Internet Randomly Cuts Out And Random Lag Spikes Only Desktop

Problem: This problem has been going on for a long time thought I would ask you lovely people before i just gave up on my adapter or something like that.

While I download things it randomly drops to very low (3kbs) or randomly just stops completely, usually download is around 300kb/s+ and this only happens on my (homebuild) desktop, every other laptop/computer works fine. Also when playing online games (ex swtor) random lag spikes that last for minutes+ while the internet works just fine in browser. Whenever a problem occurs it always is fine just loading web pages, just downloads/online has problems.

I have tried moving my computer around the house, trying wireless and lan and today i installed windows 7 64bit (was 32bit) hoping for a difference and still nothing. After this fresh install every driver is fully up to date. As the adapter only has wireless it would seem the problem also occurs with mobo (since plugged in for lan) Some bad connection in the case?
edit Just open up the case everything is connected unless something is just broken

The router is also a D-Link while the modem is a Motorola (two around the house)

Hardware:
Os: Windows 7 Ultimate 64-bit
CPU: Intel i5 2500K
Ram: 8GB
Mobo: ASUS
GPU: Radeon 6870
Adapter: D-Link DWA-552 XtremeN Desktop Adapter

I am unsure of what the problem is, help or advice would be greatly appreciated, thank you.

I'd like to try to reset your TCPIP stack and based on having win7 this is where to start: ( http://support.microsoft.com/kb/299357 )

The reset command is available in the IP context of the NetShell utility. Follow these steps to use the reset command to reset TCP/IP manually:
To open a command prompt, click Start and then type CMD in the Search programs and files.
Right-click CMD.exe icon in Programs and choose Run as administrator.
When the User Account Control box pop up, click Yes.
At the command prompt, copy and paste (or type) the following command and then press ENTER:
netsh int ip reset c:\resetlog.txt
Note If you do not want to specify a directory path for the log file, use the following command:
netsh int ip reset resetlog.txt
Reboot the computer.

Also do your adapters have any bridging configured or other protocols aside from IPv4 or IPv6? Depending on how your downloading things it sounds like TCP is working but any UDP type packets is where the trouble is?

using latest drivers? have you tried older drivers?

Also you have an Atheros AR5416 chipset, you can try swapping the dlink drivers for the specific chipset ones and use the windows wireless zero config to manage wireless networks.

Good luck

I reset TCPIP using the link and that had no effect.

I do not believe i have anything like that configured, i did have a proxy set up for US netflix at a point but i got rid of that.

I also found an old wireless adapter and tried that, i still get internet connection but the problem still persists. Things like youtube videos load perfectly fine yet downloads (ex driver updates) go at horrendously slow speeds and get a network time out before it even gets the 20 or so megs done. Will try and get a different computer to download the drivers so i can try that, but this is what happened so far.
