Top critical review
Most awful repeater I ever used, first return item in Amazon.
3 July 2019
Setup require download Mihome app. And take much longer than average. Although it's a brand new device, the app keep asking reset the device and try it again.
Finally it works. But I have two serious issues:
1. The connection is not stable. I tested by long ping my local dns server and google.com; it lost connection for 1-2 seconds every 20-30 seconds. At the same time, long ping without repeater is very stable.
2. I tried upgrade firmware of the repeater, but after tried 8-9 times, I realised it's a bug and this device cant upgrade firmware at all. I google this issue and found all Xiaomi repeater has this issue since 2016.
