Windows 7: Internet Disconnects

So heres the deal.
Ive recently upgraded from windows XP 32 bit to Windows 7 64bit, this ofcourse means Ive formatted my harddrives and made a clean install.
But now Ive realised, that whenever I try to download a large file which takes several minutes, my computer will disconnect from the router and I have to let windows do its thing and it says its "Resetting Network card" After this I have to reboot the PC and yet again let windows do its thing where it tells me to let it reactivate my network card. When Ive done this Ill be connected to the internet again. Ive tried to let my PC run for several hours just to make sure its not random dc's but within 5 mins of me starting a download it dc's. I can browse around just fine and have tried countless of different solutions around the web and none have helped so far. Now I beg you to give me Every single possible solution that you guys can think of. Keep in mind that I have another PC running vista connected to the router and that one works just fine, and I never had this problem on XP.
Also please keep in mind that Im not all that techie when it comes to router settings and such, so keep it simple for the sake of my brain not overheating!



Thanks in advance.

Sounds like a network driver problem but I don't see any network driver downloads fro Windows 7 X86 or X64 on the ASUS site for the Gigabit network device.

As a test, remove the router from the setup and connect directly to the broadband modem. Try a download and see what happens. If it fails the same way then the router is definitely involved. If it doesn't fail then try swapping the port and cable the router is connected to with the one currently in use by the Vista computer then try the test again.

If it works then it is either the Ethernet cable or some problem with that specific port on the router. If it doesn't make any difference, then try deleting the Gigabit network device from Device Manager as follows:

Press WinKey+R to open a Run box.
Type devmgmt.msc and press Enter
Expand Network Adapters
Right click on the Gigabit device and select Uninstall
Reboot and wait while Windows 7 rediscovers the device and reloads the driver, see if that helps.

Still doesnt work, other PC's work just fine but mine disconnects whatever I try.
The last option you gave me, the reinstall of network card driver thing, had the internet stay on for a longer time. It might have been a coincidence but it was on for longer, dont know why it would though or if it matters. It did disconnect in the end though.
Also as I mentioned, this problem first occured After I installed windows 7, could there be any settings that I have to change which makes the internet work the exact same way it did on XP? Just thought that could make a difference of some sort if you knew.

Again, any help is welcome!

Did you try removing the router and connecting directly to the modem?
