Hi everyone,
I'm experiencing a frustrating issue with multiple Samsung Galaxy Tab A9+ devices that I'm using as Smart Home control panels—one per floor in my house.
🔧 Setup Overview:
Each floor has its own Wi-Fi access point, using 2.4 GHz only
Different Wi-Fi channels per floor to avoid overlap
Static positioning: each tablet is fixed on the wall in kiosk mode using Fully Kiosk Browser
Internet access is allowed (even though it’s normally blocked in my setup)
Wi-Fi signal is strong and stable when connected
I have already blocked the MAC addresses of other access points to force the tablet to stay on the correct AP
❗The Problem:
The tablets randomly disconnect from Wi-Fi after a while
Once disconnected, they do not auto-reconnect
I need to manually toggle Wi-Fi off and on again, then they reconnect instantly
This happens even though “Keep Wi-Fi on” is enabled in Fully Kiosk settings
✅ Already Tried:
Full factory reset
Network settings reset
Checked AP settings (bandwidth, channels, DHCP, DNS)
Enabled all options in Fully Kiosk to keep Wi-Fi alive
Verified no power-saving settings are interfering
MAC randomization is disabled
Tried both static IP and DHCP
Once the tablet is connected, everything works perfectly for hours—but then the connection drops, and it doesn’t reconnect until I manually intervene. Since this happens on all tablets (on different floors and APs), I suspect it’s something with the tablet or Android 13/One UI behavior.
Has anyone else seen similar behavior with the Tab A9+ or Fully Kiosk? Any way to force auto-reconnect or at least detect + recover from dropped Wi-Fi without user interaction?
Thanks in advance!
