Background: A friend in the neighbourhood has a similar Internet package to mine. We are both on cable, 30 Mbps down, 2 Mbps up. When he connects to XBL, Black OPS 2, it tells him that he is connected at 10,000 Kbps. Which is the max it will display, so he is probably connected even faster than that. It tells me that I am connected at 940 Kbps. Less than 1/10th his connection speed. I have a hard wired connection.
I connected directly to my modem I get connected at 10,000+ Kbps too. I connected back to my DIR-655 and disconnected all other devices and turned off the wireless. So there is only my XBox 360 connected to the router, I am at 1,000 Kbps again. Back to 1/10 the speed.
I have a Thompson DCM 476 cable modem Software version STAC.02.50, DIR-655 Ver B1 Firmware 2.04NA. I believe I followed the set up in post http://forums.dlink.com/index.php?topic=47344.0 I have reserved IP's for all of the devices. I have QoS rules for two XBoxes to have port 3074 forwarded, Endpoint filter is set to independent, anti-spoofing is enabled, WISH is disabled, UPnP is enabled, MTU is 1500, etc.
Why is the DIR-655 restricting my XBL connection speed? What parameter am I missing that I need to change?
Thanks for the help.

Port Forward is not needed for XBL. Please use the Multi-Xbox rule listed in the sticky.
-
Thanks. I used the wrong verbiage. I am using QoS not port forwarding. I only have a multi-xbox rule though. Am I supposed to have all of the rules as in the post? What about the remote IP address, are they to be the same. Sorry, not an IT guy.

If you have more than one xbox yes, use the 1 multi xbox rule for all xboxes you have. Use 0-65535 for port range and remote range use 0.0.0.1 to 255.255.255.254.
-
Thanks. That is how the QoS is set up. I am still only getting a connection speed of ~1,000 Kbps on a 30,000 Kbps connection. Is there another setting in the router that could be restricting my access speed?

Internet Service Provider and Modem Configurations
- What ISP Modem Mfr. and model # do you and your friend have?
In gaming are you seeing 4 green bars and OPEN NAT?
- Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.

Thanks again. I have 4 bars 99.9% of the time, open NAT. I use Cat 6 cables. My cable modem is Thompson (Technicolor) DCM 476.
Just for the heck of it, I decided to change my MTU setting to see what would happen. The default is 1500. I changed it arbitrarily to 1450. No real reason for selecting that value. Voila, my BO2 says I am connected at 10,000 Kbps. The caveat though was that the connection seemed choppy or jerky. It didn't seem smooth. I changed the MTU to 1460 (arbitrary again) and I was back to a BO2 connection of 1,000 Kbps. These MTU settings didn't seem to affect the speed tests on my PC. Is there a correct setting or is this something I should get from my ISP. I thought the MTU was what the router would pass through without fragmenting. I believe Xbox packets are 1364 bytes. So I would have thought the router setting of 1500 would not affect the throughput from Xbox. Why would changing the MTU to something lower have a positive affect?
Cheers,

I recently changed my MTU value on a recommendation of a friend of mine to 1365. Have been running well on it, however BO2 reports 1800Kb. I'll try your value and see.
There is some MTU information here:
