Vista x64 Disconnects and High Latency(Lag)

[Lovecraftian]

I've been scouring the net for the past two days looking for various solutions and none seem to have really helped.

First off, my setup, which I just put together a few days ago:

MSI P45NEO3 FR Intel p45 Mobo express chipset based
Intel Core 2 Quad 8200 @ 2.33ghz
4gigs of DDR2 1066mhz ram
Using Onboard Soundblaster Audigy SE (I have an older Sound Blaster Audigy ZS 2 gamer, but was running kind of funky, so I took it out)
Xfx Geforce 9800 GT 512mb DDR3 video card
Case (if it matters) Raidmax X-Force w/side 230mm fan
Thermaltake Purepower 600w PSU
Seagate Barracuda ST3500320AS 500gb Sata2/300 7200rpm 32mb HD
D-Link Wireless G Desktop Adapter WDA-1320
old Liteon DVD drive from my old desktop

Okay now for my common, yet hard to solve, problem.

I can connect to the internet fine, with firefox or IE, I can download at 400k+/sec , I've done speedtests and get quite fine download/upload speeds. But whenever I try to play games like CoD4 multiplayer, or Age of Conan, or even activate Two Worlds over the internet, I get one of two things:

My wireless disconnects, I usually alt tab to find it with the infamous red x on it and that it's disconnected.

On Age of Conan I fiddled with settings, called Microsoft (removed some KB files) and I got it to connect only to experience 4800-6000+/ms lag/latency. Which is obviously quite unacceptable to play any online game.

I CAN connect to ventrilo (I've heard some people can't with vista x64), as I'm explaining/asking a friend about this. I've seen other people on, for example, the Age of Conan forum that run Vista x64 and can run AoC fine.

I've got vista x64 drivers for everything, tried multiple different ones for my wirelss adapter. Tried the autotuning disable, tried the WLAN autoconfig disable from this site:
[H]ard|Forum - View Single Post - Vista + Wireless + 60 sec lag spikes = SOLVED

I've tried turning off the QOS Packet Scheduler, the File and Printer Sharing for Microsoft Networks, IPv6, the two Linklayer settings, and nothing works still.

Tried WLAN optimizer and Vista anti-lag programs, to no avail.

Called Microsoft and was on with them for an hour with their tech support and they had no clue. Yet from searching the internet, obviously there's some kind of problem.

I really just have no idea, and I'm about to almost give up and go for XP SP3 if this doesn't work. Which sucks, because as bad as I've heard Vista to be, I don't actually mind it, even if that sounds bad to most people. I just want it to work =\.

Hmmm.. It seems you tried all the Major Solutions and Tweakes Let me give a suggestion,

Maybe Your Router is Fried ? Not sure But is it like you have to keep rebooting your router for the Internet connection to be Established again? or You just have to reconnect by clicking the Wireless Icon on your taskbar?

And Also I used to have lagg and Spikes playing a Game called "GunZ" But I Used a Program called "Advanced SystemCare V3" It's a good program quite actually it comes with some extra programs too This program is usually main is to Clean your Computer Privacy Sweeps and Registry Problems Junk Files and Etc, It can also Optimize Your computer due to how you use your computer for instance it has options like, Daily, Basic, Entertainment User (I will Suggest this option), Top Performance ( Recommend if your computer is old and your playing games like Call of DUty 4 and Etc This is the Best Option) and Etc. But back to the main solution if you click on Advanced SystemCare V3 THE "Utilities" Option it gives a programs that can help your computer the program I wan't you to pay attention to is "Firefox TCP Optimizer" if oyu click that it can help stop yoiur wireless spikes or lagg and its very easy to use you can Just find out your Internet Minumum speed select the drop down list from it and it will do all the work optimizing your internet to go Way faster and stop lagg/spike.

So Yeah Try those Suggestions and Reply back
