Hi guys, I cant say I've ever had a problem like this before. Yesterday my laptop (win 7), my wife's laptop (win 10), a 3rd windows 10 laptop and her HTC android phone all became unable to receive typical internet speeds. Our internet connection is typically around 25 mbps and they are all receiving around 0.5 mbps. I have at least 2 devices that are running completely normally having done speed tests on both. Those are my iphone 5 and a PS4.
All our devices are using wifi to connect to the router and the router is a modern SKY (UK tv + broadband company) router.
