XIAOMI ROUTER

I got this router yesterday. It was working just fine until this morning when I woke it stopped working. I tried restarting it, calling the internet provider, resetting the modem, Nothing worked. I bought this from Aliexpress with seller (iTechnology Life). I will write my updates regarding the dispute case. If anyone watching this video that knowledgeable in resolving this problem please write your comments down below. PS: I am uploading this video using LAN connection
