Since you seem to need only one network adapter I will focus
on that reduction-of-variables method to end up with only
one working and getting rid of clutter from the others'
drivers and software.

Delete the wifi card from Network properties and/or
uninstall the driver from add/remove programs. Next power
cycle the router. If it still doesn't work, reboot the
computer then check for the other (intel) network adapter in
network properties, and if it isn't there check device
manager to see if it's disabled or has a question mark as an
unknown device. If it is unknown, install a driver for it.

Follow the above procedure for this card too or instead. If
you don't need two networking adapters (which it would seem
you do not), I would pull out this one and try the integral
one, unless the new card is Gigabit capable then disable the
integrated one in device manager, or even better to disable
it in the bios if that is possible... and uninstall the
driver for it as well, for either card you are no longer
using as well as any monitoring software if any were
installed.

After you have done all the above, if it still doesn't work
then open up a command prompt (type "CMD" from the
Start->Run menu option), then type
"ipconfig /all > C:\output.txt"
which will make that output.txt file in the root of your C:
partition, so you can easily copy and paste that text in a
reply here.
