Hello. One night there was a short power interruption in the area. After that we can't connect to the internet so I check the Deco M4 WIFI extender.

It was now displaying a steady yellow. I tried to reset but it is not working. I check on this forum

but it is not working for me. Also tried this one https://community.tp-link.com/en/home/stories/detail/672

but i got no luck. I can't get into the recovery mode. It only displays solid yellow light. Hope anyone here can help.
