Property Value Evidence
Controller SSD1677 Command set, LUT format (5x42 bytes), register layout
Diagonal 3.68" Alibaba listing + mechanical drawing; sqrt(51.84² + 77.76²) = 93.5mm = 3.68"
Buffer resolution 792 x 528 Constructor param, buffer size = 52,272 bytes (99 bytes/row x 528 rows)
Hardware resolution 792 x 600 CMD 0x61 data: [0x03, 0x18, 0x02, 0x58] → (0x0318=792) x (0x0258=600)

Monitor OPNsense internet connection

Monitor OPNsense internet connection

OPNsense sometimes "loses" the WAN facing connection when that is "reinitialised" (modem reboot/WAN restart).

Monitoring the WAN facing connection and taking corrective action is the solution proposed by this script.

opnsense_ping_check.sh will ping IP addresses to determine if the WAN connection is still working, and try to restore the WAN if needed by
