Deco loses connection over network cable
I have 2 deco's in the house and one in the garden office, connected with a 20m ethernet cable to the main deco.
If I don't use the office, the deco wifi in the office is fine (there's a heater in that office that's connected to the wifi as well which I can check the online status of). However, when I am connected to the office deco's wifi with my laptop, pretty soon (usually within a day or so) the connection gets dropped.
At first (a while ago), I used to be able to solve it by just unplugging and plugging the cable on the main deco but this has stopped working. Now, rebooting deco's in different orders sometimes works but I have no idea what the problem is. For now, I've connected my laptop to the cable directly (and the cable to the router in the house, not to the main deco).
I have the impression that the laptop somehow brings the deco in a conflicting state it can't get out of, as the wifi stays connected fine as long as I don't use my laptop on it.
Anybody faced the same issue?
