I bought a 3 ud bundle of Deco XE75, but I´m still unsatisfied with its performance. I have a house with 4 floors, brick and mortar built. The carrier fiber (DIGI) comes into the house on my level 2, through . From 2 to 3rd and 4rd floor goes through a CAT6. I follow up your Android app, but I experience all sort of situations:

• Wifi: left active on my carrier router (Zyxel EX3301-TO) and connect to one XE75 by robust CAT6. Same SSID on Carrier route than on Deco
• Wifi: left switched off on carrier router but only left Wifi active on Deco (same SSID), but left connected to the carrier route with a CAT6 (changed a number of times the physical cable for different ones, with same results)

on all cases the wifi stars to downgrade and can keep with app optimisation tool, until the point I loose wifi, with red lights on them.

You might imagine even my IoT doesn't retain the SSID irradiated by Deco, and I need to rejoin all IoT individually, despite it's the same SSID

Any help will be appreciated.

NB if I setup NordVPN I lose SSID internet reason BTW is switched off
