Unusually slow internet problems

I'm rather experienced with computers and know its nothing of the obvious.

I recently built a new rig, my motherboard is the asus striker II extreme which has dual gigabit lan and the ai teaming technology. I did a fresh install of vista ultimate x86 on the new hard drive, everything running fine and i was achieving maximum internet speed. However after running windows update i noticed the download speed is terrible, approximately 25kb/s on average and i am capable of speeds of up to 650kb/s. After updating all my drivers, running the computer in safe mode, turning off all security and eventually resorting to using a download accelerator my problem persisted. So i thought it must be the update, i wiped the hard drive clean and did a fresh install of vista again, however, before running windows update my speed had actually worsened to around 6kb/s and around 50 or so using a download accelerator.

I had the same OS on my previous setup, same router too, and it worked just fine. I have tried a connection using the wireless pci-e card i had on my previous setup and the dual rj45 cable to my router and even tried it using just one cable. I really can't get my head around whats going on. If anyone has any ideas or experience with this problem, thanks in advance.

UPDATE - Problem solved! Intels annoying pushpin engineering once again has proven itself to be a ridiculous method of installation. Reapplied some arctic silver 5 and remounted the pins after much effort bending pins into place. Internet speeds are once again optimal!

I am having exactly the same problem. Everything is fast EXCEPT http file downloads. Searching all the threads I can not find an answer. I can't find anything on google. I can see alot of people are having the problem. Viewing peoples post I can safely say it is not the mobo, the browser, CPU, router. It does appear to be happening mostly on new builds.

Has anyone.....anyone have a clue to the problem? Help 8(
