Did a firmware update around the first of Oct but I don't know the specific numbers. The router is the same as we have been using. Hardware version A1?. A few things I see that may tell you something, The audio stream is on on both the iPad and iPhone, the bit rate is 2190 on the phine, Type H264, motion detection and sound detection are both enabled, extender mode repeater settings, enable repeater mode is on dlink-3F42. Hope this is enough info
