Hi everyone here.... I'm newbie here and I have a Linksys E4200v2 couple days ago. After set up everything seem be working fine, accept my iPhone 4s. I can do almost things on my iPhone, but when I tried streaming video, play youtube or streaming music from apps on the phone it stared buffering.... play..... and.... stop.... almost every 30s which never happen with my old Linksys E1000. And It happen with my wife's phone too. Even though my internet speed is not bad at all (Ping: 24 / Download 23Mbs / Upload 4Mbs). So I can guess that problem from the router. Then I swap the E4200v2 with the E1000, everything works fine again (it just a litle bit slower when loading at begin then play smooth). Please, anybody here can help me with that? I really appreciate.... Thank you very much!!!!
