Hi, I'm running Windows 8 on a Lenovo Ideapad. After an indeterminate amount of time I can no longer browse through any browser, or update any programs (even though I am still connected to my wireless router). When I restart my laptop, the internet is working again and so on. My smartphone can still browse the internet when it ceases to work on my laptop. I have already done a Refresh, but the problem persists, can anybody help me?
