Hi, troubleshoot such problems via 3 major sources, namely the phone, the network (router end) and the air purifier. a) The Phone i) Check to see if the phone is connected to your Home / Office network ii) Check to see if certain privileges may be disabled for the Mi Home APP on your phone settings b) The Network (Router End) i) While Mi air purifier supports most routers, but it only supports 2.4GHz WiFi, not 5GHz WiFi ii) The WiFi encryption must be WPA or WPA2 iii) Failure to support the needs of the page authenticated network, for example: CMCC, ChinaUnicom other public networks; iv) Some routers may not be able to connect to it, identified router models with issues are : TP-LINK WDR6300 (unless set up to use only 802.11b), TP-LINK WR880N (shutting down WMM may resolves the issue) v) Routers with advanced features set-up, like hidden SSID, disabled QOS,non DHCP settings where you need to set a static IP manually, or router settings that requires MAC address binding no connect
vi) Close all router wireless control for blacklists; vii) Company intranet which had disabled port 80 or UDP may lead to it not working properly with the air purifier; viii) Does not work if you are connecting to portable USB routers; c) The Air Purifier Air Purifier may have been previously configured to connect to another network, or is currently connected to other networks, please reset the Air Purifier WiFi settings by pressing the Operating Mode Choice and Switching of Indicator button simultaneously and holding them for 5 seconds. After you hear the beep sound, the WiFi settings has been reset.
