I am using the router provided by PTCL (Sagemcom F@st 1704) for SmartTv and Broadband. I have placed it on the ground floor and I have connected an old TP Link WR740N router to extend the Wifi range but I am still only getting a very weak signal in some places on the first floor. What is the best way to extend the range of WiFi signal without using any extra cables?
1) Range Extender
2) Should I get an 8dbi or 9dbi antenna instead of the 5dbi one ?
Additionally is there any way to use my Tp Link WR740N to extend the range without any wired connection with the Sagemcom 1704 router.
