When the Guy from my ISP came by to upgrade our router and such after switching, he told me my house has “old wiring” making it not suitable for 50 mbps speed. I then got told that 20 is max I can get, I’m not very knowledgeable when it comes to this type of stuff, so I didn’t think much of it until I realized when I searched up the issue there was nothing I could find relating to my problem. I thought someone could give me an explanation on this? Thanks y’all.
