@G_Arora hey thanks. But no luck for me. I tried 2-3 times with reset and the wifi gets disconnected for devices. Finally 2 days back, I used the recovery tool to flash 1.4.x version and it is stable...

@G_Arora tried this way. But still having issues

Same here. It was working fine before the update. I tried factory reset but no luck so far. I had only one deco unit. Here the wifi connection is randomly getting disconnected and I had to switch off...
