Hi have applied firmware and all seems fixed! Thank you! How do I know that future firmware versions will include this fix?

@David-TP thank you - my ISP is Internode, I have not seen the Deco turn red whilst this is happening. I will take a look at the firmware and respond.

Model is brand new Deco M4R (it won't let me enter model number in field above!). Constant internet drop out via BOTH wifi and Ethernet connection to modem from both apple and windows devices....
