I'd had my new laptop for a month and it had been working fine, when suddenly it said there was no internet connection (while I was using it). I checked the router, turned everything (laptop and router) on and off again but the laptop said there was no available connections. The other laptop was working fine. In desperation I refreshed the computer which (apart from taking ages), uninstalled my Kaspersky internet security and all of the Word software. It is a Windows 8 machine. I am a light user and don't download loads of stuff. It did the same thing yesterday, almost a month to the day after the last episode. Again, reinstallation of Word and Kaspersky was required. Does anyone have any ideas why this would keep happening?
