Windows 7

I have been running Comodo under the RC version with out any problems. I installed the RTM version. It installs ok but as soon as it goes to get updates for Comodo firewall it resets my Wireless connection to limited status. When I remove the firewall software my connection resumes to normal. The diagnostics for the firewall are run and it supposedly fixes the problem but the firewall still shows as not working. Is there something I can check to resolve this problem with W7?
