My Computer is a Windows 8.1 Desktop and I have a D-Link DIR-868L Router and an Arris TM822G Router. We have the 100 mbps plan from Optimum and while all the other wirelesss devices get it with no problem, my computer struggles to hit 1 mbps. There would only be one time out of the day where it gets it but after that it goes back to single digits. I've had other laptops connected with a wire and they hit 100 mbps so I know this is a computer issue. I want to say it has to do with an energy saving option but I have no clue. I've had an optimum guy come give me two new routers in the last 2 months and one new modem. The newest one I received was last week. Can someone help me? Here is my internet speeds for the month
