Guys I have a GT-AC5300 and I have been trying to use the smart connect but am fighting a problem that part of the house has a very low signal. I may just have a bad 2.4 gig radio as my 3200 has great signal. I am trying to use the smart connect as my 77 year old father in law and 74 year old mother in law are on it and are both from Vietnam so I need to router to do the work. My question is does anyone know of a way to find out which of the 8 antennas are used for the 2.4 Gig band. If I can find that out then I can put a couple of high gain antennas in the right place and should have good coverage in the whole house.
