My lenovo was working fine until after last wed overnight updates. I can connect to Internet in safe mode and ping etc. I can't connect in regular mode. And at same time this problem started I got error message about java. I reinstalled java 32 and 64. Still not connecting. Geek squad ran check on my laptop after problem started and shows no virus and other than somehow a software issue since updates blocking connectivity, it's in great shape. Any advice?
