GA-F2A78M-D3H Network problems-New build

[lemure]

Hi,I'm having network problems with my new desktop computer.Internet speed is extremely slow and while I've tried quite a few things,I can't seem to get it to work properly.
Now my router is a D-Link DSL-2750B rev.B1,latest firmware installed.I' ve also installed the latest mboard LAN drivers from the Gigabyte website.The internet connection itself works fine,as I've tested it by connecting the router cable to another computer,which works fine as it did with my older computer.Wi-fi connection also works perfectly,measured through a laptop.
My mboard is the GA-F2A78M-D3H with an Amd processor.
I've already tried reinstalling drivers,turning off the firewall and antivirus yet internet speed doesn't even come close to its' potential.
I'm using Win 7 64bit.
Any suggestions??

Well if it works fine in your other devices I would have to say it is the board. Now you can send it in for RMA or you can get a cheap pci card that will handle you internet.
I have had this problem I just got a stand alone card I figured it wasn't worth sending it in more in shipping than the card cost me.
