Sorry for bumping an old thread but I just recently started having this problem and so far, this is the only topic I could locate on Google. Long story short, I have a HTPC connected to a 3D projector. I can not connect to the internet (pci wifi card) at 1280 x 720p or 1280 x 800 resolution. 1280 x 720p @ 120hz is the resolution needed to play 3D and 1280 x 800 is the native resolution.
I've tried installing and rolling back the Nvidia drivers
and the only way I can get around this issue is if I change my desktop resolution to 1680 x 1050 (@60hz). I can not for the life of me understand what is going on. I've reinstalled Windows 7 x64 twice and this issue appears as as soon as I install the Nvidia drivers for the GTX 460 card. Internet connection is PERFECT when the stock VGA driver
is used. But after installing the GTX460 drivers, why would I be able to connect to my wireless router, but the link to the internet is broken? Or, when I look at the network properties, it'll show that i'm connected to the internet, but when I open a Internet Explorer, it just sits there. No sooner do I change the resolution from 1280 x 800 (or 720) to 1680 x 1050 does the wifi connect to the internet.
I'm only able to use the last version (v260.99) because if I upgrade to v266.58 or the v267 beta, my 3D becomes unstable when I use Total Media Theater 5 or Power DVD 10. This is a known bug and Nvidia has not fixed it - they actually exacerbated it when they updated the driver from 260 to 266. http://www.arcsoft.com/forum/forum_p...een-in-3d-mode
