Thanks for the quick reply;
Toshiba C655-5049 laptop.
Board: TOSHIBA Portable PC Base Board Version
Bus Clock: 800 megahertz
BIOS: INSYDE 1.20 04/27/2010
It came pre-installed with the laptop, with 64bit Win 7. Device manager says PCI bus 3.
The driver for it on the Toshiba support site is from '09, and I've found a couple from '10. I keep finding new drivers as I try to fix my connectivity problem, so I figured I should just ask for help and maybe someone could direct me to the absolute latest.
