Here is the info you requested:
Model: 5404X Insignia, Serial: SN007F728294, Device ID: 6JV617728294, Software OS: 10.5.0
No screen capture. It used to show Live TV on the main menu. Now when I go to main menu, if I chose the Live TV section (which is set up with an antenna), the system hold on the Live TV logo page, then goes black and the system appears to reboot (repeatedly) - the system drops WiFi, then tries to reboot.
The Roku, in general, appears to have issues with stability in the connection overall.
