A few months ago, my family bought themselves a Synology NAS, and since we have purchased it, I could not find a way to get this thing to do transfers at a decent speed over our network. It is wired directly into my modem/router combo from Bell(ISP), which my dad has unfortunately locked down for no apparent reason, but if I can fix this problem, he'd probably let me in to do so. My PC has a direct wired connection to the router, and achieves speeds around 4.5 MBPs down/ 1 MBPs up. Our internet speeds are not too far off from this, around 2.75 down, 0.3 up. When I directly wire my PC to the NAS, I can achieve speeds of around 80 MBPs to my SSD, which leads me to believe there is some sort of networking error in the way we have things set up.
This NAS will be mostly accessed by wireless devices throughout the house (PLEX server), so getting a switch isn't an option, since my PC is the only one in the house that has an ethernet connection. Any ideas on what I can do?
