Ok so I installed OA 5 PRO (the one without the antivirus) on my win7 64bit machine. Allowed it to do the file scan wizard, configured it via the file scan wizard, rebooted my pc. Now it works fine when I browse the web but eventually after few minutes I get NO INTERNET display on my Win7 box...basically the network is fine but the net is down. When I shut off OA it doesn't help, I have to shut off OA and reboot my linksys (running tomato firmware). Any news on what might be causing this? Is it the tomato firmware?
