Well my apartment building has free wifi but the signal is always horrible at best and makes doing anything online a hassle. I need an app or a tweak in which I can connect to my apartment building's wifi using my iPhone as sort of a hotspot to increase the signal in my apartment. I have a monthly family share plan through AT&T so I have a personal hotspot I can use on my 5s already but I don't wanna use unnecessary data, just need to enhance the signal of the wifi I already have.
