Make, model of the router. Also, call the supplier/maker of the router and ask why there.
When I connect wirelessly to my router I am able to pull my full circuit of 25mb down and 5up. When I plug into my xfinity router directly with a cable, it seems like im getting capped at 5x5. I thought it was a problem with my cable but upon switching it out I got the same 5x5 speed with nobody else on the lan. I could not find any settings on my router that would be limiting my wired connection. Any thoughts?
