I recently implemented a new mesh wifi-network using the new Deco BE85 units. The characteristics are as follows:

• The main Deco unit is directly connected to the Zyxel modem/router (viber 1 GB up/down);
• I use a TL-Link switch for all the cat 5e ethernet lines throughout the house (POE is disabled for now);
• The other 2 Deco units are located on the first floor and attic using the ethernet backhaul;
• The network has been set to router mode first (love the features there), but now back to access point mode;
• I'm not using the Wi-Fi 7 or 6E features.

I've seen some strange behaviour for which I need your support:

• Apple HomePods (2nd gen and mini) drop off the network from time to time, always requiring a full factory reset when it happens. They just don't reconnect anymore once they drop off. I've tried using a fixed IP (Deco in router mode), disabling the mesh for these devices and even specifying a preferred Deco unit to connect to;
  They advised the network setup as I have implemented and described above;
• Downloading apps or iPhones updates does not work anymore, though regular browsing, watching videos etc. is working as expected. When I try to install or update an app for the IOS app store, it doesn't always succeed. It gets stuck when downloading. Same goes for downloading IOS updates. I have not been able to download an update (2-6 GB) after implementing the new network;
• Downloads from the internet fail from a Windows PC even if these are only 200-300 MB.

I'm looking for any help to stop me from returning the equipment. Thanks!
