Vista Network Connection and Upload problems

Hi all,
I think this board might be my only hope.

I've been using Vista Home Premium x64 SP1 for a few months now and connecting to my wifi is a definite no no, but that is probably due to the fact that I use a crappy wifi card in my desktop that is not configured for use with Vista.

No biggy, I just use the integrated ethernet plug on the motherboard and it works fine.
Until.

Every time I try to upload something larger than lets say 10mb it has a fit and goe into the now well-known Local Only mode.
It also does this sometimes when I visit Facebook (weird I know) or when the PC goes into sleep mode and comes back online after I wake it.
But mostly I get the upload problem.
Downloading is fine.
I checked and upgraded all the necessary drivers, have all the vista updates and am stuck using my laptop (running XP Pro) for the uploading part of my daily work.

I use Bitdefender as an AV and Firewall.

thanks for any advice.
Willy

Hi Willy and Welcome to Vistax64.com!

Try uninstalling Bitdefender then restart and try some tests to see if its working again, This Tutorial might be helpful too...
