I recently installed Windows 8 Professional on my system, and this problem just keeps appearing. It didn't bother me at first, but now it gets really annoying restarting. Initially, my connection will be fine, but after a while (could be a couple hours), my internet doesn't work until I restart the computer. The thing is, some things still work, like watching live streams on Twitch.TV, and I don't think Skype calls drop either. Any ideas?
