I felt my other thread was getting off topic so I created another one to discuss lag issues with gaming.  Anyway saw this interesting thread on the MW3 forums.

http://community.callofduty.com/thread/200409455

Has anyone else done this while playing on line?

[FurryNutz]

Wonder that MTU number the used. I know for Cable it's 1500 and DSL it's 1492. I'm getting ready to setup the 4500 again.

[FurryNutz]

OK, I installed the 4500 again today. Did some Wireless and wired gaming. Noticed that I couldn't get full bars ok MW3 if i left the NAT settings at default. So there back and Endpoint. I noticed that it won't give me 5Ghz wireless status on the xbox for some reason. It will for my Mac Book. Odd. 2.4Ghz it reported the connection.
I didn't set up an GF rules. Have OPEN NAT on MW3. Only think I did was disable Dynamic Fragmentation and turned off WISH and WPS. All others is set up as default with reserved IPs. I didn't have a greatest night in gaming but was ok. I think I'm more tired. Didn't see any lags. Did have a few games where it changed hosts. I did notice that when I was hosting with 2 people in my lobby, our signal was low, in the yellow. This was wiredless. We all played well accept for dealing with the cheaters, hehe.

I'm getting 2500something on the automatic uplink speed measurement. I took a capture and will post it.

I'll try some logs tomorrow.

Ok, I have PT enabled again, played 3 games last night.

Game 1: killed confirmed on Black box:  I went negative 7/11, hit detection was okay, I think I did bad because its a new map and the other team was real campy, The game reached its time limit before any team reached 65 since people were camping so bad. Final score 38 to 43 (loss). 
Verdict: to be expected with a new map and going against a team who likes to camp, I can accept this but then again 3 people left the game before it ended, poor sports or too much lag?  I don't know.

Game 2:  Domination on Black box:  Hit detection was really good, went 12/7 and won. No lag noticed in this match. Yay!

Game 3:  Team death match:  I pull host, hit detection is really good again maybe even great.  I even got a triple kill with a bouncing betty! lol.  Things going good, close game but my team is winning, the game gets a little glitchy, then I get kicked and I am sitting back in the lobby all by myself!!!

I have encountered at least 3 disconnects this week and this would very rarely happen before!  Once it happened when playing with my son, I got kicked but he was still playing the same match when I went in the other room to see if he did too.  I am pretty sure I was host that time too, not sure why everyone did not get disconnected unless XBL sees both of us as host.

Anyway, I ran line quality check and my upload consistency was 24%!  As mentioned in the auto uplink thread I changed auto uplink to manual (2048) and now I get ~90% upload consistency.

I have a minimum of  2 meg upload and my modem levels are in spec with no packet loss, why is this game needing so much bandwidth to host a game???

I have not played any more matches since doing this, just wanted to let everyone know where I was at.

[FurryNutz]

Did you have any GF rules set up or just using defaults? I was using defaults last nite.

We need to hook up and game some and do some testing.

[XS]

I am still using GF rules, I want to see if PT and manual uplink set to 2048 does anything for me first. My plan is to make one change at time and see how it goes.  I also would like to get more game time in to get more data so to speak.
I have port 3074 with priority of 30 and the other XBL ports set to 60 so my Xbox overall has priority over every thing.  If still having issues, I am going to disabled the other XBL ports in GF rules and only leave port 3074 with a GF rules and see how it goes.
Then I will try disabling all manual rules as you advised and see what happens.

Yeah we do to get some games in, I am almost done working all this OT so then maybe I will have some free time to play more than two games at time.

I also ran ping plotter last night for couple of minutes and it is definately more consistent then when I was not seeing these problem.

[FurryNutz]

I presume you are wired to the 4500 with the xboxes?

Ya, need to test some games out with and with out PT and GF.

[XS]

Yeah Furry I am wired on both Xbox's.  Anyway, I do see an improvement with lag when PT is enabled, not much but it is something, (see PF/PT thread for details).

I am really starting to think MW3 is just a broken game and there is nothing I can to do to fix the lag issues I see with this game.  I may just go back to Black Ops but I am going to give MW3 some more time and hope something will get fixed somehow-someway.

Anyway, so PT enabled does work for me so my next test I am running is to disable all manual GF rules so this way the router will determine what gets priority.  I will see how it goes! 

Also I was wondering if you are using manual GF rules why would you leave "automatic classification" checked?  Isn't this setting the priority twice so to speak and may screw things up?  I would think if you are using manual GF rules you should leave this unchecked?

[FurryNutz]

I replied.

Not really sure if Auto Classification is the same thing as setting a rule. I believe it has to do with how the GF interacts with the network and the packets coming and going. From my experiences, it's always been left ON. However you could test this out and see what works better for you though. Let us know.

[XS]

I found a review on the 4300 and this is what they said about auto classification:

"Automatic Classification feature enabled. Think of Automatic Classification as the lazy person's QoS, which automatically manages upstream bandwidth to give priority to applications that are time-sensitive. Here's D-Link's explanation of how Automatic Classification works:

"[Automatic Classification] uses a special intelligence engine to continuously classify applications as they pass through - it is not limited by the pre-defined applications. Those are there purely for convenience in setup. It will work for any application including VoIP. It also doesn't just prioritize UDP over TCP. There are 255 levels of classification that are based on a mix of several parameters such as protocol, port numbers, packet sizes, interframe timing, as well as several others."

The weightings used and the priority assigned are part of the product's "secret sauce", but you'll get a feel for how Automatic Classification works when I review my test results later."

Description from router help tab:
"Automatic Classification
    This option is enabled by default so that your router will automatically determine which programs should have network priority."

[FurryNutz]

Then maybe this could be turned off if using a manual GF rule.  
I would suspect that there could be a algorithm difference between the 4300 and 4500 as well. Depending on how they coded it and what they learned from the 4300 to improve on the 4500, there could be better improvements to the Auto Classification too that might warrant leaving it ON. Just a though. 

This would be a good test to see what works and doesn't.

[XS]

Yeah, I will give this try too, reading the info on auto classification, sounds like if you know how to set up QoS (GF) you should leave this unchecked. 
Too bad there is very little info on this router on the net.

[FurryNutz]

Agree, when I first got my 450o years back, I figured like everyone else does about there routers that all that was On out of the box. Then diving in to the router and tinkering with it, noticed that it's not quite set up for gaming or XBL. Ya, everything worked however Help and such was limited. I manged to find a couple of sites that referenced GF on the 4100 and 4300. I deduced that this would apply to the 4500 as well and it did. Got a better understanding over the years on how QoS and GF works and setting it setup well though.  

Just found one of the sites and it's still up, LOL: http://www.jerrykindall.com/gamefuel.html

Thanks for link Fur, yeah the more I read about GF, sounds like you don't need to set up manual rules unless there is a need for it.  I think Harry also stated this, Anyway, rarely anyone in my household is using the internet and if they are it's just surfing the web, Facebook, flash games, etc.

Also, manual GF rules supercede automatic classification which my screen shots also prove in the XBL port thread.  Only thing I am curious about is if the GF engine gets confused with auto classification checked and manual GF rules enabled.  I guess I will find out soon enough but I never had these issues with Bops and I am 90% sure its the gaming code IW is using screwing it up.

[FurryNutz]

Ok I'm going to try with No Auto Classification OFF and GF rules OFF and just PT. Just curious.

I looked and I have been using Manual GF rules AND Gaming(PF). That has been working over the past week for me.
