I bought a Lenovo Ideapad Y480 pre loaded with Windows 8 last month and I've been facing issues with the Wifi connectivity. My home Wifi gets connected directly when I turn my laptop on. But it gets disconnected in not more than about 20 minutes. The Wifi network is still available in the Networks bar, but if I click connect it says there are problems in connecting to the network. Troubleshooting didn't help. I turn Airplane mode on and again turn it off, Wifi works again. Now this is annoying to do everytime and my computer is supposed to work properly! Anyone with a solution?
