For the past few months, my computer has not able to access the wireless connection at home while other computers can. It started working temporarily and then stopped after a week. I then reverted to connecting directly into the router but a few days ago, it suddenly stopped and I only get connected during the the period that's roughly around 12 am to 12pm. I manually put in the internet settings, reset the router and i recently reset the winsock settings.The previous time it happened, I went so far as re installing windows. Nothing seems to work. My computer is a Lenovo G530 and the OS is Windows7 Enterprise. Please indicate the best course of action since I start school soon and I will need a home network connection.

Windows 7 Enterprise on that model of laptop? Where did you get it and how is it activated? If it's the evaluation version it may be expired. If it's pirated, well... If it's a legit version (activated via a corporate volume license or KMS server) I'd say something on your mainboard's gone south, probably from heat.
