Yes I have too, device belongs in the scrap.
See the evaluation. These were the problems with it.

The problem is more serious for some, especially if you depend on this device for your Home Automation or Security.
In the event of a power failure, the Acer Predator Connect X5 cannot restart automatically. It is necessary to press the ON/OFF button.
According to the latest information from ACER, this is a problem that cannot be corrected by new firmware. Unfortunately, this is a hardware problem.
So, unless ACER replaces these devices with a blatant manufacturing defect and sends us a new device, our devices are not worth a damn for certain uses. That's a shame...

I don't have this problem, but the antenna is not very strong.
