NIS 2010 Wireless Connectivity Problem

I have been having wireless connectivity issues since I installed NIS 2010. Several times a day I loose my connection to the router and the only way to fix it is to reboot.  I uninstalled NIS 2010, used the NRT, and reinstalled.  It did not fix the problem.  I have Vista SP2 64 bit. Is anybody else having similar problems?  This did not happen with NIS09.
