I have a Netgear WNR1000 ver-3, every once in a while I get disconnected from my wifi while using Chrome or Firefox, I then open Explorer and get a message saying I am disconnected from my network and a tab to fix connection problems, when I click on the tab, it goes through a series of fixes until it says a network cable is unplugged, but the internet then comes back up, is there anything I can do to stop this from happening, thanks
