Been have serious stability issues with the deco (I have 2 of them).
I confirmed the problem is the deco and not my modem by connecting directly to the modem each time it happens, I usually need to turn off the main deco and turn in to make it work normally again, occasionally I need to reboot my modem to fix it, but the problem is not my modem since it's working perfectly fine wired or wifi but rebooting it sometimes fix the issue with my deco.
Tried switching ports and cables (cat6 or cat7) but it's still doing it sometimes. The LED on the deco always stays green, I just don't have an internet connection wifi or wired.
