Very slow internet after upgrade to 64bit

Hi, I just upgraded from Win 10 32 to Win 10 64 bit and my internet connection is very slow, about 20/30 kb/s. It was a fresh install, deleted everything and reinstalled from scratch. I have looked on the forums and cant find a solution that works, I've checked the network adapter drivers for my wireless and they're up to date. I've troubleshooted the problem and they said something was wrong with the network configuration which was solved, but still no change in the internet speed. I've got broadband and should be downloading at hundreds of kb/s..any ideas would be gratefully appreciated.
thanks,
NIck

OK, this morning I tried my internet connection again, downloading a game via an installer. started off very fast for the first few seconds about 50Mb/s then dropped to about 5 Mb/s and then eventually dropped back down to where it was yesterday at about 0.25 Mb/s. If anyone has an idea as to what the problem might be I'd be very grateful.
thanks,

Two things come to my mind, one is that you can't upgrade/change from 32-bit to 64-bit [or from 64-bit to 32-bit], has to be a clean install, and that brings up the second thing which is getting 64-bit drivers installed for devices.

Hi Berton, thanks for your reply, yep I did a clean install and reinstalled drivers, but still have a slow connection. Have tried Microsoft support aswell. Any other ideas appreciated.
