I got my Px Mini Wifi about a month ago. It works like a charm, except for one thing. Every ten days or two weeks, it loses the WiFi connection with the home router. It happened two times so far. It can still be accessed via Hot Spot. In both times, I fixed the issue by disconnecting and then connecting the power. But this fix cannot be done when I am away from hope.

Can someone please guide me on troubleshooting this problem and how to fix it permanently.
