOS is the way to do this, saying that Torrents have a small priority on the line, and port 80 has a high priority.

I don't know of any router / QoS setup that will do that for you automatically.
Torrents are one of the most difficult things to shape.

maybe download using nzb's. i know i leave my nzb's running then the download automatic goes slower if someone loads a website, though maybe that happens at mweb side, i have no QoS setup.

I have to pause/limit my NZB downloads if I want to browse websites (other than forums), because my NZB's will keep on going at 100kB/s on my 1Mbps Mweb uncapped.
When I use queues to give equal bandwidth to all my LAN PC's for Internet access, then my NZB's will download at like 50kB/s as soon as I start to download content (also at 50kB/s).
Automated QoS works wonderfully for splitting bandwidth between downloaders, but it doesn't work that well for gaming/browsing, because the gamers/browsers cannot use their full share of the bandwidth.
