I have a cable LAN at home two laptops and a media center with W 8.1. I have a recent problem with the last one. Copying large files between the laptops is ok (2.74GB in 56 seconds). But copying something from the media center - about 1mb/s. I tried different sockets in my router - everything the same.
Internet connection speed tests - laptops download around 50-60 Mbps upload 5-7. Media center download 9 Mbps upload 5-7 (similar to laptops).
What should I do to fix it?
