@MGee1 the most likely cause of wifi connectivity late at night is increased interference from other electrical equipment and most likely from neighbours' networks. Streaming video is particularly vulnerable to interference as while the stream can cope with some loss of data go above that level the stream buffers or stops all together the so called digital cliff .Ethernet cables totally avoid this problem.
If your devices are relatively far from the hub they are likely to be relying on the slower but longer range 2.4GHz band which only has room for 3 or at most 4 networks before interference starts. A lot of other wireless kit like wireless speakers, head phones etc use the same frequencies which causes more issues. The so,ution is to improve your home's network so devices can use the 5GHz band which has more space and shorter range so interference is less of an issue. Sky offer a bundle called WiFi Max which can supply up to 3 pods which can help but a lot depends on the layout and type of construction of your home. The closer you are to your neighbours the worse the issue which makes flats a particukar problem.
