Suddenly the wireless connection in my home office won't work at all. Works in the other rooms in my house, but even bringing a laptop into the office wipes out wireless on that, too. Restarted computer, restarted router, restarted modem. No go. The only thing different is that we just used Roku for the first time in probably a year....and I think we changed routers in between time, so it may never have been used on the Netgear router. The room the Roku is in is located just above the office. Office desktop computer only recognizes network on ethernet, but the laptops are working fine wireless in the rest of the house. Is this coincidence? Not a computer guru and no idea what to do next! Help!
