Was using a technicolor modem/router was having nothing but wifi issues with it but was getting my Ult 300 speeds, just bought my own router a TP-LINK Archer C7 AC1750, and using a SB6183 modem have no wifi issues at all but only getting Ult 200 speeds my pc is directly connected. Provider Time Warner Cable.
Not to familiar with routers maybe I need to change a setting or something?
