We have moved houses recently and previously we had similar maybe 1-2mbps differences when we were on virgin media now we are on sky and have fibre pro but he is getting speeds of 40 mbps and iam stuck at 5 the uploads on mine are slightly higher than his but apart from that my downloads are so much lower, my laptop is pretty new i bought it 1 and half years ago and his is about the same age. My laptop used to get much higher speeds than my phone with virgin about 10mbps but now i get like 5x lower when my phone gets 25mbps i need to find out why my laptop has such low speeds i dont have any viruses i have malwarebytes pro and have ran a scan very recently i mainly just play league on laptop and browse the net
