iplay 30 wifi randomly disconnects

Hi,

I recently bought an Alldocube iplay 30 pro and wifi disconnects randomly and the signal appears with a question mark after this disconnection, I am at 1 meter of my router and it cannot reconnect automatically, I have to turn the wifi of the tablet off and then turn it on again.

I have flashed the last firmware that I found in this web but the problem persist.

It's almost impossible to watch a video on YouTube at once... any solution for this?

I have more info about this issue, network state appears with messages:

NETWORK SELECTION TEMPORARILY DISABLED

NETWORK SELECTION DISABLED ASSOCIATION REJECTION

 

I didn't find a solution but this solve somehow the problem:

I have 2 wifi hotspots with diferent names close one each other, the solution was only configure 1 of them, if I config both the message and cuts appear

I tried this method but do not work for me. And I also tried to use both methods Randomized MAC and Device Mac both also don't work. Does anyone have the same experience?

Below is my firmware version.

I can work now with only 1 hotspot configured, I didn't change anything more, only DHCP enabled and using mac device.

One thing is clear, this device has an issue with wifi connections

Have same problem with wifi, what to do ? It is not possible to send this device back, because of China post, does not accept lithium batteries! What to do ?
