We have bought two Cubot Note 20 phones and we found they tend to disconnect from my Plusnet router (I have fibre).
With the following details I hope you can help me solve this problem.
The first day the signal was strong, but then the days after it gets weak (and most of the time stays so) and then both phones get disconnected most of the time.
Interestingly, whenever the two phones disconnect and reconnect they always do it at the same time, a sign that clearly indicates the router is causing this: after allowing connection of the two phones the very first time, then the router tends to reject them.
I tried to reset the router and, unfortunately, the issue occurs again and with the same pattern: at first the connection of the phones is powerful and stable, but then they tend to disconnect easily and continuously.
Both before and after resetting the router, however, I noticed that in the morning and afternoon the connection is a bit more stable, while in the evening it tends to be very bad. So maybe it also depends on how many people are using the internet service although no other devices were connected to our router. It seem as if Plusnet tends to discard additional connections when they need to provide more power for the large number of people connected at certain times of the day.
We also had this problem with our previous two phones (both Cubot Note 7) and we returned them. However, we didn't have this problem with the phones we had earlier (Cubot Note S), so it might be the connection between the new phones and the router...
Given the inconvenience of then having to reinstall all the apps after resetting the phones, I would only do the factory reset of both phones (in addition to resetting the router) if it is certain that this would fix the problem.
