(adsbygoogle = window.adsbygoogle || []).push({}); Ok well I always research things in a lot of depth and I published lots of ways to beat lag comp in MW3 and someone was so pleased with my help once he paid me $60 via my website. Im not promoting the site so I wont link to it I am a NGU faithful and I'm just sharing something that helped me.

The matchmaking and best connection thing is the best its ever been in any cod. The fact that players are experiencing varying degrees of LAG is almost certainly down to their own connection. I was raging about LAG as I got the best internet etc paid for fibre optic, ethernet cable etc and I thought I was being punished by LAG comp.

Not the case at all if it wasn't for LAG comp I would not be able to even play cod. Basically as memory has become cheaper router manufacturers have added more and more memory (cheap ass memory). Great right? ... well not exactly.

In order to maintain network integrity while everyone in the world is sending packets at the same time some packets have to be momentarily delayed to avoid being fragmented. This happens both on your router and of course on a larger scale your isp's exchange routers.

I ran a network diagnostic tool on my own connection and I am not talking about pingtest.net or speedtest.net I am talking about a professional scientific network analysis tool called netalyser (google it use the downloadable .jar not the online version). To my utter amazement my top spec fibre optic low latency internet had a 4447ms buffer delay while playing Black ops 2.

Imagine being in a lobby where you had a 'real' ping of 4447ms and no LAG comp? People would drop you before you had even seen them.

The problem is that your (or your ISP's) router can become bloated completely unpredictably and be great one second and awful the next. As your router has to 'hang on' to more and more packets in the memory it becomes full and responds slowly while 'bloated'. So even though you have an amazing upstream that upstream is being delayed by in my case 4.5 seconds by your own router.

It is for that reason that being host sucks in MW3 and most of the time in BO2 a little lag comp (too much in MW3) but mostly host=more packets more packets=more bloat.

They are working on a solution to buffer bloat with routers with better memory management but they wont hit the stores till 2015.

There are a few things you can try optimising your MTU to stop packets being fragmented because they are too large for example most ADSL lines this number is 1472. There are plenty of tuts on here and YT to help with this.

Also you can avoid host by closing ports to make your NAT moderate.

But what worked best for me and is a real game changer was this. Download virtual router manager (google it) on a windows 7 Laptop and share your windows 7 laptops connection wirelessly. Then connect your console to your virtual wireless network through your windows 7 Laptop. Im not sure why using your laptop as a router works but I think this works because the laptop has better memory management and more memory than my cheap ISP router.

If it doesn't work for you I am sorry, It PROPERLY worked for me and my clan but I cant speak for your individual problems. I hope you at least enjoyed the information.

I am now very much enjoying the LAG and now I am better informed about my own connection I am glad of LAG comp =]

Just a quick note about MTU my default MTU was 1500 and 3 out of 4 packets that I sent to google.com via command prompt were being fragmented. At 1472 4 out of 4 were complete.

If enough people want I will make a Vid tut on diagnosing if the LAG is from your own network.

lol, I can agree slightly with the bullshit claim here. However, there is also some validity to adjusting MTU to decrease packet size and therefore cutting back on amount of bad packets sent (of course this is all theory). So in theory the larger the packet sent the more of a chance you have to have fragmentation and lost bits. One lost bit = one lost packet so if your packet is sent at 1500, and one bit (or byte) is off and the CRC doesn't match and say the receiving end only gets 1499.9 that entire packet is then resent. So if you cut down the size of your packets (maximum transmission unit) you are then able to technically speed up the process as your packets are sent in smaller chunks and if there is an error in transmission the packets are able to be resent quicker because they are smaller.

Now at the same time there is a downside because sending packets that are smaller than average can kick up alerts at your isp and you can potentially be stuck dealing with what is known as traffic shaping. So you can be throttled back.

So if you are going to adjust MTU don't adjust it down too much because you WILL degrade your performance. Adjust it too high and again degraded performance. It is a major balancing act and somewhere between 1472 and 1500 will provide "peak" performance.

You can adjust MTU on your router itself. If you don't have your manual lying around search for it on the interwebs. Most manufacturers will provide info on how to adjust most settings. Just be careful with MTU settings! Write down what works and revert back to that number if it causes problems after an adjustment.

Thank you so helpful just helped my lag alot

Did you even read the wiki article I posted? Did you google buffer bloat? Its not bullshit its a real phenomenon and is being described as a fundamental flaw in tcp routing protocol by some scientists.

If you read the article you will see that playing video games or voip over a network suffering buffer bloat can be "near impossible".

Why do people always call bullshit even when they dont understand.

For the record I was agreeing with you for the most part. Adjusting MTU can be a very BAD thing though depending on your hardware, connection, etc... Was just pointing it out. Some MTU adjustments make things worse.

Fair enough but it sounded like you were saying its mainly bullshit but getting mtu right is a good point. Mtu wasnt the point the point was there is something causing lag that were only just finding out and the best internet wont help.

That's for damn sure, because at some times it is the bitch that is on fucking dial-up that is raping everyone because that shitty lag compensation is giving them a HUGE advantage. lol

really helped dude thanks

People are still reporting this is working for them.. I still use my laptop as a router and im doing much better in most lobbies feels about right 80% of the time unless I get a bad host.

great job !!
