@Solla-topee Failed everytime after 5% and LED lights are yellow, red, green, blue and then again red and yellow and keep stuck on yellow. My Deco is dead after voltage fluctuation i think.

I tried to install firmware by using HTTP Recovery Mode but failed everytime. Maybe my Deco M4 is dead after voltage fluctuation. I tried after changing adapter but nothing happend.

@aminulzx You can update to 1.4.0 latest firmware.

@Solla-topee Okay i will and will update you after that.

@Solla-topee I mean RJ45 Connectors.

@Solla-topee I'm using CAT6 cable since 4-5 years and now suddenly speed changed from 1000 Mbps to 100 Mbps on Deco M4. Do i need to change cable or do i need to change ethernet clips?
