Hi there, I have had the Deco X55's for a while (three of them) that came as a 'Ax3000 Whole Mesh Wi-Fi 6 System' pakage and all has been well up to now. 

Today I couldnt connect at all so I unpluged the one that is linked to the router, rebooted the router numerous times but no joy. 

When they were all working fine a while back I disabled the light on them as it was too bright but now I can't see what light they are giving out so can't get it to flash blue to re-set it up.

The Deco app just keeps saying can't find Deco so I have deleted the network to try and start again. It's plugged in and connected to the router but says can't find it.

Seems like the main one I had connected has died? Any advice?
