Hi guys -- I just had my 6S+ replaced at the Genius Bar. My phone did the blue screen of death and died. Long story short, I bring home the new one to set it up as a new device (I never do setup from backup) -- thing is, the AppStore download speed is non existent when I'm connected to my wifi. Blazing fast on LTE though. I did a full reset. No luck there same issue. I did a DFU reset. No luck there either. I did a full Airport 802.11ac reset. No luck also. Went back to the store, they swapped the phone again, thinking it could be hardware related. Same issue upon returning home with this second replacement. I read threads with people complaining of this very issue on 9.1 -- talking about tinkering DNS settings with their ISP. I just don't understand what the problem is. Anyone experiencing the same thing?
