I went out and bought a newer faster router with a bigger processor and buffer and have docsis 3,1 The motorola 8702 my wifi range is much better and faster
a true wifi hack is all come with Junk wall warts .I put a12 v linear power supply. On it ,it improved the wifi signal ,better picture and music streaming better.
i initially bought from little green computer it’s good up to 8 amps most 12 v routers draw around 4 amp ,imo $$ well spent.
