Most of the time all works as it should, but I have encountered one website (to which I connect with the iPads) to which the connection is dropped after an hour or so usage.

 May I know which website did you refer to?

Response: The site and the latsest game I've attended is:

When you said the connection dropped, did you mean the whole Deco Mesh network dropped, like Deco M4 turned red? or only the wireless connection on iPad?

Response: I believe we are looking at the wireless connection to my iPad. Simultaneously my wife palys on her iPad with no problems.

As for your network map, I do have some questions:

For the ZyXel VDSL -modem, is it a wireless DSL modem router? and Can I have the model number of the Zyxel modem?

Response: No, it is a wireline modem connected to a VDSL -network access point and forming a router to the WWW from it. It comprises a wifi network (Koti_8880) and contains direct lines to which the first Deco M4 is connected and where the wifi from within the M4 (32a2wifi) is located. This wifi is the one I have problems with.

The model of ZyXel modem is VMG3925-B10B

Additional answers to questions on the picture are:

1. The Sector Alarm wifi is as far as I know embedded within it. If not, then it is the one labelled Koti-8880 residing on the ZyXel box and not part of the Mesh network.

2. The Elisa Viihde box is connected with a wire to the ZyXel -box. It links to the cloud service where the TV -recordings are managed.
