Just purchased an iPhone and ever since I have had it, my Internet connection has had outages. I finally worked out that it is being caused by the iPhone, becuase if I disable the WiFi connection on the iPhone , the Internet on other devices is instantly restored. It only occurs sometimes, and only when the iPhone is connected using WiFi on the iPhone and not all the time. Also it doesn't just affect WiFi, but also knocks out the Internet of PCs connected to the router by cables. The router is one of the newer black spark ones, less than a year old. I do also have ipad and ipod connected at times, Android phones etc, and they have never done this to the network. Is my iPhone faulty as it shouldn't be doing this ? I noticed it mainly occurs when the iPhone is uploading to Dropbox, uploading images. However my android phone also uses Dropbox and doesn't cause this. Other people have had this type of problem on the Apple forums, but I can't see anyone has resolved it. I also tested it on a someone else's WiFi and it did the same thing, initially it was fine, but a few hours later the Internet connection was dead, and disconnecting the iPhone it started again. But as it is intermittent it would be very difficult to replicate the problem quickly.
