I just bought the Deco M5 last friday and managed to setup the device. Unfortunately, encounter the issue which is the router doesn't allow Astro Decoder to connect via WiFi and Xiaomi camera as well. Astro and Xiaomi able to find the SSID, unfortunately that while enter the correct password for the SSID. it won't be allow to connect it and giving the IP address. Then both device will be keep appear to enter the WiFi. End up, the Deco can only become AP instead of full router. Basically, the deco M5 having so much problem with your software and issue. It need to be quickly resolve, likewise better don't sell it to market. I will be go more forum to complain about TP-LInk device which having so much problem and the helpdesk unable to resolve and push the issue to other device which is so unprofessional.
