iOS 6 / 6.1 Wi-Fi problem .
Hi everyone !
i have a very annoying probleme with my iphone 4 under ios 6.1 now , when 6.0 first came out i updated and had a problem with wifi : i can succesfully connect but when i start watching a video or downloading something or even browsing a heavy website, the wifi connection goes off and get back again after few seconds. i have a Sagem FAST3304-V2 router and i tried nearly everything i found on the web ( restore , DNS , security settings on the router ), but it seems no one is having the exact same problem as me. the 6.0.1 or 6.1 update didnt fix it ! PLEASE HELP !
iPhone 4, iOS 6.1
