@ Maccabi I cant find the MW3 specific ports posted on the main post. Can someone direct me to them? Thanks

I am not sure what you are able to run but I am pretty sure that there is not a router out there that has the ability to limit upload speed on an individual IP address.... which is what pretty much everyone on here that says to use QOS is trying to do.

 

Yes QOS can limit your bandwidth, upload and download, but it will not limit your upload to a single Ip address... so you saying that a person can use QOS to help with their gaming connection is incorrect.  A person can use QOS to limit bandwidth overall but not by individual IPs.

 

So yes I am right and you are a fool.  Correcting people is actually more fun than playing MW3!

You are completely wrong, which further shows me that you really just do not know what you are talking about.  I can shape based on port/port range (including being able to specify if it's the destination, source or both) , MAC address or IP address (again based on being the destination, source or both).  I can also specify which specific protocol it will apply to (TCP, UDP, ICMP etc).  On top of that I can use IPP2P or Layer 7 filtering which examines the packets and looks for a match of certain types of traffic.  So not only can you shape based on IP you can even have multiple rules for the same IP based on different protocols.  I like how you throw in at the end that other people are fools, when it is YOU that is clueless and ignorant on the subjects you are trying to inform people on. Perhaps you should actually do a little research on a subject you don't know much (or really anything) about before you start spouting off.

Also it's not ONLY about limiting bandwidth that other devices are using so there is some overhead left, it's about being able to prioritize packets in the send que.  As data hits the router, especially when the WAN connection is closer and closer to being saturated, things get put in a que to be sent out.  By prioritizing packets from your console you are allowing them to get bumped ahead of packets from other devices that are waiting in that que.  So if device A has highest priority and packets from devices B and C are flooding the router with packets, the packets from device A will STILL go out ahead of those from devices B and C.  By default it would be first come first serve, which could significantly raise your ping time.

Honestly I'm not sure why I'm even trying to explain any of this since you probably do not have the capacity to admit, even to yourself, that you are simply wrong.  I can assure you, however, that you are indeed wrong.

First i must say this is a great guide. When i first got MW3 i lag'd extremely bad. Then i remebered that i had this saved and bookmarked. So i looked this and entered in the ports for xbox since there were no set ones for MW3. It worked like a dream. I was averaging a 4+ k/d ratio every map every day for about a week. So my brother asked well i know BO is running fine but if we open ports for it will it run better? So i figured it do just the same he already averages 3+ k/d it might go up. Well i added a couple ports for BO so that gave me a total of 6 open ports. Like my luck as usual everything went to SH!T... My MW3 started saying NAT strict or lagging so bad it was unplayable. I was very upset. So i took off all the BO ports and it was still bad. I did a hard reset on the router and put all my settings back to the way they were and only added back the MW3 ports and it won't go back to the way it was, i still lag and it like im shooting air cause the bullets rarely touch the opponets when they're turned around standing still. Please help me and give me some advice. My router is D-Link DIR-655. My old Xbox redring'd so now i run on the MW3 limited edition one. i can do either hardwire or wireless(it was hardwire before). i run on road runner high speed. Any other info needed just ask. i wold love to ahve this fixed and actually enjoy playing again.

not sure exactly of your setup. But if you are wired into the router no MTU settings are needed. that is just for wireless.

 

I have 30 feet wireless to a linksys 54g router with no other devices in the home except my pc which is wired.

 

I use channel 9 on the router which (honestly) avoids the transmissions from my cordless home phone. When the router was on channel 3 (factory setting) the cordless phone (or other neighbors) only gave me 2800 bandwidth on the xbox. Now I am on channel 9 I get the full 10000 bandwidth speed all day long.

 

I think also some neighbor has something running in the area because my cel phone only gets on bar thru most of my house. Or it is still the cordless phone eatiing up the airwaves , which BTW doesnt always hang up properly.

 

Just to let you know so to help you from tripping on cables if you want to try it.

 

Game ran fine most of the time including Blops. Now the game runs perfect after the patch even if a "1 bar person" gets in the game.

First of all the MTU adjustments aren't just for people uwing WiFi.  Also a "full" 54Mbps does not equal to 10,000 of any unit that bandwidth is measured by.  So I'm not sure what you're talking, but I am pretty sure you aren't sure what you're talking about either.  While it's possible for a cordless phone to interfere with your WiFi signal the channels are packed into such a tight frequency range it's highly unlikely you'd be able to escape the interference by switching channels on your router.  More than likely any connection issues that were present were due to somebody around you having their router on the same channel.  In fact due to how tightly the channels are packed together you want to be on the furthest possible channel away from anybody else within range, because it's possible that another access point that is close can bleed over onto the adjacent frequencies.  And aside from all of that people trying to game on wireless connections is half of the problem with lag, it's likely a BIG part of the reason they ended up feeling the need for "lag compensation".  Because of all the clowns that insist on using an inferior connection type and on top of that many have a not so great signal on their console because it's halfway (or all the way) across the house from the access point.  Honestly I wish they could just segregate users by connection type.  People on wired connections get into lobbies with other wired connections and all the WiFi tools can have their own lobbies where they can all lag with each other.  WiFi is simply not good online gaming that requires low latency, the latency on it spikes up and down and is always going to be higher.

As far as your cell phone is concerned that's called being too far away from the closest tower AND being inside on top of it.  It happens.

You clearly must be going off of the speeds BO would show for your connection.  In case you didn't know that is a horrible way to tell how good your connection is for gaming and that little speed 'test' is horribly flawed.  First of all it clearly measures only downstream, as it would show me at 10,000Kbps (sometimes) which could never ever under any circumstances be my upstream.  Secondly it was hugely inconsistent, sometimes showing me in the 1800ish range, sometimes at the 2500-3000ish range, other times in the 5000ish area, others at 10,000.  This despite the fact that I'm wired and could run speed test after speed test from a PC connected to the same router and hit a steady 20Mbps (my maximum) every single test, to different servers, and using different test services.  Not to mention that even 2800Kbps is more than enough bandwidth to play CoD smoothly, WAY more than enough. 

The game also didn't bother to make any assessment of your latency in that test.  Latency is far more important, provided you have enough bandwidth (and CoD, even as host, doesn't require all that much).  I've sat and watched a real time graph of bandwidth utilization during matches, so I know how much it uses.  I will concede, however, that a latency test there would be pointless as the host is always going to change and be in different regions and with different qualities of connection between you and any given host.

And regardless of -anything- else playing on a wireless connection is going to add extra latency.  Your latency is also going to spike, and rather often, in most cases.  Like I've said before I wish they could just segregate people on wired and wireless connections.  Remove lag compensation for the wired lobbies and let all the wireless people suffer together, because as the saying goes "misery loves company".  And while it's true that under ideal conditions wireless only adds somewhere around 1-10ms or so of latency, not everybody is gaming wirelessly under ideal conditions.  Some people have their console halfway (or all the way) across the house from the access point, and have a less than ideal signal strength.  And all it takes is a tiny bit of interference for you to have lag spikes as the router or console has to retransmit packets.  Those are things that can happen even if your console is 20 feet away from the access point across the same room.  I don't think it's any coincidence the rise of the need for things like lag compensation happening along side the rise in popularity of wireless connections on consoles.
