I like this router looking awesome, and it is fast, using my new iPhone, it is almost twice as fast than my previously AC1600 router, however this router constantly have connection issue with my 'older' devices, including Mac Air, Sonos, Philips Hue bridge, etc. My iPhone 6 couldn't make the connection at all, the Wifi on my phone was showing connected, but there is no internet, the router still display the phone as offline. Sometime after a few rounds of reboot, this can be magically fixed, but everything will be disconnect after another power off/outrage, all the 'older' devices will lost their connection again and won't be able to connect automatically. I'm using the latest firmware and tried to disable AI security guard, that makes no difference. I decided to return it, as it was causing too much of my time and trouble with connecting all the devices, it wasted a lot of my time. Also this router doesn't come with the power adaptor suitable for use in Australia.
