I got it from the same link you posted for me. It was just underneath the card with the -VA2 designation.
If you think it will make a difference I can try the -VA2 drivers.
No probably not, so let that thought go.
Couple things to try
First delete any existing wireless profiles. Open network and sharing center, choose manage wireless connection from left column, select and delete any profiles and then use the add+ utility to add a new profile manually.
If that doesn't work, try resetting router to factory defaults by employing the recessed reset button on the back, this should remove any previously configured custom settings, which is good and bad, good in that wireless encryption may be an issue and this step should eliminate that as a potential issue. Bad in that you may need to add back your username and password to the WAN side if you are using a PPPoE connection like ATT and of course other customization like the admin password.
If still no joy, then a full network reboot that includes your ISP's provided device and router.
Bring the wired adapter back into the equation, and post an ipconfig /all with results for that adapter included, it is presently showing as media state disconnected.
You can also try manually assigning static ip address values for either or both network cards in the IPv4 properties and you may also want to uncheck IPv6 for both while you are in there, just to take that out of the equation.
