I have a x50 and 3 x20s for my 2700sqft house. My internet comes in the front living room to the x50 and it is hard wired into a x20 into my bedroom. I have one x20 in the office on the opposite wall of the bedroom (shared a bathroom) with the wall, and another across the hall from the bedroom. However, my office internet where I work from home keeps dropping internet during the work day and the bedroom below the office and the down stairs do not receive signal at all even thought the "WiFi" signal is full bars. Any help would be greatly appreciated. Or if someone would point me in the best direction to cover my home with WiFi, we currently get 400mbps up and down. Thanks
