Internet speeds dropped after move from 32 to 64 bit Windows 7

Message 1 of 7

Any advice on restoring my speeds, 25/25 package??  I switched one system to 64 bit Windows 7 to take advantage of a RAM upgrade. Now my speeds stink !!  2-5Mbps down or up from the 23-26Mbps I was getting on this same computer in 32 bit version. Ran I.E. in administrator mode, put VZ site in trusted zone and used Speed Test & Optimizer from VZ site, says settings have been optimized but no change.  Thanks

I think I got it solved. Rolled back then re-downloaded the network driver from Nvidia. Thanks for your help!  Ahhh, happiness again

I've tried running the optimizer, restarting the browser, restarting the system and letting it reset the Windows setting several times in various configurations. It was a simple couple of clicks to get it working in 32 bit mode.
