Im ditching my netgear extender and looking to use TP Link.

Im in a long city flat and having a lot of trouble getting reception in my bedroom at the opposite end of my house from the router.

With my netgear extender, i have to keep it in my hallway to get service from the router and then push it into my bedroom.

Im trying to figure out of i should get 2 re603x's, one for my hallway and one for my bedroom, or if i should just try one 700x in my bedroom.

Any suggestions?
