The LEDs NOT functioning.
e.g. Internet LED lights up green, even with cable to modem unplugged. WiFi LEDs did not light up at all...
No internet access of devices connected via LAN nor WiFi devices, even after multiple reboots of the router.
Unable to access the router via Firefox WebUI after initial configuration setup/changes and reboot to the router.
Used D-Link's crash recovery procedure to downgrade firmware to 03-27-2019-r39296 release for now.
Some users commented that version 03-22-2019-r39267 has been most stable but I had skipped testing that release...
